One of the most common problems we encounter on service calls is dirty filters. Many homeowners are very diligent at inspecting and replacing dirty filters but unfortunately too many are not. Typically, furnaces that are located in the basement or utility room are serviced more regularly than those in a crawl space or attic. The bottom line is that filters are the cheapest insurance to protect equipment. To be proactive you should inspect the filters every month and replace them.

The most common problems arising from dirty filters are:

Freezing the evaporator coil in the cooling season which results in no air coming out of the registers.

Registers, in case you don’t know what they look like:

Short cycling of the furnace in the heating mode. Dirty filters restrict airflow which causes the furnace to overheat. A continuous pattern of short cycling can cause premature failure of the heat exchanger.
Restricted air flow can increase the amp draw on the blower motor which can burn up the motor.
