Interesting! In hindsight you would rather have done the "cool only" model?

Thats good to know that if the pump fails, it just spills out onto the roof of the coach.... That's what I like to hear.

So there is no gravity drain out of the pan, huh? Everything is either pumped out clean, or spills outside? No way for a pan full of water to spill "into" the coach?
Correct! Spills to the outside! Thanks

Can anyone confirm?
If you have it set on low cool, with it at the coldest setting, and the interior reaches the desired temperature. (Which it does quickly) the condenser fan cuts off along with the compressor. The interior blower fan continues to run. When the temp rises on the inside, the compressor turns back on, along with the condenser fan, and condensate pump.

about the Atwood?

It cool the trailer. Did not know Atwood made an AC ---check it out it will make a believer out of you.
Thanks for the information! I've been wondering about the Atwood since I heard of it in the spring. Do you have a picture of it mounted?

Yes, I would have rather saved the dollars and noise and gone with the A/C only unit. When it is chilly outside, we use a couple of quartz heaters in the front and rear of the Airstream which gives us quiet even heat. The quartz heaters work down to and below temps where the heat pump no longer works and the furnace is needed. Thus the heat pump ends up not being used.

Cup drains. In the event your drain tube becomes plugged, there are overflow drains at the top edge which is located outside the gasket area and would allow water to flow onto the roof, then run off. The "pan" works much the same. The thing I like about the cups is that they are a smaller area, and I don't believe they will be as prone to cracking as the pans are. Most of the older pans I have seen had multiple caulk lines to cover leaks out onto the trailer roof. Each new caulk line interfered with the natural flow of the water by creating an uneven surface. From reading other threads on the subject, the consensus was that eventually all pans leak, and may leak in a spot which brings water into the coach. With the cups, they are always outside the sealed gasket area which prevents the possibility of leaks into the coach.

I'm going to bite the bullet and replace my AC while I've got everything torn apart. My original AC is working, but I figure its destined to go out at some point, so might as well do it now.

Plus, I'm assuming a new unit will be far more efficient- especially if I upgrade to 15k BTU.

In reading all the posts about these units, I'm still unclear on which is right for me.

The Penguin seems to have solid & consistent positive reviews. I'm not quite certain if there are any condensation drain pan issues, because I've read some posts that indicate they are using different pans, or possibly another design with "cups" or something.... Another member posted that the drain cups are visible from the ground and dont look good aesthetically. At the $750 price point for the 15k heat pump, this seems to be a great value.

Mach 8 looks to be too new to get a good feel for reliability. Posts I've read indicate a simple fiberglass drain pan, and simple 4 bolt installation. However, I'm reading mixed reviews as to whether the noise level is problematic. Not sure if a condensate pump is a potential point of failure, maybe its a non-issue. I know that in a home AC system, they are prone to failure and cause for water damage. The price point for the Mach 8 is right at $1000- quite a bit more than the Penguin.

In the end, I'm inclined to think that the cooling and heating performance between the two is comparable. However the Mach 8 is louder on the outside of the coach, and its $250 more expensive. Weight differential between the 2 is only 15 lbs. The Mach 8 is 1" lower profile.

Am I missing something that makes the Mach 8 more attractive? Ease of installation differences? Reliability? Service & Repair availability?

As always- love your input!
Thanks!

I think you'd be very disappointed comparing any new unit to a properly functioning Armstrong. Keep what you have and, if it breaks, get it fixed.
They were built to last, unlike new RV air-conditioners.

My impression is the coup de grace for Armstrongs is when they finally go parts are unavailable and they use the real stuff for coolant, Freon, which is a no no. Am I right?

I agree if your Armstrong is still working keep it!

Atwood A/C

I noticed that Camping World is now selling the Atwood-----in the details it says the 13,500 will work on a 2,000 watt generater ? I have the 15,000 and will put it up against any A/C out there, lowest db of any unit i have ever heard. Any it cools faster than any unit I have ever had. The remote control is standard and easy to use. Check it out and see what you think.

Just spent 4 days in 105 degree heat in Yuma, CO. Blistering sun and no shade. They parked us broadside to the hot afternoon sun.
The 40 year old Armstrong kept it bearable inside. Somewhere between 80-85f. It's pretty loud though.
I don't know if the unit could use a charge. The PO built an exterior shroud (not pretty) and riveted it to the roof. So access is not convenient.
Somewhere here there is a thread on upgrading the old units. Just can't find it right now.

Replacements for the compressor and fan motors are available and all the electrical parts like capacitors and such are generic, there's a parts list in a thread written by a guy who not only rebuilt his Armstrong, but made it a heat pump in the process!

Armstrong units don't use R-12 (the unobtainium formula that was used in old automotive AC units) they use R-22. This can still be manufactured, but newly-manufactured units aren't supposed to use it anymore. They can still make the refrigerant until 2020, and can continue to use recovered/recycled R-22 even after that.

On my dometic penguin unit, the fan runs a constant low or high speed with a variable cooling temp. I do not see how it could be any other way. If you consider the size of space we are cooling to the BTU calculation formula AND factor in the lowest insulation rating, a 25' Airstream requires only 6000 or so BTU to cool it. One thing that happens is that if AC units are too large the humidity (in a humid climate) is a dead give away to inefficiency. The unit cools the space before pulling the moisture down to a comfortable level. The space becomes cool and damp. The only solution is to increase air circulation to somewhat counter the effect or get a smaller unit. The formula accounts for heat radiation, volume, insulation, etc, etc. Nonetheless, RV owners want bigger units.

When I first got my AS I took it on a camping trip with a day ambient temp in the nineties with one of those almost ready to rain feeling weekends. I had a temp gauge and humidity gauge inside. On low fan max cool the unit cooled the camper down to about 68-69 but it was damp. About six hours later it froze up. I let it thaw and then set the fan to high and temp to mid point. The inside temp went to about 78 degrees F and humidity lowered to the low sixties (percent). Obviously the AC was working fantastically to get such a low temp in a hot environment (I thought 20 degree diff was a limit) and it did not freeze up the rest of the weekend - more circulation took care of that.

What about the type of cooling unit rather than brand? AC is great for humid climates but what about dry areas? I always thought they use swamp coolers or other devices- heat pumps, etc. Are there different devices for RVs? This may also be the reason that people talk about their cooling units barely working, etc. Just a thought.

I too am going through this thought process. I have an 89 Excella w a Coleman Super Mach. Fan only works on low. Compressor kicks on and off. I'm in New Orleans (very humid) so it frequently freezes up with only mild temps outside.
Any suggestions???

Makes me wonder if I need to re-think the 15k BTU size....
