Can’t find a new ac unit

[[email protected]]

My local dealer can’t get any rooftop units til October but I see some on EBay and wondered what size to buy? I have a 2009 2619 and it cycles quick( every 30 seconds) P.S. I can’t get anyone to work on it so it seems best to just replace
Ideas?? I am in the St. Louis area

They are few and far between. Manufacturers are having trouble getting A/C units as well. As for what size, the original one was 13,500btu. If that worked fine before you started having issues then stick with that. I bumped up to a 15,000btu unit for my 3326 and it made a world of difference.

Should I stay with Coleman to make sure it fits??

Define “fits”... They almost all use the same 14”x14” opening, so I would imagine any rooftop unit would work. And the interior ceiling unit on the old Coleman Mach III was pretty big so I would assume most ceiling units would fit in that recessed space. The big thing to watch is overall height of the roof unit. If you’re just barely squeezing Intro a garage now, a couple extra inches up top may cause problems.

Thanks now I’m not sure if I just need the top unit or entire assembly

I just bought one for my 07' 2720. It's a Advent ACCOL 150B unit with the wiring adapter for a Colemen ADB/controls.Took about 3 weeks to get delivered. Be careful if you want to keep the original trim ring on the older trailers, alot of the new ADB's are to big to keep the trim ring. Coleman's does fit(15021) non-ducted unit.
Atwood was my first choice, but you can't find one anymore for a non-ducted unit. I called them and talked to a guy named Phillip and was told they are no longer made, only the ducted units are made any more.
For me a few inches of height loss does not make any difference at all, my storage shop has plenty of door height. I can see where this can be a problem for some people who are tight on space. I should be putting this on in the next few weeks. My old hurricane(Coleman Polar Mach) unit was just to much for the wife, she said its gotta go-TO LOUD.

Interesting that the Coleman ceiling unit is 15021. That’s the same number for the Atwood ceiling unit.

Sorry, wrong ADB number. That is the one for the Atwood, and they still sell it. That was the one I was gonna use with the Atwood ac that you can't buy any more. I went back and looked at my invoice and here is the correct part number for the Coleman ADB, part number 9430D715. I forgot to say that I got my ac from Etrailer.com and my ADB from PPL motorhomes.

Update, I replaced the ac with a Coleman I got from a supplier in Kentucky
It was super easy and I saved quite a bit doing it myself
I reused my old inside cover/control panel
