Five Steps to Improve Indoor Air Quality

Does the air in your home seem smelly, stuffy, or otherwise polluted? You may already be experiencing airflow problems with your A/C system. To improve your home’s indoor quality, here are 5 simple steps that you can take:

  • Vent combustible appliances such as heater and furnaces away from the home.
  • Install ventilation systems—such as exhaust fans—in kitchens, bathrooms, and laundry rooms. Be sure to use quiet, energy efficient fans.
  • Don’t place any part of your home’s heating and air conditioning system in polluted spaces where they could pull contaminants in. If ductwork needs to pass through a polluted space, make sure they are properly sealed so they won’t pick up contaminants or leak out air.
  • Keep potentially harmful substances such as pesticide, solvents, and paint away from intake vents.

  • Use a high-efficiency particulate air (HEPA) filter in your A/C system. These filters trap particles including allergens like pet dander, pollen, and dust mites. They can also capture irritant particles like tobacco smoke. Replace your filter once a month for optimum results.


If you’ve done all of the above and still feel your indoor air quality hasn’t improved, it’s time to call in a certified HVAC professional for a thorough evaluation of your system.
