Why Does My Furnace Keep Shutting Off?

There is typically a sense of anxiety 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 a few things you can check when you feel like 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 indoor air cleaner, but air 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 many of us, we may have set our thermostats weeks ago and forgot about it, even more so when using a smart or programmable thermostat. Look at your thermostat to see if anything unfamiliar is going on or if it could 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 home, 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 ensure 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 yourself, if issues still persist after these checks, it might be time to call in the experts. When your furnace is always turning off, it can lead to unnecessary work and stress on your system that could lead to more pricey repairs or even a replacement.
