How Do HVAC UV Lights Improve Air Quality?


What’s this UV light hocus pocus and what’s it got to do with my indoor air quality?

UV light can and will improve your indoor air quality. Want to know how? Let’s look at how HVAC UV lights work and how they can help you breathe easier.

A Little Background

UV light will breakdown and incapacitate bacteria and microbes. It started in 1903 when doctors used it to treat tuberculosis. Since then its uses include disinfecting hospitals, water supplies, laboratories, kitchens, and more.

What’s in My Air?

The big concern with your indoor air quality is the presence of mold, mildew, and bacteria. There’s a probability they’re present in your home, ducts, and HVAC system. Because of this, the air in your home is also full of those air pollutants, and they recirculate daily via your HVAC system.

A UV Light Can Change Your Indoor Air

Ultraviolet light damages the DNA in mold and bacteria. The damage to the DNA in the cells causes them to self-destruct and become harmless. An ultraviolet light installed in your air handler exposes all of the air that passes through your HVAC system to its light properties. As the system pulls air into the return air duct the UV light sterilizes it before it ever enters your HVAC equipment. This means the air that circulates through your home by way of your ducts and vents is significantly cleaner than the air in a house without UV light.

If you want to control mold and bacteria, reduce the instances of colds and flu, and reduce odors in your home, it’s time to consider some UV light treatment in your HVAC system. Contact the experts at H.H. Hovey to find out more about how you can improve your indoor air quality.
