AC cool check completed on one horizontal Carrier system. Drain line was flushed. Condenser coils were cleaned. I found the blower wheel with some buildup. I also found the outdoor torque booster below manufacturer specs. I went over my findings and presented options for repair and the homeowner chose to replace the torque booster at this time. I completed the repair and function checked the system. No other major issues were found. The system was cooling properly at time of departure.
