Hisense 12000BTU Wall Split Air Conditioner with WiFi Inverter, Model AS-12TW4

Our review

This Hisense unit is a 12000BTU wall-mounted split air conditioner with WiFi inverter control, designed for fast cooling while keeping power use down. The inverter compressor adjusts its speed instead of switching on and off constantly, which is where most of the energy saving comes from, and the R32 refrigerant is the newer, lower-impact option. It suits a bedroom, small living room or office where quiet running matters, and the WiFi control helps if you want to cool the room before you arrive. Before buying, check the room size and ceiling height against the 12000BTU rating, confirm your wall has a suitable spot for the indoor unit and a route for the outdoor unit, and ask about installation, since split systems need proper mounting and pipework. Compare it with non-inverter 12000BTU models, which usually cost less upfront but draw more power, and with units that lack WiFi if you don't need app control. Available on Sokonia.
