Mold and bacteria are pesky intruders that ruin indoor air quality. Airborne germs blow past your HVAC system’s filter and circulate around your home or business. Your air conditioning system’s indoor coil is part of what cools your home, but it can also be a hotbed of microscopic misery that affects air quality and a system’s efficiency. HVAC UV lights help to kill those bacteria and allergens as they blow through your system.
Why Do UV Lights Work?
Mold and bacteria don’t like ultraviolet light – to them, it’s a killer. UV lamps are proven to minimize the microbial build-up on coils, improving system efficiency and keeping mold and bacteria out of your system. All mold in line-of-sight of the UV bulb will be killed, keeping the coil mold-free.
Numerous health studies have shown that ultraviolet light is very effective against mold, mildew, fungi and viruses, bacteria and spores by breaking down their DNA or RNA. UV light has also been shown to play a role in secondary allergy prevention especially where airborne allergens are concerned.
How Do HVAC UV Lights Work?
HVAC UV light fixtures are designed to serve as HVAC air cleaner systems, but Ultraviolet lighting does not clean HVAC systems and should not be used as a substitute for HVAC duct cleaning.
There are two types of UV lights for HVAC systems:
- Coil Sterilization – A “stick type” light installed inside the return air duct near that sterilizes the air handler coil. A coil sterilization UV light runs 24/7 and is the most common type of HVAC UV light.
- Air Sterilization – A complete UV light unit that sterilizes moving air. The UV light unit is installed in the return air duct and cycles on with the air handler blower.
Benefits of HVAC UV Lights
The initial benefit of HVAC UV lights is improved indoor air quality, but there are many other benefits including:
- Control mold and bacteria
- Reduce colds and flus – germs are not recirculated by HVAC system
- Reduce smells/odors
- Remove VOCs
- Are more effective in humid climates than dry climates
- Reduces clogging in condensate drain lines by preventing algae growth
- Maintain a cleaner coil, improving cooling efficiency and reducing electricity costs
In addition to HVAC UV lights, regular coil cleaning and maintenance should be part of the measures to ensure optimum indoor air quality.
