Why does my furnace keep shutting off? Published on September 15, 2017 There is always a sense of dismay when you recognize something isn’t quite right with your furnace. You’re sitting 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 first notice that 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 notice a concern with your system should be examining 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. Look at your thermostat—For several of us, we may have set our thermostats several months ago and forgot about it, particularly when using a smart or programmable thermostat. Look at your thermostat to see if anything unfamiliar is taking place 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 typically hotter than the rest of your space, such as in direct sunlight or near another heat source, it could be wrongly assuming your home has met the desired temperature. Check out your windows for proper insulation—If your home doesn’t have proper insulation, your furnace is likely to shut off more often. Walk around your home and check the windows to confirm they are all closed and take a look at the seals around your windows for any drafts or cold air entering the home. While you can review these issues by yourself, if issues still occur 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 produce more pricey repairs or even a replacement.
