The perfect combination of understated elegance and lasting performance

At AirGreen , we know that indoor comfort should never compromise the aesthetics of a space. The Hitachi Mini Ceiling Cassette 9000 BTU perfectly embodies this philosophy. Designed to provide an optimal climate all year round , it combines compact design, cutting-edge Japanese technology and remarkable energy efficiency—all backed by the installation expertise of AirGreen , master refrigeration engineers in Montreal, Laval, Longueuil, the North Shore and the South Shore.


A wall-mounted heat pump? No, a discreet and powerful cassette!

While most wall-mounted heat pumps are installed high on a wall, the Hitachi Mini Cassette fits directly into the ceiling. At only 22 x 22 inches , it fits easily into standard ceiling tiles, making it ideal for modern offices, retail spaces , or even open-plan residential spaces .

Its 4-way air distribution ensures a uniform temperature throughout the room, eliminating cold or hot spots. Whether you're in a conference room in Laval, a hair salon in Longueuil, or a condo in downtown Montreal, you'll enjoy consistent, even comfort .


Leading energy efficiency

With a SEER2 of 23.0 and an HSPF2 of 7.85 , this cassette is among the most efficient models in its category. In short:

  • It refreshes in summer with minimal consumption,

  • It heats efficiently in winter down to –20°C ,

  • And it significantly reduces your energy bills , while contributing to a greener environment thanks to its R-32 refrigerant, known for its low carbon footprint.

These performances are Energy Star (Cold Climate) certified, guaranteeing that the Hitachi Mini Cassette meets the requirements of provincial grant programs, including the LogisVert program , offering up to $1,920 in financial assistance for its installation.


Quiet, smart and connected

With an indoor noise level of only 27 dB(A) , this heat pump operates virtually silently — perfect for bedrooms, waiting rooms or work spaces.

It is also Wi-Fi compatible thanks to the airCloud Go adapter, allowing remote control via your phone. You can:

  • Schedule operating hours,

  • Adjust the temperature before your arrival,

  • Check your energy consumption in real time,

  • And even automatically turn off the device when no presence is detected, thanks to its integrated motion sensor .

It is a true smart heat pump , designed to optimize comfort and economy without constant user intervention.


Cleaner air for a healthier environment

Beyond heating and cooling, the Hitachi Mini Cassette acts as a complete air purifier . Its ViroSense S filter blocks 100% of mold and inhibits 99% of viruses and bacteria according to tests by the Kitasato Research Center of Environmental Science.

Added to this is Hitachi's signature FrostWash technology, which freezes and then melts impurities accumulated on the heat exchanger, automatically cleaning the unit and maintaining optimal air quality.

In other words: your heat pump self-cleans, disinfects itself and protects your health without any effort on your part.
