Stack Heating & Cooling
live in the Midwest—Michigan to be exact (Go Lions!). This summer has been one of the hottest, muggiest summers I can remember in recent times. And I know I’m not alone. According to the Associated Press, summer 2025 has had dew points that average 6 degrees higher than normal (compared to 1951-2020) in Washington, Baltimore, Pittsburgh, Richmond, Columbus, and St. Louis. Combine that with the wildfire smoke from Canada causing air quality issues, and I feel like we’ve barely left the comforts of indoor climate control to enjoy the great outdoors.
While frustrating for the average person, the hot weather is usually a good sign for HVAC contracting businesses. Last month, Rogers Heating, Cooling & Electrical VP Alyssa Rogers wrote a great column on how she stopped letting the chaos of summer break her business. In it, she shares five best practices for businesses to adopt to prepare for the busy season. One of them is “support your team when it’s hardest.”
It may seem like a no-brainer, but I guarantee some companies don’t think about this concept. According to a Gallup poll, 76% of employees experience burnout on the job at least sometimes, and 28% say they are burned out “very often” or “always” at work.
While studies have shown that burnout risks increase significantly as the number of hours worked each week increases, Gallup’s study indicated other factors contribute to burnout, including unfair treatment at work, unmanageable workload,
unclear communication from managers, lack of manager support, and unreasonable time pressure.
For HVAC contractors, long hours, emergency calls, extreme heat, and high customer expectations can quickly wear down technicians, leading to mistakes, reduced productivity, and increased turnover. This not only drives up costs in recruiting and training but also risks damaging customer satisfaction and the company’s reputation.
With the shoulder season just getting started in the Northern states, now is a great time to examine your processes and procedures. Are you or your management team regularly meeting with employees to listen to any concerns or suggestions for improvement? Do you send out an employee satisfaction survey? Are you rewarding high achievers? Even a simple “thank you” to employees after a long, hard day will go a long way.
Fostering open communication and recognizing employee achievements creates a supportive culture where team members feel valued, reducing stress and keeping morale high.
In the end, preventing burnout isn’t just about protecting employees—it’s about protecting the business. High morale and a positive company culture lead to stronger retention, better performance, and happier customers. By prioritizing the well-being of your team, you can build a more resilient business that can successfully weather busy seasons, deliver consistently excellent service, and stand out as the HVAC contractor (and employer) of choice in a competitive industry.

SEATTLE—EDEN, a digital sales enablement platform in the home services industry, announced a new solution for HVAC field technicians to convert routine service calls into full unit replacements, ramping up lead generation and avoiding missed sales opportunities.
EDEN’s new Instant Quote feature is available to technicians in two different ways—as a unique NFC card that techs can carry with them or as a mobile wallet QR code that techs can store on their Apple or Android devices. Both technologies work in much the same way, providing a straightforward, lowpressure way to provide replacement solutions to homeowners. Even when a system isn’t due for immediate replacement, this approach helps build trust and plant the seed for future upgrades— allowing technicians to stay focused on service while still opening the door to future sales.
The EDEN Instant Quote experience is customized to match the HVAC company’s colors, logos, and other branding elements, ensuring a fully professional customer-facing brand and message.
“What we’re most excited about with the new Instant Quote technology is the introduction of individualized tracking,” said Josh Koplin, co-founder of EDEN. “HVAC service companies will now be able to attribute replacements to specific technicians. When paired with compensation strategies, it can be a powerful way to incentivize field techs to share upfront pricing information with homeowners.
“We think of this as a new channel for lead generation—an easy, transparent way for technicians to introduce conversations about new systems and pricing, and to support a better homeowner experience,” Koplin added.

With over $3 million in savings and a 30% reduction in carbon footprint, North Shore’s pioneering geothermal system exemplifies how schools can adopt cutting-edge green energy solutions to benefit both the environment and operational budgets.
North Shore School District 112, located in the northern suburbs of Chicago, is making history as the first in the nation to power its schools with a Dynamic Closed Loop (DCL) geothermal system. The groundbreaking installation sets a new standard for energy efficiency in K–12 education—slashing emissions, lowering costs, and redefining what’s possible for sustainable learning environments.
Like many schools in the nation faced with aging infrastructure, North Shore School District 112 was looking for an innovative solution that would not only address immediate needs, but also serve generations of students into the future.
“The inspiration for green energy and saving taxpayer dollars was at the heart of our project,” said Dr. Michael Lubelfeld, superintendent, North Shore School District 112. “Trane’s implementation of the DCL technology aligns perfectly with our strategic agenda and core values of sustaining both education and the environment.”
Unlike traditional geothermal systems, DCL technology harnesses the superior heat transfer properties of flowing water, requiring significantly less physical space and making it ideal for suburban school settings. The DCL system offers a space-saving energy capture field that reduces environmental disruption, aligning with modern sustainability goals.
