Cool Metrics, Hot Results: How Data Transparency and Gamification are Supercharging HVAC Businesses

We live in the digital era. Today, there is more data and information accessible at our fingertips than ever before. HVAC contracting business owners are able to make smarter decisions based on data instead of just intuition. Some innovative contractors are even using data transparency with their teams to implement gamification, creating friendly competition and unity by working toward shared goals.

this company,’ are gone. It’s not our parents’ generation. There are so many opportunities today that you jump ship at the first sight of something interesting. So having something like gamification lightens up the mood within the office and makes things feel a lot more fun. And, obviously, labor shortages require businesses to focus more on retention and motivation.”

Gamification strategies can be used to motivate employees using leaderboard displays ranking technicians, CSR and dispatch teams based on KPIs, such as sales, jobs completed, and Google reviews.

“You can have achievement and badges automating recognition for milestones, such as most jobs completed in a week, highest revenue of the day, employee of the month, etc.,” Chow explains.

“You can have challenges, contests, and weekly competitions for highest upsell conversions or fewest callbacks — it could be anything. “

A multi-location HVAC contracting company in the Southeast uses Plecto to track revenue per technician, maintenance plans sold, and customer feedback scores. The results were a 31% increase in maintenance plan sales and a 20% increase in positive customer reviews, Chow notes.

The application of game design elements in a nongame setting has existed since the early 2000s; however, it has started gaining serious attention within the last five years, according to Andrew Chow, senior partnership manager at Plecto — a company-wide solution tracking KPIs that lays the foundation for a performance-driven work culture.

“I can see during my demos with trades guys that the gamification features I’m presenting are not foreign to them,” Chow says. “They are already running things like spiff programs manually. Plecto is making it more accessible and more actionable in a digital format. It’s becoming more popular because Gen X and Gen Z expect engagement and feedback loops. Basically, our attention span is a lot lower today. So having these gamification features for the younger generations really helps, because the days of loyalty, ‘I’m going to die and fight for

The data and leaderboard displays are more of a stick, so where is the carrot for employees? Contracting business owners can create an in-app economy using Plecto coin (think Bitcoin or other digital currency). Every time an employee achieves something, they get rewarded with a certain amount of Plecto coins of the owners’ choosing, depending on the achievement. Once an employee has gathered enough coins, he or she can use them to claim a prize from the reward store. Chow says some contractors have placed Amazon gift cards, gift certificates to local restaurants, lunch with the boss, or even a new vehicle!

Incorporating gamification and data transparency into HVAC operations isn’t just a tech trend — it’s a strategic advantage. By turning performance metrics into clear, engaging goals, contractors can boost team motivation, improve accountability, and drive consistent results.

“Every department used to work in silos, but having data transparency across all departments allows everyone in the company to be aligned with the same mission and goal,” Chow says.

Service Experts Helps Renovate Florida Veteran’s Home

WEST PALM BEACH, Florida—Veterans and team members from Service Experts joined the national home improvement series, “Military Makeover with Montel,” airing on Lifetime TV, a show dedicated to honoring veteran families through transformative home renovations. The latest episode honors Christy LaVallee, a proud recipient of the Purple Heart.

“This renovation was particularly rewarding for us because local members of our ServiceExperts team, who are themselves veterans, were able to participate,” said Bill Selman, general manager of Service Experts South Florida, who was also among the “boots on the ground” for the company. “At Service Experts, we’re deeply committed to supporting the military community as employers and members of the community.”

After enlisting in the Army, LaVallee served a notable deployment in Kandahar, Afghanistan from 2010 to 2011, and

achieved the rank of Specialist in the Army Reserves. Her role as a combat support military police officer exposed her to a harrowing IED blast that left a lasting impact. She received several commendations in recognition of her bravery, including the Purple Heart, Combat Action Badge, and multiple campaign and service medals. She was left with PTSD, hearing loss, and mobility issues, but has remained committed to her community, demonstrating a profound sense of resilience and dedication that her partner, Abbey Roberts, admires. Now working as a scheduling dispatcher, she continues to make a positive impact through her dedication and service.

With the help of the 15-member Service Experts team drawing from 10 local Service Experts centers, which included George Ahearn, an Army veteran and recipient of The Purple Heart himself, Service Experts performed electrical, HVAC, and plumbing work.

“Military Makeover is a great program, and it was an honor to be a part of this for both myself and for Service Experts,” added Ahearn. “As a prior service member, it was a privilege to help out a veteran.”

PHCC Foremen Workshop Highlights AI and Innovation for Field Leadership

BROOMFIELD, Colorado—The role of the foreman is evolving, a fact demonstrated clearly at the Plumbing-Heating-Cooling Contractors—National Association (PHCC) Educational Foundation’s recent Creating Super Foremen workshop, held May 2–3 at the Viega Seminar Center in Broomfield, Colorado. With instruction led by Purdue University Professor Emeritus Kirk Alter, the event brought together 27 foremen from contracting companies nationwide for an immersive two-day training experience.

This year’s program emphasized the foreman’s critical role as the first line of company management; the individual on the jobsite responsible for aligning field performance with their company’s business goals. A key part of that alignment

With the help of the 15-member Service Experts team drawing from 10 local Service Experts centers, which included George Ahearn, an Army veteran and recipient of The Purple Heart himself, Service Experts performed electrical, HVAC, and plumbing work. Service Experts

is leveraging technology and innovative tools to drive communication, planning, and accountability.

In one standout activity, attendees worked hands-on with an artificial intelligence platform to build a career progression roadmap for a new hire, outlining a clear path from apprentice to journeyman to foreman. The incredibly detailed eight-year plan featured technical and soft skills to be mastered each month, plus quarterly goals, and structured evaluation checkpoints. Participants also used AI to craft messaging to address concerns they would hear from an 18-year-old considering a career in the trades such as the perceived length of time it takes to grow into a leadership role. The generated answer compared the extended training process to pressure testing an incomplete piping system; explaining that it takes time to ensure that all the necessary pieces fit together properly.

“You are used to being the most productive field worker on your job,” Alter told the attendees. “But now as a foreman, you are getting paid to help the members of your crew to be the most productive workers on that jobsite. Your tools are now your computer and your brain. And you are seeing how A.I. is another incredibly powerful tool that you must learn how to use to be successful today.”

In addition to exploring new technologies, the course also reinforced the importance of thorough planning, clear documentation, and ongoing communication with office staff. These foundational skills allow foremen to provide timely updates that help project managers and contractor business owners make informed decisions and deliver the support needed to complete jobs efficiently and profitably.

SurvivAL Guide HVACR Contracting

Mid-Year Outlook:

Exclusive

Q

& A with leading experts, to guide you through the second half of 2025!

The first half of 2025 has been a perfect storm for the HVACR industry as contractors have navigated tariffs, shifting regulations, evolving technologies, and consumer caution.

To get a clearer picture of where things stand— and where they’re headed—Contracting Business spoke with leading OEMs to gain insights on the biggest challenges and opportunities facing the industry today. Shane Angle, vice president, sales and technical services, Copeland; Scot Swan, business manager, Arkema; Doug Widenmann, senior vice president of marketing, Daikin Comfort Technologies North America; and Randy Roberts, vice president, Residential, Rheem Air Conditioning Division, offer mid-year perspectives and valuable guidance for contractors planning the months ahead.

CB: Are you seeing increased pricing for HVAC systems with the current economic climate and tariffs in place, and how is that affecting demand?

Angle: We’ve seen only marginal pricing increases from tariffs so far. Overall, the pricing of HVAC systems has increased significantly over the past five years, starting with the supply chain challenges brought on by COVID-19. Also, remember that this is the first year of a transition in residential air conditioning. Since Jan. 1, 2025, all new units produced have been

optimized for A2L refrigerants, resulting in a slight additional price increase due to the design changes needed.

Since the start of April, we have seen additional system price increases in the 5% to 10% range due to tariff uncertainty. We could anticipate additional increases depending on how the negotiations on reciprocal tariffs with China play out.

