    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.
    Quick, Easy Climate Control

    Enjoy reverse cycle air conditioning without complex installation. Window/wall units offer a practical solution for fast comfort, and some models are so straightforward you can even handle the install yourself.

    Efficient All-in-One Design

    With no separate indoor or outdoor units, these models simplify setup and operation. As a trusted Westinghouse appliance, you can expect dependable, long-lasting performance for year-round use.

    Convenient Remote Operation

    Adjust temperature, fan speed, and settings from the comfort of your couch. The full-function remote control puts effortless climate control right in your hands.

    Enhanced Air Quality & Ventilation

    A fresh air intake adds circulation while helping to manage humidity levels. The built-in dust filter captures larger airborne particles for cleaner, more breathable indoor air.
