Arrived to find the system set in the off position. Customer stated the indoor unit would not run but the outdoor unit would run. During diagnosis of the system, I found a faulty fan relay switch. I also found the indoor torque booster well below manufacturer specs. I went over repair options with the homeowner and they chose to replace the fan relay and indoor torque booster. I completed the repairs and the torque booster and relay switch were replaced. The system was cooling at time of departure.