It’s too soon to know if there may be an impact on demand, although the price increases over the last five years haven’t had a dramatic effect. If air conditioning or heating units break, consumers will get them fixed, whether it’s a system repair or replacement.

That said, we do anticipate a potential shift in the repair-replace decision this year. One reason is the economic uncertainty and price increases. We’ve also historically seen some resistance during refrigerant transitions to embrace the new, optimized units. So, some may upgrade to a new R-410A compressor as a cost-effective measure for keeping an existing system running. Copeland has prepared for either scenario by preparing for the refrigerant shift with a full lineup of A2L-optimized compression options. We’ve also recently introduced a line of Copeland LXE service compressors that consolidate R-410A compressors (i.e., ZP**KA/KV/K5/K6/ K7) into one platform. Not only is this platform optimized to be our most efficient R-410A compressor, but it also helps ensure availability at

“We do anticipate a potential shift in the repair-replace decision this year. One reason is the economic uncertainty and price increases.”

— Shane Angle, Copeland

the point of service, simplifies support of legacy refrigerant compressor-based systems, and reduces the number of SKUs for our distribution partners.

Roberts: Due to the current economic climate and tariffs, Rheem is seeing increased costs for raw materials and components used to build HVAC equipment. While these cost pressures are a reality, so far, it hasn’t had a direct impact on demand.

“We see the HVAC market continuing to evolve with a strong focus on efficiency, electrification, and decarbonization, even as economic conditions remain uncertain.”

Widenmann: Yes, various OEMs have announced price adjustments in response to the global trade situation. We have announced price adjustments and continue to monitor the situation very closely. However, we believe there are other factors also affecting demand, such as other OEMs’ A2L refrigerant transition, that appear to be an opportunity for Daikin.

— Randy Roberts, Rheem

CB: How are you managing supply chain disruptions to ensure contractors and distributors receive equipment on time?

Roberts: While Rheem is seeing some supply chain disruptions, particularly as suppliers adjust production locations to navigate tariff impacts, the company has taken proactive steps to minimize delays. With multiple vendors, Rheem has built flexibility into its supply chain, allowing the company to better manage through potential disruptions and continue delivering equipment to contractors and distributors on time.

Widenmann: Daikin has been working on various strategies since the supply disruption the industry experienced beginning in 2022. We believe that our state-of-the-art manufacturing facility, Daikin Texas Technology Park, in Waller, Texas, our comparable logistics operations at Daikin, and our supplier localization efforts are well situated to meet the anticipated growth opportunities ahead of us. Also, choosing to transition to R-32, ahead of many other OEMs with R-454B, has allowed us to strengthen our inventory position with a proven, available, low-cost refrigerant, compared to other available

low-GWP refrigerants used in residential and light-commercial systems.

Angle: Mitigating supply chain disruptions has been a longstanding area of continued focus and commitment for our business. We’ve made strategic investments in our supply chain and inventories to help ensure we continue improving resiliency and redundancy to protect against potential supply chain disruptions. Over the last decade, we’ve identified opportunities to invest in regionalizing our supply base in North America, reducing reliance on foreign suppliers, and establishing strategic regional locations of factories and assembly plants. These efforts will continue.

Today, we have manufacturing plants in over 25 facilities worldwide, including in the U.S., India, East Asia and Mexico. This broad footprint allows us to stay close to customers and ensure faster lead times.

CB: How is the transition to A2L refrigerants progressing, and are there any supply chain concerns affecting availability?

Swan: The transition was delayed due to OEMs producing 410A equipment later in 2024 than originally expected. Now it’s likely that 410A equipment will not be sold through until mid-2025. So we expect that the new equipment will become increasingly available later in 2025. To our knowledge, those that are using R-32 equipment are not experiencing supply chain issues.

The industry was well aware of the move to A2L refrigerants for a number of years, but there has been uncertainty on exactly when OEMs would transition their product lines. Presently, the supply

“We expect that the new [A2L] equipment will become increasingly available later in 2025.”
— Scot Swan, Arkema

chain pipeline for A2L refrigerants is being filled. In the case of R-32, because there was an earlier start, the product is more readily available.

CB: What steps are refrigerant manufacturers taking to ensure contractors have adequate access to A2Ls during the transition?

Swan: Arkema has been preparing for this transition for several years. It started with our OEM partners. More recently, we’ve worked with our package suppliers to ensure we could meet market demand for R-32. Finally, we continue to work with knowledgeable others such as ACCA to ensure contractors have the training they need to work safely with A2Ls.

CB: With the Trump administration focusing on deregulation, are decarbonization and electrification still major trends in the HVACR industry? Why or why not?

Widenmann: Absolutely. Much of the activity to advance heat pump deployment in the past few years has been driven at a state level versus federal level. While the federal government may be unlikely to pursue a decarbonization/electrification strategy in the next four years, we think that it could result in more aggressive action at the state level.

Angle: Decarbonization and electrification are significant global trends regardless of what’s happening politically in the U.S. As an international company, we serve a global economy. Thus, worldwide transitions—including decarbonization and electrification efforts—will continue to guide our business.

In the U.S., decarbonization and electrification are also being led at the state level. So, even if the federal government retracts efforts, we would anticipate states to fill those gaps, and in some cases, propose and implement additional efforts.

The HVACR industry relies on certainty and predictability to make the necessary investments to ensure these advancements continue. Equipment manufacturers must always consider their customers’ best interests, which means balancing safety, reliability and cost-effectiveness of their products while transitioning to next-gen technologies. Thus, pace and timing are paramount when establishing and implementing guidelines and rulemaking, including those around electrification and decarbonization.

Roberts: Yes, decarbonization and electrification remain major trends in the HVAC/R industry. While regulatory environments can influence the pace of certain initiatives, the drive toward

lower carbon emissions and more energy-efficient systems is being driven by consumer wants. Commercial building owners and residential customers are prioritizing energy-efficient HVACR solutions for environmental reasons and long-term cost savings.

At Rheem, we’re committed to innovation that supports decarbonization and electrification. This includes expanding our portfolio of high-efficiency, low-emissions equipment and investing in training to ensure contractors are equipped and understand the latest sustainable product offerings. In addition, Rheem will continue to invest in its gas product lines to be ready no matter which direction the market shifts. We also see dual-fuel solutions as a great method to move into a heat pump solution for markets that were historically gas.

Swan: It’s likely to continue to be a major trend, especially for air-sourced heat pumps. It will vary more so at a state by state level in terms of newer technologies like air-to-water heat pumps and heat pump water heaters. These technologies are much more dependent on state and/or federal incentives.

CB: What is the largest trend impacting the HVACR industry to date, and what is driving that trend?

Angle: The most significant trend impacting the HVACR industry has been transitioning from legacy hydrofluorocarbon (HFC) refrigerants to lower-global warming potential (GWP) alternatives. Today, contractors are beginning to install new residential air conditioning and heat pump equipment optimized for A2L refrigerants. However, the cumulative workload, effort, capital and resource investments needed to make these units available have been monumental. Our industry has worked overtime for two to three years to prepare for this transition.

Meanwhile, preparations are underway to transition refrigerants such as A2Ls, CO2 and R-290 in many more U.S. HVACR sectors over the next several years. This is not the first refrigerant transition our industry has seen, but it’s the first time it’s happened at such a large scale and over a short period of time—and it’s all part of a global HFC phasedown.

The refrigerant transition is also happening while the global economy sets decarbonization and electrification goals. Copeland actively invests in and supports the energy transition from gaspowered space and water heating systems to electric heat pump technologies. This global megatrend is already underway, but we anticipate it to become a much larger focus over the next decade and beyond.

Roberts: One of the largest trends currently impacting the HVAC/R industry is the transition to A2L refrigerants, and it’s reshaping everything from product design to contractor training. For OEMs, this has meant reengineering systems to safely accommodate A2Ls without compromising performance or reliability. For contractors and technicians, it means adapting to new tools, safety standards and certification requirements. The A2L

transition is part of a broader industry push toward decarbonization and electrification, and Rheem has been at the forefront of this transition for years.