“DCL relies on an aquifer for its heat absorption and rejection, and aquifers may exist at desired flow rates at varying depths based on the proposed location,” explained Andy O’Fallon, turnkey project developer at Trane. “This system uses 3 DCL wells. If aquifer flow rates meet the ideal predicted design, it’s possible to produce approximately 75 tons maximum of cooling (heat rejection) and 25 tons maximum of heating (heat absorption) per well at full capacity. A similar traditional geothermal system may need 50 traditional geothermal wells to meet the same capacity. This site did not have the land area to accommodate the traditional geothermal option.”
O’Fallon noted that the building’s Trane water-source heat pump HVAC system was already designed to accommodate a future geothermal energy source. In this design, each zone of the building can independently heat or cool using its own small refrigeration systems which, in turn, heat or cool the glycol loop throughout the building. Once the loop falls below or rises above the operational range, the DCL geothermal can either heat up or cool down the loop, depending on what is needed. The building also has code-required backup boilers to temper the loop during the coldest design days if the geothermal is at capacity.
“The planning process was accelerated due to this building already being under a large-scale renovation, which included Trane’s design and turnkey implementation for a water-source heat pump HVAC system,” O’Fallon said. “The geothermal component, which was originally planned for a future date, was requested by the school district to be completed while the building was already under construction, and Trane agreed to get it done. We engaged a geothermal consultant and
determined that this site was feasible, then proceeded with the design and construction. With a tight timeline, equipment lead times for custom code-required well components and equipment shipped from overseas became a significant challenge. This, in addition to performing the drilling at this site while other trades were finishing their work created some complex scheduling challenges.”
O’Fallon added that the natural geology of a site greatly determines how fast drilling can occur—even between wells drilled in the same area. “[On this site] some wells had more dense rock and slowed the drilling process, while other areas were more porous, and the drilling went faster.”
Due to the site location being in the middle of a suburban neighborhood, O’Fallon noted that a lot of attention was given to the control of water and cuttings produced by the drilling process. “Pits had to be dug, and fluid directed by trenching to a designated area where it could evaporate naturally or be pumped out. This mixture of primarily water and powdered rock is naturally non-toxic; however, it can create pooling and mud if not managed properly.”
The innovative approach, combined with strategic use of federal, state, and local incentives, made the DCL system a financially viable option for the school district. North Shore School District 112 realized over $3 million in savings on a $6.67 million HVAC investment—a return of as much as 50%.
“This project is potentially transformative for educational markets nationwide,” said Patrick Heneberry, Trane Services account executive. “When you combine the various available incentives with Trane’s experience in sustainable systems and our consultative approach, we’re the ideal choice for innovative educational institutions.”
O’Fallon added that the North Shore School District 112 system could be easily scaled to accommodate a single building or a campus of buildings, given the appropriate hydrogeological conditions. “The main consideration for a building owner is if their HVAC system is designed for the use of a water or glycol loop for heat absorption and rejection.”
The Chicago DCL system is expected to reduce the district’s carbon footprint by approximately 30% while providing more consistent and comfortable learning environments. With the potential to offer school districts significant annual savings through reduced energy consumption and lower maintenance costs, the DCL system offers a compelling ROI and a clear path to a more sustainable future.
“Being among the first school districts in Illinois to have geothermal and the first in the United States to install the DCL technology is exactly what we want for our schools, students, and community,” said Dr. Monica Schroeder, deputy superintendent, North Shore School District 112. “This pioneering project serves as a model for other K-12 schools nationwide seeking to reduce their carbon footprint and lower operating costs. The project is a testament to how innovative technology can be leveraged to meet both educational and environmental objectives.”
Proper hydronic heating maintenance goes beyond just adjusting the thermostat; it involves managing the water chemistry flowing through the pipes to protect boilers, pumps, and heat exchangers.
Summer and early fall offer heating contractors an opportunity to enhance their business and reputation. While homeowners enjoy warm-weather activities, this season should also be a prime time for maintenance and customer engagement. Successful businesses focus on delivering consistent product and service quality, emphasizing customer satisfaction through proactive problem prevention. This makes these seasons the perfect time for annual maintenance checks on hydronic heating systems before winter returns.
Even if customers prefer to ignore their heating systems during the warmer months, a unique maintenance program that highlights water quality could capture their interest.
When new water is introduced into a system, either during installation, leaks, or repairs, it brings minerals and oxygen. Over time, that can lead to internal corrosion, mineral scaling, and sludge buildup. Hydronic heating systems corrode without proper maintenance and become less efficient, leading to additional service calls and a shorter lifespan. Replacing a heating system can be very expensive, costing home and building owners thousands of dollars.
Maintaining proper pH levels is key. Most metals in these systems—copper, cast iron, and steel—perform best with a higher pH (around 9-10). If the system includes aluminum components, you must maintain a lower pH, usually between 7.0 and 8.5.
A corrosion inhibitor will help increase pH levels and reduce wear on internal components. Some inhibitors are suitable for all metals, including aluminum, cast iron, and stainless steel.
An annual pH test is a bare minimum. In commercial applications or older systems, checking pH twice a year is a smart move that can help you catch problems before they start.
Start with a visual reading by opening the drain valve and bleeding off some liquid. If it appears clear, proceed with a pH test. To run a pH test, you can use test strips that provide a color-coded readout. If you need a more precise reading, say, for an aluminum system, use a digital pH meter.
