AC cooling maintenance completed on one vertical Carrier system. Drain line was flushed and treated. Condenser coils were cleaned. I found the outdoor torque booster below manufacturer specs. I also found the condenser fan motor showing signs of overheating. I went over my findings and presented repair options to Kathy. She chose to replace the torque booster and condenser fan motor at this visit. I completed the repairs and cycled the system to check proper operation. No other major issues were found. The system is cooling properly at time of departure.
