Heating System Troubleshooting
Trouble-Shooting: Boiler, Furnace, or Heating System Problems
Natural Gas Furnaces and Boilers:
- Thermostat: Check settings. It should be set for 'heat' and the temperature set at least 3-5 degrees higher than the current room temperature.
- Thermostat Battery: Check to ensure operation. Replace if needed.
- Filter: Clean and Replace if Needed
- Thermostat Switch: For forced air furnaces the thermostat switch for "fan;" is in the "ON" position.
- Vents & Return Air Ducts: Check to ensure they are open and not blocked (forced air systems).
- Service Switch: Ensure it is in the 'on' position.
- Electrical Panel: Check Circuit Breakers. Reset any tripped breakers.
- Pilot Light: If you have a standing pilot model gas burner make sure the pilot is lit.
- Gas Meter: Make sure your gas meter is on, and service has not been interrupted.
- Flue: Check to make sure the flue vents are not blocked on high-efficiency systems. Clear away any snow or ice.
Oil / Propane / LP Gas Furnaces and Boilers:
Repeat the steps listed above plus:
- Fuel Level: Ensure you have enough fuel. Low fuel levels and cold weather can cause intermittent problems.

- Water Leaking (Standing Water Anywhere Around the Unit)
- Making Strange Noises
