At a glance
This 3.9 kW Westinghouse window wall air conditioner is a practical cooling option for small to medium rooms, especially bedrooms, living areas and home offices. It offers simple remote operation, multiple fan speeds, fresh air return and handy sleep and timer functions. Its main strength is straightforward room cooling in a compact format, but it is cool-only, so it does not provide heating for year-round climate control.

Things to consider
This model is designed for cooling only, so buyers wanting winter heating or stronger efficiency than a 1.5 star cooling rating may prefer a reverse-cycle or more premium alternative.
Apartment cooling suitability
Well suited to apartments or units with a compatible window or wall opening, especially for cooling bedrooms and living spaces without installing a separate outdoor unit.
Diy installation friendliness
4/10 - box air conditioners usually need secure fitting into a window or wall opening, so installation is less straightforward than portable units.
Noise level vs category
5/10 - likely typical for a box air conditioner, but generally not as discreet as many split-system alternatives.
Energy efficiency score
4/10 - the 1.5 star cooling energy rating suggests modest efficiency compared with stronger-rated alternatives.
Key benefits
- 3.9 kW Cooling Capacity: Delivers solid cooling performance for small to medium rooms around 20 to 35 m².
- LCD Remote Control: Lets you adjust settings from across the room for more convenient day-to-day use.
- Four Fan Speed Settings: Gives you eco, low, medium and high airflow options to better match changing comfort needs.
- Fresh Air Return: Helps bring in additional ventilation for a less closed-in room feel.
- Sleep Mode: Supports more comfortable overnight use by simplifying nighttime cooling management.
- 12-Hour Timer: Makes it easier to schedule cooling around your daily routine and shut-off times.
- Compact Box Design: Fits neatly into suitable window or wall openings where a split system may not be practical.
- 1.5 Star Cooling Energy Rating: Provides a clear benchmark for cooling efficiency in average Australian climates.
Q: What room size is a 3.9 kW box air conditioner usually suited to?
A: A 3.9 kW cooling capacity is typically suited to a small to medium room of about 20 to 35 square metres. The better fit depends on ceiling height, insulation, sun exposure and how much heat the room picks up during the day.
Q: Does the Westinghouse cool only design mean it cannot be used for heating?
A: Yes. This is a cool only box air conditioner, so it is designed to lower room temperature in warm weather and does not provide reverse-cycle heating. If winter heating matters, a heating and cooling model is the better match.
Q: What should I check before replacing an older box air conditioner with this Westinghouse unit?
A: Check the existing wall or window opening size, the cabinet depth and whether the structure can support the unit. Box air conditioners are not as flexible as portable models, so a close fit matters for airflow, sealing and stability.
Q: Is a box air conditioner like this usually louder than a split system?
A: Yes. A box air conditioner usually sounds more noticeable than a split system because the compressor and fan are housed in the same unit. It can still suit bedrooms or living areas, but noise sensitivity is worth weighing before buying.
