Consider Adding UV Lights to Your HVAC System in 2015

If you have a forced-air heating and cooling system, you can make it do more for you than keep you comfortable winter and summer. Many homeowners aren’t aware that they can add ultraviolet (UV) lights to it to help clear the air. UV light is a wavelength found in sunshine that has a powerful effect on many organic substances, including mold spores, viruses and bacteria.

How UV Lights Work

Using these lights in your system will alter the DNA of any organic substance that passes over it, rendering them too damaged to reproduce. These lights expose all the air passing through the air handler and the ductwork to these rays, making it an effortless way to achieve cleaner air without using potentially harmful chemical disinfectants, particularly during the cold and flu season.

The lights can be placed inside the air handler near the cooling system’s evaporator coil, where they’ll shine on the coil and prevent mold from spreading during the summer. This coil is an ideal environment for mold growth because it condenses the water from your home’s air when the A/C is running. It warms up when the system shuts off, providing more ideal conditions for growth.

Mold covering the evaporator coil reduces a system’s energy efficiency because the air blowing over it can’t make direct contact with the coil. If you use a heat pump, this covering will drive up energy costs winter and summer. You can also place the lights inside the ductwork in strategic places to sterilize the organic particles as the air blows through.

UV rays have the potential to harm eyesight, but when placed inside enclosed ductwork and near the evaporator coil, they cause no damage. They do need to be replaced annually, but the bulbs promote energy efficiency for an HVAC system and safeguard your health. Considering the cost of running your heating and cooling system, the lights are an affordable way to help keep it clean.
