A little different but related subject to installing my two Penguins in my truck conversion.  I stupidly did not test the units right out of the box to make sure they worked-I just assumed that since they are new they will.  So I went through all the modification of the units to the point that now I cannot return them.  One worked perfectly, and the other didn't cool-although the compressor was running.  I had an A/C guy come out to look at the unit.  He poked a hole in the low side return to the compressor-and no freon!  That either meant a hole in the unit or just no freon was installed from the factory.  The A/C guy istalled a service port. He pulled a vacuum on the system and we could see there wasn't a hole in it (thankfully).  He installed the 23oz of R410A freon and the unit worked perfectly.  Now with the service port installed, if it does have any kind of leak, we'll be able to tell right away.  Moral of the story-check to make sure that piece of new equipment works before installing.  Good Luck, TomC

I don't doubt that I installed a Penguin they left out the capacitor their quality has gone to the dogs since moving to Mexico and the 20 dollar a day labor trouble around here with the Penguins last year they used solder on the lines on the 410 system instead of brazing they all broke.

The Cruise/Air systems made by Dometic in Mexico are junk now with the China made motors and compressors and that is a real shame it was the best unit on the market for a split unit in a RV but that is what we get with a foreign owned co like Dometic

Wow, makes me want to climb up on my roof and kiss my 1979 Dometics. They look horrible, wiring faded, aluminum fins corroded with some just gone. I should find and squirrel away some old units off of an old Winnie or something vintage. I am shocked every year I turn them on and they still work.

Any manufacturer is exposed to quality control issues.

Especially when the segment costing is driven by re-sellers.

Even if yours was better, which will cost you something more than the other guy to do, you will have an uphill battle selling them to vendors and manufacturers for the higher price.

There is effectively no price spread on roof top air conditioners, they all retail for the same price.

The question might be:

Which manufacturer or re-seller is the most responsive to making things right in a timely manner?

happy coaching!

Me too. I don't think they have much quality control in china. I assume that's where a lot of the parts are made.
And tools as well..

I don't find many parts made in China, mostly Mexico but the parts made in the US are no better.

However, many tools are made in China. They are cheap and you get what you pay for. Chinese tools only used once in a while are OK but not for everyday professional use. Unfortunately many US made tools are no better!

I think the whole mess is caused by us buyers looking for the lowest price so we are as much to blame as anyone. You can always buy Snap-On but the price is high. Craftsman tools are the best compromise for me as a shade-tree mechanic!!

The Penguins are "assembled" in the US.  But open it up and you'll see the compressor from Indonesia and the fan motor made in China.  Do figure on that one.  Good Luck, TomC
