Heating Your Home

You need to change your furnace filter at regular intervals both in winter and summer. Regular intervals would be at least quarterly. We have recently seen some filters that were almost completely clogged. Think of the furnace filter the same as your air filter in your car. If it gets dirty or clogged, your engine will not run very efficiently, nor will you get the gas mileage you should. The same is true with your furnace and air conditioner.
