If you’re looking at ways to improve the air quality in your home, you may have seen some information about HVAC UV light systems. As we’ve mentioned in previous posts, these UV lights for your AC system or air handler can go a long way towards improving indoor air quality, reducing odors in your home, and improving the efficiency and longevity of your system, generally making your home more comfortable.
But how do they work? What makes these lights so effective at combating airborne allergens, mold and other nasties? We’d like to “illuminate” the UV light topic for you.
How An HVAC UV Light Works
The lamp is installed in your central air system, either right above or right below the evaporator coils. The ultraviolet light generated by the bulb (UV-C) penetrates the cell walls of mold and other microbes and scrambles their DNA. Think of these germicidal lamps as “death-rays” for mold and bacteria. UV-B light is normally filtered out by our atmosphere, so microorganisms have no defense against it. Any surface that the light shines directly on is fully sterilized within 24 hours of turning the germicidal lamp on, and any airborne microbes are killed as the air circulates through the system and passes by the lamp.
Mold thrives in the interior of your air handling system, since dark moist areas are mold’s best friend. By installing the UV lamp near the evaporator coil, the germicidal properties of the UV-C light prevent mold from growing on the coils, which helps improve the efficiency and longevity of your system.
Airborne biological contaminants are killed as the air circulates through the system. The EPA states that indoor air pollutants are often more harmful than outdoor pollutants. The UV light system kills mold, bacteria, viruses and other allergens. This greatly improves the quality of the air inside your home, and helps reduce odors.
An HVAC UV Light Is An Investment In Home Comfort
When you compare it to the benefits that an HVAC UV light system provides, the value in your investment is astronomical. The initial installation costs less than $500. A replacement bulb (installed) costs about $160. When you break that down over the life of the bulb, you’re looking at a monthly investment of less than five dollars to greatly improve the level of comfort and health of your home.
