Your guide to eliminating stale air
Unpleasant in any season, stale air can carry odour, feel stuffy, and harbour contaminants
We’ve all experienced stale air after walking into a room that has been closed up for an extended period without circulation of ventilation. However, as well as being unpleasant, stale air can cause issues if not addressed – including mould, mildew and unhealthy air to breathe.
There are various ways to remove stale air and improve indoor air quality.
Introduce ventilation
The simplest way to improve indoor air quality is to open doors and windows to let the air circulate. This moves the stale air – replacing the oxygen and reducing the risk for mould growth by reducing condensation.
Maintaining a clean environment
Typical household furnishings such as lounge chairs, rugs and carpet can harbour chemicals and allergens such as dust mites, some of which can become airborne. Dusting and vacuuming regularly will help to minimise these circulating around the home, especially if a room is closed with stale air.
Operating your heat pump/ air conditioning system
Turning on your air conditioner allows you to control a room’s temperature and assist with humidity levels. Many units offer dry mode function, where the fan operates at a low speed – removing moisture – and also include a filter which captures fine dust, invisible mould spores and harmful microorganisms that can be lingering indoors. However, it’s important to regularly clean these filters and maintain your air conditioning system.

HVAC&R SYSTEMS - PREVENT LOSS OF LIFE
Earthquake Safety
New Zealand experiences between 50 and 80 earthquakes each day, or about 20,000 a year, with between 150 and 200 being large enough to be felt. It’s important to understand how to install HVAC equipment so it is earthquake-safe and compliant with NZS4219
LOSS OF LIFE
NZS4219 specifies that all systems that are not structural components of the building must have restraints that transfer the load to the structure.
RESTRAIN
Restrain all air conditioning units, heat pumps, water heaters, electrical equipment, piping and ducting, pumps, tanks and fans. Ensure it is safe and continues functioning after an earthquake.
IF IN DOUBT, SHOUT OUT!
If in doubt, shout out! If it is heavy or suspended, it should be restrained. If you spot any equipment (not just the items you are installing) that looks poorly restrained, shout out.
WHAT DOES A SAFE INSTALLATION LOOK LIKE?
• Base units, condensers, and fan coils securely bolted to the structure or on approved seismic vibration isolators
• Lateral supports in place at the top or bottom of the unit
• Condensing units that are bottom-heavy are anchored at the bottom (be aware of overturning forces)
• Proprietary system installation instructions are followed (e.g Monkey Toe, Unistrut, Boardwalk)
• Check for sway restraints on suspended equipment
• Roof-mounted equipment? Consider wind loading and weight distribution
• Fan-coils and heat pumps on a wood-framed floor or roof should be directly anchored through the cabinet on a plywood platform or wooden frame support or on approved seismic vibration isolators
CHECK WITH A STRUCTURAL ENGINEER
Check with a structural engineer if in doubt! Especially where lightweight roofing is used or for custom installations.
Do the installations look like they are secure? A visual inspection can be telling.
Do not install condenser units on top of verandas. This is dangerous and contrary to city bylaws.
Do a seismic check now on new and existing installations. Lives depend on it.
Check with your boss, architects, or structural engineers.
CASE STUDY
An inner-city regeneration project
Cuba Street is known for its shopping, coffee culture, culinary delights, art galleries and street performances. Above the street, many offices take advantage of the popular location, including the Greater Wellington Regional Council.
In the latter half of 2020, the council moved into the second and third floors of a newly created open-plan office space – of the city’s largest with an area of 6,000sqm.
The building
Cuba Precinct is the result of a large regeneration project designed to embody the character of Cuba Street and its environs while providing space for ground-floor retail businesses with office and apartment accommodation above. It involved preserving and injecting life into several historic buildings as well as raising new structures above those buildings.
Designed to have a low carbon footprint and exceed the current New Building Standard, the refurbishment of the historic buildings was completed with these guiding principles in mind.
A smart air conditioning choice
The Mitsubishi Electric R32 Hybrid Variable Refrigerant Flow (HVRF) Air Conditioning System was a logical choice for the large open plan office space thanks to its superior safety features, occupier comfort levels,
and lower operating and maintenance costs when compared to traditional systems using R410A refrigerant.
