Heating your Newtown, PA, home should be as simple as switching on the furnace and choosing an ideal temperature on the thermostat. However, if your furnace runs non-stop, there’s an issue that requires attention. Learn more about the possible causes of a constantly running furnace and when to call a professional for help.
Fan Is Set to On
You have an option on the thermostat that allows the fan in your furnace to run constantly. If your system continues to run at all times, first check the thermostat and make sure the fan is in the auto position rather than on.
Temperature Setting Is Too High
If your furnace just runs and runs without a break, check the temperature setting on your thermostat. If your temperature setting is too high, your system may continue to operate and may not ever reach that set temperature due to the conditions outdoors. Lower the temperature, and see if that helps the issue.
Dirty Filters
Dirty furnace filters make it harder for your furnace to push hot air through the system. As part of regular HVAC maintenance, change your filters at least once every three months. If your furnace is running non-stop, check your filters to make sure they aren’t adding stress and strain to the system.
Blower Issue
If your furnace’s blower is malfunctioning, it may run without stopping. If you’ve checked the other troubleshooting tips above and have not found a solution, you may need to call us so that we can perform an inspection.
System Is Too Small
The size of your furnace determines how much space it can reasonably heat. If you’ve added on to your home or made other changes, it could affect the furnace’s ability to heat your home. It’s also possible that your system was simply not sized properly before it was installed. If your system is too small, it may continue to run without stopping as it attempts to reach your desired temperature.
