AC repair vs. replacement

I have a 71 Safari and the AC doesn't get cold. It blows plenty of air but never gets cold. Also, the "dog house" on the top is totally destroyed. Does anybody have suggestions about trying to fix it, or should I just replace it? If so, any suggestions to model and installation tips? Thanks

I'd contact a local RV repair place and get a quote on going either way, then make a decision. A/C is one of those areas I wouldn't touch except to put in a bottle of freon in the car.

First question is, does your trailer still have its original AC? One way to tell, is that the originals in that rough time frame, were typcially riveted or screwed to the roof with a million fasteners.

If it is original, then there is a running debate: there are those who maintain that "they just don't build them like they used to," and that the old AC is worth finding someone who will work on it, rebuilding/repairing whatever needs it, and then making the conversion to modern coolants. I still don't know how you would deal with not having a shroud. I'm really doubtful you could do anything but make a custom one from scratch.

I was of the opinion that my ancient AC on my '73 wasn't worth the trouble. Mine wouldn't even blow air, so it was easy to imagine all the things that could be wrong with it. Anyway, I removed mine and put a new, modern AC in its place. I chose a Dometic Penguin low profile. I think the smaller trailers look sleeker with a low profile unit. There are several threads that debate the merits of various brands. For me the Dometic has been fine in the year or two I have been using it.

Good luck!

Is the plastic shroud destroyed or the aluminum housing. If the housing is there, I'd find someone to rebuild the AC part. Or if you have some basic skills and tools, pull the parts that are no longer good and replace yourself, leaving the Freon part to the AC tech. If the compressor is still holding pressure, I'd leave that alone and just replace capacitors, transformer and fan motor as required. I just replaced the motor for fans, all capacitors and transformer on mine. The compressor was good, holding pressure good. The dryer/filter will need replacing due to rust eventually. But it will wait till it fails, hopefully at home. Good luck however you go. If you plan on rebuild, soak all bolts, nuts with penetrating oil now a couple of time, then clean all bolts with wire brush to keep from snapping or twisting them off. Jim

Shrouds are available for Armstrong A/Cs from Andy at Inland RV.

There are threads on here that detail rebuilding these units...

Think about it hard... My Armstrong is forty two years old and is doing a great job right now....

There is not a unit built today that will provide this kind of service.

If you take it off please don't trash it, but offer it for sale on this forum and/or Craigs List.