Levels of freeze protection and corrosion protection should also be checked annually. Use test strips to check overall protection, including the levels of propylene glycol and corrosion protection.
Steam systems come with their own set of challenges. Even in a well-functioning setup, you’ll lose some water through steam. That means you’re constantly introducing fresh water, and with it, more minerals and oxygen. If those elements aren’t treated, corrosion and sludge can build up fast.
Left: Hydronic heating systems corrode without proper maintenance and become less efficient, leading to additional service calls and a shorter life span.
Below: Sludge often points to corrosion in the heat exchanger, fittings, or piping. It’s also advisable to add a corrosion inhibitor once a year to help condition new water entering the system.
As a steam boiler heats up, water becomes steam flowing through the system. When that steam condenses, it will return to the boiler. Newer, more compact boilers don’t have the same capacity as their older counterparts, leading to quicker water depletion.
To address this issue, oftentimes a reservoir tank is installed along with components that sense when the boiler water levels are low or completely depleted. These components automatically shut the boiler down, allowing water to return to the boiler or reservoir tank giving it time to refill. Essentially, they prevent the unit from firing if there’s insufficient water.
Timers on these systems indicate a shutoff for a set period, usually one to three minutes, to allow all condensate and water to return to the boiler. If the return water is insufficient, electronic and solenoid valves will open to let more water in, introducing oxygenated water that can lead to corrosion or a pump will deliver water to the boiler
from the reservoir tank. This is why it’s critical to flush these safety components periodically to mitigate mineral buildup.
Oatey recommends using a cleaner, especially if the system isn’t dirty enough to warrant a complete flush. These cleaners are designed for cleaning and conditioning steam and hot-water boilers in hydronic heating systems while containing silicone that protects pumps by lubricating seals, maximizing efficiency, and preventing valve clogging and corrosion.
Always monitor your system’s pH levels. If the first liquid sample in your visual pH reading shows significant rust or sludge, it may require a more aggressive approach, such as flushing with a system restorer.
Sludge often points to corrosion in the heat exchanger, fittings, or piping. It’s also advisable to add a corrosion inhibitor once a year to help condition new water entering the system.
Regular maintenance, including the use of cleaners or corrosion inhibitors at least once a year—typically at the beginning or end of the heating season—is crucial for the longevity and efficiency of steam boilers.
Newer residential hydronic systems are typically designed as closed-loop systems. It’s important to avoid opening and flushing a closed-loop system unless absolutely necessary. The reason for this caution is that the primary enemy of such systems is oxygenated water, which can lead to corrosion and other issues.
However, like a car, closed-loop hydronic heating systems require regular servicing to prevent problems and maintain efficiency. Subtle clues that a system might be experiencing issues include a rumbling noise indicating that minerals are starting to collect within the system. Even in a closed loop, a component remains that feeds water into the system as needed.
Additionally, your customer might unknowingly have a system leak that automatically introduces oxygenated water over time from a pressure regulating valve. This can create numerous complications and alter the pH level within the system, contributing to corrosion.
For a closed-loop residential boiler to function effectively, the circulating liquid must maintain the appropriate pH levels. A yearly pH test is recommended to identify potential leaks or sludge buildup and
determine if the system requires flushing with a cleaner.
Discolored water isn’t always a sign of trouble. In fact, slightly brown water is normal in systems with cast iron or copper components. But sludge is another story. Sludge forms when metals corrode or minerals settle at low points in the system, typically the boiler or heat exchanger. Left unchecked, sludge buildup can impair heat transfer, block drain valves, and even push cast iron boiler sections apart. That’s why corrosion inhibitors matter. They don’t just prevent damage; they help keep the system clean and efficient in the long term.
Modern systems often include air separators and debris filters that help trap particulates before they cause damage. If your system has one, make sure it’s being cleaned at least once a year.
Whether you’re maintaining a single-family boiler or a system in a multi-unit building, an annual service checklist should go well beyond a quick visual once-over.
Here’s a rundown of what a complete inspection should include:
• Visual inspection: Look for signs of leaks, staining, or old corrosion. Check joints, pipes and the boiler body;
• Burner service:Remove and clean burners. Check and replace thermocouples or thermopiles, if needed;
• Sensor checks: Inspect ignition, flame, and water level sensors;
• Exhaust piping: Look for rust on galvanized venting or cracks in PVC piping, depending on system type;
• Control system test:Inspect and calibrate aquastats. In commercial setups, check outdoor temperature sensors and high-limit safety controls;
• Pump check: Inspect for leaks or noise. Different pump types wear differently, so know what you’re looking for; and
• Water quality test: Use test strips or a digital tool to check pH levels and, if antifreeze is present, glycol concentration.
Don’t forget to check any drain valves
or low-point filters, particularly in older systems. These can clog with sediment and make flushing a major headache later on.
When antifreeze is needed, especially in snow-melt systems or properties prone to freezing, choosing the right type and concentration is critical.
Antifreeze does more than just protect against freezing temperatures. A hydronic heating system must also maintain chemical balance, resist corrosion, transfer heat efficiently, and remain pumpable under extreme conditions. Selecting the right product depends on system metallurgy, desired freeze protection, glycol concentration limits, and local climate.
