Question AC Can You Get An Efficient System?

The AC I have makes a lot of noise and little cold and sucks the power. Is there modern more efficient units out there? Bet there are no DC units for boondoggling...

Wife like's AC, I hate it

What exact brand AC do you now have.

Forget the 12 volt DC issue. No such animal.

Most new AC units are efficient.

Andy,

It's a Duo-Therm by Domestic. Figured there would not be a 12V version but thought I'd ask.

The original AC for a 1964 was mad by Armstrong and it was model # TAC-110.

Obviously it's been replaced with a Duotherm, but you also say Domestic, which is really Dometic.

The question becomes which model so that you could know how old it is.

Please post the model number and I will try to help you determine it's age.

I've always wondered if anyone made a 8K btu type unit as the 13.5 and 15K units are Way too big for the smaller trailers. Andy? Our 15 blows like a freezing hurricane!

I believe the Coleman "Polar Cub" is an 8000 BTU unit.

Rick.

There are 4 choices, for roof AC's.

7,100, 11,000, 13,500 and 15,000 BTU.

For your 23 footer, plus being in the southern US, I would feel that the 13,500 should do the trick for you.

But, when you get those nasty hot spells that sometimes last for weeks, a 15,000 does the trick.

Also, since you have a nice looking trailer, an Airstream, putting a 7,100 BTU AC on it's roof, will make it look horrible.

Keeping the thermostat up a little higher should help your issue with the AC.

When it comes to AC's, a little more cooling is always better that a little "not enough".

Andy

I installed a 8k btu window AC in my Safari. Craigslist=$50.00 came with remote control even. New in the box cost about $200 to $250 compared to $1200+ for that low-profile coleman roof-mount job. It gets my Safari down to 65degrees on a 90+ degree day. It can easily be run with a 2k Honda generator, along with a few other things. Mine is mounted in the former furnace location and slides out for use so it can drip right onto the ground. I have since installed the old furnace shroud to the sliding tray so you can't tell it's there.

Rich,
That's a pretty cool and economical idea. I may consider that. So, is there a tight seal around the air conditioner? If so, how is it sealed?

Thanks, Michael

Part of choosing an AC, for an Airstream, is does it have a drain pan available for it, so the water does not run down the side of the trailer.

The Carrier, is the only unit that did not require a drain pan.

The aluminum plate that the shroud mounts onto was riveted to the outer skin, so I drilled out the rivets and installed a gasket onto the back of the plate. I will eventually replace it with a riveted on gasket. When opened it has a foam gasket that will seal to the inside wall of the Safari. It's not as critical as the outer gasket, as it won't be used when it's raining anyway, Unless it's a really, really hot rain!

Have you detailed this installation in a thread?

Nice,

Hi Carol,
I have not done that yet, but I find myself answering a lot of questions about it so I better get to it, huh? The installation is not complete yet, but the issues of mounting it and sliding it out are done. I will start a thread on it, and I appreciate the comment.
Thanks,
Rich the Viking
