Why Is My Furnace Overheating?

Telltale signs of an overheating furnace are:

  • A burning smell
  • Furnace switching and off frequently 
  • A humming or a noise that’s not usual 

You must look out for these signs as they might cause further harm to your furnace and lead to more significant repair costs or even a complete furnace breakdown. A furnace overheats mainly due to the following reasons. 


Clogged Air Filter


A clogged air filter keeps your furnace’s heat exchanger from getting sufficient cool air. As a result, it will cause overheating, and due to its safety features, it will keep turning off often. Clogged filters also result in poor ventilation and the circulation of dirty air. Poor ventilation is also linked to overheating, hence adding to frequent breakdowns.


Damage to Internal Parts 


Your furnace works long hours to keep you warm during the harsh winter months. However, no matter the guarantee of their longevity, some parts of a furnace may malfunction and need replacement. These broken-down parts might also be a reason for your overheating furnace as the whole system is not working in tandem. A certified furnace repair in Lawrenceville, and Roswell, will meet all your replacement requirements. Furthermore, have your appliance serviced routinely. A well maintained and serviced furnaces are not only bound to last longer but will also save you in your electricity bills. Timely servicing also detects possible defects, saving you from higher repair/replacement costs. 


Reaching Its Shelf Life. 


If your furnace is constantly overheating and you have cleaned out your air filter and have all your furnace components well-maintained, it might be a sign that your furnace is getting old and has served its purpose. If you have kept good care of your furnace with routine servicing and maintaining good health of its components, it will last about 10-15 years. However, it’s not always wise to keep an old furnace around and have it constantly repaired and serviced. Have a technician look at your furnace and ask for estimates of your furnace’s future up-keeps. If it’s anywhere near or more than the cost of installing a new one, do not spend any more time and money on your old furnace.