Be aware of the PG ratio (ratio of propylene glycol to water in the antifreeze solution). This impacts both viscosity and compatibility with manufacturer limits. Many manufacturers limit the total glycol content to minimize strain on the system. It’s important to differentiate the “100” on the label, which does not mean “100% glycol.”
Testing with a refractometer or digital meter ensures proper concentration, especially in older systems or after a partial drain-and-fill. Regular testing is necessary, as antifreeze can degrade over time and lose effectiveness in preventing freeze and corrosion damage.
If you don’t check pH, offer corrosion treatment, or test antifreeze levels as part of standard service, you’re missing an opportunity to earn additional revenue and show customers you’re thinking ahead.
The products are affordable, easy to apply, and offer real value. Even if the system is running fine today, protecting it from long-term wear and chemical imbalance can make all the difference in long-term performance, efficiency, and lifespan.
Bottom line: Preventive maintenance isn’t just about checking boxes; it’s about understanding what’s happening inside the system and taking the right steps to keep it running clean. Start with water quality, don’t skip the chemistry, and give every system the attention it deserves.

A2L low global warming potential (GWP) refrigerants are here, and that’s changing how to monitor HVAC equipment for potential leaks and how to mitigate them. Contractors will have to change a few things to adapt to the new rules.
Under the U.S. Environmental Protection Agency (EPA) mandates, new HVAC installations and replacements will require equipment that uses low-GWP refrigerants, mostly A2Ls. This creates a new dynamic because A2L refrigerants are moderately flammable. While the ignition risk isn’t great, this is a significant change from previous non-flammable refrigerants, such as R-134a and R-410A. Non-flammable refrigerants have been in use for the past 90 years.
As a result, contractors will have to mitigate potential fire risks and understand what the A2L rules do and do not cover.
will appreciate that ASHRAE 15, in many respects, is quite flexible.
ASHRAE Standard 15 outlines the different mitigation efforts that must be in place to manage possible refrigerant leaks. A2Ls must be significantly concentrated to ignite, and they burn quite slowly, but are flammable nonetheless. The standard is specifically designed to help protect people from the risks posed by A2L refrigerant leaks or ignition. These rules govern where to place HVAC units and where leak detection and mitigation will be necessary.
The guidelines are largely dependent on the unit’s chemical charge and location, stating that the minimum refrigerant charge—under 4 pounds—is always considered safe, and no mitigation or detection is required. If the refrigerant leaked out, it would not be concentrated enough, even in a relatively small space, to pose a fire risk.
Units with A2L charges greater than four pounds must ship with factory-installed refrigerant detectors placed on the evaporator connected to the indoor space. If a leak reaches 25% of the lower flammability concentration limit, the detector raises the alarm, shutting down the cooling and turning on fans to disperse the refrigerant.
Contractors will become quite familiar with the effective dispersal volume calculation (EDVC), which determines the maximum allowable charge for the space(s) in which refrigerant might disperse.
The EDVC is based on the volume of the vulnerable spaces and the circuit with the largest charge. For example, an appliance might have 75 pounds of charge, divided into four circuits. The EDVC would be calculated based on the largest charge, say, 25 pounds. Contractors have a lot of flexibility to subdivide charges and help ensure they are under the dispersal limit. In most cases, allowable EDVC refrigerant charges are high enough for A2Ls that only certain applications will run into that limit, like VRFs, chillers, and large split systems.
Another critical issue, described in the guidelines, is probability. If the HVAC system is deemed high-probability, leaked refrigerant will likely enter an occupied area. Low-probability systems, like chillers, are often located in machinery rooms and would be unlikely to leak into occupied spaces.
When installing a low-probability system in a machinery room, contractors will need to add external detectors to the room. The in-room detection system must provide audible and visual alarms during a leak. In addition, units in a machinery room will need a remote HVAC system shutoff outside the room and automatic electrical disconnection in the event of a leak.
A high-probability system with A2L refrigerant must automatically generate an alarm within 30 seconds of leak detection and begin mitigation within 15 seconds of the alarm. These various mitigation efforts can engage circulation fans, open zone dampers and set them to full airflow, activate mechanical ventilation and safety shutoff valves, and turn off potential ignition sources, including electric resistance heat in ducts. According to ASHRAE Standard 15, none of these systems need to be connected to a fire board.
If everything is arrayed properly, according to the standard, the only negative consequence of a refrigerant leak would be loss of cooling or heating (if the unit is a heat pump) and the fans coming on for a few minutes. Management will also have to call in a technician to repair the leak.
Contractors will appreciate that ASHRAE 15, in many respects, is quite flexible. For example, there are various equipment options. If one system would exceed the lower flammability limit (LFL) during a leak, and require extra mitigation, there are almost certainly

equipment choices that would meet the LFL without the extra work.
Also, the standard describes what a contractor cannot do, but doesn’t say what they can do (that book would be quite lengthy). While it’s not okay to put a continuous refrigerant pipe across a space that’s not being air conditioned, it is acceptable if the pipe is contained within a fire-rated chase. There are always options.
