Heat check completed on a horizontal heat pump system. Drain line was flushed and treated. Condenser coils were cleaned. All electrical and mechanical components were checked. I did find a failing torque booster on the heat pump. I also found an oversized breaker on the heat pump. I spoke with the homeowners about repair options. They chose to replace the outdoor torque booster today. I completed the repair and function tested the system. The system is heating properly at time of departure.
