I went to check a unit today and there where alot of problems. the one that make me think the most about the unit is the fact that I went to pump the compressor down and when I got it pumped down i killed the power and watched the gauges. the low and high start to equalize and over about 20 min. the system had equalize. This is telling me that the valves are bad. Have not heard what the boss had told them but this is my first thoughs. Any ideas?
Am I on the right track?
