Air Filters

Friday, February 20, 2009 by Larry Elkins

You should check your HVAC system filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool, wasting energy. A clean air filter will also prevent dust and dirt from building up in the system which can lead to expensive maintenance and/or early system failure.
