Our 1981 Excella II has its original unit. It is noisy but still cooling OK.
Just keeping our fingers crossed.

What if the air conditioners in Airstreams really are not that awfully loud, but the interiors of Airstreams, (new and old alike), absorb very little sound, and reflect a lot of sound?

What if what we like most about our Airstreams make them very difficult to cool?

The conduction of the aluminum skin, trusses, and inner skin is often cited as a cooling issue, but the coveted shiny skin itself is not often cited.

The aluminum skin gets VERY hot in direct sun, and not just very hot, but very, very hot. Like to the point where a person can see a trace of steam rise from the surface when sprayed with water on a hot sunshiny day.

A person would think that a very reflective surface would reflect most of the heat away, but that aint so.

Our air conditioners would have a much easier time if our trailers were painted a lighterish color.

I have to think that our friends with Argosy trailers fare better in the summer....

We have a 10 year old Dometic Penguin on our trailer. When I changed out the original plastic pan to the cup drains last year the sound level in the trailer was much less obnoxious. I think the foam gaskets helped to "decouple" the AC from the trailer so less sound is transmitted to the trailer.

The original Coleman died while I was having my AS serviced at JC 4 years ago. Was replaced with a Dometic.

The Armstrong unit on my '73 is still working well but I had to fiberglass over the shroud and paint it because the sun was dissolving it. The condenser airflow exhausts straight up out of my year and that allows leaves and other debris fall into the grill, a slight design defect that was corrected a year or two later. The unit will probably run for a long time to come as I don't use it much. There is really no set lifespan for an AC unit, it sort of involves a bit of luck as far as I can tell. Just keep the airflow free, the voltage up and don't short cycle the compressor and they can last a long time.

Our A/C unit is an Emerson, and it appears to be the original from 1988. (We have an 88 front kitchen, single door "squarestream" Argosy.) It does a fairly decent job except when the outside heat is over 100 degrees. It's not super noisy, but the thermostat has failed, so now we have to turn it on and off with the wall switch that turns the A/C off when the circuit for the Microwave is on.

We've been wondering if replacing it would be our best bet, but before we do that we hope to add one for the bedroom - there's a ceiling vent that we think we can use to install a second one.

Newer A/Ss have some sort of white coating on the roof which apparently does a better job reflecting heat than the shiny aluminum. There is a thread on this Forum regarding this subject that discusses the use by some posters of white roof coatings they claim substantially reduces the heat load inside their A/Ss. One I recall was called "Buskote" if I've spelled it right. My off season project will be to try that on my '67 which still has the original operating Armstrong on the roof which needs a little help though it runs well..
