Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is usually a sense of dread when you recognize something isn’t quite right with your furnace. You’re sitting at home and you hear your furnace is endlessly kicking in and shutting off. However, before you panic, there are a few 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 they also support keeping your system clean. Your first step when you notice an issue with your system should be taking a look at your air filter to see if it should 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 lots 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 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 by another heat source, it could be mistakenly assuming your home reached the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have proper insulation, your furnace is likely to shut off more regularly. Walk around your home and check the windows to make sure 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 by 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 expensive repairs or even a replacement.
