Mini Split Air conditioner installed in a Class A RV.
Hi all, I have successfully installed a mini split air conditioner on my 30 foot class A rv. It's a 9000 btu unit, and it is working very well. As you'll see in the pictures I have a few minor things left to finish but it has been working for several days in the hot southwest.
Once I removed the original TV and small cabinets, I bolted 1.5" aluminum angle stock to the frame on the sides. The bottom piece of angle stock is 8' long and slipped perfectly into place on the remaining shelf frame without cutting. I did have to hammer it down on one side to get it in there, it was very snug. To that I bolted a single piece of 3/4" plywood. To that I used more angle stock to make a plumb mount for the head unit's mounting plate. It's all very strong, and I can hang from it with no flexing. I weigh around 170 lbs.
Before mounting the plywood I put a sheet of insulation on the shelf. You'll see my comical attempt at adding some extra insulation with expanding foam.
Luckily the condensor fit with a couple inches to spare, so no modification to the compartment was neccesary, other than making openings for the intake and exhuast air.
To the compartment door I used gorilla tape to seal the opening and a couple pieces of 1" aluminum angle stock to provide a solid backing for the nuts and bolts.
It's very quiet and runs cold enough that I have to keep it set to 80.
