Welcome to the forum. Although you can post in any forum, the USA forum is here in case of local regs or laws

Air to air heating

Being older than most on here probably I can remember them being called "Split units" and then "Split unit Comfort cooling with heating" Air Conditioning was outside compressor and condenser units ducted into the building with ceiling mounted air distribution box's, seems that we have fallen into the Americanisms of calling everything Air Conditioning if it moves air with even a hint of changing it's temperature no matter where it is located.
 

We recommend City Plumbing Supplies, BES, and Plumbing Superstore for all plumbing supplies.
