Why Does My Furnace Keep Shutting Off?

There is always a sense of dismay when you realize something isn’t quite right with your furnace. You’re resting at home and you hear your furnace is continuously kicking in and shutting off. However, before you panic, there are some 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 the filters also work to keep your system clean. Your first step when you realize there is an issue 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 difficult for air to flow over the heat exchanger.
2. Look at your thermostat—For several of us, we may have set our thermostats several months ago and forgot about it, even more so when using a smart or programmable thermostat. Examine your thermostat to see if anything strange 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 often hotter than the rest of your space, such as in direct sunlight or near another heat source, it could be falsely 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 regularly. Walk around your home and check the windows to ensure they are all closed and take a look at the seals around your windows for any drafts or cold air coming into the house.

While you can certainly check for some of these issues by yourself, if issues still continue 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 cause more expensive repairs or even a replacement.
