My salon Ac unit bit the dust. It worked perfect during survey and seatrial and quit during the delivery. The AC guy says the motor in the compressor gave way and is flopping around inside. Got quoted $6200 to R&R my 24k btu 230V unit using my three knob controls. Hey said to replace just the defective unit would be close to half of the new. This unit is -3 yrs old and the other 3 are from 1983 and running perfect, go figure. When I first looked at the boat I was glad to see that the biggest of the 4 was new cause the others didn't look good. It's a split sys and thought about doing away with it for 2, single 12k units, one for the helm and other for rear of salon. Then as the others fail doing the same. So I'm looking for some suggestions. I know there are similar threads but wanted to start my own.