Get to know the Mitsubishi Electric R32 HVRF Air Conditioning System
A focus on water
A significant safety feature is the use of water throughout the pipework in occupied spaces. This means that refrigerant (R32) is only used in the system between the outdoor condensers and the Hybrid Branch Controllers (HBCs) – well away from any occupied spaces. This removes the need for expensive leak detection equipment in occupied spaces, resulting in reduced maintenance costs as there is no requirement for annual leak detection checks.
Unique two-pipe architecture
Multi-layer composite plastic piping can be used to transport water throughout occupied spaces instead of the traditional soldered copper piping used to transport refrigerant. This feature combined with the unique two-pipe Heat Recovery System – rather than a
Jason Mann Photography
conventional four-pipe chiller system – means less piping is installed and none of the extra controls associated with a 4-pipe system are required, amounting to significant installation cost savings.
Modular
and flexible in design
The modular design and small footprint of the HVRF System along with its flexible duct layout allows airflow patterns to be arranged to suit the application, letting building owners manage a phased installation – a plus when it comes to installation budgets and their inevitable variances.
Efficient heating and cooling at the same time
Outdoor units all have simultaneous heating and cooling and heat recovery. Indoor units are concealed within the ceiling space making for unobtrusive air conditioning while preserving the aesthetic of the working space and overall appearance of the room. Quiet operation is another feature of these units.
Year-round occupant comfort
Low noise levels (due to the use of water instead of refrigerant in the terminal fan coils among other noise-reducing features), more stable milder off-coil temperatures, the removal of draught potential from
office spaces, faster defrosts, no critical refrigeration concerns and less risk to the environment and occupants all contribute to a system that provides comfort with simplified maintenance and a significant cut in long-term energy costs.
Using the system’s flexible master and individual remote controls enables efficient and economic management of airflows, heating and air conditioning levels throughout the building.
As well as a master control, individual room units have remote controls of their own.
The
logical, future-proofed solution
The cost of R410A refrigerant continues to rise rapidly as a deterrent to its use in air conditioning systems due to its high GWP (Global Warming Potential). Mitsubishi Electric’s R32 Hybrid VRF System leverages the low GWP of R32 refrigerant (about one-third that of conventional R410A refrigerant), lower refrigerant costs, a small carbon footprint and reduced running costs to provide an efficient system with built-in future-proofing able to provide high comfort levels while complying with environmental legislation – it’s the logical selection.

HFC gases seized in illegal import investigation
A joint operation with the New Zealand Police and New Zealand Customs Service has seen more than $1 million worth of hydrofluorocarbon (HFC) gases seized by the Environmental Protection Authority (EPA)
Synthetic greenhouse gases with a high impact on the climate despite being emitted at relatively low quantities, HFCs can have global warming potentials of up to 14,800 times that of carbon dioxide.
“The EPA is cracking down on operators who import and sell cheap bottles of HFCs without applying for a permit or paying a levy to cover the greenhouse gas emissions of the HFCs,” says the EPA’s Compliance, Monitoring and Enforcement General Manager, Gayle Holmes.
“Illegal importers are undercutting legitimate operators and, in some cases, selling contaminated HFCs that could damage vehicles and equipment.”
In New Zealand, HFCs are controlled under the Ozone Layer Protection Act and the Climate Change Response Act. Since 2020, New Zealand has been phasing down the use of HFCs as part of an international effort expected to avoid 0.5 degrees Celsius of global warming by 2100. “There are rules around HFC imports so New Zealanders can have confidence that we’re reducing the use of these potent greenhouse gases that contribute to
climate change,” says Gayle.
As part of the EPA’s investigation, several search warrants were executed across New Zealand. Three tonnes of HFCs had so far been seized as of December, with the investigation ongoing.
Offences can carry a fine, and in some cases, up to five years’ imprisonment.The EPA encourages anyone being offered bottles of HFCs at significantly lower than market price to contact its investigations team in confidence at investigations@epa.govt.nz.
Anyone importing bulk HFCs needs a permit under the Ozone Layer Protection Act and must be registered as a participant in the Emissions Trading Scheme. Bulk HFCs are containers of new or recycled HFC gas in an unprocessed form, alone or in a mixture.
Permits are not needed to import HFCs in goods, such as HFCs in car air conditioning or in fire extinguishers. Goods containing synthetic greenhouse gases, including HFCs, are subject to a levy under the CCRA.
