What Maintenance Is Performed on a Furnace?

Are you considering a maintenance agreement for your furnace?

Furnace Maintenance

If you’re considering a maintenance agreement for your furnace, you might be wondering what exactly that agreement includes. If you’ve never had regular maintenance on your HVAC system, it can be a bit of a mystery. Here are some of the basic checks performed during the typical furnace maintenance service visit:

Combustion Chamber

The combustion chamber is where the fuel mixes with air and is ignited to generate heat. During the combustion process, soot can build up on the walls of the chamber. Soot is highly corrosive, so soot left inside the chamber can cause corrosion, damaging the interior. During maintenance, the chamber is cleaned and inspected to be sure there is no internal damage.

Flue Pipe

The exhaust from the furnace moves out of the house through the flue pipe. Inspecting the flue pipe is vital to the safety of you and your family. If there are any cracks or leaks in the pipe, carbon monoxide can leak into your home creating a dangerous and possibly lethal situation. Any holes or cracks will be repaired or, if necessary, piping will be replaced.


The blower does just that; it blows heated air from the furnace into your house through the duct system. Because it’s driven by a motor, the belt can become too loose which makes your furnace less efficient. Adjustments to the motor can fix the belt. If the belt is worn, it will need to be replaced.


The motor runs the blower, allowing the furnace to provide warm air to your home. Like most motors, it consists of moving parts. Regular maintenance agreements will include inspection of the motor and lubrication of all of the moving parts.

Annual furnace inspection is a great way to ensure your furnace is in top working order. Any small issues can be fixed before they become big problems, and your furnace can get the TLC it needs to keep running efficiently all year.
