Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of dread when you notice something isn’t quite right with your furnace. You’re sitting at home and you notice your furnace is endlessly kicking in and shutting off. However, before you panic, there are some things you can check when you first notice that your furnace seems to be shutting off more frequently 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 a problem with your system should be checking your air filter to see if it should be replaced. If it’s clogged or dirty, it can make it tough for air to flow over the heat exchanger.
  2. Look at your thermostat—For lots of us, we may have set our thermostats several months ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything strange is going on or if it might 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 home, such as in direct sunlight or near another heat source, it could be wrongly 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 often. 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 entering the home.

While you can look at these issues on your own, 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 end up forcing unnecessary work and stress on your system that could lead to more costly repairs or even a replacement.
