Can I mount a room air conditioner in the floor (vertically)?

Question

Hi, folks; I'd like to install a room air conditioner in my crawlspace hatch in the floor rather than in a window. (This will eliminate burglary concerns in my 1st floor window, and also keep the aircon unit in the shade all the time.)

Is there any reason why this wouldn't work?

Is there an air-operated shutter inside room a/c that might hang open (by gravity) that would prevent me from mounting vertically? Are there other operational concerns with vertical mounting (like where the oil sits in the compressor?)

Thanks.

Answer 1

Sorry.  NO  NO  NO  NO!  AC units don't want to be verticle.  Ain't gonna happen.  If you need to, redirect the airflow, Don't stant the unit on it's side!

Answer 2

Air conditioners are in windows to allow the condensation that makes water to drip outside.  You will have a huge mess and ruin if you don't have an outside source to drain. It can also be a fire hazzard with your electrical wiring getting wet.

Answer 3

has was stated in the other answer it will drip water down which will short out the fan motor also the oil in the compressor bust be in the sump so it can lube the push rod journal or it will burn out

Answer 4

Definitely don't  mount it this way you will ruin it.The oil has to stay inside the compressor with it setting normally if you mount it this way you won't have to worry about water it won't run long enough to make very much.Service tec 17yr.
