Carrier Air5 LP -13.5K or 15K BTU

All--

I've got a '75 Safari 23' with a big old Armstrong on it. It looks like a Igloo Cooler that's seen better days strappet to the top of my AS.

I like the look of the new Carrier Air5 Low-profile (only 7.5" tall) but was wondering if I needed the larger 15K model? The price diff is about $80 but I'm not sure it's overkill or not.

Any difference in reliability between 13.5 and 15K modles?

I plan to get the heatstrip as well.

If your Airstream will "EVER" be in a hot area, you will appreciate the 15,000 btu unit.

The reliabilty is the same, for all the Carrier units.

Overkill, is not even a question.

on the dometic/duotherm side the differences between 13.5 and 15 are small.

they have the same energy needs at start up and under load.

the differences are related to fins/coils and fan (i think) which provide the 10% greater btus.

the bigger questions are...

WHERE DO YOU PLAN TO CAMP?
WHAT SEASON?
HOW MUCH TIME SPENT INSIDE A 23 ON HOT SUMMER DAYS?

living in the pnw, my house didn't have a/c and neither did my cars and i never needed either.

so i rarely used the ac IN the a/s, except in other locations, like east of the cascades or inland south eastern oregon.

with an older 23 a smaller (10 or 11k) could provide PLENTY of cooling most of the time, in your locale.

AND with the potential to be powered by a smaller genset....

IF the 13.5/15k unit is selected, you are committing to shore power OR 3500+ watts on the genset side.

cheers

In my 29' I believe I have a 13.5 BTU unit and it froze us out inside the Airstream while it was 90 degrees outside.

It really does depend on where and when you intend to camp. Here in Central Texas, I can't imagine using anything less than 15K BTU for camping between the months of March and October.

My 15K BTU iced me out at 90-95 degrees. But at 105 degrees, with no shade, it took everything it had to keep my 26' vintage unit cool.

13.5 carrier unit

I'm new to the A/S worldand I'm looking at M C Surplus Plus for a Carrier V 13.5 for $399.00 and $49.00 for heat strip. This is the best buy I've found. I have camped for one week and ran the no name 8000 BTU window unit in my driveway while working on her (out of the kit window) it has kept my 60' AS plenty cool. I feel that a 13.5 unit centrally mounted in the ceiling would have to due a better job.Carrier is certainly a name I trust,besides I'm excited about this shower of cold air it boast in advertisement. Im going to use my Ebay 10% off coupon to lower the cost to 491.40 inc shipping. As im on a budget and AC is a absolute must in the hot Ms. sun I think this is best avenue to proceed dwn. I let you know how it comes out.

When the sun is shining on a hot day, I could use a 2nd AC on my 34’ Airstream, even with the 15K AC. If you’re ever going to be in the south, (perhaps NatchezBear…) you won’t regret the 15K AC.

As you know, it gets hot in MS.

Darn hot.

I'd keep looking to see if you can find a deal on the 15K BTU unit. Seriously, I don't think you'll regret it.

I’ll admit, that looks like a good price.

I went with the 15K heat pump model, see http://www.airforums.com/forums/f427...ead-40795.html. I have the center dinette in my 34’ Excella, and the “Air Shower” vent drops cool air right there in an area, including the stove and sink, that is otherwise missed by ceiling units.

I'd go with the 15k. The 13.5 is OK in my 20', but I think anything bigger than a 20' would need a bigger unit.

You're right about that, Marcus. I installed the Carrier Low Profile 15K with the heatstrip, but it did cost a lot more than than what NatchezBear found. I purchased it locally. It cools our 26' very fast on hot days. I don't think the heat strips do much to heat the camper. I later installed a new furnace because we do like to camp in the mountains.

We have a 13.5 (w/heatstrip) in our 30'. Even on the hottest days, we've been OK, albeit with the help of an oscillating fan at the warmest part of the day. We've been to the third coast & Big Bend during the summer, so we've some experience with it...

That being said, the sucker was on all the time ... at some point, when we're lighting cigars with hundred dollar bills and run out of other Airstream remodeling things to do , we'll replace it with a 15K (with heat strip).

The biggest thing is that on a summer night in the bedroom, in central Texas & coast (warm + humidity), the oscillating fan helps out alot. We're thinking the extra from the 15K will make a difference.

All--

I plan to do some camping out in the Steanes Mountain Area in South East Oregon where it get a bit on the hot side. Yes, I'll be looking for shore power and probably invest in a generator, ideally LP powered.

The main reason for the heat strip is to help keep the trailer warm during the winter when I'm not using it. I'll probably have to rig up something to get the right duty cycle... but that's not too difficult, just takes times.

Based on the freeback... I'll be looking for the 15K version. It's just not that much more.

I have a Carrier AirV 13.5 on my 1965 22' safari and it will freeze you out. I also have the heat strip and it does a nice job of warming the trailer in December here in Va. The reason I went with the 13.5 was I can run it with my EF2800i Yamaha generator with no problem. We do mostly boondocking.
