For this job, Technicians arrived to the system blowing like warm air and the heat pump was not making the indoor coil hot. All amperage’s looked good after shutting system down to check some wiring the system fired up and ran perfectly after powered back up. Technician checked to make sure that when the system has more then 5 to 10 degrees to rise that the back up heat will kick in to help, the strips did kick in. Technician checked system for proper operation and is running great at this time.
