Why Does My Furnace Keep Shutting Off?

There is usually a sense of anxiety when you recognize something isn’t quite right with your furnace. You’re relaxing at home and you notice your furnace is endlessly kicking in and shutting off. However, before you panic, there are a few things you can check when you first notice that your furnace seems to be shutting off a lot more 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 air in your house cleaner, but the filters also support keeping your system clean. Your first step when you notice 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 several of us, we may have set our thermostats several months ago and forgot about it, particularly when using a smart or programmable thermostat. Examine your thermostat to see if anything unfamiliar is going on or if it might need new batteries. The location of your thermostat could make a difference, as well. If it’s located in a place that’s often hotter than the rest of your space, such as in direct sunlight or by another heat source, it could be wrongly assuming your home reached 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 often. Walk around your home and check the windows to make sure they are all closed and take a look at the seals around your windows for any drafts or cold air entering into your house.

While you can look at these issues by yourself, if issues still persist after these checks, it might be time to call in the experts. When your furnace is consistently turning off, it can lead to unnecessary work and stress on your system that could lead to more expensive repairs or even a replacement.
