We have a 2000 Beaver Marqis with AC problems. We were told that one compressor was working and one was not. Apparently SCS (AC manufacture) is no longer in business and no one sells the replacement compressors. Ours is a 2702 Model. Was told that a 2702 has a drop in replacement (ductwork has to be reworked) - Coleman Unit Series 6536. Unit is a 2 ton heat pump and doesn't cool as well as the 2702 and is pricy (around $3,000). Does anyone know of any other options to get the air conditioner up and cooling again?
