What to do if my Garrison Heat Pump is not cooling or heating the room?

  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.
