Is Your Thermostat Ready?


  • Verify that your thermostat is set in the HEAT position.

  • Does the temperature setting on the thermostat exceed the thermostat's indoor temperature?

Is Everything On?

  • Is your furnace’s power turned on?

  • At the thermostat, set the fan to the ON position. The fan should continue running when the power is being supplied to the furnace.

  • Check to see if the circuit breakers in the circuit breaker box (or electrical panel) are tripped to the OFF position.

  • Verify that the SSU light switch on the gray box located at the furnace is in the ON position.

Is There Proper Airflow?

  • Have you changed your filter?

  • A dirty filter can cause unit shutdowns due to insufficient airflow.

  • Check to see if the air registers (supply or return ducts) are plugged, blocked, or closed.

Troubleshooting Your Residential Heating System


Maintaining a comfortable and warm home during the colder months is crucial. If you find that your heating system isn't performing as expected, follow these troubleshooting steps for different types of residential heating units:

Troubleshooting a Gas Heating Unit

1. No Heat:

  • Check the thermostat settings to ensure it's set to "Heat" and the temperature is higher than the current room temperature.

2. Pilot Light:

  • If you have a pilot light, make sure it's lit. If not, follow your unit's manual to relight it safely.

3. Gas Supply:

  • Verify that the gas supply valve is open. If closed, open it, but if you smell gas, leave your home immediately and call your gas company.

4. Air Filter:

  • A clogged or dirty air filter can restrict airflow. Replace it regularly (usually every 1-3 months) for efficient heating.

Troubleshooting an Electric Heating Unit

1. No Heat:

  • Confirm that the thermostat is set to "Heat" and the temperature is higher than the room's current temperature.

2. Circuit Breaker:

  • Check the circuit breaker for the heating unit. If it's tripped, reset it. If it keeps tripping, consult an electrician.

3. Heating Elements:

  • Examine the heating elements for signs of damage or wear. If you notice issues, contact a technician for repairs.

4. Thermostat Calibration:

  • Ensure your thermostat is calibrated correctly. Inaccurate calibration can lead to temperature discrepancies.

Troubleshooting a Heat Pump Heating Unit

1. Insufficient Heating:

  • Verify that the thermostat is set to "Heat" and the desired temperature is higher than the current room temperature.

2. Clean Filters:

  • Clean or replace the filters regularly to maintain airflow. Clogged filters can reduce efficiency.

3. Outdoor Unit:

  • Clear any debris or snow from the outdoor unit. Obstructions can hinder the heat pump's operation.

4. Refrigerant Levels:

  • Low refrigerant levels can impact heating. If you suspect a leak, contact a professional technician for inspection.

Troubleshooting a Geothermal Heating Unit

1. Insufficient Heating:

  • Ensure the thermostat settings are correct and set to "Heat."

2. Check the Loop System:

  • Geothermal systems use a loop buried underground. Check for any damage to the loop or leaks.

3. Pump Operation:

  • Verify that the circulation pump is working correctly. It should circulate water through the system.

4. Professional Inspection:

  • Geothermal systems can be complex. If issues persist, consult a geothermal HVAC technician for a thorough inspection.

Remember to prioritize safety when troubleshooting your heating unit. Turn off power to the unit before conducting any maintenance, and if you're uncertain about any steps or encounter gas odors, leave your home and contact professionals immediately. Regular maintenance can help prevent many common issues, so consider scheduling annual maintenance checks for your heating system to keep your home cozy during the colder seasons.
