Air Conditioner Maintenance: How often should the Filter be Replaced? Air Conditioner Maintenance: How often should the Filter be Replaced?

Air conditioner maintenance involves many aspects including changing the filter, but how often should the filter be replaced? How often you replace the filter on your air conditioner may depend upon how much you run it and several other factors in your home.

Pets and Allergies

If you have pets that shed hair this hair can be pulled into your duct work and your air conditioner and furnace. This will require that it be changed more often, perhaps as often as once a month when its very warm and the air condition is working hard. The same holds true if you have people in your home who suffer from allergies such as dust, mold and pollen. Keeping the filter clean will make them more comfortable. It will also create less dusting and vacuuming for you.

Filters

Depending on what type filter you use may also influence how often you change it. Basic, flat filters need to be changed every 30 to 60 days. The pleated type that advertises cleaning less often may only need changed every 6 months. These are advertised as heppa filters in most areas. You will need to use your own judgement on these as they vary greatly in price.

Check your filter often to see how dirty it is and use this as a guide as to how often to change it, based on usage. This is over all the best guide. Keep a supply of filters on hand so you can change as needed.