Swan: Regulations are still the most impactful force in the industry. For instance, DOE standards may be relaxed but the industry is still working to catch up. EPA regulations on refrigerants may or may not be relaxed which could heavily impact the level of adoption of next generation refrigerants.

Rapid changes in Regulations are still the number one challenge whether at the federal level or the state level.

Widenmann: There are a few different trends, of which some are short term and others are long term. In the short term, the refrigerant transition is currently on every manufacturer’s, distributor’s, and contractor’s mind. Daikin made many tough choices and made what we consider the harder right decisions when it came to reengineering our new products to obtain optimal performance from the new R-32 low global warming potential refrigerant – we have redesigned every product while providing technology advancements and industry exclusive products for North America. Daikin has and continues to be a leader in technological advancements in inverter technology worldwide and in North America which has led to the current and anticipated continued shift from fossil fuel burning gas furnaces to electrification with advances in inverter heat pump technology.

CB: How do you see the HVAC market evolving over the next 1-3 years given current economic conditions?

Angle: It’s difficult to predict, but we could see an evolution in market conditions that may favor specific technologies. For example, variable refrigerant flow (VRF) systems, which were already facing headwinds with the adoption of A2Ls and concern about plumbing flammable refrigerant charges throughout a building, may now also be impacted by the China-U.S. tariff uncertainties and potential price increases. As a result, end users or contractors considering VRF systems may opt for a more traditional ducted system.

Again, we could also see a shift in the repair-replace decision, driven by potential price increases and hesitance over transitioning to a new refrigerant. In the face of these real or perceived headwinds, end users and contractors may prefer to prolong existing systems with strategic repairs.

Roberts: Over the next 1–3 years, we see the HVAC market continuing to evolve with a strong focus on efficiency, electrification, and decarbonization, even as economic conditions remain uncertain. From Rheem’s perspective, we’re investing heavily in training and product innovation to help our partners navigate this evolving landscape.

Widenmann: Technology improvements in advanced energy efficiency, sustainability, decarbonization and smart, connected systems will continue to be an ongoing trend driven by higher utility costs and movement toward replacing fossil fuel based heating

systems. Successful contractors will focus on value, operating cost and lifetime cost, while becoming more technologically advanced in the equipment and technology they offer as well as more advanced in how they promote affordability of more efficient HVAC systems they sell through creative lending and utilization of incentives.

CB: What advice do you have for HVAC contractors and distributors to navigate economic uncertainty?

Angle: Our best advice is to stay calm, not overreact, and not undermine our industry’s technological advances and sustainability progress. We’ve experienced these economic and regulatory uncertainties before and know that the wheels turn slowly. Unlike some other sectors, HVACR products are fundamental to our ways of life—comfort cooling/heating, process cooling/heating or refrigeration—and are inherently more resilient to disruptions.

We will likely see new updates and unexpected developments over the next months, and we recommend keeping an objective viewpoint about the potential implications. For our part, Copeland is committed to mitigating supply chain disruptions with increased resiliency and redundancy, while helping the industry make sense of any changes that may be on the horizon.

Roberts: Stay informed, flexible and focused on delivering value to your customers. This means keeping up with industry changes, investing in training, and staying ahead of product and regulatory shifts, like the transition to A2L refrigerants. Contractors should position themselves as trusted advisors, helping customers understand the changing landscape. Distributors should prioritize strong supplier relationships and smart inventory planning to stay ahead of market needs.

Swan: Don’t buy ahead. Recognize that if prices are too good to be true, they probably are. Make sure that you buy from reputable sources.

Widenmann: Don’t assume that how and why HVAC systems are purchased today will be the same tomorrow. Consumers are challenged, but they have not abandoned their buying preferences. They have become savvier with knowledge at their fingertips. Don’t race to the bottom with price. Yes, consumers want affordability, but they also want choices, comfort, efficiency and technology.

UV-C Monitoring Helps Ensure HVAC Efficiency and Energy Savings

Timely UV lamp replacement and ongoing monitoring helps ensure consistent and optimal system operation.

Ultraviolet light has been used since the 1990s to enhance HVAC efficiency, improve air quality, and reduce energy consumption. Germicidal UV technology has attracted attention since researchers demonstrated that UV‑C can reduce airborne pathogens in occupied spaces. In 1937, epidemiolo gist William F. Wells installed UV lamps in Philadelphia schools and lowered measles infection rates to 14.5% compared to 55.3% in schools without UV‑C.

Today, the focus continues to evolve. This article delves into the mechanics of germicidal wavelengths—specifically tra ditional UV C (254 nm), UV C LEDs, and the emerging Far UV (222 nm)—and how these tools impact HVAC performance. It also explores the critical importance of timely UV lamp replacement and ongoing wavelength intensity monitoring to en sure consistent disinfection performance and optimal system operation.

Understanding UV-C in HVAC Systems

UV‑C, or energy in the C band of the UV spectrum (200–280 nm), is the most widely used and extensively studied

Inactivates bacteria, viruses, and mold by damaging their DNA or RNA, preventing replication.

Properly designed and certified systems can be safely used in occupied spaces.

Offers energy efficiency, durability, and tunable wavelengths but generally has lower intensity.

GERMICIDAL UV WAVELENGTHS

airborne and surface-bound microbes, including chickenpox, measles, mumps, tuberculosis, and cold viruses. While the rise of antibiotics led to a decline in germicidal UV use, the 1990s saw a resurgence due to growing concerns over drug-resistant pathogens and hospitalacquired infections. This re-establishment of germicidal UV- C among infection control preventionists underscored the wavelength’s ability to inactivate virtually any microorganism at the appropriate dose.

ASHRAE has recognized that UV- C wavelengths can inactivate up to 90% of microorganisms living on HVACR surfaces, depending on the UV- C intensity, exposure length, and operational conditions. More recently, the U.S. Centers for Disease Control and Prevention recommended UV- C and mechanical HVAC filtrations as two primary technologies that can “improve air cleanliness in the workplace.”

Enhancing HVAC Efficiency and Energy Savings

Microbial and biofilm growth on HVAC components, such as coils and drain pans, can lead to coil fouling/clogging, reduce HVAC efficiency, and increase (fan/blower) energy consumption. The buildup of organic contaminants obstructs efficient heat transfer by creating an insulating layer on the coil, preventing warm air from effectively exchanging its heat with the coil.

By breaking down and removing organic buildup and biofilm from HVAC coil and fin surfaces, UV-C energy helps preserve the coil’s “open area”—the interstitial space between the fins—ensuring strong airflow and maximizing heat exchange performance.

An ASHRAE field study found that exposing a fouled cooling coil to UV-C improved heat transfer efficiency by 14.55% and decreased pressure drop (airflow resistance) by 10%. Other benefits include:

• Improved Heat Transfer: Clean coils facilitate better heat exchange, allowing the HVAC system to reach desired temperatures more efficiently;

• Reduced Pressure Drop: Eliminating microbial buildup

minimizes airflow resistance, ensuring optimal air circulation and reducing the workload on fans and motors; and

• Lower Energy Consumption: Enhanced heat transfer and airflow efficiency reduce energy usage, leading to cost savings and a smaller carbon footprint.

The Importance of Timely UV Lamp Replacement

Germicidal effectiveness in HVAC applications depends on UV- C energy and exposure duration.

Like any bulb, UV- C lamps eventually burn out. However, only 20–30% of building engineers routinely replace their lamps. This happens for two key reasons: 1) UV-C lamps are often installed out of sight in hard-to-reach air handlers, making maintenance easy to forget, and 2) engineers see the lamp’s blue glow and assume—incorrectly—that it’s still maintaining HVAC efficiency and improving IAQ.

A common misconception is that a bluish glow means a UV-C lamp is still effective, but visible light persists long after germicidal intensity drops below functional levels. The bottom line: Building

engineers cannot rely on visual inspec tion to determine whether HVAC/R com ponents are disinfected, as UV‑C energy is beyond the range of visible light, meaning you cannot see it.

