The condenser units primarily feature an outer housing, a compressor, heat exchange component, and a fan/motor assembly. Condenser units with heat pumps are used in an AC system that cools and heats. The condenser units are said to be incomplete and once imported, a filter, a solar panel, a Variable Frequency Drive, pressure sensors, and additional electrical controls that operate the condenser unit are installed onto the condenser unit.
