Battle Indoor Air Pollutants with UV Lights

As the temperature outside starts heating up, your air conditioning system starts going to work, pumping out that cool, chilled air that makes it easy to enjoy the comfort of your home.


Working tirelessly in the background, your air conditioning system chills the air through a continuous cycle of circulating warmer indoor air over a cool evaporator coil. The coil is generally out of sight somewhere in the depths of your basement, a utility closet or maybe out in the garage. And while that all sounds innocent enough, the dark, damp environment around that indoor coil is the perfect breeding ground for organisms that can invade your home and rob your HVAC system of energy efficiency.

Problem: Indoor air pollutants

Mold spores, bacteria and fungi can invade the surfaces of your cooling coil. Left unchecked, buildup of these contaminants can reduce system efficiency and release potentially harmful pollutants such as mold spores and unpleasant odors into the air you breathe.

Your HVAC equipment can suffer as well. As these living organisms continue to build up on your cooling coil, they can cause:

  • Reduced or obstructed airflow
  • Reduced AC system efficiency
  • Potentially shorter equipment lifespan
  • Increased utility bills

Solution: UV Lights

As a part of an indoor air quality upgrade to your home, UV lights bathe the cooling coil with intense UV-C light, helping to cleans its surfaces. UV lights are mounted inside your system, near the indoor cooling coil, where fungus and microbes may grow and pollutants can collect. No cleaning is required. Simply contact your local Carrier HVAC contractor to replace the lamps once a year and you can continue to enjoy cleaner air and enhanced system efficiency.
