Congratulations on purchasing An Airstream. We love our 2018 25 foot FBT .
We live in Southern California haven’t traveled anywhere we have needed more than just the one air conditioning unit. Depends on your use . Airstream community has many folks who have debated this issue. I’m sure you will get good advice and recommendations. Think about the trip you will take now and the ones in the next five years. I’m sure you will make a good choice. Happy trails hope to meet you down the road.

We are often in places without electric hookups so our criteria was if we can’t run it on a small Honda generator plus our 500w of solar it doesn’t help us much. In the Pacific Northwest and equivalent latitudes in the west our single AC unit was been more than fine.

Not that it should influence your decision but I found it easier to upgrade the trailer’s 30Amp service to the 3000w hybrid inverter (where every outlet is live) than it would have been with 50 amp service.

Seems like it should do fine with one.

Our single air conditioner keeps our trailer very comfortable in + 90 ° F temperatures, although it probably takes longer to cool down after a day of travelling.

The biggest disadvantage of the second air conditioner is loosing the Fan-tastic fan in the bedroom. This fan when open (even if not running) is great for circulating air when an air conditioner isn't needed and for letting in light on a gloomy day.

You'll get both sides on this. We ran into a fellow Texan a couple of weeks ago with a new 25' International, 2 A/C units. Said he wished he'd gone with one because 2 require a 50 amp connection. We have a 23' and can get frozen with one unit. Just sayin'.........

One or Dual AC

We live in Florida have have no problems

I suppose it’s worth thinking do you want 50 amp service or 30 amp.

Do you want to loose a fantastic fan for a AC unit?

There are pluses and minuses to both. We did not want the dual AC

However, never having owned an Airstream, I wanted to ask.

Thanks in advance for your thoughts.

So we try not to camp in those conditions. If you will be regularly camping in those conditions you should get two ACs.

It wasn't cycling, if I remember correctly, but we were never uncomfortable. It had the mouse fur walls and vinyl ceiling overhead so no exposed aluminum.

Our 2002 Classic 30 is another story. I will probably end up putting a rear unit in it.

Hi, our 2005 Safari has one 11,000 BTU air conditioner and cools our trailer just fine. Like above, our Safari has small windows, mouse fur walls and a padded headliner. Not all camp grounds have 50 amp service and I wouldn't want to fight that huge power cord. Going on 14 years and no air conditioner problems. [must be a new problem]

We have 2015 25'FC with single AC. It has been fine but I agree with other comments on its how and where you plan on using the AS. If I bought anything bigger than a 25' I would definitely go with 2 AC's but using our 25' has been fine and we have traveled to GA, FL, TX, NM, Oregon, Washington state, and all states going and coming from our home in North GA over the last 4 years.
If I was full timing and lived in FL, deep south, or out west, dual AC's it would be. Good luck with your purchase.

How about some objective evidence?

In our experience with our FC 27 FB, our one AC will cool the trailer about 15 degrees under outside ambient temperature. If you want more cooling, you'll need two ACs.

In our case, we're in the NW and are heatophobes, so we don't spend time in southern CA, AZ, or Mexico in the summer, so one AC (and the 30 amp cable) works for us. If southern latitudes in the summer work for you, I'd suggest twin ACs.

Atwood 15K heatpump more than adequate for our 34'

Just got back from the beach at Topsail Hill Preserve in our 1994 34' Classic to test out our new Atwood 15K heatpump. Did just fine with the outside temp at 88. Ran it on low and my wife asked me to make it warmer. She was cold.
I've had all the other a/c's except Coleman and this is a wonderful quiet unit that does not use a lot of amps. Highly recommended by a real user with experience.

If you are going to get a single AC see if you can upgrade to a 16000 btu vice the factory installed 13,500 btu. I’m hearing people with that AC don’t have a problem. I have a single 13,500 and on hot days it’s warm in the trailer. But the trailer cools quickly at night. One more thing and please remember this. Make positively sure your shore power connection is firmly connected to the male connector at the trailer, then tighten up the ring on the female end of the shore power cord. This will keep from having those connectors from heating up and possibly melt the female end. And never drop the female connector because that ring will break. Like mine. I dropped it on concrete while winding it up to put away.
