During the cold winter months, you rely on your heating system to keep your home warm and cozy. A furnace breakdown can throw a wrench into those plans. The problem sometimes occurs when parts wear out or become damaged, but it’s often a result of simple dirt and debris buildup. If your furnace hasn’t been cleaned or tuned up in a while, prevent an imminent cold night by learning about the following components.

4 Furnace Parts to Keep Clean

1. Air Filter

Your furnace filter purifies intake air before circulating it through your home. Over time, air filters collect dirt and debris, and when they become saturated, your furnace will work harder to push air through and heat your space.

If your HVAC system is equipped with a permanent filter, be sure to clean it regularly. Most modern homeowners use disposable filters, which should be replaced at least once every season.

2. Ignition

Most heating systems use pilot lights or electric ignitions. When these become soiled, your furnace may struggle to light. To clean the ignition, shut down the power to your furnace, then use a screwdriver to remove the igniter. Scrub dirt buildups with sandpaper and wipe the igniter with a cloth before replacing it. 

3. Burners

Burners tend to collect dirt and debris, which causes them to heat unevenly as they struggle to reach the correct temperatures. Clean them by shutting off the electricity or gas, then open the panel to unclip the burners. Use a soft-bristled brush to scrub off dust and corrosion, then vacuum the interior of the unit before putting the burners back in place. 

4. Thermocouple

Many furnaces have thermocouples, which automatically shut the unit off when it gets too hot or burns improperly. When the thermocouple becomes dirty, it may not perform this safety function when needed. Prevent fire and carbon monoxide hazards by removing dust and debris with compressed air.
