Why Does My Furnace Keep Shutting Off?

There is usually a sense of dismay when you realize something isn’t quite right with your furnace. You’re resting at home and you realize 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 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 indoor air cleaner, but they also support keeping your system clean. Your first step when you realize there is 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 lots of us, we may have set our thermostats weeks ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything unfamiliar 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 usually hotter than the rest of your house, such as in direct sunlight or by another heat source, it could be wrongly assuming your home is already up to the desired temperature.
  3. Check out your windows for proper insulation—If your home doesn’t have the right 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 examine the seals around your windows for any drafts or cold air coming into the house.

While you can review these issues on your own, if issues still continue after these checks, it might be time to call in the professionals. When your furnace is consistently turning off, it can result in unnecessary work and stress on your system that could cause more pricey repairs or even a replacement.
