That sounds like a plan to me. I am located on the South East Coast in Florida and would love to meet up with other skoolies to swap ideas and learn about converting. Even though I am not converting the bus into and RV, I know that taking it out on long trips will be a blast if we have that A/c going.

Hey Christopher,

That Climax unit looks like the bomb! I searched for portable or window a/c that use the inverter technology like the mini splits. I could not find anyone actually selling them.

I am hunting now for the Climax and cannot find it actually for sale. Lots of pics & info but no pricing & availability. Where did you find yours?

the good bad and ugly about the Climax unit..

they are sold by Hotspotenergy and are pricey at $899. and they cool only, no heat.

ive been up close and personal with it.. when I got it in early June I ran it Non stop day and night inside my Hot-box bus.. 90s outside with dewpoint 70.. I just left it on while I was doing work and then all night to sub-cool the bus. after about 3 weeks it quit working..

I called tech support and they were awesome and said they could send me a new unit.. I asked them if we could troubleshoot it since ive pretty much bult A/C from the ground up. we found a power supply board had a burn hole in it around a rectifier..

they said it was a known issue , sent me a new board and its been fine ever since..

it is a 2 Hose system meaning it wont suck the cool air from your space to use as the condenser air.

in humid climates it likely will not drain water or need to be emptied.. it has a slinger to take the condensate and use to help cool the condensor coils..

engineering issues.. - it uses a capillary tube instead of an expansion valve.. they vary compressor speed to handle capacity changes.. but in my opinion a fixed orifice isnt the best for this in terms of efficiency.. (its still more efficient than an on / off portable)..

in my opinion the condenser coil is too small for the compressor / evaporator size.. when it was 100+ in the bus and I would start the unit up.. the condenser temp went way up and then the unit slowed its compressor down.. the coil isnt very big.. thats not a bad thing in and of itself but the higher the head-pressure the more current the unit pulls..

Overall it does what I need and being portable I grabbed it out of the Garage and used it in the house bedroom one summer night and day.. when lightning blew up the substation... im sure the neighbors didnt appreciate my Bus running outside the house.. but then everyone else had noisy harbor freight gennys and whole house generacs going...

there is another product out which I havent bought one of and im guessing is a straight on / off compressor (but I dont know)..

ClimateRight 10000 btu Air Conditioner & Heater

its designed for teardrop campers... the 2 round holes are your actual conditioned air.. so this might be able to be mounted nicely under a bus and then run 2 insulated ducts in.. I havent tried it so i dont know if it is any good or not.. its less $$ than a climax and since its main gear is outside, doesnt use any interior space.. and it heats...

I may try one at some point just to see..
