If your furnace is overheating, you may worry about your family’s and home’s safety. Furnaces can overheat for a variety of reasons, but it is usually something you can fix fairly easily. Here are some reasons why your Hartsville, TN furnace overheats.
Dirty Filter
Your furnace will overheat because the filter is dirty. A dusty or clogged filter prevents air from properly flowing through the HVAC system. This causes the heating system to work harder to circulate air and can cause it to overheat.
Ductwork Issues
Damaged, blocked or too small ductwork can cause your heating system to overheat. Damaged ductwork can leak air, which makes it work harder to circulate air. Blocked ductwork can prevent air from flowing through the system properly.
Leaks in the ducts can cause cool air to escape and warm air to enter. This puts extra strain on the furnace and can cause it to overheat.
Thermostat Issues
If your thermostat is not working properly, this can also cause your heating system to overheat. If the thermostat is set too high, the furnace will work overtime to reach the desired temperature. This can cause it to overheat and interfere with the unit’s normal operation.
Furnace Maintenance
One of the best ways to prevent your heating system from overheating is to have it serviced regularly. A professional can clean the filter and inspect the ductwork for leaks or other issues. They can also check the thermostat to make sure it is working properly.
Mechanical Failure
Failure of some major components in the furnace can cause it to overheat. These parts include the blower motor, the heat exchanger and the igniter. They play a critical role in the operation of the heating system, and if they fail, it can cause the unit to overheat and shut down.
