Turning window ac on its side

My windows crank out and I have a couple portable window air conditioners. I was going to buy a portable one with or without the exhaust pipe. My neighbor stopped over and he said to just give it a quarter turn and put in the window. Block the space above the a/c.
His son has one running this way for 3 years. Just does not seem right. Does anybody have an idea if this would work without ruining the a/c.
The guy is pretty bright an usually has good advise.
 
If he is talking of turning it in the side, It won't work very long. The oil in the compressor will be away from the bearings and may get sucked into the compressor valves breaking them or locking up the compressor. The condensate form the evaporator coil will run out in the floor or through the electrical parts. My two cents. DH
 
No, they won't work on their side. The portables, with the exhaust hose, are horribly inefficient.

Since you already have the regular window units, why not just do a through the wall installation?

Or, get a split unit. The compressor (heat and noise) go outside, the evaporator goes inside. Only need a hole big enough for the refrigerant and drain line.
 
It might be worth looking into the small Mitsubishi split systems. I saw a display at Home Depot last week, so that would be a source.

You can get them as a heat pump, so you would have both heating and cooling. I understand that you can attach the outside compressor unit to other air handling systems inside the building. The only thing that goes through the wall is some lines and wires. Pretty neat installation.
 
Thanks for replies. Going to rule that idea out. I surely did not think that one through.
 
CAS,

You may not want to get the portable inside unit.

A couple summers ago, we bought two of them - thinking that would be the ticket! No more window installations!!

Long story short - we did not like them at all. They are noisy and the motor throws-off a lot of heat INSIDE your house. Not to mention the continual dumping of the moisture collection drawer - the units stop running... or switch to dehumidify mode when full of water.

We even set the units up high and had them drip into a bucket... we were literally pulling at least a 5 gallon bucket full of water out of the air EVERYDAY.

We used them one summer and gave them to our daughter and her husband.
 
I have anderson casement windows, crank out. There is a way to remove the window. That should give you more room for a small window unit, which most are around 15-17 inches wide.
 
I am very happy with my portable unit that I use in my camper.

All the heat and moisture goes out the exhaust tube that installs in the window.

It's not that noisy. I've slept with it running next to my bed several times when I was testing it out at home. No worse than the fan I usually run.

Yes, it's less efficient, but it's COOLER with it on than off. That's what's important.
 

Look into the mini-splits. My buddy who installs them says they use a lot less electricity than window units.
 
We have one of the portables with the exhaust hose except we specifically found one with TWO hoses. One of the hoses is designed to actually push the motor heat and humidity out separate from the heat from the room that goes out the other tube? Works excellent. But you take up floor space with it too, and it cost way more than the one-tube units.
 
Would you lay your refrigerator on it"s side and expect it to run ok? Think about where the compressor oil goes when it is on the side.

You can get an A/C unit for casement windows. Don"t buy a used car or anything mechanical from the neighbor.
 
I put an addition on my home about 5 years ago and installed a Mitsubishi split system in for heating an cooling. These little units are great. The system I installed required one 15 amp 240 volt circuit which powers both the inside and outside units. You run your 240 volt circuit to the outdoor unit and there is only control wiring to the indoor unit, which is installed with the bundle containing the refrigerant lines and drain hose. The thermostat is a remote control, which you can mount in a holder on the wall or just leave laying on a table. The unit scans the room looking for warm/cold spots and the louvers adjust to distribute tempered air where needed. And at times when power is out and I am running on the generator, I have 560 sq ft of heated/cooled space.
