Having a dirty blower wheel will make your HVAC system work harder and, if not addressed, eventually cause your AC system to stop working.

A dirty blower wheel will also contribute to a high electric bill. Damage caused by a dirty blower can be costly to fix– but can be prevented too! So, what can you do to keep your blower wheel clean and prevent unnecessary problems?

In this article we will explain the role of the blower wheel in your forced air HVAC system And what you can do to keep it clean and operational.

The blower wheel to your HVAC system is out of sight and out of mind. It’s not like the air filter that you know you need to change regularly. The blower motor plays an important role in your forced air HVAC system and your comfort. It’s what triggers and circulates the conditioned air through your home. A breakdown of your blower motor can be the result of many things…old age, failed bearings, high amp draw, electrical failure in the windings, and DIRT accumulation.

If your HVAC system stops working due to a problem associated with the blower motor it will need to be diagnosed and fixed by a trained HVAC service technician. What we have determined, and know as an HVAC repair contractor in Northern Virginia, is the most common cause of a failure to your blower motor (and HVAC system) is the accumulation of dirt and this dirt is due to lack of maintenance.
