Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dismay when you notice something isn’t quite right with your furnace. You’re resting 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 air in your house cleaner, but air filters also work to keep your system clean. Your first step when you realize there is 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 hard for air to flow over the heat exchanger.
  2. Look at your thermostat—For several of us, we may have set our thermostats several months ago and forgot about it, especially when using a smart or programmable thermostat. Examine your thermostat to see if anything unfamiliar 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 usually hotter than the rest of your home, such as in direct sunlight or near another heat source, it could be mistakenly assuming your home is already up to 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 take a look at the seals around your windows for any drafts or cold air entering into your house.

While you can review these issues yourself, if issues still continue after these checks, it might be time to call in the experts. When your furnace is consistently turning off, it can result in unnecessary work and stress on your system that could lead to more expensive repairs or even a replacement.
