    What to do if my Garrison 2498549 Heat Pump is not cooling or heating the room?
    • J
      Jeremy RoweAug 9, 2025
      If your Garrison Heat Pump isn't cooling or heating the room effectively, ensure that curtains, blinds, and furniture aren't blocking the unit's airflow. Try adjusting the temperature setting to be lower or higher. Also, clean the filters. Allow enough time for the unit to heat or cool the room, or start it early. Ensure the vent door is closed and check the dip switch and wall thermostat settings. Note that it may take around 3 minutes for the compressor to start.

      If your Garrison Heat Pump isn't starting, check that the plug is securely plugged into the wall receptacle and that the plug has not tripped (it has a test/reset button). Also, replace the fuse or reset the circuit breaker. Finally, make sure the unit is turned on using the bottom right button on the keypad.

      Martin VanceAug 31, 2025
      If water is dripping inside from your Garrison Heat Pump, it might be because the wall sleeve isn't installed level. The wall sleeve must be level to ensure proper condensation drainage. Check the installation and adjust as necessary.
