Portable room AC

And how would you vent it?

2016 -- A/C are not that complex. your tech needs to go back to school..

good luck

You have to vent and AC. That would be problematic with a trailer.

I always thought one of these would be pretty neat...

Simple to vent one through the floor or window. They are not as effective as window or top mounted units since they draw hot air into the trailer to replace what is vented out. Two hose models are much better.

That's exactly the problem with those. They draw in the same amount of air that they exhaust, which is going to be hot air from outside.

I had one in my small office space in my shop. I sold it on Craigslist after 1 summer of usage.

I made one work very well in a cargo trailer. I ran a duct for replacement air to the back of the machine. Only cool air went out into the trailer and warm air came in the rear corner and out the floor. Easy in a cargo trailer.

Dual hose or forgetaboutit.

I bought one with just one hose for my moms 1200 sq/ft house. The house had no insulation in the walls/floors and only 3" in the attic and leaky, single pane windows. The unit was 12K btu.
I was shocked how well it worked. The AC had no problem cooling the living area's of her house even when she waited until it was hot to turn it on.
So yea, form our experience they work well.

Used the dual hose models at several clients to keep a rack or so of computer equipment cool (~3kw or 10k BTUs), they worked well. You will need to either empty the drip pan on a regular basis or get a condensate pump and run a line out the window (I always told clients not to be cheap on the pump but as a backup for a normal unit your probably fine with anything as you won't be running it much, hopefully)
