Why Does My Furnace Keep Shutting Off?

There is typically a sense of dread when you notice 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 several items you can check when you realize 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 air filters also help 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 needs replacement. If it’s clogged or dirty, it can make it hard for air to flow over the heat exchanger.
2. Look at your thermostat—For lots of us, we may have set our thermostats several months ago and forgot about it, especially when using a smart or programmable thermostat. Look at your thermostat to see if anything unfamiliar is occurring 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 typically hotter than the rest of your space, such as in direct sunlight or by 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 proper 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 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 lead to unnecessary work and stress on your system that could cause more expensive repairs or even a replacement.
