Why Does My Furnace Keep Shutting Off?

September 15, 2017

There is always a sense of anxiety when you notice something isn’t quite right with your furnace. You’re resting at home and you hear your furnace is endlessly kicking in and shutting off. However, before you panic, there are several items 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 indoor air cleaner, but they also help 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 difficult 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, even more so when using a smart or programmable thermostat. Look at your thermostat to see if anything unfamiliar is taking place or if it could 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 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 appropriate 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 inspect the seals around your windows for any drafts or cold air entering into your house.

While you can certainly check for some of these issues on your own, if issues still occur after these checks, it might be time to call in the pros. When your furnace is consistently turning off, it can result in unnecessary work and stress on your system that could produce more costly repairs or even a replacement.
