I realize that the penguin is what they call a high capacity AC. With this going on the third Brisk Air installed. I am willing to chance it on their dime.

My original was a '13 model. Lasted a week. The replacement, also a '13 lasted till this summer. So problems have been around awhile. With other people also waiting at your dealership and mine, I am going to say that they still have problems.

Lowest bidder, usually doesn't bode well for quality.

Got my camper back today. Ran new A/C at home. At start up 91 degrees in camper. 96 outside. Ran for 30 mins, cooled camper down 5 degrees.

Happy. Happy. Happy

Had to shut down, storms coming with 60 to 70 mph wind gusts.

Will check out more tomorrow.

I'm having an issue with my 2016 Sierra. The Dometic 15K unit. The service rep I'm dealing with has been great and he told me something that may be everyones problem. He said that Dometic added a certain additive to their coolant on these models and a few others that would evaporate the coolant should their ever be an escape(leak). He believes this additive is causing the coolant to evaporate in the unit itself and has caused many, many problems. FWIW. He's saying mine will be replaced without issue.

My experience with A/C units is mostly with industrial units. Some auto and home central air experience. I will NOT say that your service rep is telling a tall tale but- -I've never heard of this one. I've known the service tech who replaced the two (2) units on my 2015 TT and I trust his word. He showed me that TSB that Dometic had sent out to service techs explaining that there was a "problem in the manufacturing process" and that Dometic was working with their supplier (in China) to correct this problem. Steve stated that he had called Dometic and talked to some type of tech guy there and that tech had stated that the problem was when the Chinese company built the evaporator they had "forgotten" to dip the evaporator in some type of solution that would clean off the residual soldering flux from the connections on the evaporator. I do know that by NOT cleaning off a newly soldered joint there is a risk that the leftover flux can/may turn into an acidic solution and can/may eat through the copper tubing causing a tiny pinhole leak. I agree with that scenario as to why these fairly new units have the refrigerant leak out to the point that they no longer will cool.

From the perspective of Physics 101, this is not possible. These systems are closed and sealed systems, and the material used in the cooling processes changes from a liquid to a gas as the transfer of heat is achieved. Many folks think that an "air conditioner" cools. It does not. What it does is absorb heat (inside), and move it to a different place.(outside).

I also understand that the sealed units are aluminum, which has always been difficult to "solder" like copper which is very easy to solder. I've been told that there was a failure in the process of connecting the component parts which resulted in a leak and resulting loss of freon.

When my unit failed to work, it was initially difficult to troubleshoot because the blower system ran fine. The compressor easily kicked on, and sounded perfectly normal. But the temperature never changed. When I climbed up top with my IR thermometer, I could tell there was no heat being moved anywhere because the temp on both sides of the condensor coil was unchanged. There was also no change in temp on both sides of the evaporator coil. Total loss of freon. Even if the compressor had a leaking check valve, there would be a small movement of freon, and the resulting movement of heat.

Dometic definitely sustained a failure in the manufacturing process. I sure hope its resolved.

We havent camped since the AC was replaced, because of a new grandbaby....but we have a trip planned in Sept. I probably should go turn it on and let it run some now, while its so stinkin HOT!

Update on Dometic A/C

Got the dealer to install the replacement A/C I bought while waiting on the warranty replacement. Went to Disney for a week and the new unit stopped cooling. Got home Sunday and called dealer to see if the warranty replacement was in and he said no and he did not know when it would be. So now I have 2 15K Dometic units that are bad and no replacements. Not a happy camper

I just had a second unit replaced under warranty, and it only took them about a week to get one from Dometic. I don't know what the holdup is on some or your units.

Well I guess I have a dealer that is dishonest. I called Dometic and they said my replace unit for warranty on the 1st unit was delivered on the 2nd of Aug. On the 2nd unit they said I HAVE to take it to a Dometic dealer. I offered to sent it back to them on my dime for them to ck verfi that it was bad and they said no. Dealer has not called me back or answered my emails today.

Bummer about that.
I'd see if I could find an RV service place (even mobile service) that would handle the newest one for you.
