The outdoor condenser unit of a split-type aircon requires adequate clearance on all sides to allow proper airflow and heat dissipation, which is essential for the unit to operate efficiently and avoid overheating. As a general guideline, there should be at least 20 to 30 centimeters of clearance on the sides and rear of the unit and at least 50 centimeters to one meter of open space in front of the unit where air is expelled. Placing the outdoor unit in an enclosed space, directly under sunlight without any shade, or near heat-producing equipment significantly reduces efficiency and shortens the lifespan of the compressor, so choosing a well-ventilated and accessible location is important during planning.
