    Overview

    The Westinghouse WWH39HWA is a high-performance 3.9kW cooling / 3.6kW heating reverse-cycle air conditioner designed for year-round comfort in medium-sized rooms like bedrooms, home offices, or lounge areas. Its all-in-one window/wall mounting system simplifies installation—eliminating the need for separate outdoor units and minimizing visual impact.

    Featuring modern styling with clean lines and a sleek fascia, this unit includes a full-function remote control for intuitive adjustment. Auto Swing louvres ensure even airflow distribution, while Sleep Mode and a 24-hour timer offer energy-efficient, scheduled comfort. The Fresh Air Intake and easy-service dust filter improve ventilation and air quality.

    Durable Gold Shield heat exchangers—both internal and external—resist corrosion for long-term reliability in coastal or humid environments. Auto Restart capability guarantees your settings return after a power interruption, offering seamless return to comfort. Compact, efficient and user-friendly, the WWH39HWA pairs powerful reverse-cycle performance with thoughtful design for flexible climate control.
