Things to consider
It is a cool-only non-inverter model with a 1.5-star cooling rating, so buyers wanting quieter operation or stronger energy performance may prefer a more premium alternative.
Apartment cooling suitability
Good for small apartments or single rooms where a compact window or wall-mounted cooling solution is needed.
Diy installation friendliness
Moderate - box air conditioners can suit replacement installs, but window or wall fitting usually benefits from professional installation.
Noise level vs category
6/10 - indoor noise of 50 dBA is typical for a box air conditioner, but not as quiet as premium split systems.
Energy efficiency score
4/10 - 1.5-star cooling rating is serviceable for basic use but below more efficient alternatives.
Key benefits
- 3.9 kW Cooling Capacity: Effectively cools small to medium rooms sized around 20 to 35 square metres.
- LCD Remote Control: Lets you adjust settings from across the room without needing to reach the unit.
- Four Fan Speeds: Gives you eco, low, medium and high airflow options to better match changing comfort needs.
- Fresh Air Return: Adds extra ventilation to help keep the room feeling less stale.
- Sleep Mode: Supports more comfortable overnight use with a setting designed for night-time operation.
- 12-Hour Timer: Helps automate start and stop times to better fit your daily routine.
- Maximum Airflow 2304 m3/hr: Delivers strong air movement to help distribute cool air through the room.
- 1.5-Star Cooling Energy Rating: Provides basic cooling efficiency for buyers prioritising upfront value over higher-rated performance.
Q: Is this air conditioner suitable for a bedroom at night?
A: Yes. Westinghouse WWH39CWA includes Sleep Mode and the indoor noise level is 50 dBA, which can suit many bedrooms. It is still a box air conditioner, so it will be more noticeable than quieter split-system options in a very noise-sensitive room.
Q: What does the fresh air return do on this model?
A: Fresh air return lets the unit bring in some outside air while it is cooling, which can make the room feel less closed in. It is an added ventilation feature, not a full replacement for opening windows or using dedicated whole-room ventilation.
Q: Can I control the WWH39CWA from my phone or Wi-Fi?
A: No. Westinghouse WWH39CWA is not Wi-Fi enabled, so it cannot be controlled from an app or added to smart-home routines. Control is by the on-unit buttons or the included LCD remote, which suits simple in-room operation.
Q: How efficient is this box air conditioner for regular use?
A: Westinghouse WWH39CWA has a 1.5 star cooling energy rating in an average climate. A higher-starred window wall air conditioner can reduce running costs, so this model is better suited to buyers prioritising simple cooling over stronger efficiency.
Q: Does the Westinghouse WWH39CWA have inverter cooling technology?
A: No. Westinghouse WWH39CWA is a non-inverter box air conditioner, so the compressor does not modulate like an inverter model. It is built for straightforward room cooling rather than the smoother, more efficiency-focused operation buyers may expect from inverter units.
Q: Can the timer shut the unit off overnight automatically?
A: Yes. The timer can be set for up to 12 hours when you want a delayed shut-off overnight. That works well with Sleep Mode, but scheduling is done from the remote or on-unit controls rather than an app.
