But as with every appliance in your home, a gas furnace can experience problems. Before trouble crops up, there are some things you can do to maintain the unit.


  • Replace your furnace filter on a monthly basis. If you choose to use reusable filters, vacuum them monthly.
  • Vacuum and brush the heat exchanger yearly.
  • Check your ductwork for leaks, and if you find any tears wrap them with duct tape.
  • Consult your owners manual to see if your units fan and fan motors needs yearly oiling.
  • Put a carbon monoxide detector near your furnace in order to alert you in case a leak occurs.
  • If you choose not to perform these maintenance tasks yourself, make sure you call a professional. It is imperative that maintenance is done to extend the life of your unit.


If trouble arises, here are some steps you can take.

  • First of all, if you smell gas DO NOT try and fix it yourself. Call a professional immediately. Open your windows, get out of the house, and make sure your children and pets are with you. Do not turn on any lights or switches, and call the gas company from either your cell phone outside the home or your neighbors house. Stay out of the house until it has been deemed safe after a professional examination.

If heat is not coming from the vents:

  • Make sure the pilot light is lit. You may need to re-light it, so be very careful. Make sure the thermostat is set to heat and set that temperature at least three degrees higher than room temperature. This should start the furnace.
  • Check the fuse box to make sure that no breakers a flipped in the wrong direction or that a fuse has not blown. If necessary, reset the breaker or change the fuse.
  • Reset the blower motor. If it does not start right away, that might be because it overheated. Wait five minutes or so and try resetting it again.
  • If none of these steps work, call a technician.

If not enough heat is being emitted:

  • Make sure the thermostat is set to the correct temperature.
  • Make sure the heating registers are open and unobstructed.
  • Check the filter and replace it immediately if it is dirty.
  • Call an HVAC professional to check the system if none of these steps work.

If the motor is running yet no air is moving:

  • Check the belt that connects the motor to the blower. If it is broken, you can try to replace it (make sure you check the owners manual). If you don’t feel confident, call an HVAC technician.
