What is the No. 1 Problem That Causes A Furnace System Fail?

Posted by Paul Wadsworth on Wed, Nov 16, 2011 @ 10:41 AM

Want to know what you can do to prevent the no. 1 problem that contributes to a furnace system failure?

Clean Air Filter

Unlike many of your home appliances, your furnace is a necessity, not a luxury. Yet, while people perform a weekly dusting ritual on their high-definition televisions, furnaces often sit alone in the basement for months at a time. Neglecting your furnace can be a costly mistake. The number one problem that contributes to furnace failure isn’t a mechanical failure -- it’s forgetting to change the air filter regularly.

Furnace filters come in all sizes in a variety of materials to keep your heating system clean. What they do is filter dust, allergens and dirt out of the air as it reaches your heating and cooling equipment. If a filter is old and worn or overly full, it starts to fail, and the grime gets in to your system. Once inside, that debris can coat the blower and mechanical parts, causing a significant decline in efficiency. Your system has to work harder, and the harder it works, the more prone it is to sporadic failure. Failures mount until your unit completely shuts down.

How often should you change your filter? It depends on the type of filter, how often your system runs and how dirty the air is. But you should check it monthly and replace or clean it when it's dirty -- at least once every one to  three months is a good rule of thumb. Consult your furnace’s manual for exact filter size and specifications.  You can also sign up to receive free email reminders on when it is time to check your filter.
