There are a few reasons a furnace might overheat, but most often the issue can be traced back to airflow. If your furnace isn’t receiving enough air, not only can this lead to heating issues in your living space, but it can also cause malfunctions, or in extreme instances, even ignite a house fire. Read on to learn more about furnace repairs.

Signs Your Furnace is Overheating

Most of us don’t fully understand how things work in our homes. But basically, your furnace is responsible for warming air that is then circulated throughout all the rooms in your house. This is a big job for one little furnace.

Here are 3 signs you need a furnace repair:

  • Your furnace has begun to make strange sounds, or at least, stranger than usual. This may include banging or humming noises, and it can point straight to an overheating issue.

  • Another sign things are getting too heated is if your furnace gives off a burnt smell. Although, if you haven’t run your furnace for a long time, this might just be the dust burning off.
  • And finally, if your furnace shuts off without reaching the temperature indicated on your thermostat, it’s likely overheating and being shutdown by the safety mechanism.

If you’ve determined that your furnace is overheating, check the vents. They could be blocked by furniture, compromising the airflow. Or maybe you even closed some vents to save on heating costs.

Next, change out the air filter. It blocks things like dirt, but eventually, this can lead to a buildup. Clogs can definitely cause your overheating issue. We recommend swapping out your filter every three months, just to be safe.

You can also examine the evaporator coil and blower fan. If either becomes too dirty, they won’t function properly.
