Condenser (Outdoor Unit)
The outdoor half of an AC or heat pump, where refrigerant releases (or in heating mode, absorbs) heat. It houses the compressor, outdoor coil, and fan. Keeping it clear of leaves and shrubs protects airflow and efficiency.
The longer answer
In cooling mode, the condenser rejects heat to outdoor air; in heating mode, it absorbs heat from outdoor air (even cold air contains extractable energy — that's the heat pump principle). Restricted airflow from debris, fencing, or tight placement raises head pressure, cuts capacity, and shortens compressor life.
Placement matters in dense Seattle neighborhoods: side yards, rear patios, and wall brackets all work, but the unit needs clear airflow on all sides and a level pad with drainage. Line-set length and height limits from the manufacturer constrain how far the condenser can sit from indoor heads or the air handler.
The Seattle angle
Seattle's tree canopy and wet climate mean condenser coils clog faster than drier regions — annual coil cleaning is standard maintenance-plan scope on Elite, and worth doing before every cooling season regardless.
