How Does a UV Light for HVAC System Work?

The system shines UV light at the 254-nanometer wavelength. When absorbed by the microbe’s DNA, the UV light damages nucleic acids and prevents the organism from reproducing. Keep in mind that UV light works only for live organisms. It’s not effective for pet dander, dust and other allergens.

Types of UV Light for HVAC Systems

You can choose from two basic types of UV light systems. The options are coil sterilization and air sterilization.

The coil sterilization system places the UV lamp in the air handler near the evaporator coil. The UV light shines on the cooling coils, condensation pans and filters, killing viruses and bacteria that collect there.

With cleaner air handler components, fewer microorganisms get into the air. Coil sterilization is the more common and cost-effective option.

The air sterilization system places the UV lamp in the return air duct, where it cleans the air that passes through. The UV light turns on when the cooling system is running and off when it stops running.

A UV light can clean biological growth and microbes from the air in your home in South Mills, NC. Call Weather Makers to find out if a UV light for the HVAC system is right for your home.
