I posted this on a thread titled "Dometic Brick Air II'. You might find it of interest. Plus, this unit has been out for over 6 months.
Just a few observations that I have recently become aware of.
I had a client with a 2006 Country Coach diesel pusher that had 2 older model Penguins on the roof....both 13.5K heat pumps. One went out (lost refrigerant) and the new Penguin II was not compatible with his existing Comfort Control I thermostat system. He opted to buy 2 new heat pumps (15K) and upgrade to the new Comfort Control II system for better service and parts availability in the future.
After about a month, he was on the road to a summer vacation in Maine and called me from a large RC service center. He said that his new Penguin II units were extremely loud and were vibrating excessively. He called Dometic tech support and was told that they are having problems with the new compressors needed to properly handle and compress the new R-410A refrigerant that is required now for air conditioners.
Part of the problem is that R-410A is harder to compress than R-22 and requires a more robust compressor spinning at faster RPMs. This makes them prone to excessive vibration and noise.
The Dometic folks offered to replace the both Penguin II units with the Brisk Air II and pay for the change-out labor. The client accepted. When he called me, the tech was having problems getting his new units mated to his CCC-II thermostat, so I talked him thru the process of dip switches and thermostat re-sets.
The client called me the next day and stated that he was very happy with the new unit's cooling capacity (both 15K units) and especially the much lower interior noise level of the Brisk Air II units. He also said that while he was NOT happy with the elevated look of the new units, it was a trade-off that he was willing to make for the reduced interior noise levels.
I have to say that I install about an even amount of both types of units and I have heard complaints about both. I especially took note of this client's reactions as he is in the analytical field and has excellent observation skills.
Something to consider.............
