HVAC Troubleshooting for Heat Pumps

Heat pump won’t turn on

  • Check the thermostat to make sure settings are correct (heat when heat is required, cool when air conditioning is required). Set the temperature either a few degrees higher than room temperature for heating or a few degrees lower for cooling, which should initiate a heat pump cycle.
  • Check power sources to the thermostat. Change batteries if battery-powered. If hardwired, check the circuit breaker box. Is the breaker powering the thermostat tripped?
  • Check power sources to the heat pump. Check the on/off switches located near your indoor and outdoor units. Have they accidentally flipped? Finally, check the home’s circuit breaker panel. Is the breaker powering the heat pump flipped?

Heat pump isn’t producing enough heating/cooling

  • Make sure all registers throughout the home are open and all vents unblocked.
  • Check your air filter. Change it if it’s clogged and restricts airflow.

Heat pump freezes up

  • If the heat pump’s defrost cycle is not melting ice accumulated on the unit, turn off the system for HVAC troubleshooting.
  • Check the air filter for clogs and replace it if needed.
  • Inspect air vents throughout the home and make sure they are not closed or blocked.
  • Try to gently remove any ice built up on the coil. Do not use tools which could damage the unit.
  • Pour warm water slowly over the ice to melt it.
  • If gutters above the unit are allowing water to empty onto your heat pump, reroute the flow of water away from your heat pump.

Heat pump makes loud noises during operation

  • Loose cover panels often cause rattling noises during operation. Check all panels to the unit. Securely tighten all screws.
  • Inspect ductwork if possible for loose sections which may cause noise during operation. You may be able to seal or tighten these sections yourself, or call Douglas Cooling & Heating for professional HVAC troubleshooting.
