TL;DR
The outdoor unit is the half of a split-system air conditioner or heat pump that lives outside, housing the compressor, the outdoor coil, and the fan that moves air across it to reject or absorb heat. Placement affects performance and neighbors: clearances per the manufacturer, elevation above snow depth for heat pumps, and distance from bedroom windows for noise.
