Air filter change… How often really?

For your health as well as the life of your HVAC system changing your filter every month is a good plan.  Not only are you reducing pollen, dust and other allergens, you are also keeping dirt and other particulates from building up in your system.  This build up can lead to your system failing earlier than it should.  Your air conditioner or heat pump will have to work harder to push air through a dirty filter.  Keeping you cool this summer shouldn’t mean a higher than necessary electrical bill either.

Check on the filters every month.  If it is dirty, replace it.  Otherwise, replace that filter, at the very least, every 90 days.
