Battle Indoor Air Pollutants with UV Air Purifiers

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.

As reported by the Center for Disease Control, the Institute of Medicine (IOM) found there was sufficient evidence to link indoor exposure to mold with upper respiratory tract symptoms, cough, and wheeze in otherwise healthy people; with asthma symptoms in people with asthma; and with hypersensitivity pneumonitis in individuals susceptible to that immune-mediated condition.

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 air purifiers

As a part of an indoor air quality upgrade to your home, UV air purifiers bathe the cooling coil with intense UV-C light, helping to sterilize its surfaces and protect the quality of your indoor air. 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, healthier air and enhanced system efficiency.