Most lamp manufacturers (Signify, GE, Sylvania, etc.) recommend replacing UV‑C lamps after approximately 9,000 hours of operation, or, since there are 8,760 hours in a year, most facility managers employ an annual re lamping / preventative main tenance schedule.

Replacing lamps when their output de creases by 20% is typical, usually occurring between 12 15 months. Lamp change outs should be performed for mission critical treatment, such as infectious disease or healthcare applications, using a calibrated laboratory radiometer or UV monitor.

Advancements in UV Monitoring

Facility engineers increasingly use contin uous monitoring systems and dashboard reporting metrics to streamline UV‑C HVAC maintenance.

If a lamp or ballast fails, the UV monitor alerts the user, helping ensure the applica tion meets the UV output levels specified by design engineers or application re quirements. Automating UV‑C monitor ing also eliminates the need for facility managers to manually check individual lamps and ballasts. With UV‑C fixtures often spread across multiple HVAC AHUs, roof top units, and locations, automated

verification cuts labor costs and helps doc ument operational or germ inactivation efficiency. Most UV monitor interfaces and reporting dashboards easily integrate with building automation and management sys tems (BAS/BMS).

Key features of most UV monitors include:

• Predictive Maintenance and Automated Alerts: BAS/BMS integrated UV monitoring enables predictive maintenance checks. Facility managers can receive automated alerts when a UV lamp is nearing the end of its lifecycle, re ducing the risk of system downtime;

• Comprehensive Monitoring: Some UV monitors are equipped with sensors specifically configured for the UV‑C, LED UV, and Far UV wavelength, ensuring accurate de tection of lamp performance across the spectrum;

• Prompt Alerts: UV monitors promptly notify users of any changes in lamp output, enabling timely adjustments and mainte nance actions to sustain optimal performance.

UV monitors enable facility engineers and building managers to proactively manage UV‑C systems, ensuring consis tent pathogen control and optimal HVAC efficiency.

UV monitoring systems align with the objectives of ASHRAE Standard 241, which

establishes minimum requirements for reducing the risk of disease transmission through exposure to infectious aerosols in buildings. By ensuring that UV disinfection processes remain effective, today’s moni tor technology consistently supports clean air and contributes to the overall health of building environments.

As clean air becomes a critical compo nent of healthy, energy efficient buildings, UV C technology and smart monitoring systems will continue to play a founda tional role in the future of HVAC design.

Conclusion

By effectively disinfecting airstreams and preventing microbial buildup on critical components, UV‑C technology contributes to significant energy savings and reduced maintenance requirements. Adhering to a strict UV lamp replacement schedule of 9,000 hours or one year is crucial to maintain the specified UV‑C fluence necessary for effective disinfec tion. Furthermore, leveraging advanced UV monitoring systems ensures germi cidal installations operate at peak per formance, providing healthier and safer environments for building occupants.

Enhancing Comfort and Efficiency with Radiant Cooling Systems

High-performance trends and research on radiant cooling systems.

Radiant cooling systems are gaining popularity in modern buildings due to their numerous benefits, including enhanced comfort, low maintenance, improved indoor air quality,

greater energy efficiency, reduced operating costs, and architectural versatility.

By using radiation to maintain indoor thermal comfort with lower energy consumption, these systems provide stable

temperature control and reduce reliance on forced air, contributing to a quieter, healthier indoor environment while working in tandem with ventilation for optimal air quality.

The University of Washington Life Sciences Building in Seattle is comprised of 167,000 square feet of offices, labs, and classrooms, as well as a 20,000 square foot greenhouse. Because of the high solar gains of floor-to-ceiling windows, the radiant system was installed in the concrete slab on the southern and northwestern sides of the building, primarily for main entrances, lobbies, coffee shops, seating

areas, professors’ offices, and graduate student work areas. The 23,000 square foot area covered six levels and used 49,000 feet of 5/8-inch REHAU RAUPEX O2 barrier crosslinked polyethylene (PEXa) pipe with 6-inch on center spacing, 146 circuits, and 19 PRO-BALANCE manifolds. Overhead, chilled beams and radiant ceiling panels from other manufacturers provide additional hydronic cooling.

The article below will delve into highperformance trends and the latest research on radiant cooling systems, exemplifying how they can enhance the well-being and comfort of those who spend time in these buildings.

Principles of Radiant Cooling Systems

HVAC systems that transfer more than 50 percent of heat through radiation can be classified as radiant systems. The most common types include ESS (Embedded Surface Systems), where PEX piping is embedded in concrete thermal mass or surfaces like floors, walls, or ceilings, and radiant ceiling panels, where pipes are attached to the back of the ceiling panels.

Heating mode raises the surface temperature until it begins to radiate heat toward the occupied space, increasing the mean radiant temperature. In cooling mode, the system absorbs heat from the space by lowering the average surface temperature of the room, as warm surfaces always radiate heat to cooler ones.

“Unlike forced-air systems, radiant cooling delivers uniform temperatures without drafts or uneven airflow, a common issue in office buildings, so you’re less likely to need a sweater in the middle of summer.”

A hybrid system is needed because radiant systems handle sensible loads but cannot control humidity or manage latent cooling load. A Dedicated Outdoor Air System (DOAS) addresses these needs by providing fresh air and controlling humidity to meet ASHRAE 62.1 standards. Hybrid systems also offer flexibility during heating-to-cooling changeovers or shifts in occupancy, ensuring optimal comfort and ventilation.

Thermal Comfort

Comfort is more than just a thermostat setting; it’s influenced by a combination of internal and external factors from ASHRAE 55: air temperature, air speed, humidity,

The University of Chicago North Residential Commons features 300,000 feet of radiant heating and cooling piping: The building’s common areas are heated via a traditional forced-air system, while the student living quarters use REHAU in-slab hydronic radiant heating and cooling. By circulating heated or chilled water through 5/8-inch PEXa pipe installed in the ceilings on each floor, the hydronic system maintains the spaces at even, comfortable temperatures while using less energy than traditional forced-air systems.

metabolic rate, clothing insulation and mean radiant temperature.

Hybrid radiant systems enhance comfort by actively regulating mean radiant temperature and operative temperature, key metrics used in thermal comfort standards, including those referenced in LEED. By absorbing heat through radiation, these systems reduce reliance on excessively cold air for cooling. Unlike forced-air systems, radiant cooling delivers uniform temperatures without drafts or uneven airflow, a common issue in office buildings, so you’re less likely to need a sweater in the middle of summer!

System Efficiency

Radiant cooling systems are highly efficient, reducing a building’s total energy use by operating at higher cooling setpoints. They also use warmer chilled water temperatures, improving chiller efficiency, making them ideal for heat pumps or renewable sources. Water stores 3,400 times more thermal energy per unit volume than air, and circulating it uses 75–90 percent less energy than moving air with a blower fan while reducing transmission losses. Additionally, these systems offer thermal storage potential to reduce peak loads and shift operation to off-peak hours, further enhancing efficiency.

A research study by the New Buildings Institute on site energy use found that radiant buildings are more energy-efficient than 90 percent of comparable buildings, with two-thirds achieving an EnergyStar score of 90 or higher. The study also highlighted that data from two independent studies revealed that most net-zero energy buildings incorporate radiant systems. This suggests that top designers recognize radiant systems as a key strategy for achieving low-energy performance.

Impact of Solar Gain and Ceiling Fans

Maximum radiant cooling capacity under standard conditions is about 40-50 W/ m2 [13-16 Btu/h.ft2], which is limited by relatively small heat transfer coefficient between active surfaces and air. Also, low floor temperatures increase risks of condensation and occupant discomfort. Studies have shown that radiant cooling capacity significantly increases under direct sunlight, reaching >100 W/m2 [>31 Btu/h.ft2].