REFRIGERANTS - BUY FROM SAFE SOURCES
The risk of buying illegal refrigerants
With a growing occurrence of refrigerants being listed for sale online, it’s important to understand the importance of buying from safe sources – and the dangers associated with purchasing from illegal sellers
There are hefty fines and risks to health and safety for installers and users when working with illegally purchased refrigerants.
HEALTH AND SAFETY IMPACT:
Refrigerants fall under ‘dangerous substances’ and need to be handled with care, even more so with the increased use of flammable and high-pressure gases. Refrigerants that do not comply with the gas producers’ specifications or with the content indicated on the cylinders can pose a serious risk for the health and safety of installers and users.
FINANCIAL IMPACT:
High fines or even criminal prosecution can be involved with the illegal sale of refrigerants.
Operational impact: Refrigerants that do not comply with specifications (impurities, contamination with oil and other substances, etc.) can lead to bad performance of equipment, leading to loss of capacity, reduced energy efficiency, higher operational cost, equipment failures and more.
BUSINESS IMPACT:
In turn, this can lead to the deterioration of relationships with customers and reputational damage as a result of equipment issues.
ENVIRONMENTAL IMPACT:
Risks such as refrigerant leakage into the atmosphere increase even further with the use of inadequate cylinders.
Unfortunately, despite the risks, refrigerants have been appearing online.
"The importation of the refrigerant R404a into New Zealand is controlled via the ETS scheme and carbon taxes are applied at the point of sale. All quantities are recorded and monitored through recognised wholesalers and via the ETS scheme. Selling the products outside of regulated arrangements contravenes the regulations above and the Health and Safety at Work Act 2015, and additionally undermines everything this industry works so hard to achieve including the reduction of our national carbon footprint,” says Chris Arvidson, IRHACE Council member.
“I believe our industry takes its responsibility for refrigerants and the damage they do to the atmosphere very seriously and we have, over the last few years, developed training modules with input from Worksafe to provide compliance with New Zealand regulations and legislation.
“We are substantially disheartened when we see individuals blatantly offering these products at substantially reduced prices, indicating that they are not paying carbon taxes in line with the ETS requirements, and offering them to the general public who do not have the training, knowledge or equipment necessary to handle them safely.”
HOW CAN YOU IDENTIFY ILLEGAL REFRIGERANTS?
Under the Health and Safety at Work (Hazardous Substances) Regulations 2017, anybody handling or recovering compressed gases must have had suitable training and hold an Approved Filler Test Certificate. Most refrigerants currently used in New Zealand are classified as compressed gases under the Health and Safety at Work (Hazardous Substances) Regulations 2017. Some refrigerants currently used in New Zealand such as propane and butane are flammable and hazardous substances under the HSNO Act.
Therefore, nearly all users of refrigerants are required by legislation to hold an Approved Filler Test Certificate.
HOW DO I GET AN APPROVED FILLER TEST CERTIFICATE?
RLNZ provides Approved Filler courses for both A1 and A2/A2L refrigerants which is required by the HSNO 2004 Compressed Gas Regulations and is the minimum legal obligation for anyone working with refrigerant. You can obtain a new license or renew your existing license by learning current information for A1 and A2/A2L refrigerants and passing a practical assessment using current materials and fit for purpose technology. Learn more here
ALWAYS PURCHASE REFRIGERANTS FROM REPUTABLE SUPPLIERS
RLNZ recommends only purchasing refrigerants from reputable suppliers such as:
• Refspecs
• Actrol
• Cooling Supplies
• Patton
• Realcold
• Daikin
• A-Gas
Celebrating women in HVAC&R
International Women’s Day (IWD) on March 8 each year is a celebration of women’s achievements worldwide. It’s an event that has been around for over a hundred years – as have many of the issues still impacting women today. This year’s IWD theme is ‘Accelerate Action’.
According to data from the World Economic Forum, at the current rate of progress, it will take until 2158 (which is roughly five generations from now) to reach full gender parity. Focusing on the need to ‘Accelerate Action’ emphasises the importance of taking swift and decisive steps to achieve gender equality. It calls for increased momentum and urgency in addressing the systematic barriers and biases that women face, both in personal and professional spheres.
