From what I remember them saying the wire was one size to small, they couldnt fit the 3 or however many wires they put in at the proper gauge. I remember they had a hard time pulling the wires. Maybe they used 2-12ga on a 3 ton and about 65-70ft of run, It rattles inside , ive checked the sound at the pipe, thats how I can also tell its cycling on. Well the tech came out and disconnected the timer that was needed for my old round analog Honywell and he said it was empty on freon. They fixed a leak about 3 weeks ago so he did the call for free. Well now I have another leak, I will just wait to see what happens, maybe I can avoid any more repairs this year, the date on the unit was 1994.
