Origin: Formed within English, by compounding. Etymons: air n.¹, conditioning n.

Etymology: < air n.¹ + conditioning n. (compare quot. 1909). Compare air conditioner n. and later air-condition v., air-conditioned adj.

Now usually: the process of controlling the humidity, ventilation, and air temperature in a building, vehicle, etc., esp. to maintain a comfortably cool atmosphere in warm conditions; (also) an installation or appliance which performs this process, an air conditioner.
