A wind baffle is a metal shield installed on the outdoor unit to prevent strong winds from interfering with the fan's operation or the defrost cycle. This is especially important for heat pump systems located in high-wind coastal areas or on rooftops. By maintaining consistent airflow, the baffle ensures the system can heat and cool efficiently even during a storm. Many of our Cooper&Hunter units can be fitted with these for improved low-ambient performance. If you are installing a multi-zone system in an exposed location, a wind baffle is a smart addition. You can find these specialized parts in our accessories catalog.
