Furnace Filter

Did you know that changing an air filter in a furnace will help eliminate problems with air conditioners and furnaces. Missing or dirty filters will cause the coils in an air conditioner to collect dust and malfunction. Furnaces are forced to work harder and will wear out prematurely with a dirty or clogged filter. Remember this when looking at a property that are not maintained properly. Filters should be changed at a bare minimum of once every three months.
