Can't comment on the technical aspects or performance for higher or lower but if not on ground recommend not less than 7 ft. Stayed for two months in one of the Australian villa jobies where ACs were sited on balconies approx 5 ft from floor suspended on sharp metal brackets. Still carrying the head wounds and probably brain damage ! Visitors similarly impaled. Units on floor must have obvious risks for the enebriated or children plus take up floor space which could perhaps be better utilised. Hope the technically knowledgeable can help you. Meantime take care, and don't get mashed, bashed or crashed !

I agree with msg 2

from technical view if the installer fit the outdoor unit above the level of the indoor unit and did not make a loop for the refrigerant pipes (usually at the same Height of the outdoor unit) oil will go down to the indoor causing functional problems .

Safe access is the issue. Not so high it is dangerous to work from a ladder (I know!), not so low that it can be a hazard or vandalized.

so its safe to say that if the outside unit is sitting on the concrete (damp proofing) that goes round the house, it would be OK providing it does not get in anyone's way, and that there would be no restrictions on the working of the unit..?

"on the concrete (damp proofing) that goes round the house" yeah that's a real joke. It causes damp by breaching the damp proof membrane if there is one!

msg 5,



Generally speaking, yes.

Very large systems, 24,000Btu and upwards, are too heavy really to mount on arms and it is safer to have them stood at ground level.

Jock. I think firstly it's to do with safety. Secondly it's probably something to do with it being as close as possible to the unit inside your property. (I'm probaby wrong )

Depending on the unit, indoor-outdoor seperation distances can be as low as 3m for cheap systems. Some Japanese systems have 25m or more.

you can place them indoor-outdoor (back to back ) but the refrigerant pipes must be at least 2m long

thanks Vaughan, to be honest it was a question that was asked to me by someone who wants it done, i have fitted many A/C's through out my time, but i was only asking to clarify with the person who wants it done.