When paired with radiant cooling systems, ceiling fans promote more building efficiency, improved air quality and cooling properties. A Computational Fluid Dynamics (CFD) simulation was conducted by CBE (Center for Built Environment)

“Radiant cooling systems are highly efficient, reducing a building’s total energy use by operating at higher cooling setpoints.”

to examine how heat transfers between a cooled floor or ceiling and the surrounding air. The results in the study showed that using a ceiling fan to enhance air movement improved airflow within the room, boosting natural convection and increasing the efficiency of the radiant cooling system. In fact, the study found that greater air movement could

enhance radiant cooling capacity by up to 30 percent.

Design Opportunities

Radiant cooling systems offer a versatile and energy-efficient solution for various applications, including schools, offices, hospitals, and spaces with large glazed surfaces such as atriums, airports and transit hubs. With proper design and controls, condensation risks can be effectively managed in most climates.

Strategic load shifting enhances efficiency by allowing DOAS and radiant cooling to operate at different times and temperatures using the same heat pump. Additionally, the ability to run at warmer supply temperatures enables cooling tower economizer operation, further reducing energy consumption.

Conclusion

With increasing electrification and decarbonization efforts, radiant cooling’s ability to integrate with heat pumps and renewable energy sources positions it as a key technology for high-performance buildings. Research shows that radiantcooled buildings consistently achieve top-tier energy performance, making them a proven solution for the future of sustainable design. By reducing peak loads, minimizing energy consumption and enhancing occupant comfort, radiant cooling continues to gain traction as a reliable and forward-thinking approach to modern building systems.

How and Why the HVAC Industry Can Appeal to Young People

The HVAC industry is attracting Gen-Z with varied career paths and lucrative salaries, offering an alternative to traditional four-year college education.

The labor shortage in the trades has been reported on ad nauseam for years. However, the tide seems to be turning with Gen-Z leading the way. The HVAC industry is also experiencing an upturn in young people joining its ranks. Many focus on college costs. However, the answer goes further.

Wider Diverse Career Path

In the past, when contractors were primarily small companies, there were limited career paths available in HVAC. Young people entered the industry, and the only future

opportunity was to buy the company you started with or start your own.

Not today.

As Private Equity (PE) has become entrenched in HVAC and larger companies have emerged in the industry, various options have arisen.

“PE brought the career path concept—where you start as an apprentice, move to installation, and then either service or installation manager, then general manager, to owning your own business one day—to HVAC,” says Jim Hinshaw, a vice president of sales at Service Nation.

“The opportunities are endless between those involved on the labor end and back office.”
— Angie Snow, ServiceTitan

Angie Snow, a principal industry advisor for ServiceTitan, adds, “The opportunities are endless between those involved on the labor end and back office.”

Young people appreciate the variety of opportunities. “There’s usually something for everyone,” says 18-year-old Brandon Snow (Angie Snow’s son). Snow, an HVAC installer at Western Heating, Air & Plumbing, adds, “If you don’t like one position, there’s another spot in the field or office that you might like.”

Larry Shoemaker is a branch manager with Haller, director of education for the Plumbing-HeatingCooling Contractors Association (PHCC), and a former HVAC company owner. When Shoemaker talks with high school-aged students, he asks them about the type of position they’re looking for.

“I encourage them to consider the pathways that the workplace offers and if there’s room for growth. When I owned Deluxe, I had nowhere to grow them. With HomeEx (parent company of Haller) there are tons of opportunities that aren’t available in a momand-pop shop.”

Good Salary

When you were young, your parents and other adults may have said: If you want to be well-paid, go to college. You’ll never make much money from the trades. That thinking is outdated. Jobs in the trades can also be high-paying. And young people are getting the picture.

Hinshaw reflects. “A successful business owner comes on stage in front of a crowd of techs and installers and showed three huge posters. A Hummer, Jaguar, and a RestoMod Ford. He said, ‘these are not my cars, these are cars my team of service techs and installers own. That is the kind of money that can be made in this industry.’

“It was the best pitch I ever saw as the crowd was in awe.”

It’s not just outliers who are making good salaries in HVAC. Technicians can start at $60,000 and quickly move on to higher-paying salaries, depending on their path.

“I had an HVAC tech come in four years ago as part of the coop before going full time,” Shoemaker says. “He’s now 22 and in a sales position while on the way to making $300,000 in bonus and salary.”

Going into HVAC, rather than attending a fouryear college, also saves young people and their families from huge four-year college tuition costs. “Word is getting out about how much you can make and that you don’t have to go to college,” Angie says. She encourages parents of young people considering HVAC, “If you’re worried about your son/daughter making money in HVAC, don’t. The opportunities are there.”

Influencers/Cool Factor

Authorities asked Famous thief Willie Sutton why he robbed banks. He responded, “Because that’s where the money is.” Many young people are very into social media and YouTube.

Paige Knowles, i.e., Plumber Paige, is a 20-something who entered the trades after falling in love with the work while helping her parents maintain their rental properties.

Knowles interned in the trades during high school (she later attended college for construction management and has an HVAC degree) and quickly realized there was little support for the younger generation interested in the trades. Her goal is to expose young people to the positive elements of the trades.

“I want to end the stigma around the trades, especially for women, and let them know there’s a place in the trades for them,” Knowles says. “People think it’s all hard, dirty work, but the trades are desirable work and offer rewarding career paths where you can make lots of money and do meaningful tasks.”

Knowles, who works part-time for an HVAC company, has a growing social media presence and has authored three books for younger people. She has spoken to crowds of up to 5,000 people as part of her quest to make the skilled trades cool again.

Social media is just one way to entice young people to consider HVAC.

Brandon Snow got into the industry through his parents’ company and found out he enjoyed the experience and liked the people. “While I follow some influencers on TikTok, like Fat Cheeto, they’re not the real reason I’m so interested. It’s more the people who have taught me a lot about the trade and the company that I work for that keeps me motivated.”

What else can HVAC companies do to attract young people?

“Examine your business and consider how appealing it is to Gen Z,” Angie Snow says. “Up-to-date technology, an active social media account that shows fun culture, and living your values appeals to young people.”

The goal — create buzz.

Conclusion

The challenge of filling the pipeline in the trades is real. Many studies project that the need will grow more dire as the last of the baby boomers retire. If the uptick of those entering HVAC from Gen Z continues and grows, they will minimize the hole in the market.

Prioritizing Safety in HVACR Contracting: Strategies for Success

Top HVACR firms prioritize safety through rigorous training, mental health resources, and innovative orientation programs.

Safety is one of the most important factors for HVACR contractors. At the end of the day, business owners want their employees to go home to their families. Safety can also lead to significant financial savings for firms by reducing workplace accidents, minimizing downtime, and lowering insurance premiums.

“Insurance is a big cost to doing business,” notes Justin Crandol, MS, CSP, ARM, CRIS, director of safety for Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA). “If you don’t have any safety or health policies in place, any insurance company is going to skittish in providing you with insurance.”

On the other end of things, if you’re safety program is not up to snuff, so to speak, your firm won’t even be considered for a project, according to Don Campbell, CHST, vice president of P1 Construction

LLC. Campbell just celebrated 23 years with his firm, and while he previously served vice president of safety, he is still the top safety official at the company.

“If you’re going to bid a project now, many of them require you to pass through a third-party qualifier to prove your company has a good safety and health background,” Campbell says. “If your incident rates are too high, if you’ve had too many accidents, OSHA citations, if you don’t fit their bill, you can’t work on their project, regardless of how good your production quality may be. Fifteen years ago, you would go to interviews and bid jobs and it was all about how much you were charging and when you could have it done. Today, if your safety program’s not strong enough, then you’re not even going to be thought of for a project.”

Campbell also notes that safety programs also promote savings when it comes

to employee retention.

“Ever since 2002 when I’ve been here, I’ve seen a big shift in people,” he says. “Instead of saying, ‘Oh, here comes the safety person,’ to ‘I like working for a company that puts my safety first.’”

