How to Change or Clean a Furnace Filter

One of the most common reasons we see for unnecessary service calls on furnaces is a failure to change the filter regularly.

The filter removes dust and dirt from the air as it passes through your furnace. Your furnace is responsible for distributing air throughout the house in the winter and summer so it’s important to keep your filter clean. If you have pets you may want to consider changing the filter more often as hair can cause the filter to clog more quickly.

Although the procedure may vary slightly by manufacturer, the following will give you a pretty good idea of how to change or clean the filter yourself.

 Your filter size and type can vary greatly by manufacturer but is easy to do yourself. Most manufacturers recommend changing your furnace filter every 30 to 60 days.

You can expect your furnace and air conditioner to run smoothly for many years with proper maintenance. Your heating and cooling system should be serviced twice each year–in the spring and the fall–before they are exposed to their most rigorous use.
