Why Does My Furnace Keep Shutting Off?

There is usually a sense of dread when you realize something isn’t quite right with your furnace. You’re resting at home and you notice your furnace is endlessly kicking in and shutting off. However, before you panic, there are some things you can check when you first notice that your furnace seems to be shutting off more than usual 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 support keeping your system clean. Your first step when you notice a concern with your system should be checking your air filter to see if it needs to be replaced. If it’s clogged or dirty, it can make it tough for air to flow over the heat exchanger.
  2. Look at your thermostat—For many of us, we may have set our thermostats months ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything strange is going on or if it may need new batteries. The placement of your thermostat could make a difference, as well. If it’s located in a place that’s usually hotter than the rest of your home, such as in direct sunlight or close to another heat source, it could be falsely assuming your home is already up to the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have proper insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to ensure 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 review these issues on your own, if issues still persist after these checks, it might be time to call in the pros. When your furnace is always turning off, it can result in unnecessary work and stress on your system that could lead to more expensive repairs or even a replacement.
