No Heat Checklist

Boiler, Furnace, or Heating System Trouble-Shooting Checklist

Link Mechanical Services receives dozens of phone calls each year from homeowners who are having problems with their furnaces. They often ask if there is something they can do before having to schedule a furnace repair.

If your furnace isn't producing enough heat or it is not switching on when it should follow this trouble-shooting checklist:

Natural Gas Furnaces and Boilers:

  • Ensure that the thermostat is set in the heating mode and that the temperature is set above the room temperature (3-5 degrees higher).
  • If your thermostat is battery operated check that your batteries are charged.
  • If your furnace is a forced air system, check the thermostat switch for "fan;" it should be in the "ON" position.
  • Verify that your filter is clean (forced air systems).
  • Make sure all vents and return air ducts are open and not blocked (forced air systems).
  • Check the emergency switch at the top of the cellar stairs to make sure it is in the "on" position.
  • Check the service switch on the side of the furnace to make sure it is the "ON" position.
  • Check to see if any circuit breakers are tripped in the electrical panel. Reset if needed.
  • If you have a standing pilot model gas burner make sure the pilot is lit. Re-light if needed.
  • Make sure your gas meter is on and service has not been interrupted.
  • Check to make sure the flue vents are not blocked on high efficiency systems. Clear away any snow or ice.
  • JUST CALL LINK for service if this does not get your system up and running.

Oil / Propane / LP Gas Furnaces and Boilers:

For Propane or Oil Furnaces and Boilers follow the steps listed above plus these:

  • Make sure your fuel tank has fuel in it. Low tank levels and cold weather can cause intermittent problems.
  • JUST CALL LINK for service if this does not get your system up and running.

If Your Furnace is Having any of the Following Problems Call for Service Right Away:

  • You notice fluid or water leaking around the furnace or humidifier.
  • Your furnace is making strange noises or is noisier than usual.
  • You furnace has a hard time starting up, takes longer than usual to get started, or you notice your lights dim upon start up.
  • Your furnace runs continually.
