Why Does My Furnace Keep Shutting Off?

There is usually a sense of anxiety when you notice something isn’t quite right with your furnace. You’re resting at home and you notice your furnace is continuously kicking in and shutting off. However, before you panic, there are several items 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 air filters also work to keep your system clean. Your first step when you recognize a concern with your system should be checking your air filter to see if it needs replacement. If it’s clogged or dirty, it can make it difficult 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, especially when using a smart or programmable thermostat. Examine your thermostat to see if anything unusual 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 typically hotter than the rest of your house, 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 appropriate insulation, your furnace is likely to shut off more regularly. Walk around your home and check the windows to confirm they are all closed and examine the seals around your windows for any drafts or cold air coming into the house.

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