Troubleshooting Checklist: No Heat

If you’re having trouble with your furnace, heat pump or heating system, you can always call our offices for help and service. However, here are a few simple suggestions to try before setting up a service appointment.


  • Check to make sure that the thermostat is set in the HEAT position.
  • Make sure that the temperature setting on the thermostat is set HIGHER than the current indoor temperature.
  • Ensure that there’s power to the furnace:
    • Try turning the fan to “ON” on the thermostat to test for power to furnace.
    • If no action, reset the breakers at the electrical panel, especially if the thermostat is showing a blank reading.
  • Is there any air coming out of your vents?
    • Always make sure you routinely change out your filters as directed to ensure peak performance.
    • In addition, check all return air grilles and registers. Make sure they are not blocked by furniture and are open and blowing air.
