Atwood Air Command AC/HP

Dometic penguin, which is what was oriiginaly in the coach.. I let my favorite RVt tech ttalk me into the Atwood. The Atwood reportedly classed as 15,000 btu per him is actually closer to18,000. Think he was correct. Had great cooling, more air flow, much quieter all great. The heat pump just would not provide enough heat to raise the temp in the coach .like the domestics.

It was never designed to heat like heat pumps in the rest of the world heat. After one year I took it out and got rid of the piece of junk

What did you replace it with ?

Sounds pretty much like mine worked. 2 units ducted together. . Mine would put out heat until the sensor in the duct would register about 70 degrees then shut off. No where did it ever sense room temperature, consquently the room temp would never raise regardless of TStat setting. Inside the duct would stay at tabout 70 degrees, but never the coach. I talked to Dometic as did my RV tech many times about it. I talked to factory reps about . All said it was working exactly the way ir was designed by Atwood and since acquired by Dometic they had done no design changes especially to work with ducted systems. My Dometic units put out 100 to 110 temperature air until the room reaches thermostat setting. Atwood, unless Dometic has changed it in the last year or so, will never work that way.

Too bad the rv association does not assure that all products installed on rv's work and not just an inferior product with no recourse for the end user....

Were these two the DUCTED units? or were they the NON ducted models?

Both ducted on a single rig. Operation is kind of odd- the indoor blower only comes on when the coil is hot, so it cycles a bit, but never blows only warm air.
