Replaced 13500 A/C's w/ 15500 A/C's

[Snomas]

We are replacing our 2002 A/C units w/ new 15500 units after having them damaged in a Hail storm several months ago. The 13500's did not do a very good job of cooling the MH in over 100 degree temps. I will be picking up the MH this week after 6 weeks of hail damage repairs. Those who have 15500 units, do they cool your MH reasonably well in high temps?

1. Newmar Diesel pushers, when you have them spec'd out with 2- 15k AC units, they will freeze you out.
2. Hopefully, they add the gasket between the Intake and Exhaust which is REQUIRED on Newmar top mount AC units. In-experianced Service Techs not familiar with Newmar will forget that gasket separator and then the units will NOT put out much air volume inside.
3. 2002 model. Count your TOTAL intake and exhaust round vents in the ceiling. Should be about 18 total. 2002 was when Newmar realized that they did not install an adequate number of intake and exhaust round ceiling vents. But, around this time, Newmar started using a slightly larger diameter vent which did not require the total of 18. To tell the difference between the old and new round ducts is simple
The OLD style, the round louver that turns sticks down about 1/4 inch
The NEW style the round turning louver is flush with the mount flange. Doug

13500/15000= 0.9 so expect about a 10% improvement. Outside awning shading the windows would be much more of an improvement.

I replaced ONE of my 13.5's with a 15 a couple years ago, Yes it does a better job, Bit more noise, same power draw (more efficient). Blew up on my a couple weeks ago (Condenser fan flew apart, cost me 15 bucks to fix.. As repairs go, that was a cheap one).

For us, with temps over 100°, the cooling is not that great without our Prompt Sunscreen windshield cover, window awnings deployed and roll-shade 90% "screens" down. Hope you aren't disappointed with the results for the added expense.

we have the 15K in our 31' TT and it will still be a struggle with temps in the 100 degree range, but the 15K doesn't work as hard as the 13K and it cools down and shuts down faster.
