AroundClock 10.3.13In the same way that you worry about the food that you and your family eat, you should be concerned about the air in your home. By installing an ultraviolet (UV) light in your heating and cooling system, you will be taking a step to ensure better indoor air quality. Read on to find out how. 

Ultraviolet lights help to destroy mold and mildew in your HVAC system. Mold and mildew can create adverse health conditions for your family. UV lights also help to eliminate viruses, bacteria, spores and fungi. A fungal contamination, especially on the coils and ducts in your HVAC system, is dangerous. Infectious diseases, as well as allergic rhinitis, hypersensitive pneumonitis and asthma can all result from a dirty HVAC system.

UV lights work by irradiating pollutants in the air. These pollutants are sensitive to the wavelengths produced by ultraviolet lights. The lights penetrate the spores, bacteria and viruses and destroy them from the inside, creating a healthier environment. Air is cycled multiple times a day though your HVAC as it is drawn through the ducts; the more times air is exposed to the ultraviolet lights, the better.

Most experts recommend installing UV lights near the evaporator coil to eliminate mold and mildew in the moist regions of the equipment, and where the lights can be focused on the drain pan, and in the return air duct.

Installing ultraviolet lights in your home is a great idea, but running UV lights 24 hours a day can become expensive. Newer ultraviolet lights offer an automated option that can save you up to 80 percent on the operational cost. These save you money by automatically turning the ultraviolet lights on only when your HVAC is running.
