Furnaces are responsible for keeping homes warm and cozy, but to continue working efficiently, they require regular upkeep. Cleaning these appliances can not only help prolong their lifespan, but it could also improve their energy efficiency and keep your utility bills down. As the seasons change, take the opportunity to clean your furnace and work with a professional to repair any additional issues you notice with your HVAC.

A Guide to Furnace Cleaning

1. Clean the Surface & Mechanical Parts

Before cleaning, turn your gas heater off to avoid inhaling fuel vapors or turn electric heaters off to prevent getting shocked. Next, wipe down the heater’s exterior using a wet rag. Next, remove the door and burner cover to inspect the furnace's interior. Use a wet/dry vacuum to get rid of dust and debris on the burners, around the motor and blower, and other mechanical parts. Use the brush attachment to clean the fan blades and a crevice tool for hard-to-reach areas. If you see signs of soot, consult a professional, as this suggests poor combustion.

2. Replace the Filters

Filters keep dust particles in the air from entering the blower. To keep your device running at maximum efficiency, change your filters as often as indicated in your furnace manual—usually once every three months. If these are washable, clean them using a mild detergent and allow them to dry.

After this, switch on your furnace's power and gas and activate the burners. If the burners on your gas heater emit a wavering yellow flame instead of a roaring blue one, the unit needs and adjustment from a qualified heating systems professional.

3. Vacuum & Inspect the Ducts

When cleaning the ducts, use a high-powered vacuum with a HEPA filter to keep the dust from dispersing throughout your home. If your furnace has a humidifier, clean it using a descaler.

Duct leaks allow warm air to escape, compromising your furnace's efficiency. If you identify any cracks or fissures, have a professional inspect and repair them, particularly if they are over 3 inches in length.
