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.
