Healthy Buildings Start With Cleaner Air
Airtech UVC & Air Purification Systems
What's Growing Inside Your HVAC System
Your HVAC system can be circulating more than air
Moisture + dust + organic material + temperature = an environment where microorganisms can grow.
What is Toxic Biofilm?
Toxic biofilm is a buildup of microorganisms such as mould, bacteria, and fungi that can develop on damp HVAC components, particularly coils and drain pans. This slimy layer can negatively impact both air quality and system performance over time.
Biofilm buildup may
Reduce HVAC efficiency by restricting airflow and insulating coil surfaces
Spread airborne contaminants throughout indoor spaces
Cause unpleasant odours, corrosion, and increased equipment wear
AirTech’s UVC technology helps prevent and break down biofilm at the source, supporting cleaner systems, improved indoor air quality, and more efficient HVAC performance.
AIR PURIFICATION BACKED BY SCIENCE
UVC Light - How it works
UVC light is a powerful air purification technology that works by disrupting the DNA and RNA of airborne contaminants such as viruses, bacteria, and mould spores, preventing them from reproducing and spreading. Operating at the optimal germicidal wavelength of 254 nanometres, UVC technology actively helps create cleaner, healthier indoor air.
Widely used overseas for advanced air purification, UVC systems are becoming an important part of modern indoor air quality standards. With new regulations such as ASHRAE Standard 241 focusing on reducing airborne disease transmission in buildings, AirTech is ready to help New Zealand homes and businesses stay ahead with effective, proven UVC solutions.

New Zealand's Indoor Air Quality Specialists
AirTech helps New Zealand homes and businesses create cleaner, healthier indoor environments through advanced UVC air purification technology. Our systems integrate directly into existing heating, ventilation, and air conditioning (HVAC) systems to improve indoor air quality, reduce HVAC maintenance, and support healthier buildings.
Modern buildings are designed to be energy efficient, which means they often have less fresh air exchange. As a result, airborne bacteria, viruses, mould spores, and other microscopic contaminants can accumulate indoors, contributing to the spread of illness and triggering allergies, asthma, and other respiratory conditions. While traditional air filters capture dust and larger particles, they do not actively neutralise many airborne microorganisms.
Our UVC technology works within your HVAC system to continuously reduce airborne germs and help keep coils, ducts, and internal components cleaner. By treating the air where it circulates, AirTech systems help create cleaner, fresher indoor environments while also improving HVAC efficiency and reducing ongoing maintenance requirements—all without chemicals or added pollutants.
Whether you're looking to protect your family at home or improve air quality in offices, schools, healthcare facilities, hospitality venues, or industrial buildings, AirTech provides tailored UVC solutions designed to suit your space, your system, and your goals.
Cleaner air. Cleaner HVAC systems. Lower operating costs.
Return on Investment That Goes Beyond Clean Air
Installing UVC technology isn't just about improving indoor air quality—it's about reducing ongoing operating costs.
By keeping HVAC systems cleaner, reducing biofilm build-up, and helping minimise airborne contaminants, Air Technologies' solutions can deliver measurable value over time.
✔ Lower HVAC maintenance costs
✔ Improved system efficiency and performance
✔ Extended equipment lifespan
✔ Reduced downtime and cleaning requirements
✔ Healthier indoor environments that can help reduce staff absenteeism
Cleaner air. Smarter buildings. Long-term savings.
Improve HVAC Efficiency & Reduce Energy Costs
Cleaner HVAC systems can work more efficiently.
AirTech UVC systems help prevent the build-up of mould, bacteria and biofilm on HVAC coils and internal components, helping maintain clean heat-transfer surfaces and consistent airflow. By keeping your HVAC system cleaner, UVC can support more efficient operation, reduce the strain on equipment and help minimise unnecessary energy consumption over time.
For commercial buildings, this can contribute to lower operating costs, improved HVAC performance and a longer equipment lifespan — making UVC a smart addition to an energy-conscious building strategy.
Cleaner systems. Better performance. Smarter energy use.

Testimonials
"Air Technologies supported us on a restaurant HVAC system upgrade project in Christchurch. The job required careful coordination around existing system restrictions, with after-hours work needed to avoid disruption to the kitchen operations.
Jono and Levi were great to deal with throughout the project. They were responsive and supportive during the works, and continued to assist us after the job was completed to ensure the installed UV system was operating properly.
Air Technologies were a pleasure to work with, and we look forward to the opportunity to work with them again." - Max S, Beattie Air, Christchurch
Testimonials
"Levi showed us the bacteria in our old unit - it was disgusting. He recommended installing the UVC lamp which gets rid of the bacteria. Since my bone marrow transplant my immune system has not been as good. I have not been sick at any stage since the UVC lamp installation. This has been very successful for my situation." - Ken T, Tauranga, NZ

Unlike chemical disinfectants, UVC light does not produce harmful by-products or contribute to antimicrobial resistance. Its use in air purification systems reduces the need for harsh chemicals, creating a healthier and more environmentally friendly indoor environment for patients, staff, and visitors.
Cleaner Coils - UVC prevents biofilm accumulation on heat exchange surfaces, maintaining optimal thermal efficiency.
Lower Energy - Clean coils transfer heat more efficiently, reducing HVAC energy draw - typically 10-25% improvement in coil efficiency
Less Chemical Cleaning- Reduced frequency of chemical coil cleaning interventions, lowering chemical use, water consumption and contractor costs
Lower Lifecycle Costs - Extended service intervals, delayed capital replacement, and reduced maintenance spend across the HVAC asset lifestyle
