How to Clean Your Furnace Pump

Posted on

In a central HVAC system with forced air, the furnace pump is essentially the muscle of the operation. That is, it pumps both heated and cooled air through your ducts and into your home. Basically, if your pump is not in good working order, your system will suffer reduced airflow. Cleaning your furnace pump on a regular basis is the best way to prevent blockage that could decrease the efficiency of your system and force you to use more electricity when heating and cooling your home. This article explains some basic furnace pump maintenance that you should perform every 12 months. This preventative maintenance will keep your HVAC system productive and affordable to run.

Finding the Furnace Pump

First, you need to find the furnace pump. It is inside the main furnace cabinet. Most cabinets have an access panel or door right on the front. The actual pump is a surprisingly small component. Some people expect to see a huge fan with large blades inside the furnace. The pump is inside a plastic box. There is a small fan inside the box that you can often see when you look through the vents.

Cleaning the Furnace Pump

Cleaning the furnace pump is important. If the pump vents are clogged with dust or dirt, it will block the ventilation. Usually, this causes it to run hot and suck up more electricity in an effort to cool down the motor. Basically, even a small bit of dust clogging the vents can slow down your system.

The best way to clean your pump is to suck away the dust and dirt with a hose vacuum. Use a brush attachment for your vacuum so you can knock loose the dust that is stuck to the plastic box. If you do this every year, your furnace will only have a moderate amount of dust build up.

If you do clean your furnace pump every year, and there is always a lot of dust on it, there could be a problem with your furnace. This most likely means that your furnace filter is not working properly. It might be due to the fact your filter is super dirty or it is just improperly installed.

Either way, your furnace pump is closely connected to and dependent on your filter, so it is important that you do your best to keep both clean at all time for an efficient system.
