When you want to cozy up away from the cold weather, it may seem as simple as switching on the furnace. If you’re starting it up after a long spring and summer of hibernation, though, cleaning the equipment is essential. Over time, dust and dirt particles—as well as exhaust—can accumulate on important parts, causing them to fail and leading to professional repairs from a heating contractor. To help ensure your heating system is ready to go, here are five furnace parts you should have cleaned during a tuneup.

Which Furnace Components Get Dirty?

1. Air Filter

Typically positioned at the base of the unit in front of the blower assembly, the air filter performs the all-important job of removing harmful contaminants and allergens from your indoor atmosphere. Over time, however, the filter will become clogged, which can impair your indoor air quality and lead to excessive energy use. To avoid problems, replace the filter about once every 90 days.

2. Ignition

The gas pilot light or electric ignition supplies heat to the burners to warm up the air. If this part gets too dirty during the off-season, it won’t be able to give the burners the jump-start they need to function.  

3. Burners

Burners combine air and fuel to produce heat, which is then distributed throughout your home’s ventilation system. When these components are covered in dirt, they generate heat inefficiently.

As a result, your heating system will have to run longer to produce the desired temperatures, leading you to incur high energy costs. An unclean burner can also produce carbon monoxide—a harmful gas that could put your family’s lives at risk.

4. Blower Assembly

The blower assembly is responsible for pushing air through the ductwork. When the fan blades get too dirty, they may slow down and move less air. Debris can also affect the assembly’s motor, which may eventually cause a breakdown that requires a heating contractor’s help.  

5. Exhaust Pipe

Exhaust pipes, also known as flue pipes, direct harmful gases away from the furnace to the outside of your home. If too much exhaust has built up within the pipe or outside debris has plugged it up, dangerous carbon monoxide gases can be pushed back into your home. When the exhaust isn’t able to exit the system, internal furnace components may also get dirty faster.
