Having Furnace Trouble? Check These Things First

A few times each fall we get calls from our customers here in the Kennesaw and Greater Atlanta area that are having furnace issues, and once we get to their home and check out the system, we find all that was needed was a very simple fix. If you want to save some time and money, there are a few things you can do as a prudent home or business owner to see if you can't solve your furnace issue without professional help.

Of course there are definitely times when a repair or maintenance issue will have to be handled by expert technicians, but check these things the next time you are having furnace trouble:

  • Take A Look At Your Thermostat
    • We know it sounds simple, but sometimes your thermostat is off. Double check it to make sure it's on and set to heating, to a temperature that is above the current room temperature.
    • Faulty batteries can also cause your thermostat to not fire, change your batteries and restart your thermostat.
  • System Power
    • Your furnace switch could have been accidentally switched off - go to your system and find the on/off switch which sometimes has a red cover plate, if this is off turn it on.
    • If the problem wasn't the system switch, your breaker could have tripped. Find your homes circuit breaker panel, and switch the furnace breaker to on.
  • Gas Supply
    • There is a chance you could be out of fuel, find your storage tank and make sure you have natural gas or LP available.
  • Airflow
    • There could be something obstructing the air registers for your system, double check that these are free and clear of debris.
    • Finally, Change your furnace filter and re-start your furnace.

If you went through all of the above steps and your system is still having issues, you likely need some professional service help. That's where we come in! Call us to get the professional furnace repair help you need in the Kennesaw and Atlanta area.

  • A failed component like a transformer, furnace control, or inducer motor.

Furnace tries to start, but either fails to fire, or fire drops out shortly after lighting:

  • An obstructed vent system.
  • Improper grounding or incorrect gas pressure.
  • Problem with the burners, heat exchanger, or flame safety system.

The furnace system runs ok, but needs to be restarted every once in a while.

  • Problem with the thermostat or thermostat batteries.
  • Problem with the flame safety components, gas valve or gas pressure, or the heat exchanger.

Furnace runs, but something seems to be ineffective:

  • Dirty filters and lack of maintenance. This would cause inconsistent temperature or wide temperature swings, unusual blower noise, or rapid furnace cycling.
