Westinghouse split system
The main feature I like about this product other than the heating and cooling efficiency is that it’s wifi connected and pairs perfectly with Google home. This means 3 methods of operation

At a glance

It suits households wanting year-round comfort and app-based convenience. Its main limitation is that it focuses on practical features rather than the quieter operation or deeper smart ecosystem support found in more premium models.

Things to consider
While it offers Wi-Fi control and good filtration, it may not match premium split systems for advanced smart home integration, ultra-quiet performance or specialised air purification features.
Room size suitability
Medium to large rooms of approximately 35 to 50 square metres
Energy efficiency score
8/10 - 4 star energy rating for both cooling and heating in average climates supports strong everyday efficiency
Noise level vs category average
5/10 - no specific low-noise claim is provided, so it appears more standard than especially quiet
Smart home integration score
7/10 - Wi-Fi app control adds useful convenience, though no broader voice assistant or ecosystem support is specified
Allergy friendliness
8/10 - multi-stage filtration with Biofresh, HEPA, dust and ion filters makes it a strong option for households prioritising cleaner airflow
Key benefits
- 5.1kW Cooling Capacity: Provides effective cooling performance for medium to large rooms, making it well suited to everyday living spaces.
- 6.1kW Heating Capacity: Delivers strong reverse cycle heating for comfortable winter use in the same room sizes.
- Wi-Fi Connectivity: Lets you adjust settings remotely through the +home app for added convenience around the home.
- Remote Control Included: Makes quick temperature and mode changes easy without needing to use the indoor unit directly.
- Multi-Stage Filtration: Uses Biofresh, HEPA, dust and ion filters to help maintain cleaner airflow indoors.
- DC Inverter Compressor: Adjusts output smoothly to help maintain a more consistent indoor temperature.
- 24-Hour Timer: Helps you schedule operation to better match daily routines and comfort preferences.
- 4 Star Energy Rating: Delivers 4 star cooling and 4 star heating performance in average climates, giving it solid energy efficiency for its class.
Q: What size room is the Westinghouse WSD51HWA best suited to?
A: This 5.1kW cooling and 6.1kW heating split system is typically suited to a medium to large room, around 35 to 50 square metres in many Australian homes. Ceiling height, insulation, window area and sun exposure will still affect performance.
Q: What does Follow-Me do on the Westinghouse WSD51HWA?
A: Follow-Me uses the temperature sensor in the remote so the unit can adjust output based on where the remote is placed, not just where the indoor unit is mounted. That can help if seating or sleeping positions are away from the wall unit.
Q: Does the wireless connectivity on this Westinghouse split system let you control it remotely?
A: Yes. The wireless connectivity is designed for remote control, so you can adjust settings without standing at the unit. It is useful for pre-cooling or pre-heating before arriving home, provided the unit is connected to a compatible home network.
Q: Is the Westinghouse WSD51HWA a good option if air filtration matters?
A: It includes both a Super ion filter and a bio filter, which are aimed at reducing airborne particles and helping maintain cleaner airflow. It is a useful extra for everyday home comfort, but it is not a substitute for a dedicated air purifier.
Q: What does demand response capable mean on the Westinghouse WSD51HWA?
A: Demand response capable means this model is designed to work with eligible energy management programs that can reduce air conditioner load during peak demand events. Availability depends on your electricity provider and setup. Discuss with your electrician.
Q: How do the inverter compressor and DC fan motor help in everyday use?
A: They help the system adjust output more smoothly instead of repeatedly stopping and starting at full power. In practice, that usually means steadier room temperature, less temperature swing and better efficiency than older fixed-speed split systems.
