Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is typically a sense of dismay when you recognize something isn’t quite right with your furnace. You’re relaxing at home and you hear your furnace is continuously kicking in and shutting off. However, before you panic, there are some things you can check when you realize 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 the filters also support keeping your system clean. Your first step when you recognize a concern with your system should be examining your air filter to see if it should 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 several of us, we may have set our thermostats weeks ago and forgot about it, especially when using a smart or programmable thermostat. Look at your thermostat to see if anything unusual is taking place 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 house, such as in direct sunlight or by another heat source, it could be falsely assuming your home has met 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 ensure they are all closed and inspect 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 occur 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 produce more pricey repairs or even a replacement.
