    Overview

    The Westinghouse WWH39CWA delivers powerful, reliable cooling in a compact, all-in-one design—ideal for medium-sized rooms such as bedrooms, offices, or living areas. With 3.9kW of dedicated cooling capacity, it efficiently cools areas up to approximately 15m². Its integrated window/wall configuration makes installation straightforward and avoids the complexity of split units.

    Equipped with an LCD remote control, the WWH39CWA provides easy access to four adjustable fan speeds—Eco, Low, Medium, and High—plus Auto Swing louvres for even air distribution. Additional modes such as Sleep, Timer, and Auto Restart enhance energy efficiency and comfort. A Fresh Air Intake helps ventilate and reduce humidity, while a removable dust filter supports healthier circulation.

    Gold Shield corrosion-resistant heat exchangers—both external and internal—ensure long-lasting performance in challenging environments. With sturdy build and user-centric features, this model is a dependable solution for effective, no-fuss cooling in everyday Australian homes.
    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.

    Manual Dial Controls

    Operate your air conditioner directly using intuitive mechanical dials. Easily adjust fan speed and temperature settings without requiring a remote—ideal for users who prefer simple, no-fuss functionality.

    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.
