Completed AC cool check on two systems. Both drain lines have been flushed and treated. Both condenser coils have been cleaned. I found the upstairs outdoor torque booster out of manufacturer specs. I went over my findings and presented repair options to the homeowner and he decided to move forward with replacement of torque booster today. I replaced the torque booster and function checked the system. No other major issues were found. Both systems are cooling at completion of service.
