Many factors contribute to poor indoor air quality. Your home’s air conditioning system may be one of those factors. With that in mind, let’s discuss one way to maintain your home’s a/c system and contribute to a healthy indoor environment.


The a/c systems filters play a huge role when it comes to indoor air quality, so they need to be changed regularly. How often? As a general rule, you want to replace the filters every three months, but there are some circumstances where you would want to change them more often than that. For example, if members of your household suffer from allergies, it would be a good idea to change the filters more frequently. You may also need to change the filters more often in larger households where there are pets or smokers in the house.


A further reason that you may need to change the a/c or HVAC systems filters is your home’s location. Are you surrounded by agriculture? Is there any construction going on around you? An outdoor environment such as this could affect the air you breathe indoors, changing the filters regularly will help with this.


If you notice that the filters in your a/c or HVAC system are damp, wet, or damaged in some other way, they should be replaced immediately, even if you have not had them very long. Damaged filters can contribute to unhealthy air quality and promote the growth of mold and bacteria.
