Why does my furnace keep shutting off? Published on September 15, 2017 There is always a sense of anxiety when you recognize something isn’t quite right with your furnace. You’re relaxing at home and you hear your furnace is endlessly 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 frequently than it should be. 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 they also work to keep your system clean. Your first step when you realize there is a concern 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 hard for air to flow over the heat exchanger. Look at your thermostat—For many of us, we may have set our thermostats months ago and forgot about it, especially when using a smart or programmable thermostat. Check your thermostat to see if anything unusual is taking place or if it may 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 space, such as in direct sunlight or close to another heat source, it could be falsely assuming your home reached the desired temperature. Check out your windows for proper insulation—If your home doesn’t have the right 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 inspect the seals around your windows for any drafts or cold air entering the home. While you can review these issues yourself, if issues still persist after these checks, it might be time to call in the professionals. When your furnace is consistently turning off, it can end up forcing unnecessary work and stress on your system that could lead to more pricey repairs or even a replacement.
