Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dismay when you recognize 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 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 air in your house cleaner, but they also support keeping your system clean. Your first step when you recognize an issue 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 difficult for air to flow over the heat exchanger.
  2. Look at your thermostat—For many of us, we may have set our thermostats weeks ago and forgot about it, particularly when using a smart or programmable thermostat. Check your thermostat to see if anything unusual is taking place 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 house, such as in direct sunlight or close to 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 appropriate 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 inspect the seals around your windows for any drafts or cold air entering into your house.

While you can look at these issues 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 pricey repairs or even a replacement.
