Morphology

air + condition

The meaning 'a system for controlling the temperature, humidity, and ventilation of indoor air' is directly derivable from combining 'air' with 'conditioning' (to render into a desired state): conditioning applied to air naturally yields making the air comfortable. This compositional logic is cross-linguistically common (e.g., Spanish 'aire acondicionado', French 'climatisation'), so a B1 learner who knows both constituents will readily infer the MWE's meaning.

Etymology

Air conditioning comes from the idea of changing the state of indoor air: early machines were said to 'condition' the air by cooling it and removing moisture. So, air conditioning now means a system that cools and makes indoor air comfortable.
