Quick answer
The outdoor unit that releases or absorbs heat via refrigerant.
The condenser is the outdoor cabinet of a split system. In cooling, it releases the heat pulled from inside; in a heat pump's heating mode, it absorbs heat from outdoor air. It houses the compressor, the outdoor coil, and a fan. Keeping it clear of debris protects performance.
Why Condenser (Outdoor Unit) matters