So, how can you help ‘Accelerate Action’? We asked three women from the HVAC&R sector to share their experience in the industry.
What advice do you have for women starting out in the HVAC sector today?
Pip Strickland: I have been involved in the HVAC&R industry for nearly 15 years now, with the past eight years being part of the fantastic, diverse team at Refspecs. Similar to many individuals, I stumbled into this field
without prior knowledge. It’s an industry that everyone utilises, but it isn’t widely recognised.
Navigating through a predominantly male oriented industry as a woman can pose initial challenges in gaining acceptance and overcoming certain stereotypes. However, like any field, dedication and time investment in learning can outweigh any struggles.
Engaging with other women in our profession, networking, learning and addressing challenges has also proven invaluable.
Lisa Stoneham: It is a great industry if you apply yourself. Don’t be afraid to jump in, ask questions and give things a go. You don’t become a good technician without making mistakes.
Sarah-Jayne Cook: Network, network, network! When I started my career almost 24 years ago, my support network was very much limited to my place of work;
we simply were not blessed with all the fantastic online platforms we have today. While the number of women working in HVAC has remained relatively static, online platforms have brought our communities together allowing us to connect with other women working in our field, amplifying our voices, and growing our collective influence. With our online platforms and subsequent networks, I really feel like I have found my tribe –like-minded women who actively build other women up!
I would recommend joining the International Women in Cooling (INWIC) community through their website, and the Women in Cooling LinkedIn group as a starting point. You never know where these connections may lead you and the breadth of knowledge you will gain from them.
How can others mentor and empower women to succeed in the sector?
Pip Strickland: The refrigeration and HVAC sector boasts numerous successful women, including company owners, engineers and salespeople, whom I greatly admire. For women considering entering this fantastic profession, I recommend attending industry events to connect with the inspiring individuals who contribute to the excellence of our field.
Sarah-Jayne Cook: Just as I have a mentor and sponsor, you too can offer the same for your colleagues and network. It is one thing to walk through the doors of opportunity, but it takes a true leader to hold that door open for those who follow behind. Be humble, acknowledge your privilege and advocate for the rising stars around you.
In practical terms, nominate your up-and-coming talent for projects and promotions, sing their praises where they are due, offer up opportunities to lead or present, and support them fully through the process. Whether you are a mentor or mentee, it takes long-term commitment, listening, sharing your knowledge and experiences, being respectful and ensuring confidentiality on both sides.
Have you had any key mentors in your career? Can you share a little about them and how they’ve guided you?
Lisa Stoneham: I started my refrigeration apprenticeship in early 2012 and have had some great mentors along the way, but it all started with Michael Jowett. I met Michael on the first day of my apprenticeship and he was the main technician I worked with for the first two years of my apprenticeship. My first day was replacing a compressor on a supermarket rack system. Michael took the time to explain everything, the different components, how they worked and made sure I understood what I was doing and why.
I was very fortunate during my apprenticeship and I worked with an amazing team of technicians who were always willing to help and answer questions.
Sarah-Jayne Cook: I have been lucky to have been supported and encouraged by several incredibly inspiring
people throughout my career to date, but the most significant is my current mentor. I like to think our connection was made through a shared passion for cooling and building a better environment for everyone to thrive in. It has never been a formal arrangement, but more a friendship that has grown into mentorship and sponsorship over the last eight years.
Having someone I can confide in and seek advice and guidance from has been pivotal for my career. My mentor has listened, guided and challenged me, and probably most importantly, has sponsored my progression. It’s not what people say about you while you’re in the room, but what they say and do to actively promote you when you are not present that will have a meaningful impact. To have someone who believes in you wholly and has all the qualities required to successfully advocate for you is a true gift, one for which I am extremely grateful.
Is there anything you’d like to see change in the industry to encourage more women to start a career in HVAC?
Lisa Stoneham: It is a common misconception that HVAC and refrigeration technicians are just electricians. As it becomes more common knowledge that they are separate, specialised trades, more people will be interested in joining.
The key is showing people the broad range of work available under the HVAC&R umbrella. It’s not just cleaning filters and checking temperatures.
Sarah-Jayne Cook: Beyond wider culture change, role models are vitally important in attracting fresh talent. After all, ‘you cannot be what you cannot see’. Role models make our goals tangible. Seeing others succeeding and pushing for their work to be the best it can be inspires us to do the same. Support and encourage those around you to shine as the strong role models you know they are.