The first EPA deadline for A2Ls, which went into effect on Jan. 1, 2025, encompassed most chillers, packaged units, split systems, window air conditioners, small, variable refrigerant flow (VRF)—less than 65,000 Btu per hour—and other small systems. Starting in January 2026, these changes will affect larger new
and existing VRF systems. VRF systems use refrigerant piping throughout a building. As a result, the system’s design must take into account the amount of refrigerant that could potentially leak into any one space. The new rules reduce the amount of refrigerant allowed in a room by roughly a factor of four compared to non-flammable refrigerants, like R-410A. As a result, when retrofitting existing R-410A or R-22 VRFs, those systems may have to be pulled and redesigned to transition to A2Ls.
However, as previously stated, the standard is flexible. Contractors installing a new VRF system next year can use multiple, smaller circuits. Three VRF condensers, instead of one, can reduce the charge and keep the system LFL-compliant. In addition, some newer systems use water, along with refrigerants, reducing the total amount of refrigerant required by the system and the risk of refrigerant exposure.
While regulatory changes can be difficult to manage at first, over time, they simply become the water in which everyone swims. The most important thing to remember about ASHRAE Standard 15 is that it is generally flexible. There are creative solutions for every problem, and most of them will not be difficult to implement.
Steve Kujak has over 30 years of experience in the development of new refrigerants, lubricants, and HVACR system designs. He is currently an incoming director at large for the ASHRAE Board of Directors and the director of Next Generation Refrigerants Research at Trane Technologies.

While HVAC software won’t solve the labor shortage, it can reduce friciton and improve efficiency while you continue building your workforce.
The HVAC labor shortage isn’t a future problem—it’s already here. With over 480,000 skilled trade jobs currently unfilled in the U.S., HVAC businesses are feeling the impact. And with the industry projected to grow 6% from 20222032, demand for skilled workers is growing faster than supply.
As a result, contractors are responding by investing in both stronger hiring practices as well as better technology to maximize workforce efficiency.
Did you know, the average HVAC tech is over 55 years old? That aging workforce is a major driver of the 42,500 HVACR job openings projected each year—many due to retirements or career changes.
Furthermore, the HVAC labor shortage is getting worse because younger generations are not entering the trades fast enough to replace retirees. Plus, a rising demand from electrification and energy efficiency retrofits are further widening the gap.
Contractors are facing more complex systems that require advanced technical skills. Most HVAC projects these days aren’t just “fix and replace” jobs. Instead, today’s HVAC jobs involve system optimization, retrofits and integration with smart home technology.
Even though retrofitting buildings is expected to create 1.3 million jobs, the HVAC labor shortage presents a huge challenge for the IEA’s net-zero emissions goal for 2050. In fact, 83% of energy efficiency employers are reporting hiring challenges.
While the future might seem bleak, there are ways contracting businesses can attract top talent to help offset the HVAC labor shortage.
It might seem obvious, but many HVAC businesses are raising pay and offering hiring bonuses to attract more talent. In 2025, the average pay increased roughly 3.5% across all HVAC skill levels.
Which means your contracting business must at least meet these pay raise averages to stay competitive and attract great talent.
Forty percent of employee turnover is due to a lack of career development. Likewise, 82% of employees quit if their employer doesn’t offer career pathing.
In addition, 77% of employees feel their employers aren’t offering career development.
Meanwhile, only 30% of employees feel someone at their work encourages career development.
By providing clear career pathing and mentorship opportunities, you can stand out from other HVAC businesses in your area.
Only 2 in 10 employees feel connected to their company’s culture in the U.S.—resulting in a detached team with higher turnover.
A strong company culture simultaneously improves your labor shortage issues while helping your bottom line. Here’s how a strong company culture increases your key performance metrics:
• 50-point increase in employee engagement (over a three-year period);
• 25% workforce growth (over a three-year period);
• 85% net profit increase (over a five-year period); and
• 138% improvement in patronage (over a fiveyear period).
Look at a few simple ways to reinforce your company culture:
• Provide paid time off and sick days;
• Host company events to create a sense of community;
• Recognize and reward employees for accomplishments and milestones; and
• Offer unique perks (e.g., snacks, parental leave, educational assistance, volunteer days, etc.)
When it comes to lessening the impact of the HVAC labor shortage on your business, hiring speed is crucial. By moving candidates quickly through hiring, you reduce the risk of losing candidates to competitors.
Many contractors promote their use of technology (like HVAC software) as a recruiting advantage. Plus, younger technicians want to work for tech-forward companies. In fact, 64% of Gen Z employees view emerging technology positively.
Since the competition is too fierce in the HVACR industry, job boards alone aren’t enough anymore.
To build a talent pipeline beyond job boards, it’s crucial to be proactive. These are a few key effective strategies HVACR businesses are using to combat the labor shortage:
• Local Networking: Build relationships with trade schools, start apprenticeship programs, and engage earlier with young talent; and/or
• Establish Partnerships: Host “Tech Days” or partner with local workforce development programs to get proactive in pipeline building.
Remember, building a pipeline allows your HVACR business to create warm candidates who are ready when you need to scale quickly during the busy season.
