An outdoor unit, also called a condenser unit, is the outside component of a central AC or heat pump system. It houses the compressor, condenser coil, and fan. The unit expels heat during cooling and absorbs heat during heating for heat pumps. Proper maintenance keeps the system efficient and extends equipment life.

Compressor, coil, and fan work together to move heat.
Outdoor units are often placed beside a home away from windows to reduce noise and are kept clear of vegetation for proper airflow.
Keep at least 2 feet of clearance around the outdoor unit and schedule regular cleaning and inspections.
“Keep at least 2 feet of clearance around the outdoor unit and schedule regular cleaning and inspections.”
Outdoor and indoor units must be properly matched in capacity and efficiency for best performance.
Can I cover my outdoor unit in winter?
For AC-only systems, a breathable cover can help, but heat pumps should not be covered while in use.
Why is my outdoor unit noisy?
Noise can come from debris, loose panels, or an unlevel pad. Maintenance helps reduce it.
