Yes, but do you have a Subaru to tow it?

Anyone use a window AC sideways?

I'm more of a hardest way possible for little to no actual gain.
A mini split has it's own problems to address mainly the size of all the components.
It was just something I want to do... The midea units are really like mini splits, the indoor/outdoor units are just connected by copper line and wires as you can see in the pic above. So mounting the inside unit above my bed in the somewhat under utilized cabinet seemed like a easy thing to do.
Likewise putting the condensor in my "un-used" generator compartment seemed pretty easy.
Good to know, I haven't cracked any of them open, didn't realize that brands design was unique

I should be more specific, its a U shape which i guess is better but to me it just lends itself more to a "split" conversion.

5th wheel roof unit doesn't cut it when it gets in the 90s, windows are either wide enough but not tall enough or tall enough but not wide enough. Trying to keep from looking trailer trash in the RV park, I have been looking at truck 12 volt minisplits

This, my window unit has a condensate drain. If you mount it sideways all that water would just collect on your window sill.The condensate drain
Use a mini split!!

had same issue in my garage, pulled the window out, replaced with a window heat/ac unit, filled the space above it with a lexan panel
most of them these days have done away with the condensate drain and are using the fan to spit that back onto the condenser.
but yeah.

This was the inspiration for my diy window unit mini split idea. They are pricey and hard to find.

I run those in my house, they kickass. Costco recently had the 12k on sale for 279Ive been wanting to convert a Midea U air conditioner for my bedroom in my RV.

What specifically? Other than condensate drain, it seems like it should be minimal impact. Motors, electronics, etc. shouldn't care. Gas flow should be unaffected. No oil sump to worry about. Liquid flow in the evap/reciever is about all I can think of as a potential issue.

Try it and report back. 🤷
I had a friend who did the same thing; it worked for at least a couple summers.

Dude probably plugged it in before the oil all settled to somewhere dumb and didn't turn it off all summer.

I was thinking it was like a perfect storm, he put it on its left side, not the right, and that window happened to be 9 degrees out of level and it was rocked back/ falling out the perfect amount that it didn't eat itselfDude probably plugged it in before the oil all settled to somewhere dumb and didn't turn it off all summer.

You mean condensation won’t hit the pan and it’ll run water, and you may have oil issues.???!

Maybe you can twist the important bits 90° in the case and pop another hole in it for drain?

My grandmother's house is a ranch style with radiant heat and the sideways slide windows. For the main part of the house we bought a 12K wall unit with a slide in cage. We just cut a hole in the wall, framed it out and screwed the cage into the wall and slid the unit in. For each of the bedrooms we bought the smaller 5K window units and had the local glass shop make double pane panels to go above them. We framed out the openings with 1x trimmed for the width of the glass and window frame and the u channel on top of the AC and sandwich them all together. We have had to replace each unit once but it's been like that for 16 years

I’m in Georgia , it’s been between 90 and 98 every day for the last two weeks .
Usually with humidity above 90% too .
Just spent a week at 4100 feet elevation in western NC and me and my asthma are ready to move .
Was 61 at night and 75 during the day with hardly any humidity .

Well yeah on its side there will be zero drain pan to direct the water.
No idea on the oil but it would be a problem if it ended up some where it shouldn't.
But IMO the initial problem is going to be the water fall in the bedroom.
This week is the first time I've been home for more than 4 days in 6 months.
Work is in Florida.
I have determined I like the North.

ugh, that guy again?
hermetic ac compressors are very much built to be run in one orientation. They've only got one bearing in between the motor and pump (instead of having both ends of the rotor supported), the oil pump in the compressor is really just a wobbly tube that dips in the oil and 'pumps' through slinging/scooping oil into itself.

he should put the capillary tube at the condensing unit end like it is in a minisplitIve been wanting to convert a Midea U air conditioner for my bedroom in my RV.

the boiling refrigerant is actually pretty darn loud, and the lost efficiency isn't all that huge so long as you can insulate the lineset.
While you're in there you may as well add in a suction line heat exchanger and gain back all your lost efficiency plus a bit.

You found my weakness, I am HVAC functional but I have not done it enough to get balls deep in theory.

Just one of another thousand things that interested me for long enough.
My cert's only good for systems up to 8lbs of refrigerant, but I'm sure I could get the unrestricted one easily enough

It's all googleable pretty easy
suction line heat exchanger is something that takes the liquid line and cools it off after the condenser and before the expansion device using the cold suction line gas before it goes into the compressor
it makes it act like the condenser is colder than ambient temperature, so you get more snoots for your schnozz
The downside is a little less compressor cooling (but it'll live, peel the noise insulation off the compressor and it'll radiate heat better), and a bit more copper in the system.
