Why Doesn’t My Furnace Turn Off in Surf City, NC?

Everyone likes to feel warm and cozy in their Surf City, NC, home during fall and winter. What should you do though when your furnace won’t shut off and your home starts to feel uncomfortably warm? Below are five potential reasons your furnace won’t turn off along with ideas to remedy the problem.

Thermostat Isn’t Set Properly

This happens often. Simply check your thermostat and make sure that the switch is set to AUTO so that it can shut off automatically when it reaches your desired air temperature. When the thermostat is accidentally set to ON instead, the fan will blow continuously regardless of the temperature setting.

Filter is Dirty

Most HVAC filters need replacing every three months or so, but some factors might lead you you needing to change your air filter before the three-month mark. When your filter gets clogged with dust, pet dander, cooking grease residue or other contaminants, it needs changing. Simply replace with a new filter or clean it according to the manufacturer’s specifications.

Broken Thermostat

If the two above quick fixes won’t solve your problem, it’s time to call in the pros. The thermostat itself might need replacing. Be sure to ask your local furnace repair service technician about the best type of replacement thermostat, as some newer models can actually help you save money on your heating bills.

Fan Blower Motor or Fan Limit Switch is Faulty

Another cause might be the fan that blows warm air through the home. If the limit switch is faulty or not set properly, it could be unable to switch itself off. The fan motor itself may need replacing.

Ductwork Has Leaks

Lastly, all the other components might be functioning perfectly. But if you have leaks in your air ducts and hot air is escaping, it’ll take forever to warm up the whole house. You’ll need to have your ductwork professionally inspected and sealed to keep the air flowing properly.
