Indoor air pollution is a real, and often unseen hazard in many homes. Common pollutants wreak havoc on your comfort and health, and you may not even be aware of their existence. Luckily, your HVAC contractor has the solutions you need to fight these comfort-killing indoor air pollutants.

Common Indoor Air Pollution Problems


The air inside your home is typically far more polluted than outdoor air. This is usually due to a lack of natural ventilation, as homes are tightly sealed to conserve heating and cooling energy. Indoor air pollution is a problem that often goes untreated, as it is out of sight and out of mind.


The following are different sources of indoor air pollution that may be lurking in your home.

  • Combustion byproducts like carbon monoxide, produced by fuel-burning appliances or cars in attached garages
  • Smoke from tobacco use, cooking, or a wood-burning fireplace
  • Household cleaners, air fresheners, and even perfumes
  • Building materials that contain asbestos or volatile organic compounds (VOCs)
  • Excessive moisture, which may cause mold and mildew growth
  • Exterior pollutants tracked into the home such as radon or pesticides

Combat Indoor Air Pollution Problems


To fight indoor air pollution, there are many indoor air quality systems and solutions that remove contaminants and improve the cleanliness of your air.

Air filters


Changing your air filter on a regular basis and using a high-efficiency filter with a MERV rating of 8 to 12 eliminates more indoor air pollution. Change your filter at the frequency recommended by the manufacturer, or more frequently depending on usage and household factors.

HVAC system tune-ups


An HVAC system tune-up not only works to improve the performance of your equipment, but benefits indoor air quality as well. When your HVAC system is operating at peak performance and efficiency, it does a better job at filtering out contaminants that diminish indoor air quality.

Air purifiers


Whole home air purifiers are up to 99 percent effective in removing indoor air pollution. They work with your heating and cooling system, removing indoor air pollution as the HVAC system circulates air through your home.

Ventilation systems


Ventilation systems expel stale, contaminated air from your home, ridding it of indoor air pollution. Air is exchanged for fresh, outdoor air and filtered through your heating and cooling system.

Ultraviolet lights


Ultraviolet lights are a type of air purifier that are especially helpful in the removal of mold, bacteria, and viruses. These lights are installed within your heating and cooling equipment and neutralize particulates as they pass by. These pollutants are rendered ineffective and can no longer reproduce.



Too much moisture in your home creates a breeding ground for mold and mildew. Dehumidifiers work with your heating and cooling equipment to pull excess moisture from your indoor air, reducing the chances that these harmful contaminants may grow inside your home.