Flipping the Mindset

Granite City, Illinois-based icon Mechanical won the 2024 SMACNA Safety Innovator of the Year award last fall for its creative “Good Catch” program, a safety initiative aimed at mitigating accidents by rewarding employees for catching and reporting hazards.

Icon Mechanical uses Microsoft forms— technology it already had—along with QR codes to empower employees to report safety observations at any moment, fostering a culture where safety is everyone’s responsibility. This initiative simplifies hazard reporting and enables real-time analysis, leading to swift corrective actions and a notable reduction in accidents.

“There are different things employees can report,” explains Joe Shryock, safety director at icon Mechanical. “They can submit a Good Catch from a safety-related standpoint, or they can submit a qualityrelated Good Catch, and we also have a World Class Shout Out option, where they can give recognition to their coworkers. We have a weekly newsletter that goes out and I broadcast those shoutouts company wide.”

To maximize the Good Catch program’s visibility and accessibility, the firm

strategically places QR codes on daily JSAs, TBTs, and other prominent locations throughout its projects.

“We used to have a ‘near miss’ program for years, but it’s always had a very negative feeling to it when you report a near miss,” Shryock says. “People think they were going to get in trouble. They think it’s a bad thing. So, we took that idea, and we reframed it. Every Good Catch that gets reported technically can be reported as a near miss, but we’ve changed the name and the entire mindset around it. Now, we celebrate it. Every time a Good Catch is reported, it’s a good thing.”

icon conducts a bi-weekly prize drawing to promote engagement further and recognize individual contributions, randomly rewarding the “Best Catch” and

other submissions. This boosts morale and underscores our commitment to valuing every submission. Depending on the Good Catch tier (whether it prevented an accident, injury or even death), prizes range from $50 gift certificates to Blackstone grills to $500 Visa gift cards.

Shryock notes that in the last 18 months the program has been active, icon

Mechanical has received about 1,200 Good Catch submissions. “Numbers don’t lie,” he says.

“The end goal is making sure everyone gets home the same way they walk on a job site,” Shryock adds. “We don’t have a safety budget here, yet this program is a good investment. It allows us to be extremely proactive instead of reactive.

The Top 10 OSHA Violations of 2024

The Occupational Safety and Health Administration (OSHA) released its Top 10 most frequently cited workplace safety standards for 2024. This list aggregates the citations issued by OSHA staff for violations of federal standards as they conduct safety inspections of workplaces. OSHA’s Top 10 citations in 2024 consists of safety violations noted during the 2024 fiscal year between Oct. 1, 2023 and Sept. 5, 2024. It should be noted that most categories did see a decrease in the number of citations from 2023 to 2024, and the total amount between all 10 categories decreased by 3,540 citations.

No. 1: Fall Protection—General Requirements

For the 14th year in a row, Fall Protection—General Requirements staked its claim as the most frequently cited workplace safety standard in 2024. However, violations cited in inspections were nearly 1,000 less than in 2023, with 6,307 citations in 2024.

Shryock and his team analyze every Good Catch that comes in, which allows them to see trends developing before anything ever happens. They use that data to drive the topics for the company’s weekly safety talks.

Creating Buy In

P1 won the 2024 Mechanical Contractors’ Association of America (MCAA) Safety Excellence Award for contractors logging over 1 million hours. Through rigorous daily checklists, mental health resources, training, and mentorship, P1 is committed to ensuring its employees show up every day mentally and physically prepared to make the best decisions. The firm has also been developing a second safety orientation to help mitigate injury numbers. All new associates will receive the standard

No. 2: Hazard Communication

With a total of 2,888 citations in 2024 (down from 3,213 in 2023), Hazard Communication came in at the No. 2 spot again this year. Standard 1910.1200 is intended to comprehensively address the issue of classifying the potential hazards of chemicals and communicating information concerning hazards and appropriate protective measures to employees, and to preempt any legislative or regulatory enactments of a state, or political subdivision of a state, pertaining to this subject.

No. 3: Ladders

safety orientation when hired. In 60 days, after getting some on-the-job experience and exposure to P1’s high expectations for safety, they will be re-trained on the same topics they initially learned to ensure they understand, and buy in to, P1 safety standards.

“We looked back five years and analyzed our injuries internally,” Campbell says. “We looked at the tenure of our employees and how long they had been with us before they had an injury—42% were within the first year, and out of that, 31% were within the first five months. So, we looked at our orientation process and decided to start the 60-day reorientation.”

Additionally, all new employees get a red sticker on the hard hat for their first six months on the job, regardless of their age or experience level in the industry. It

Ladders once again claimed position No. 3 based on 2024 OSHA data on workplace safety citations. Like some of the other categories, it, too, saw a bit of a drop in the total number of violations, with 2,573 in 2024 compared to 2,978 in 2023. Standard 1926.1053 provides all general requirements for ladders (including man-made ones). It also offers the designated loads per each type of ladder.

No. 4: Respiratory Protection

Respiratory protection, which was previously at position 7, jumped up to 4, even though the number of violations for it has gone down slightly, from 2,481 citations in 2023 to 2,470 in 2024. Standard 1910.134 deals with breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors.

No. 5: Lockout/Tagout

Moving up one position, Lockout/Tagout had a total of 2,443 citations in 2024. The standard most associated with this category is 1910.147, which covers the servicing and maintenance of machines/equipment in

lets their fellow coworkers know they might not be familiar with P1’s safety culture and to keep an extra eye out.

“That’s how we’ve been successful,” Campbell notes. “We get our employees’ involvement, from start to finish.”

Shryock agrees that it’s important for employees to be part of the entire process, not just the back end or compliance side of it.

“When we were thinking about changing our policy, we pulled all our employees in at the very beginning,” he says. “Even for something as simple as the type of gloves and eye protection we use, we pull them in and get their input and advice. When it comes from them, buying in is much easier because it’s their own brothers and sisters who helped make the decision. They’re more apt to follow it.”

which the unexpected energization or start-up of the machines or equipment (or releases of stored energy) could harm employees.

No. 6: Powered Industrial Trucks

Standard 1910.178 contains safety requirements relating to fire protection, design, maintenance, and use of fork trucks, tractors, platform lift trucks, motorized hand trucks, and other specialized industrial trucks powered by electric motors or internal combustion engines. Dropping one spot to No. 6, Powered Industrial Trucks saw a decrease in the total number of citations between 2023 to 2024, from 2,561 to 2,248, respectively.

Advice for Contracting Firms

Contracting firms should use any and all resources they can, according to Crandol.

“We just had our convention, and there was a small mechanical firm with only 50 total employees—that’s in the office and the field,” he says. “He’s not the smallest of our members, but he is a smaller contractor versus a company with thousands of employees. He doesn’t have a safety department, but he does have an association chapter executive and an insurance broker. SMACNA has some basic written programs to help contractors get started, and they can build and grow from there.”

Shryock notes the most important thing is to remember a safety program is primarily for your people.

No. 7: Fall Protection—Training Requirements

Standard 1926.503 states that employers shall provide a training program for each employee who might be exposed to fall hazards. In 2024, there were 2,050 violations.

No. 8: Scaffolding

Scaffolding, previously ranked at No. 4 with 2,859 violations, has fallen to No. 8 with 1,873 violations.

Standard 1926.451 states that each scaffold and scaffold component shall be capable of supporting, without failure, its own weight and at least 4 times the maximum intended load applied or transmitted to it.

No. 9: Personal Protective and Lifesaving Equipment—Eye and Face Protection

Standard 1926.102 states employers shall ensure that each affected employee uses appropriate eye or face protection when exposed to eye or face hazards. There were 1,814 violations in 2024.

No. 10: Machine Guarding

Standard 1910.212 requires that one or more methods of machine guarding shall be provided to protect the operator and other employees in the machine area from hazards, such as those created by point of operation, ingoing nip points, rotating parts, flying chips, and sparks. This category had a total of 1,541 violations in 2024.

your employees in the process and make sure they know you care about them. Be transparent, be consistent, communicate, but involve them. Having them be part of the decision-making process, whether it’s safety related or not, is key.”

