How to Clean a Furnace

Dirty furnaces may waste fuel, create a burning smell, and slowly wear down and need early replacement. Therefore, it’s important for you to know how to clean a furnace, or to ask a professional to step in and do your yearly furnace maintenance. Here’s how you can get started, and where you may need a bit more help from the professionals. 

How to Clean a Furnace Filter 

Your furnace filter has a big impact on your air quality. It collects dirt and dust, but once it’s too full, it starts pumping that stuff back into your home. Most filters need to be replaced, not cleaned, every 3 months or more frequently if you have pets or allergies. It’s as simple as buying the same size of filter you have now and sliding it into place. 

If you have a furnace filter that can be reused, all you need to do is wash it gently with soap and water. If you notice the filter has cracked or warped, you need to replace it. 

How to Clean the Furnace Exterior   

While you are washing out or replacing your furnace filter, it is a wise idea to clean the dust off the furnace exterior. Too must dust build up will begin to burn off the furnace when it’s running, which can create a burning smell. All your furnace needs is a simple wipe down with a damp cloth. Be sure to get into any small corners, but do not clean inside the furnace. 

How to Clean Furnace Blower 

Dust will also build up on internal parts of the furnace including the blower and coils. The task of cleaning these parts are best left to the professionals, but it is possible to do them yourself if you understand furnaces and have some tools on hand. 

First, ensure the furnace is off and the gas is off before you begin. Then, unscrew the panel on the furnace. Remove the fan unit from the furnace and set it aside. Then remove the blower assembly. It can be washed by hand in soapy water. Some other internal parts can be removed and vacuumed too. 

How to Clean Furnace Ducts 

Your air ducts that connect to the furnace and run through your home should also be cleaned regularly to reduce dust in your home and improve the efficiency of the furnace. Clean ducts mean more efficient airflow, which delivers heat through your home faster and better. You’ll need an HVAC professional to clean your ducts as they need to create an access point and use special cleaning equipment.
