Winter Heat Pump Troubleshooting

If the temperature has dropped outdoors and your heat pump is not warming up your home, you may be facing a heating problem. But is it something you need to call your local HVAC service company to repair? Before you make a service call, do a little troubleshooting to see if it is something as simple as a blown fuse. Here are a few troubleshooting tips for a heat pump that is not heating your home.

  • Check the thermostat. Begin your troubleshooting at the thermostat to check where the temperature is set. Try moving it up a few degrees above the current temp to see if the unit turns on and whether it blows hot air.
  • Turn the fan on. If the fan does not come on, it could be a blown fuse. If the breaker is tripped, you may have a blown blower motor, bad wiring or the control board. If the breaker is not tripped, it may be the fan relay or the thermostat.
  • Check the heat. If the fan turns on, switch to emergency heat. If the unit blows warm air, the problem is most likely with the outside unit. If the fan is on but there is no heat, the thermostat may need to be replaced or it could be in your air handler.

If it is not something as simple as the thermostat being set incorrectly or a blown fuse, you will most likely need to call your local HVAC service company to fix the issue. Keep in mind that regular heat pump maintenance and inspections can help reduce emergency repairs and catch problems before they start and you are left in the cold.