Campbell agrees that a company’s most valuable asset is its people. “The biggest thing that’s going to get buy in is proving you care about your employees. You have to prove that you truly want your employees to go home the same way they came to work.”

“Our people are our most important asset, and they should be treated as such,” he says. “Every action and decision we make at icon has that in mind. Mental health has been a big push for us lately, too, especially in construction. Having a robust employee assistance program is another way to improve your safety culture. Involve

His advice to other firms is to be cautious about what they implement. “Just because it works for one company doesn’t mean it’s going to work for your company. Really look into why they’re doing it and if it will work with your people. You have to make it fit your business and your people.”

Evaluating and Solving Common Cooler and Freezer Problems

Preventative maintenance and efficient troubleshooting of commercial refrigeration systems helps reduce service calls and maintain equipment efficiency. By Chris Thomas

For service technicians in the field, no two service calls are exactly alike. Refrigeration issues often stem from a combination of causes rather than a single, clear-cut failure. Temperature fluctuations, ice buildup, compressor malfunctions, and water leaks are among the most common problems found in commercial coolers and freezers. Knowing how to identify and resolve these issues quickly can prevent costly downtime, reduce energy consumption, and extend equipment life.

Refrigeration Red Flags

One of the most frequent complaints from operators is inconsistent temperature control. When a cooler or freezer struggles to maintain proper temperatures, the root cause often can be traced to a mis-calibrated thermostat, restricted airflow, or door seals that no longer hold a proper seal.

Overloaded shelves and blocked evaporator fans can severely disrupt airflow, causing some areas to become too warm while others drop below the setpoint. Ice-covered evaporator coils present another common culprit, leading to inefficient heat exchange

and erratic temperature readings.

In these cases, technicians should verify that the thermostat is functioning correctly before addressing airflow restrictions and potential coil icing. Regularly inspecting and replacing worn door gaskets can prevent warm air from infiltrating the system and throwing off temperature consistency.

Excessive frost or ice buildup is another red flag that often points to humidity issues or a failing defrost cycle. Frequent door openings allow moisture-laden air to enter the unit, leading to frost accumulation on the evaporator. If left unchecked, this can result in ice blockages that restrict airflow and force the compressor to work harder than necessary. Malfunctioning defrost cycles exacerbate the problem, as ice buildup that isn’t properly melted during the defrost phase can eventually lead to frozen coils.

If ice accumulation is severe, check the defrost timer, heaters, and termination switch to determine if the system is operating as intended. Additionally, inspect the door seals for leaks, as damaged gaskets can allow warm, humid air to enter and contribute to frost formation.

Heatcraft Refrigeration Products

Compressor failures are another frequent issue, often stemming from poor maintenance or electrical problems. When diagnosing compressor issues, a thorough inspection of the refrigeration system is necessary to pinpoint the root cause. Cleaning condenser coils, verifying proper refrigerant charge, and checking electrical components can help restore compressor function and prevent further damage.

Excessive moisture in a refrigerated space can stem from multiple sources. Improper defrost settings may cause residual water on the coil to steam, leading to condensation on walls, ceilings, and floors. Water leaks inside or around the refrigeration unit often indicate clogged or frozen drain lines. Flush drain lines regularly to prevent blockages from debris or ice buildup. Excessive condensation on doors and gaskets suggests warm air infiltration due to poorly sealed doors or improperly sealed barometric dampers, allowing warm, humid air to enter the box. Check gasket integrity, hinge alignment, and damper function to ensure a proper seal.

Unusual noises from a refrigeration system often serve as early warning signs of mechanical wear or refrigerant issues. Rattling and grinding sounds may indicate failing fan motors or worn compressor bearings, while hissing noises can suggest refrigerant leaks or restrictions. Identifying and addressing these problems early can prevent more serious damage down the line.

A refrigeration system that runs inefficiently will draw more power than necessary, driving up energy costs while putting

excessive strain on its components. Regularly clean the evaporator and condenser coils, replace worn door seals, and optimize temperature setpoints based on product load to improve efficiency and lower operating costs.

Preventing Problems Before They Start

The key to preventing costly breakdowns is a strong preventative maintenance program. Routine inspections of critical components—such as coils, fans, door seals, and drain lines—can help identify potential failures before they escalate. Adhere to cleaning schedules to remove dust, grease, and ice accumulation that can compromise efficiency. Monitor performance trends, including temperature fluctuations and defrost cycle effectiveness, to spot inconsistencies and address them proactively. Additionally, check electrical connections, relays, and contactors for signs of wear to help prevent sudden system failures.

Ultimately, keeping commercial coolers and freezers in top condition requires a combination of regular maintenance and prompt troubleshooting. By addressing small problems before they turn into major failures, technicians can help businesses maintain efficient refrigeration systems, reduce service calls, and extend equipment life. In an industry where uptime is critical, staying ahead of potential failures can make all the difference. Chris Thomas is the supervisor of product services at Heatcraft Refrigeration Products.

When homeowners find the information they need, fast and upfront, they’re more likely to follow through.

The Amazon Effect: Why Contractors Should Embrace New Technologies as On-Demand Expectations Grow

Picture this: It’s 10 p.m. A homeowner, phone in one hand, remote in the other, starts Googling HVAC installers and flipping through reviews, while half-watching a Netflix show. They’re not calling anyone. They’re not leaving voicemails. They’re scrolling, clicking, and making decisions—right there, pajama-clad, on their couch.

That’s the Amazon Effect. It’s not about sameday shipping anymore—it’s about how we expect everything, from new sneakers to a new furnace, to feel that seamless. For contractors, that shift isn’t a threat. It’s an open invitation.

Digital Curiosity Meets Home Services

Homeowners aren’t just dipping their toes into digital—they’re swimming laps. Recent surveys show 70% of customers prefer booking appointments online, and a striking 94% would switch to a competitor if online booking were available.

Buyers across industries are completing 70% of their decision-making journey before they ever talk to a salesperson.

And you can bet that the same thing is happening in home services. That means your website is no longer just an afterthought—it’s your silent closer.

Why They Click (or Don’t)

Think about how people choose a trusted mechanic or electrician. It’s not about finding the cheapest option—it’s about who clearly lays out services, pricing expectations, and makes it simple to get started. Even a great provider can get overlooked if the basics—what you offer, how to schedule, what to expect—aren’t front and center.

Homeowners do the same when checking out contractors. They’re not necessarily shopping for the lowest price; they’re looking for professionals who will do the job right and make it easy to understand the next steps. Sharing a price range doesn’t lock you in—it simply helps homeowners set realistic expectations, so when you show up, the conversation starts on the right foot.

And the data backs it up. 80% of U.S. consumers search online for local businesses weekly, and 70% are more likely to choose contractors with online pricing. It’s not about racing to the bottom—it’s about showing you’re easy to work with from the first click. Transparent, easily accessible information wins attention and trust.

Let Simplicity Do the Heavy Lifting

Think of Amazon’s model: every product page lays out the essentials—pricing, reviews, shipping times—so customers can make a decision without second-guessing.

Home services don’t need to reinvent the wheel. The same principle applies: offer a clear, straightforward online experience. Give homeowners the ability to schedule appointments on their terms. Cut out the friction of phone tag and endless back-and-forths. Provide a price or a range upfront, and explain what factors might push costs up or down.

It’s not about racing to be the cheapest. It’s about showing you’re easy to work with. And the payoff?

Transparency drives loyalty. 94% of consumers say they’re more likely to support brands that are transparent, and brands that prioritize transparency see 25% higher customer loyalty over time.

When homeowners find the information they need—fast and upfront—they’re more likely to follow through.

AI Isn’t Replacing You—It’s Backing You Up

AI doesn’t change how you do the job—it clears your plate so you can do more of it.

Every contractor juggles a hundred moving parts daily. AI tools handle the routine stuff: auto-confirming appointments, rerouting techs when jobs run long, logging repeat service calls without eating up your admin’s afternoon.