Good role models will motivate their teams to do their best to excel at work, will lead by example, provide valuable career insights, and will help others to set realistic goals and plan for professional development. Ultimately, they will act as beacons for other women considering a career in HVAC.

Changes to vocational education and training
How will the future look for vocational education and training in New Zealand, and how does this impact our industry?
In 2024, the government consulted on the vocational education and training system. Subsequently, on 20 December 2024, the Minister of Tertiary Education and the government released some decisions on the new vocational education and training system.
“The redesigned system will better meet the needs of learners, industry, and the economy. It includes re-establishing regional polytechnics that are financially sustainable,” says Hon Penny Simmonds.
“A strong vocational education and training system contributes to New Zealand’s economic prosperity, and improves work opportunities and wellbeing for individuals, their families, and communities. Vocational education and training is crucial to support economic growth in regional economies, and helps retain young people and workers within those regions.”
Key changes:
• The Government has agreed to amend the Education and Training Act 2020 to disestablish Te Pūkenga and allow institutes of technology and polytechnics (ITPs) to be established as autonomous entities. These may be standalone or as part of a federation. Decisions on which polytechnics will be established, and in which form, will be taken in the first half of next year. These decisions will consider the needs of local communities, learners and industry.
• The standard setting functions currently delivered by Workforce Development Councils (WDCs) will be taken over by Industry Skills Boards (ISB), but further input is sought from industry on how work-based learning should be structured. WDCs will continue to operate in the interim.
• ISBs will take over the standard-setting functions currently delivered by WDCs. They will be responsible for national consistency and quality through assurance, moderation and programme endorsement.
• Workforce planning and advice to TEC functions will be retained as a function of the ISBs.
• Government has listened to industry regarding the importance of TEC advice and maintaining separation between standard-setting, and delivery and assessment.
• The approach to supporting work-based learning is not confirmed. Targeted consultation on two options covering the scope of the Industry Skills Boards and arrangements for work-based learning.
• The Government expects changes to happen progressively from January 2026.
What we don’t know about these changes so far:
• How many ISBs there will be.
• How many polytechnics there will be.
• The funding allocations across the VET sector.
• How ISBs will be funded and to what level.
• What the transition process will look like and who will manage this.
• What the requirements will be regarding pastoral care role.
• Whether the ISBs will have a role working with iwi and hāpū.
• Whether the ISBs will have a role related to underserved learners.

How New Zealanders are using energy
The Energy Efficiency & Conservation Authority has released its latest research, providing a snapshot as to how Kiwis use energy and their stance on adopting ways to be more energy-efficient
How are you using energy in your home or workplace, and if you’re a supplier in our industry, do you know how your customers are using energy?
It’s little surprise that most New Zealanders are concerned about rising energy prices, which are expected to continue. This is leading many Kiwis to adopt more energy-efficient ways.
The Energy Efficiency & Conservation Authority (EECA) surveyed 760 New Zealand adults between September 16–26, 2024, to learn about their energy use contexts, behaviours and attitudes. The sample was nationally representative based on age, gender and region, with 80% of the respondents being their household’s energy decision-makers.
Key findings
• More than 8 in 10 New Zealanders are concerned about household energy prices, with some taking steps to address these by investigating other retailers and factoring in energy efficiency when purchasing new appliances.
• Those concerned about energy prices want to learn more about improving their energy efficiency to lower their power bills.
• 81% of New Zealanders expect electricity prices to continue to rise, with a similar number (83%) expressing concern about this.
• The majority of New Zealanders say they pay a ‘fair amount’ of attention to their energy use at home. But only about half feel confident in understanding and managing their use.
• In the previous 12 months from September 2024, 44% have shopped around for a new gas supplier, with 14% engaging a new provider. 43% have shopped around for a new electricity supplier and 16% followed through.
The impact on appliances chosen by consumers
When it comes to energy awareness when purchasing products for the home, 46% of respondents were happy
to pay a higher price for a more energy-efficient appliance.
Another key finding was that more than 6 in 10 homeowners who did not already have solar installed were considering adopting rooftop solar systems in the future.
