Why Does My Furnace Keep Shutting Off?

There is usually a sense of dread when you notice something isn’t quite right with your furnace. You’re sitting at home and you realize your furnace is endlessly kicking in and shutting off. However, before you panic, there are several items you can check when you feel like 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 air in your house cleaner, but air filters also work to keep your system clean. Your first step when you recognize a problem 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 tough for air to flow over the heat exchanger.
  2. 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. Examine your thermostat to see if anything strange is occurring or if it might need new batteries. The placement 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 near another heat source, it could be mistakenly 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 frequently. Walk around your home and check the windows to confirm they are all closed and examine the seals around your windows for any drafts or cold air entering into your house.

While you can review these issues by yourself, if issues still persist after these checks, it might be time to call in the experts. When your furnace is consistently turning off, it can result in unnecessary work and stress on your system that could cause more pricey repairs or even a replacement.
