Air conditioner advice

I am purchasing a 1970's Airstream from my daughter this spring. When she bought it, the owner told her the ac was working. However, the "repair guy" in our area said it was not working and offered to replace it for $1200. I would like to try to do the replacement myself (with help of a couple of knowledgeable friends). Any advice? Is there any testing of the unit we should do first before just believing the "repair guy"?

Not sure on how you test AC to see if it's no longer any good. But I have installed 2 AC units in SOB's and if you can change a flat tire you will have no problem. You will need a extra set of hands.

Hi NevaH. Welcome to the forum.

The Duo-Therm Penguin 15,000 BTU air conditioner would be the standard replacement unit to use. A web search will give you prices. There are cheaper units that will work but they are higher profile and lack drain connections so condensate will drip down the skin of the trailer causing staining.

It should not be necessary to replace the air conditioner unless there is a refrigerant leak or the compressor has failed. Such failures though not unheard of are fairly rare. More commonly, the potential relay, start capacitor, and fan motor will fail. These can be replaced easily and parts are inexpensive.

Another thought; if it's the original Armstrong unit, those are quite repairable. Starter caps are often all that's keeping one from getting going.

There is even a member here that, when he repaired his Armstrong, added a Heat Pump function to it!

Here's a link to that thread:

I would at least get another repair guy to look at it. Bill Thomas camper sales enjoys a good reputation among the people I know.
