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 notice 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 inside your home cleaner, but the filters also help keep your system clean. Your first step when you notice a problem with your system should be checking your air filter to see if it needs replacement. 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, especially when using a smart or programmable thermostat. Examine your thermostat to see if anything unusual is occurring or if it may need new batteries. The site of your thermostat could make a difference, as well. If it’s located in a place that’s often hotter than the rest of your space, such as in direct sunlight or near 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 proper insulation, your furnace is likely to shut off more frequently. Walk around your home and check the windows to make sure they are all closed and take a look at the seals around your windows for any drafts or cold air entering the home.

While you can review these issues on your own, if issues still occur after these checks, it might be time to call in the professionals. When your furnace is always turning off, it can end up forcing unnecessary work and stress on your system that could produce more expensive repairs or even a replacement.
