I’m living in Shenzhen, People’s Republic of China. I live on the 9th floor of our 34 floor apartment building, and just had to have our external air conditioning serviced. I was alarmed and amazed as our air conditioning technician tied a rope around himself, and then went out the window to the external air conditioning unit to give it a dose of freon (as I held the rope!). My gf asked, what do they do in the USA?
In the USA buildings have central Air-Conditioning and the equipment is usually located on the roof of the building.
They are usually located on the roof tops.
