The new a/c is a Coleman mach 15.
It is called a 15kbtu, but i think i saw on a lable it listed as a 14.5k.
The last a/c was a 13.5k mach 8 low profile.
I can report these observations.
Cooling: Not a dramatic difference although the mach 15 seems better. Mach 15 a simpler design. The Mach 8 literature says it is a more efficient design i think because they separatet air moving with 2 fans. Allows condenser fan to run full anytime its desired? So maybe at 13.5k and more efficient, it approaches a standard a/c at 14.5k? Idk.
Compressor quietness: When the two techs came inside to do the first turn-on, they thought the mach 15 wasn’t working. Thats how quiet the compressor is. I assume compressor vibration is low also. The mach 8 compessor was louder and wiggled alot. I think this caused/assisted the eventual copper tube rupture.
Note that the above may not hold for all purchases for all time as the mfr may use several different compressor brands on their factory line.
Your new model the Condenser fan runs ANYTIME the compressor runs. Yes, it is quiet. Funny thing is, the original 15, the Condenser fan system sounded like a jet engine. RVP redesigned the fan blade and Condenser motor system to be quiet like you have now. Doug
PS, you must have a OLD Airstream to have a factory installed RVP AC unit. A/S has used Dometic for almost 20 years now.
