Heating Troubleshooting

Is your heat not working? Is your fan blowing and warm air not coming from your vents? There are a few things you can check to see if you have a problem with your heat. Need help? Learn more about heat and how we can get you up and going!

I Have No Heat

Your gas could be turned off.

  • Recommended action: Check gas valve at gas company meter, check shutoff valve at furnace, and check for other shutoff valves. Contact the gas company to have the gas valve turned on or contact your Ronald Smith Heating & Air service department.

Your system could be turned off or your unit unplugged.

  • Recommended action: Check your thermostat and heating unit to assure that they are both plugged in. Refer to your use and care guide or contact our heating professionals.

Your thermostat may be off or set incorrectly.

  • Recommended action: Make sure your thermostat is on and set to heat. If the thermostat is on, reset the thermostat to your desired temperature.

You may have a tripped circuit breaker.

  • Recommended action: Check your home circuit breaker box and reset the circuit breaker.

I Have No Airflow

You may have dirty filters.

  • Recommended action: Check the filters in each of your system's components. Clean or replace filters as recommended in your use and care guide. If the problem persists, please contact our Lithia Springs heating service specialists.

Your system may have frozen up due to a dirty coil.

  • Recommended action: Check for signs of water below the unit and cold exterior surface of indoor coil enclosure. Contact your Ronald Smith Heating & Air service department. In the meantime, try turning your thermostat off for 1 to 3 hours to see if it will defrost.

My Utility Bill Is Unusually High

If your system is reaching its set point, is it working correctly? Have your local temperatures been extreme lately?

  • Recommended action: Check the following: Is your system cycling constantly? Is your thermostat reaching its set value? Do you have any new appliances (e.g., a hot tub or pool heater) that use lots of power? Have you checked to see if your local utility company had a recent rate increase? If your system is not reaching its set point, please contact us today.

My System Is Constantly Running

Your system could be trying to reach a set point that is too extreme.

  • Recommended action: Check the set point on your thermostat. Is it very low (in summer months) or very high (in winter months)? First, reset your thermostat. If that doesn’t work, please contact us as soon as possible.

My Drain Pan Is Overflowing

The overflow switch is probably not working.

  • Recommended action: Turn off your system and contact our heating experts for a fast and effective solution.

My System Is Malfunctioning

Check any of the above troubleshooting issues for help.

  • Recommended action: If none of the troubleshooting answers address your problem, then turn off your system and contact your Ronald Smith Heating & Air service department.
