Original house ac was pulled by the PO but those long drives in the fl sun are miserable. You literally have to put sun block on. And stay hydrated.

Sometime last year we pulled the radiator in the front (I think it's the evaporator) and scraped it. I would have kept it but you know... Blower and all that is still there

I'm thinking about pulling a complete system from a smaller vehicle and fitting it into the mc9. Anyone ever do anything like this? I'm sure it won't be too hard, all the original lines are still running down the middle

Jon -

Best would be to find somebody scrapping an MC8 or 9 and pull the entire HVAC defroster system out of the dash and re-install in your coach.  Call Luke in NJ to see if he might have one: 1-888-262-2434

MC-9s came from the factory with Driver's A/C, so no sense trying to re-invent the wheel for the dash components - especially since OEM is properly sized for the dash.

Figure out a way to drive an automotive compressor off the OEM compressor pulley on the 8V, and hang a condenser on the curbside transmission access door.

Welch Industries in Stockbridge, GA (outside Atlanta), has done a lot of custom bus A/C work, would also be a good source for help.

FWIW & HTH. . .

Most DIY folks use the Red Dot ,Pro Air or other manufactures evaporators sizing the compressor and getting the right amount of oil and freon can be a challenge to me you are wasting time and money to install a unit like you buy from the hot rod shops for a automobile

 If you lived in Az we have a place in Phoenix that is very helpful with helping and supplying the parts needed

good luck

I added a Welsh unit in my MC-8. I used all the org. things in the dash. the welsh compressor mounts in the blower compartment. the trick is running the lines. I also added a condenser mid ship for the kitchen area. Worked well.

Dunno fur sures.  He installed an A/C unit in the front dash of his older Crown Supercoach.  I think his installation story may be in the archives.  He still has the Crown...I think.  HB of CJ (old coot) Now Crown...less Sad
