  • Cools even large rooms with ease: At 12,000 BTU / 3.5 kW and energy efficiency class A, the Metrobreeze New York Smart 12k reliably brings rooms between 35 and 59 m² down to your chosen temperature — efficiently and consistently.

  • One compact unit, every climate need covered: Air conditioner, fan, and dehumidifier are all built into a single compact unit, so you can tackle whatever the weather throws at you without cluttering the room with extra devices.

  • Quiet enough for a good night's sleep: At its lowest setting, the Metrobreeze New York Smart 12k runs at just 52 dB — quieter than a normal conversation — so it's perfectly suited to bedrooms, living rooms, and home offices day and night.

  • Up and running in minutes, wherever you need it: There's no fixed installation required — the telescopic exhaust hose and window seal mean you can have the unit cooling a room in minutes, and move it wherever it's needed next.

  • Control it from anywhere: Full Amazon Alexa and Google Home compatibility means you can adjust the temperature, change mode, or set the timer by voice. The Klarstein app via Wi-Fi gives you the same control remotely — from the office, on the way home, or without leaving the sofa.

Product description

Summer in the UK might not be scorching every day — but when a heatwave hits, it hits hard. The Klarstein Metrobreeze New York Smart 12k is built for exactly those moments: powerful portable air con that cools rooms up to 56 m², ready to use straight out of the box, no installation required.

With 12,000 BTU / 3.5 kW of cooling power and an energy efficiency class A rating, the Metrobreeze New York Smart 12k handles generously sized living rooms, bedrooms, and home offices between 35 and 59 m² without breaking a sweat. You can dial the temperature anywhere between 17 and 30 °C, and at its quietest the unit runs at just 52 dB — below the level of normal conversation, so it won't disturb a light sleeper.

This isn't just an air conditioner. The Metrobreeze New York Smart 12k also works as a fan and a dehumidifier, covering all three bases in one compact unit. Control it however suits you — via the Klarstein app over Wi-Fi, the included remote, or the buttons on the unit itself. Amazon Alexa and Google Home are fully supported, so you can adjust temperature, switch modes, or set the timer with a voice command from the sofa — or from the office before you head home. The 24-hour programmable timer means your home can be at the perfect temperature the moment you walk through the door. The telescopic exhaust hose with window seal gets you up and running in minutes without any work on the fabric of the building. The refrigerant used is R290 (245 g), which has a low global warming potential.

Whether it's the bedroom during a heatwave, your home office on a sweltering afternoon, a holiday let, or a workspace that's simply too warm, the Metrobreeze New York Smart 12k delivers flexible, serious cooling wherever you need it — with smart controls that keep up with your life.

Stay cool this summer — order the Metrobreeze New York Smart 12k today and have it working before the next hot spell arrives.

The build quality is excellent, and I love that it connects to a mobile phone. I did encounter one issue with the app: when I try to change the mode through my phone, it doesn’t actually switch. However, that’s not a big deal for me. The cooler came with a set of accessories that allow you to secure an open window, which is a great feature. The only downside was the shipping, it took about 10 days for the package

Un peu bruyant en mode « high » mais en vrai elle fait un travail de dingue !! En 10min je peux perdre 2 degrés dans mon salon. Elle refroidit notre salon de 20/25m2 + petit couloir de 1/2m2 + cuisine de 11m2 donc vraiment les 12.000btu sont fiable. On reprendra la même pour les chambres à l’étage, vraiment top pas déçus de notre achat ! Aujourd’hui il a fait 21 grâce a la clim contre 31 degrés dehors !

Que le climatiseur fonctionne très bien.fait un peu de bruit,mais cela reste correct.

Verified review 16/07/2025

A funcționat bine in primul an. Când să îl pun la treabă în iulie 2025, am observat că s-a transformat într-un simplu ventilator. Nu mai baga aer rece. Surpriza mare a fist că trebuie să îl împacheteaz și să îl trimit înapoi pentru garanție. Nu au posibilitatea să rezolvi local cu garanția. O mare problema.

Macht was er soll, kühlen und das sehr gut.

Verified review 01/07/2025

Super Klimaanlage kühlt den Raum auch wirklich runter und ist halt leider auch nicht die leiseste aber sie muss ja auch kühlen und der Kompressor kann nun mal nicht leise sein! Kann die schlechten Empfehlung der Klimaanlage überhaupt nicht nachvollziehen! Auch funktioniert die App absolut tadellos! Absolute Kaufempfehlung
