Performed diagnostic on 5 year old unit. System is not cooling. Found outdoor compressor not turning on. Checked outdoor unit electrical and system components. Found a bad secondary motor control keeping the compressor from turning on. Replaced secondary motor control, compressor kicked on and system started cooling. Refrigerant pressures and amp draws are within range. Temperature split is good. Filter needs to be replaced, did not have size on my van and homeowner will be replacing it himself. Went over adding surge Protection to unit as well as the maintenance program. Wants to hold off on any other work for today. Cycled system, system is operational upon departure.
