When should I change my home's AIR FILTERS?


They do more than you think...
Did you know that the filters on your forced air furnace serve more than just one purpose?  They not only clean the air that circulates throughout the home, they also control dust particles, and the higher end filters can even control allergens.

But one purpose that most homeowners overlook is the fact that a higher end filter helps keep the evaporator of the central air conditioner clean.

I have found many furnaces missing the filter completely during an inspection.  Homeowners may claim that removing the filter has improved air flow to the upper levels of a home.  What they do not realize is the dirt that the filter would trap is now being caught by the evaporator which typically sits on top of the furnace, and in turn will eventually lessen the air flow and shorten the life of both the A/C unit and the furnace.  Having the evaporator removed and cleaned may cost up to $400.  Maintaining a clean filter is inexpensive and allows the components to operate more efficiently. 
Filters should be checked monthly and replaced or cleaned every 1 to 3 months to ensure maximum efficiency.

Don't overlook this important part of regular home maintenance, as the air your family breathes is important!
