Our take on the Hisense 12000 BTU UltraSlim Window Inverter

The Hisense UltraSlim is a 12000 BTU window air conditioner with an inverter compressor, built to cool rooms up to about 550 sq ft. Its slim 20.3-inch-wide cabinet fits narrower single-hung windows than most 12,000 BTU units, and Wi-Fi plus the remote let you control it without leaving the couch. The inverter compressor runs at variable speed, so it holds temperature steadier and draws less power than a fixed-speed unit once the room is cool. It suits renters and owners who want a smart, quiet-ish window unit without cutting a wall, though it cools one room only and offers no heating.

Questions and answers

Is the Hisense 12000 BTU UltraSlim good for a bedroom?
Yes for rooms up to about 550 sq ft. The inverter keeps temperature steady, but light sleepers should note some owners find it audible at night.
Does it heat as well as cool?
No. It is cooling only, so you need a separate heat source in winter.
Will it fit my window?
The cabinet is about 20.3 inches wide and 14.6 inches tall, so it suits many narrow single-hung windows. Measure your window opening and check the installation kit before buying.
Does it work with a smart home system?
It has Wi-Fi and works through the Hisense app and voice assistants. Setup is the weak point; some owners report pairing trouble.
How is it different from a standard 12000 BTU window unit?
The inverter compressor varies speed instead of cycling on and off, which means steadier cooling and lower running costs. The trade-off is a higher upfront cost and more electronics that can fail.
What comes in the box?
The unit, a remote control and the standard window mounting kit with support brackets. Check the listing for the exact bracket style for your window type.
Where is the Hisense 12000 BTU UltraSlim Window Inverter cheapest?
At Quill, for $559.00, as of our latest check.
Where can I buy the Hisense 12000 BTU UltraSlim Window Inverter?
