I was in a friend's SOB a couple of weeks ago, and it had a Penguin low profile air conditioner in it. Just my impression, but the control switches/knobs and bright-white, injection-molded plastic cabinet felt cheaply made. Also, it seemed significantly louder than the AC unit on our 2005, 19-foot Bambi; so much so that it was difficult to carry on a conversation when standing or sitting directly underneath. However, it did get really cold, fast; and it moved a lot of air.

If you don't install the condensate pump, the condensation accumulates and drains to the outside of the unit down the side of the trailer, not inside. The weeks I have run mine, constantly might I add on low fan always, we have dogs inside, it has never even hinted at freezing up, and at 3/4 on the cool button. It cycles as it should. Judge for yourself on the air handler box. I like it.

The inside AC cover on my Penguin developed a small crack after a couple of years. The Penguin may be a little louder, perhaps because all the guts are sqooshed down cloer to the roof opening. It did freeze up on me once when it was very humid outside. Overall though I am satisfied.

If I had it do over I would prefer an AC in which the fan as well as the condenser are thermostat controlled. On the Penguin after the temperature setting is reached the fan will continue to run until you shut the unit off. Which conversely means you have to turn it on again for the next cycle. Anyone know of an AC which turns off the fan as well as the condenser thermostatically?

I think the latest ComfortControlCenter thermostats for new Dometic ACs let you turn off the fan when the compressor cycles off. I'm not sure if I'd like that... if I fall asleep with the AC running I'd probably wake up when it cycles off and think we'd had a power outage. When I'm awake I can hear when the Armstrong cycles the compressor on and off, but with the white noise from the fan I never notice that while I'm sleeping.

I thought both the Penguin II Duo Therm and the Mach 8 control the fan and compressor by the thermostat "IF" it is set to "Auto". If it set to Hi or Low, then the fan will run in either setting, while the compressor kicks in and out as needed to maintain temp.

Can anyone confirm?

Nice install Jimbcole- Man that thing is SHINY inside- very cool!

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?

Atwood A/C

Installed an Atwood 15,000 this summer---it has a heat pump --- talk about quiet---you don't have to raise the volumn of the TV when it comes on ---outside you cannot hear it running---can't believe how great
It cool the trailer. Did not know Atwood made an AC ---check it out it will make a believer out of you.

That's the way mine works.

First I've heard of that... Is it the Command like this one HERE?

I didn't really search, just used the first one I found, but $689 complete with Air box, roof top and remote is not bad. I know nothing about them though.... Does it not use a wall mount thermostat? Looks like its built into the ceiling unit?

Wonder what db level the noise is- wish they included that in specs. I saw one post where a member recorded 58 db on his Mach 8 from the outside, which he said was loud....

I few months ago I was in the process of replacing the two 8 year old Penguin AC's on my Airstream 396 XL motor home. My 1st choice was the new model Dometic Penguin II 15,000 BTU units. I had heard of some issues on another forum that had come up with the new Penguin II units and was looking in to the Dometic Brisk II Air units as an alternative. Lewster posted in post # 2 http://www.airforums.com/forums/f427...er-106384.html with more detailed information on the Penguin II issues that related to the a problem with the R-410A refrigerant that is required now for air conditioners. Maybe he will see this thread and provide an update. I ended up installing the Brisk II Air units and could not be happier with the cooling and sound level. These are not low profile but on the motor home I wanted the best cooling and noise level that I could get. I have talked with my local RV service shop and they say the Penguin II issues still comes up on some installs that they made. In any case you may want to check this out for yourself it may now be resolved.

Good luck

I installed the 15k Penguin II this Spring. It is much louder than the Penguin I 13.5 unit it replaced. My old pan was cracked, so I went with the cups. I like them much better. You place a single 1" gasket on the roof, then place a second 1" gasket on top of that one which you make cutouts for the hoses from the cups. The hoses run to a "T" fitting which connects to the original internal drain line.

With the upgrade of the Penguin II it was cheaper to get a new Comfort Control Center II than add the components to make it work with the original Comfort Control Center. There are fan settings of Auto, Low, High. When on Low and High, the fan runs continuously and in the compressor cycles. In Auto, they cycle together.

Note: My unit has the heat pump also. Some friends installed the PenguinII A/C only 15K unit and it is much quieter than mine and blows colder air. Bad expensive decision on my part.

Well one thing I can clarify for myself and anyone else who caught my first post....

Part of this thread was/is to determine if the Mach 8 is worth the $1000 price point VS the Penguin $750 price point....

However, I am seeing now that the Penguin I was looking at was the "cool only" model 641916, where the proper comparison is the Penguin "Heat Pump" Model 651916 is also right at the $1000 price point.

So with price being relatively equal, this comes down to reliability and performance.

Is there a concern with the Mach 8 being relatively new product? Which company & product has been around longer? Which has best warranty, customer service, parts availability, etc?

A post earlier suggest the Armstrong is an oldie but a goodie. That says alot about a product. However, mine is filthy, and looks terrible on top of my shell off restored Airstream...

More food for thought...

Aviator- how does the CCC2 work? Is that only for multiple ac units, so you can control them from one master panel? Or does it give you more options???

When I first saw it, I was thinking it was so I could locate separate temp sensors in the bunk area, vs the front gaucho/ dining area, etc. but that doesn't make much sense...