The average HVAC technician generates between $200-650 in revenue per service call during peak seasons. And with most HVAC techs getting 10-12 service calls per day during the busy season, you could lose between $2,000-7,800 per day for an unfilled HVAC tech position.
Plus, there are implications for your HVAC business if you take too long to hire:
• Overworked teams lead to burnout, lower morale and higher turnover;
• Service delays lead to angry customers and bad reviews;
• Revenue opportunities are lost when companies can’t meet demand; and
• Competitors with faster hiring processes can poach candidates, new service contracts and even loyal customers.
Contractors who are short-staffed are using technology to maximize efficiency. While HVAC software won’t solve the labor shortage, it can reduce friction and improve efficiency while you continue building your workforce.
Here are five ways successful HVAC businesses use software to stay efficient and meet demand:
• Easy Dispatching: Quickly assign techs to the right jobs based on their skillset and job location. Drag-and-drop scheduling features help reduce delays and boost job accuracy.
• Accounting Integration: Modern HVAC platforms often sync directly with accounting software, allowing seamless updates across field and office in real time—no duplicate entry required.
• Customer Management: Access full customer histories, service agreements, quotes, and equipment records in one place, so your techs can deliver consistent, highquality service on every visit.
• Anywhere Invoicing: Enable techs to update invoices in the field, email them to customers, and accept payments on the spot—helping you reduce billing cycles and improve cash flow.
• Mobile App: Empowering techs to view work orders, complete forms, add job notes, and upload photos—all while on-site. This improves communication, accountability, and customer satisfaction.
Contractors who act now—by investing in their employer brand, hiring strategies, and technology—will be best positioned to succeed. The labor shortage isn’t temporary—it’s the new reality— businesses that can adapt to the HVACR hiring shortage will dominate in 2025 and beyond.

In an increasingly competitive and costly environment, contractors face a growing demand to meet strict financial thresholds just to bid on projects, even smaller ones.
Contracting business owners truly need money to make money by ensuring target margins are met, regardless of the current stage in the overall life cycle. From well-established service providers to startups, the need to prequalify and expand opportunities to achieve growth requires ongoing assessment of financial strategies and planning.
The focus for those in the construction trades should remain on optimizing balance sheets and creating appropriate ratios of liquidity.
However, managing operations and job sites often takes precedence over collecting and developing financial performance metrics and then working to reach levels needed to meet almost any basic RFQ requirements. Focusing on the big picture by assessing financial targets early and often ultimately helps minimize barriers to pursuing needed opportunities to fuel growth. In many cases, businesses can achieve this consistent tracking and streamline operations through automation tools that are built into the platforms and technology they already rely on, especially within commonly used accounting, finance, and payroll software.
All construction businesses should look at creating a dashboard of performance ratios aligned with what banks and bonding companies typically analyze to make decisions about lending opportunities that enable larger operating volume or expansive projects. These collaborative opportunities can provide competitive advantages that increase profitability and business valuations while providing access to higher credit limits with better terms and increased bonding capacity.
Completing a ratio analysis gives business owners information to compare the company’s performance to prior periods (e.g., yearover-year or quarter-over-quarter) and, even more importantly, against their industry.
A few ratios to consider in the management of a construction business include:
• Liquidity ratios: The liquidity ratio will determine a company’s ability to pay short-term debts and operating expenses. Generally, the higher the value of the ratio, the larger the margin of safety the company has to meet short-term operating obligations.
• Current Ratio = Current Assets / Current Liabilities; and
• Quick Ratio = Cash and Accounts Receivable / Current Liabilities.
• Solvency ratios: This ratio shows what percentage of assets belongs to outside creditors and what percentage belongs to owners of the business (owner’s equity). A low ratio is good because it means the company has low leverage and the owner has a lot of equity in the business.
• Debt to Net Worth = Total Liabilities / Net Worth.
• Profitability ratios: These ratios will determine your gross profit margin (operating profit) and overhead analysis. These two ratios are highly useful in performing industry analysis and period-over-period analysis.
• Gross Profit Ratio = (Sales minus Cost of Goods) / Sales;
• SG&A (Overhead) Ratio = SG&A / Sales; and
• Profit Margin = Net Income / Sales.
• Management or cash flow ratios: These ratios will help you understand your cash position, cash flow and management of the company.
• Working Capital = Current Assets - Current Liabilities;
• AR Turnover = Sales / ARs;
• AP Turnover = Cost of Goods / APs;
• Inventory Turnover = Cost of Goods / Inventory; and
• Debt Coverage Ratio = Earnings + Interest Expense + Taxes + Depreciation + Amortization (EBITDA or Cash Flow) / Total Principal and Interest Payments on all Debts.
The above ratios are a good start to a reporting dashboard that can help steer a company toward high performance. A banker, CPA, and trade associations can help with additional ratios and industry analyses to fine-tune a dashboard to meet specific goals and objectives.
Ultimately, most banks will look at some combination of five “C factors” to determine the depth of a financial relationship with a construction business: character, capacity, capital, collateral, and conditions, which are the backbone of every credit decision a lender makes.
