Spring cleaning should include your central heat and air system. The air conditioning system, which includes the furnace and blower assembly, evaporator coil, ductwork and outdoor unit (either AC or heat pump) cannot run effectively and efficiently if it is dirty. A dirty evaporator coil can become the cause for unhealthy air. Air must pass through this at a specific rate, called CFM (cubic feet per minute). This is important when it comes to comfort and efficiency. The blower assembly moves air through the furnace and evaporator coil and then through your ductwork and into your conditioned space.

 

Regular maintenance and cleaning is very important and can help to lower the cost of your utility bills and keep your unit running efficiently. Dirt effects the 3 main components of your furnace so cleaning it is the most important part of regular maintenance. The three parts of the furnace that should be cleaned includes the filter system, the blower and the motor.

 

Your furnace fan, typically called the blower motor assembly or the squirrel cage fan can become extremely dirty over time. If there is dust, dirt, pet hair or construction material in your ductwork, guaranteed it has accumulated in the furnace fan as well. It is critical to clean the blower assembly, belts and pulleys to the blower and motor housing especially if the furnace has a squirrel-cage fan, because openings in this type of blower often become clogged with dirt. You can check this by removing the panel that covers the filter to gain access to the blower or panel on the front of the furnace. We recommend you call a trained HVAC professional to clean this part of the unit.
