The winter months in and around Nashville, TN, can produce temperatures in the low teens, bringing the need for every homeowner to start focusing on their furnace. When your furnace runs continuously even after reaching the target thermostat temperature, it probably means something is wrong with your heating system. Here are three possible reasons that may trigger your furnace to run constantly.

1. Faulty Air Filters

Over time, dust and debris will clog your filter, affecting the airflow and making your furnace work harder to maintain the desired temperature for your Nashville home. Routine maintenance from a top heating company like Busy Bee Heating & Air Conditioning will help stop this problem.

2. Incorrect Thermostat Setting

If your filters are well, it’s time to check the fan setting on your thermostat. If it’s set to ON, the furnace’s fan will constantly run no matter what the temperature is. You need to change this setting to AUTO so that when the furnace is on, the blower operates.

3. Temperature Setting Is Too High

Setting the temperature too high on your thermostat can be another reason your heating system is running continuously. Reduce the temperature setting to the desired levels and observe if the furnace cycles off. Sometimes the heating system will run constantly to keep up with the set temperature, especially if it’s cold outside.

4. Malfunctioning Pilot Light

Most old furnaces have a built-in pilot light that should remain on throughout the cold season. If it fails to light, you may discover your furnace is constantly running and blowing cold air. You can follow the manufacturer’s instructions to relight the pilot light.

If none of the above suggestions fixes your furnace issues, it’s time to look for professional HVAC help. Contact Busy Bee Heating & Air Conditioning today to schedule an appointment, and our experienced HVAC technicians will help you with all your furnace needs.
