Ductless Bedroom Air Conditioner 4-in-1 Cooling Heating Ventilating
Quiet enough to run all night long
This ductless wall-mounted air conditioner combines four functions in a single unit: cooling, heating, ventilating and dehumidifying. In a bedroom, noise matters just as much as temperature — a device that hums or clicks can keep you awake just as easily as the heat itself. This unit runs whisper-quiet, so you can leave it on while you sleep without a second thought. Thanks to its wall mount, your floor stays clear, even in a narrow bedroom or under a sloped ceiling. With the timer of up to 8 hours, the unit runs for exactly as long as you sleep, then switches off on its own.
Why this unit works so well in a bedroom
- Whisper-quiet operation: no droning fan housing or clicking compressor next to your bed.
- Timer up to 8 hours: runs through your night and shuts off after, so you never have to wake up to turn it off.
- Dehumidifying: pulls damp air out of a warm bedroom, making the same temperature feel lighter.
- Cooling and heating: handy on a sweltering August night and on a chilly March morning alike.
- Wall mount: keeps the floor clear, so there's nothing to trip over at night.
- LCD display: read the settings without switching on the main light.
Built for warm bedrooms and attic rooms
A bedroom under the roof soaks up heat all day and barely cools off at night. By three in the morning the room can still sit around seventy-seven degrees Fahrenheit, and opening a window at that point mostly just lets in street noise. This wall unit tackles the problem with simultaneous cooling and dehumidifying, exactly the combination that makes an attic room livable. It also suits a guest room, dorm room or home office where there's no room for a floor-standing unit. More and more people are choosing this option before committing to a full system with an outdoor unit. Availability is limited during the summer months.

Every piece is made from carefully selected materials. Please follow the care label inside the garment. As a rule of thumb: wash knitwear cold and dry it flat, and have tailored outerwear professionally dry cleaned to keep its shape for years.
