Air conditioning performed admirably.

These unheard of high temps presented me with an opportunity to test out the A/C in my old trailer. The ducted Coleman Mach III is 17 years old, as is the 24' stick and tin trailer it's installed in.

With temps hovering around 108 inside and out, I was hopeful but not very optimistic. The trailer was about 3/4 shaded. After one hour, interior temps had already dropped almost 15 degrees. After two, the interior temp was 80 - 82 depending on where measured. At that point I was feeling a little guilty about hogging power and shut down my little experiment.

I'm very happy with the results and am no longer nervous about adventures to the south in the summer.

Based on some of the stuff I've read here, I thought it was worth sharing.

They built Air Conditioners better back then. I don't know how or why but the old ones work better then the newer ones. The new ones are probably more electric efficient though.

Older refrigerants were more effective at cooling but were phased out for atmosphere damage reasons.

He says it's 17 years old. That makes it a 2004. The older refrigerants were phased out long before 2004.

Actually 2004 is when R22 started getting phased out and it wasn’t until 2010 that new equipment couldn’t use it. Plus RV’s can be built with older inventory so it’s totally possible it was using older refrigerant.

based on what I remember 2009 was the last year that new equipment could be shipped with R-22, starting in 2010 you could still purchase new split central air A/C units for R-22 but they had to be shipped with nitrogen...This is as I remember when I installed Central air in my last house in 2010, I just went with 410A. I going to guess the rest of the industry probably followed similar timelines.