In turn, access to credit and capital puts businesses in position to avoid setbacks and maintain preparedness in RFQ processes. However, not all growth can be considered good growth. When considering the overall strategy, consider the following questions related to cash flow:
• Do you have enough capital in your business to sustain a growth trajectory?
• Do you have access to cash to cover five months’ worth (or more) of expenditures before collecting any receivables?
• Does your business have the financial expertise in-house to handle budgeting, forecasting, and analysis?
• Can the company generate the same amount of gross revenue at a higher margin?
• Will doubling the size of your company generate the same amount of gross revenue at a higher margin?
Business owners should take a proactive approach in keeping creditors up to speed on business conditions within the construction industry as well as information regarding historic and current performance ratios and projections. This type of mutual investment in financial viability helps contractors successfully meet the demand for specific thresholds in competitive bidding processes.

We live in a digital world, seemingly dominated by digital marketing, whether fact or fiction doesn’t matter. Public perception is reality. Your website isn’t merely an online address; it’s part of your brand identity, your virtual storefront. The rise of .services domain extensions offers both a unique marketing opportunity, as well as a brand protection play.
The .services domain is a “top-level domain” aka TLD, specifically created for businesses that provide, you guessed it, SERVICES! Think .net for tech-based firms or .org for charities. Unlike a conventional .com, which can be hard to obtain these days, a .services domain immediately says what your company does. It’s clear, direct, and probably still available, unlike its cousin .com in today’s saturated digital space. This is especially true for more generic names with words like “climate,” “temperature,” “quality,” etc. All too often, with more generic names, you’ve had to resort to cryptic abbreviations or long URLs that include clunky extras like “llc.” Until now!
A company named “Castle Plumbing” might have been lucky enough to secure a main website like castleplumbing.com, but they can also register castleplumbing.services to reinforce what they do. It’s memorable. It’s search-friendly. It’s great for marketing campaigns like truck wraps, billboards, print/direct mail, or social media.
One of the biggest advantages of implementing a .services domain is when someone sees a website like milfordac.services or topnotchplumbing.services they immediately know it’s a service provider, not a product store or unrelated entity. This extra level of specificity can increase trust, which is one of the Big-3 of Success (know, like, and trust). It
can translate into your site standing out in search results and improve click-through rates.
There’s also a local SEO benefit. Search engines are increasingly sensitive to context. Words matter. So, a domain like jaxac.services instantly ties your company to both the service type and location, potentially giving you an advantage when prospects are scanning search results when trying to decide who they’re gonna call.
Even if you’re not ready to take the plunge, remember that an ounce of prevention is worth a pound of cure. Securing your .services now is a smart defensive play. As popularity increases, competitors, domain resellers, or even unrelated businesses could purchase your company name with the .services extension. This could cause customer confusion or worse—loss of customers and/or leads.
Imagine your biggest competitor buying yourcompany.services and using it to siphon off local online traffic or market misleading promotions and offers. It’s a headache that is entirely preventable. Just purchase your relevant domains before they’re gone and it’s too late. It’s a tiny investment that could save you from a BIG branding problem down the road.
In the hyper-competitive home service verticals, like HVAC, plumbing, electrical, garage doors, etc, protecting and expanding your company’s digital footprint is vital. The .services domain offers a modern, innovative way to market your company, increase brand recognition, and block competitors from encroaching on your name itself. Whether you use it or simply hold it as part of your brand assets, now is the time to act before someone else does.
In the hypercompetitive home services verticals, protecting and expanding your company’s digital footprint is vital.

STUTTGART, Germany—The Bosch Group has successfully completed the largest acquisition in its history with the acquisition of the residential and light commercial HVAC business from Johnson Controls and the acquisition of the Johnson ControlsHitachi Air Conditioning joint venture on July 31. The contracts were signed roughly one year ago. The purchase price is $8 billion U.S. dollars and is subject to customary adjustments.
“With the largest acquisition in our company history, we are accelerating our growth, expanding our global footprint, and balancing our business by strengthening our energy and building technology—this makes Bosch more powerful and robust, in line with our corporate strategy 2030,” says Stefan Hartung, chairman of the Bosch board of management.
With the acquisition, the Bosch Home Comfort division almost doubles in size to over 25,000 associates and more than $8.6 billion USD in sales. In the U.S., Bosch will add approximately 3,400 associates and two new manufacturing sites located in Norman, Oklahoma and Wichita, Kansas.
With the new lineup, Home Comfort wants to grow significantly faster than the global HVAC market. According to Bosch estimates, this will increase by up to 5% every year until 2030.
With its expanded product and brand portfolio, Home Comfort wants to better leverage the potential of its strong and established sales channels and boost sales. Integrated purchasing and the joint development of product platforms should also ensure cost savings. It is hoped that initial successes will be seen as early as 2026. The company can rely on strong brands for this: in addition to Bosch and Buderus, these now also include YORK in the USA and
Hitachi in Asia, as well as other strong local brands. The company is acquiring long-term licenses to use the brand names for YORK and Hitachi.
