Why Does My Furnace Keep Shutting Off?

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 constantly kicking in and shutting off. However, before you panic, there are a few things you can check when you feel like your furnace seems to be shutting off more than usual 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 they also help keep your system clean. Your first step when you recognize a problem 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 tough 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, particularly when using a smart or programmable thermostat. Check your thermostat to see if anything unusual is going on 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 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 appropriate insulation, your furnace is likely to shut off more frequently. Walk around your home and check the windows to confirm they are all closed and examine the seals around your windows for any drafts or cold air entering into your house.

While you can look at these issues yourself, if issues still persist 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 cause more costly repairs or even a replacement.
