Why Does My Furnace Keep Shutting Off?

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 notice your furnace is endlessly 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 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 inside your home cleaner, but air filters also work to keep your system clean. Your first step when you notice a problem with your system should be examining 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 several of us, we may have set our thermostats months ago and forgot about it, especially 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 location 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 house, such as in direct sunlight or close to another heat source, it could be falsely assuming your home reached 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 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 coming into the house.

While you can look at these issues yourself, if issues still persist after these checks, it might be time to call in the professionals. When your furnace is always turning off, it can lead to unnecessary work and stress on your system that could lead to more pricey repairs or even a replacement.
