  • Cools even large rooms reliably: With 12,000 BTU / 3.5 kW and Energy Efficiency Class A, the Metrobreeze New York Smart 12k brings rooms of 42–56 m² to your chosen temperature and keeps them there — without running up your electricity bill.

  • Heat, stuffiness, and damp — sorted in one unit: Air conditioner, fan, and dehumidifier are all built into a single compact machine, so you can tackle every aspect of indoor comfort without cluttering the room with extra kit.

  • Quiet enough for a good night's sleep: At its lowest setting, the unit operates at just 52 dB — well below the level of a normal conversation, making it perfectly suited to the bedroom or a quiet home office.

  • Ready and waiting when you walk through the door: The 24-hour programmable timer, adjustable in 1-hour increments, lets you schedule cooling in advance — so your home is already comfortable when you arrive back, without the unit running all day.

  • Control it from anywhere: Full compatibility with Amazon Alexa and Google Home means you can adjust temperature, change mode, or set a timer by voice or via the Klarstein app — whether you're on the sofa or still at the office.

Product description

Powered by 12,000 BTU / 3.5 kW and rated Energy Efficiency Class A, the Metrobreeze New York Smart 12k handles generously sized rooms of 42–56 m² with ease. Set your ideal temperature anywhere between 17 and 30 °C and leave it to get on with the job. At its quietest, it runs at just 52 dB — softer than a normal conversation, so it won't disturb your sleep or your concentration.

This is a proper 3-in-1 unit: portable air conditioner, fan, and dehumidifier, all in one compact machine. Control it however suits you — via the Klarstein app over Wi-Fi, with the included remote, or directly on the unit.

The 24-hour programmable timer means your home is already at the right temperature by the time you walk through the door. The telescopic exhaust hose and window seal mean you're up and running without touching the walls or window frames. The R290 refrigerant (245 g) has a low global warming potential.

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

L'esthétique est plutôt réussie, mais la qualité générale du produit laisse à désirer : des rayures étaient présentes à la réception, et le tuyau d'évacuation de chaleur est de facture moyenne, il se décroche au moindre déplacement de l'appareil.

Concernant les performances, la surface annoncée jusqu'à 56 m² est largement surestimée : en pratique, l'appareil peine à refroidir efficacement au-delà de 21 m², et encore moins par forte chaleur.

Enfin, le produit est annoncé comme silencieux à 65 dB. Après vérification au sonomètre, l'appareil tourne effectivement autour de cette valeur. Si vous êtes sensible au bruit, notamment pour dormir, ce climatiseur n'est probablement pas fait pour vous.

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