What this means for our industry
The importance of HVAC&R companies and suppliers knowing how customers use energy, whether it’s for heating, cooling, or refrigeration, can’t be overstated.
Suppliers need to understand not just how their customers use energy, but also what drives their purchasing decisions. If energy efficiency is top of mind, companies can tailor their offerings to highlight energy-saving features and benefits. Similarly, by understanding how energy is used in the home or workplace, HVAC&R suppliers can recommend systems and solutions that fit the customer's consumption profile, and recommend products that best meet customers’ needs, making them more likely to make the purchase.
Overall, understanding how customers use energy allows them to respond to rising energy concerns with more tailored, energy-efficient products and solutions. This not only helps meet the growing demand for energy savings but also positions businesses as knowledgeable and trusted partners in the energy-efficiency conversation.

3. Carson Electrical
Congratulations to Carson Electrical for winning the PlayStation 5 from Refspecs.
4. Ice Tech’s busy start to the year
6. Wire and Fittings’ new HVAC tools stand
Ice Tech recently had a York Screw Compressor in the shop for repair. It was safely removed and lifted from site and was in the clean workshop environment for the team to install a Mycom Recip and Mycom oil separator at a client’s ammonia plant. More recent work for Ice Tech includes using their new OEM toolkit to work on a GEA V series compressor.
5. Tubman Heating
A school radiator system was running on two old gas-fired boilers pumping hot water in a converted holding tank, costing $3,000 a month. The old system was replaced by a single wall-hung condensing boiler that offers 98% efficiency. This saw an immediate drop from $3,000 to $300 per month.
Another Navtek stand is set up and ready to go at J. A. Russell in Te Rapa!
7. Cuddon’s range of commercial freeze dryers
The perfect solution for products with high sugar or acid content. These machines are specifically designed to freeze these types of products gently and efficiently: https://lnkd.in/g4heRjWH

RESEARCH SURVEY ON DIGITAL TRANSFORMATION IN THE CONSTRUCTION INDUSTRY
A PhD student at the University of Auckland is conducting a study to gather insights into industry trends and challenges
The survey, titled A Decision-Making System for Digital Transformation is being conducted by UoA student Jieyu Bai, targeted to business owners and employees from vertical construction companies to gather insights into industry trends and challenges. After connecting with the New Zealand Construction Industry Council (NZCIC) via HERA, industry members who are suited to providing their views are encouraged to complete the survey.
A decision-making system for digital
transformation
This survey aims to understand what objectives are considered important by the industry in order to achieve digital transformation. The respondents are expected to be business owners or employees from vertical construction companies who have adopted, or are looking to adopt, digital technology in their organisations. The survey is anonymous and will take approximately 10 minutes to complete. The findings will help develop a roadmap for construction sector digital transformation. The results of the research will help construction SMEs customise their own objectives in order to embark on a journey of digitalisation success.
The research is approved by the University of Auckland Human Participants Ethics Committee, Reference Number 023682.
BRIAN REES RETIRES
On behalf of the industry, CCCANZ would like to thank Brian Rees for all the time and effort he put into helping with the standards committee over the past 25 years.
“It’s not always recognised or appreciated by those not involved, but without people like Brian giving their time and expertise, the industry wouldn’t be able to grow and adopt better practices. Thank you and enjoy your retirement, Brian – it is well deserved,” says Gary Reily, CCCANZ Chair.
Brian thanks CCCANZ for their support over his long tenure, sharing it has been a privilege and honour to participate and champion best practices on behalf of our wider industry.
The definition of each phase is as follows:
• Pre-Digitalisation Transformation Phase:
This phase involves assessing the organisation’s current state and readiness for digital transformation. It includes analysing internal and external factors, defining a digital strategy, evaluating digital maturity, preparing the organisation culturally and operationally for the upcoming changes.
• Ongoing Digitalisation Transformation Phase:
In this phase, digital technologies are implemented, and the organisation actively adapts to new systems and processes. It focuses on executing the transformation strategy, managing change, training employees, and identifying and controlling risks.
• Mature Digitalisation Transformation Phase:
This final phase involves optimising digital systems and processes that are already in place based on feedback and performance monitoring. The focus is on sustaining the transformation through continuous improvement, fostering innovation, ensuring data security, and maintaining digital leadership and expertise within the organisation.