The result? Studies show AI boosts team productivity by 15%, especially helping newer employees ramp faster. Even better, 80% of employees say AI improves the quality of their work by cutting out repetitive tasks.

It’s not about replacing people—it’s about giving them fewer fires to put out and more room to focus where it counts.

Where Clicks Turn into Contracts

Here’s the payoff: Homeowners aren’t avoiding human interaction. They’re doing homework. By the time you show up at their door, they’ve seen your site, checked your reviews, and maybe even booked the appointment themselves.

That’s not cutting out the conversation—it’s earning the right one.

Each online touchpoint becomes an on-ramp: clean website, clear info, simple booking, fast responses, online pricing. Stack those together, and you’ve built trust before a word is spoken.

Less Friction, More Focus

The Amazon Effect doesn’t mean everyone wants HVAC to feel like online shopping. It means they want the hassle stripped out. The process—quote to install—shouldn’t feel like decoding a puzzle. They’re not here to change how you run your business—they’re here to make sure more homeowners can experience it. They’re about giving homeowners the autonomy they want and giving contractors more breathing room to do what they do best. No gimmicks, no fearmongering. Just fewer hurdles for you and your customers.

Breaking Down Silos

One of the biggest mistakes contractors make, especially when they’re in growth mode, is treating each part of the business like it lives in its own bubble. Marketing is in one corner. Operations in another. Sales on their own island. Finance as an afterthought. Leadership gets stuck in firefighting mode, and, before long, you’ve got a disconnected team wondering why the momentum has stalled. But the truth is, nothing in your company operates independently. Every piece is tied to another. If you want to build something that is capable of scale, you must stop thinking in silos and start building systems that connect.

know exactly how to knock, what to say, where to stand, and how to introduce themselves. This needs to be standardized! We created a simple home entry process that each tech is trained to follow, and it is aimed to instantly build trust.

4. Get Sales, Ops, and Marketing in the Same Room Weekly

This one’s huge. Create a shared scoreboard that informs the whole team how we win. Let each team see what the other is dealing with. Transparency breaks barriers.

Great marketing without great operations is just an expensive way to make a bad first impression.

Everything from your finances to your dispatch board to the way a tech knocks on the customer’s door—it’s all part of the same story. At Yarbrough & Sons, we’ve learned that great marketing without great operations is just an expensive way to make a bad first impression. And great service with poor marketing is like having the best-kept secret in town that no one knows how to call. A customer’s experience doesn’t start when your tech pulls into the driveway. It starts with the first click on your website, the first ring on your phone, or the first ad they saw online. Every one of those interactions must match the next.

That only happens when everyone is aligned. It all works together. If you want to grow, the entire machine necessitates clarity, consistency, and culture. Here are 7 takeaways any contractor can implement to eliminate silos and build a tighter, more scalable business.

1. Train Your CSRs Like They’re in Sales

They’re not just answering phones. They’re setting the tone for the entire customer experience. A welltrained CSR can either win or lose a job in under two minutes. That’s not pressure, it’s power. Equip them with scripts, teach them how to listen, and make sure they understand the impact they have.

2. Market What You Actually Do

If your ads promise Ritz-Carlton but your tech shows up looking like (s)he just left a Toby Keith concert, you’ve got a brand problem. Be authentic. Your marketing should preview the experience your team delivers. That’s where trust begins.

3. Standardize the Home Entry Process

First impressions aren’t negotiable. Your tech should

5. Make the Office Feel Like a Command Center, Not a Call Center

Your communications team isn’t just “answering phones.” They’re coordinating experiences. They’re the connective tissue between customers and the field.

6. Price Transparently and Communicate It Consistently

Confusion kills trust. Whether it’s a dispatch fee, a repair estimate, or a system replacement, the customer should understand the price, the value, and the why. No surprises. No pressure. Just clarity. We have taken it a step further and allow each person on our team the freedom to offer a price breakdown for the service they are providing. This drives the trust we are looking for. That’s how you build customers for life.

7. Build a Culture That Doesn’t Blame, It Builds “We before me. No ‘I’ in team.” And other coachisms… When something breaks down, don’t point fingers. Ask where the system failed. Growth happens when teams take ownership, and leadership takes responsibility for the systems that support them. Create a culture where mistakes become momentum, and errors aren’t viewed as a character flaw; rather, they are a learning opportunity.

At Yarbrough & Sons, we’ve worked hard to make sure every part of the company feeds the next. From the first call to the final invoice, it’s all connected. Every day is game day, so we act like it. You must build systems that don’t rely on heroics. Success is mundane; it is found in the duplicity of our processes and in the ordinary, everyday success of your team. There’s no magic bullet, just alignment. There cannot be silos in a business that grows.

We often think mentorship is reserved for elite relationships or formal settings, but that’s not the case anymore.

Redefining the Concept of Mentorship

How many times have you been told that one of the fastest ways to success is finding the right mentors? For years, that single piece of advice overwhelmed me.

As someone with big goals living in a small town, the idea of finding a mentor who could meet with me regularly felt impossible. I imagined mentorship as this formal relationship—coffee meetings, scheduled phone calls, someone taking me under their wing. And because I couldn’t figure out how to make that happen, I told myself I didn’t have a mentor. Sound familiar?

If you’ve ever felt the same way, let me tell you this: you’re not alone. And more importantly, you’ve likely had mentors all along. You just didn’t know it. It wasn’t until about a year ago that everything shifted. I was aimlessly scrolling social media and came across a video from a woman I look up to and

admire. In that video, she said something that changed the way I view mentorship forever: “Most of my mentors don’t even know I exist.”

She went on to explain that mentorship today doesn’t always come from a one-on-one relationship. In today’s world, we have access to some of the smartest, most inspiring people through podcasts, books, webinars, and social platforms. She had been learning from leaders for years, just by listening, reading, and observing. That was her version of mentorship.

1. Are they living a life I want to live? If someone’s work, values, and lifestyle don’t align with what you want, they’re not the right guide—no matter how successful they may appear.

2. Are they actively helping others succeed? Look for people who share what they know—whether through speaking, writing, or teaching. You can’t learn from someone who keeps it all to themselves.

Once I had a list of potential mentors—from industry leaders to motivational speakers—I started studying them. I know that word can sound strange in this context, but it’s exactly what I did. I paid attention to the details:

• What’s their daily routine?

• Who are they spending time with?

• What are their habits?

• How do they handle challenges?

• What books or tools do they recommend?

• How are they pouring into others?

Mentorship isn’t about copying someone’s life—it’s about identifying the behaviors, mindsets, and systems that make them effective, and adapting them to your own journey.

And here’s the part that matters most: you have to do the work. You can’t just follow, watch, or listen—you have to act on what you’re learning. That’s where real transformation happens.

In the trades industry, especially, this kind of mentorship can be powerful. Maybe there’s a contractor whose leadership style you admire. A business coach who breaks things down in a way that makes sense. A company culture you’d love to replicate. You don’t need an invitation to start learning from them. You just need to start paying attention—and then taking action.

Over time, you’ll start to notice something amazing: as you implement these new habits and perspectives, you’ll grow. Your team will grow. Your business will grow. You’ll begin attracting people who want to learn from you. And that’s when you realize—you’ve become a mentor yourself.

That simple idea unlocked something in me. It might seem like a “well, duh” moment for some, but for me, it opened a door I didn’t even know existed. I realized I’d been mentored by countless people over the years. I just hadn’t been intentional about it—until now.

Once I accepted that my mentors didn’t need to know me personally, I got strategic. I asked myself two key questions:

We often think mentorship is reserved for elite relationships or formal settings, but that’s not the case anymore. Mentorship today is accessible. It’s practical. And most importantly, it’s powerful when you treat it with intention.

So, whether you’re a new business owner in the trades or a seasoned pro trying to reach that next level, stop waiting for a mentor to show up. Choose them. Learn from them. Take what they teach and put it to work.

Success leaves clues. It’s your job to follow them.
