On this job I looked at 2 system. Both test in tolerance on the cooling side. TD is 20. The subcool is 9°. Both systems now have clean filters and both condensors are washed. I do recommend easy starts for both systems. The trane compressor although functional has a large amount of heat stress on his head. The easy start can help take the edge of this system for sure by lowering inrush amps by 75%.
