Heat Pump Troubleshooting Steps Before Calling a Professional

Before phoning a professional HVAC service provider to diagnose and correct problems with your heat pump, there are several steps you can take to identify why your heat pump is stuck in heating or cooling mode:

  • Check the thermostat settings: Confirm your thermostat is in the correct mode. If you have a programmable thermostat, double check the setpoint and schedule.
  • Look at the circuit breakers. Confirm the circuit breakers for the heat pump and the air handler/furnace are in the right position. Occasionally a tripped breaker can stop the heat pump from functioning correctly. 
  • Assess airflow and filters: Poor airflow caused by dirty filters, blocked vents or other obstructions can lead to inefficient operation. Replace dirty air filters for clean ones and make sure the vents or registers are open and not covered by furniture, rugs or other items that could reduce airflow.
  • Look at the outdoor unit: Check the outdoor unit and condenser for waste, dirt or plant life that might be limiting airflow. Remove any debris that might impair the unit’s performance.

When to Contact a Professional for Heat Pump Problems

While some heat pump issues can be simply solved by homeowners, sometimes it’s better to turn to a professional for support. For instance, if you have questions about the power supply to your heat pump, it’s safer to call a professional.

Heat pumps may be stuck in heating or cooling mode for numerous reasons that require technical expertise, such as improper refrigerant levels or problems with temperature sensors or valves. If one of those problems is causing your heat pump to malfunction, it’s best to have it fixed by an experienced professional like you find on the team at Bryant Heating & Cooling Service Experts.