The global production network of Home Comfort will grow from 17 to 33 plants as a result of the acquisition, while the number of development sites is increasing from 14 to 26. The completion of the transaction marks the beginning of the integration of the new units into the Home Comfort division at Bosch. This should be completed by the end of 2027.
MINNEAPOLIS —Daikin Applied announced it has entered into a definitive agreement to acquire DDC Solutions, a San Diego-based developer of ultra-highdensity cooling cabinets and management software for data centers.
The acquisition will expand Daikin Applied’s data center-focused portfolio— adding in-room, rack-level solutions for white space cooling, and underscoring the company’s commitment to providing complete data center cooling solutions.

DDC Solutions offers a patented, selfcontained hybrid cooling system that integrates air and liquid cooling directly within the data center racks. Unlike traditional air-cooled or plenum-based systems, this design contains heat removal within the rack itself, which improves operational efficiency and eliminates the need for costly infrastructure modifications. In addition, the cabinets provide excellent fire and water protection and significantly reduce the data center’s acoustic signature. They also come equipped with data center infrastructure management software for real-time monitoring and automated cooling adjustment on a per cabinet basis.
“The ability to scale quickly across geographies with Daikin’s resources is a game changer”, said Keith Markley, CEO of DDC Solutions. “The global demand for data center solutions is expanding so quickly and being part of Daikin Applied will allow us to respond to this demand at an even greater level of excellence than before.”
After the closing, DDC Solutions will operate as a subsidiary of Daikin Applied with the full DDC Solutions leadership team remaining in their current roles.

Private equity has made contracting businesses more valuable.
Private equity has rushed into the service trades, acquired a number of legendary contracting businesses, and caused no shortage of consternation on industry message boards and forums. Frankly, the private equity land rush is the best thing to happen to the HVAC industry since the 1990s consolidation.
Let me start with a mea culpa. I sold my company to private equity way back in 2017. I’ve experienced the wire transfer and life as an employee in the company I used to own. I know the pros and cons personally. The pros clearly outweigh the cons. Private equity is making a lot of multi-millionaires in the service trades. This is an awesome outcome. Your buddy, your peer, who’s built a pretty good company is able to take a lucrative exit. Moreover, it’s incredibly positive to see outside money pouring into the trades. It’s about time.
Look, you work a lifetime building a business. You’ve worked hard. You’ve put up with all of the nonsense that comes with a contracting business. You’ve had employees cut your heart out for a buck an hour more from a competitor. You’ve had to fret over cash flow during seasonally mild weather. You’ve dealt with a government that overregulates with regularity. If you manage to muddle through all of that and build a profitable business, you deserve a profitable exit. Before private equity, you didn’t have much of one.
Profitable contracting businesses typically sold for four times EBITDA (earnings before interest, taxes, depreciation, and amortization). A company with $8 million in revenue and a 15% net would sell for $4.8 million at a 4X EBITDA multiple. That seems great until you consider 20% capital gains and the 3.8% net investment income tax (i.e., Obamacare). That reduces your take-home to $3.7 million, depending on your state. State capital gains range from 0% to 13.3%. If the latter, your net is $3 million.
to $370,000. Plus, returns can be even higher after earn-outs and equity rolls are factored in.
Private equity has made contracting businesses more valuable. It has given contractors the ability to exit their businesses before they otherwise could and live comfortably on the proceeds of the sale. What about the independent contractors who don’t want to sell? Private equity is helping those businesses, too, simply by the prices they charge. The most common problem in the industry is poor pricing. As a rule, the contractors purchased by private equity tend to price near the top of the market, but many private equity groups push the top higher.
The pricing levels of some of these companies may seem absurd to the average independent contractor. They are not absurd; they are what is apparently possible, especially with attractive financing programs.
Private equity pricing gives other independent contractors the ability to raise their prices while remaining under the top of the market. Independents may not buy as well as private equity groups, but neither do they have to carry the same levels of overhead. Thus, independents can price to deliver better profit margins than they ever dreamed possible. The entire industry can be more prosperous.
A co-founder and former CEO of Service Roundtable, Matt Michel was inducted into the Contracting Business HVAC Hall of Fame in 2015. He is now an author and rancher.
While $3 to $3.7 million still sounds like a lot of money, consider living on the proceeds of the money when invested. Financial advisors typically recommend reinvesting 2.5% to keep up with inflation and taking 4.5%. This gives you $136,000 to $166,000 for living expenses. Gulp! Anyone running an $8 million business is probably paying himself a lot more than that.
All that’s changed with private equity. It’s not unusual for that same company to sell for a 8X to 10X multiple. If we split the difference and use 9X, the net to the contractor from the sale of his business ranges from $6.8 to $8.2 million. That’s a world of difference. Your living expenses range from $306,000
Private equity has also changed the perception of HVAC. For example, a Wall Street Journal article declared HVAC contractors were the new millionaire class due to private equity. The message is that HVAC is a great career choice and more high school graduates are getting the message.
Private equity has brought investment to the industry in other ways. Seeking efficiencies, private equity groups are driving AI development in the industry and causing other entrepreneurs to develop innovative products and services for HVAC.
Even if you never plan on selling, you should love how private equity is making the HVAC industry better and more lucrative for contractors.
