Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dismay when you notice something isn’t quite right with your furnace. You’re resting at home and you realize your furnace is endlessly kicking in and shutting off. However, before you panic, there are several items you can check when you realize your furnace seems to be shutting off more frequently than it should be.

  1. Check the air filter in your furnace—You may think that air filters are only used to help keep the indoor air cleaner, but they also work to keep your system clean. Your first step when you recognize an issue with your system should be examining your air filter to see if it needs to be replaced. If it’s clogged or dirty, it can make it hard for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots of us, we may have set our thermostats weeks ago and forgot about it, even more so when using a smart or programmable thermostat. Examine your thermostat to see if anything unfamiliar is going on or if it may need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s typically hotter than the rest of your space, such as in direct sunlight or near another heat source, it could be wrongly assuming your home is already up to the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have the right insulation, your furnace is likely to shut off more frequently. Walk around your home and check the windows to confirm they are all closed and take a look at the seals around your windows for any drafts or cold air coming into the house.

While you can certainly check for some of these issues yourself, if issues still continue after these checks, it might be time to call in the pros. When your furnace is always turning off, it can lead to unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
