Air Conditioner

We have a 2010 Greyhawk 31FK... About 2 years ago, we had the air conditioner replaced under warranty. Since then, we haven't done any summer camping, so we haven't needed it. Well, this weekend, in preparing to go out in a couple weeks, I learned that the unit that was replaced 2 years ago is now not blowing cold. Compressor comes on.. all that stuff... So, up on the roof I go, pull the cover and I see that the dealer replaced the original unit with a Coleman. Was the original unit a Coleman? I also see that the "new" unit lines were leaking, thus the reason I have no cold air.

So, here are my questions...

What was the original unit?

Do you think I have a claim with the dealer? I literally have not run the air once since they replaced it.

If I have to replace the unit, should I go back with an OEM? Coleman? Another brand?

Or, can I replace it with a larger unit? If so, which one would you recommend?

When thinking about going with a potentially larger unit, my generator is the Onan 4000.

Any and all help is very much appreciated.

What new unit lines are you referring to and how did you determine "they" were leaking? Photos would help. The entire refrigerant circuit is a sealed system.

Not to make you feel worse but I can't understand how you could go this long w/o checking it for operation.

I would start start with a call with the dealer who installed it.

Not sure about MH's but my Jayco 5er uses Coleman ac's.

JAYCO has always used Coleman/Air-excel units. Starcraft use to use Dometic and now they also use Coleman/Air-excel.

I think the warranties than run on the units are 1 year unless extended. I don't know how long that dealer guarantees their repairs, it's worth asking.

I've replaced units before - at least the dometic kind. The hardest part is getting the unit up on top of the RV, everything else (assuming you're getting the same unit) is bolt-on. In the case of dometic, 3 parts need to line up:
1) The AC unit itself - ducted or unducted
2) The control box (under the AC unit)
3) The thermostat, which much work with the control box

I haven't dealt with the Coleman unit that's in our Jayco yet.
