A Problem With Your Heat Pump? Try Some Easy Troubleshooting Before You Call For Help

Last updated 1 year ago

A heat pump provides efficient heating and cooling for your San Fernando or Santa Clarita Valley home, but if your heat pump is having operating issues, it could leave you without the cool air you need this summer. 

Consider these easy summertime troubleshooting tips before you call for help.

Heat pump won’t turn on

  • Make sure the thermostat is set below the room temperature and set to “cool.”
  • Check the main electrical panel along with sub-panels that could have a tripped circuit breaker. Reset any tripped breakers you find.
  • If a power switch is used to control the heat pump, make sure it’s turned on.

Heat pump won’t cool properly

  • Check the thermostat setting. Lower the temperature a few degrees and wait a few minutes to see if the system will come on.
  • Make sure supply and return registers are open and not blocked by furniture or other obstructions.
  • Clean or change the air filter.
  • Clean the outdoor condensing unit’s coils.

Heat pump cycles are too frequent

  • The unit could be overheating. Clean or replace the filter to see if that makes a difference.
  • If your thermostat was installed recently, it could be incorrectly calibrated or installed in a location that doesn’t receive an accurate air sample. Contact a technician if changing the filter doesn’t help.

Heat pump blower won’t work

  • Check the thermostat. If the fan switch is set to “off” or “auto” but the blower still won’t work, the limit switch likely needs to be adjusted. You should leave this task to a technician.
  • If the motor runs but air doesn’t move, the belt is probably broken. Again, you should leave the job to a qualified technician.

Heat pump makes loud noises

  • Rattling noises could mean that the cover panels are loose. Tighten the screws on the indoor unit's panels to see if the noise stops.
  • Squealing or grinding noises indicate that the motor bearings are probably shot. Turn off the heat pump and call a technician.

With these troubleshooting tips, you know what problems are easy to handle and what you should leave to a professional. Contact Pacific Aire Heating & Cooling in the San Fernando and Santa Clarita Valley areas for help if these troubleshooting tips don't address the problem.
