Invisible comfort, Hitachi performance by AirGreen

At AirGreen , we believe that true comfort is not limited to a simple feeling of warmth or coolness: it translates into a balanced, quiet and healthy atmosphere, where every detail contributes to the serenity of the home.
This is precisely the experience offered by the Hitachi 12,000 BTU ducted heat pump , a sleek and powerful HVAC solution that combines cutting-edge technology , invisible design , and exemplary energy efficiency .

Designed to blend seamlessly into modern homes and spaces where aesthetics are essential, this heat pump represents the best of both worlds: world-renowned Hitachi power and local installation expertise from AirGreen , present throughout Montreal, Laval, Longueuil, the North Shore and the South Shore .


Ducted technology: comfort without visual compromise

The 12,000 BTU ducted model is part of Hitachi's airHome Multi line, a series of HVAC systems designed to deliver tailored comfort to multiple areas of a home from a single outdoor unit.
Up to five indoor units can be combined and installed in different rooms—bedrooms, living room, basement, office, or open plan—while allowing independent control of temperature, airflow, and operating mode.

The ducted unit, hidden in a false ceiling or partition, diffuses a uniform temperature through discreet vents.
Result: no visible devices, no intrusive noise, no aesthetic compromises.
It is the preferred solution for homeowners who want a perfectly uniform climate without altering the interior design of their home.


Exceptional performance, even in the heart of the Quebec winter

The Hitachi 12,000 BTU Ducted Heater is built for the Quebec climate. Thanks to its DC inverter technology and latest-generation compressor, it maintains a stable heating capacity down to -20°C , ensuring your comfort even during periods of extreme cold.

Its performance ratings— SEER2 of 18.0 and HSPF2 of 9.5 —illustrate its remarkable efficiency.
In concrete terms, this means reduced energy consumption throughout the year and a tangible reduction in your heating and cooling costs .

In addition, it uses the environmentally friendly R-32 refrigerant , known for its low global warming potential. This technological choice demonstrates Hitachi and AirGreen's commitment to combining innovation and environmental responsibility .


Purified and constant air quality

Thermal performance is only part of the equation: the air we breathe plays an equally essential role in home comfort.
This is why the Hitachi ducted heat pump incorporates a range of advanced purification technologies:

  • PM2.5 Activated Carbon Filtration : Captures up to 99% of fine particles, pollen, dust and fumes, while neutralizing odors and volatile organic compounds.

  • ViroSense S Filter : an innovative device that blocks the growth of mold and inhibits the proliferation of 99% of bacteria and viruses, for healthier air, day after day.

  • FrostWash™ Technology : An intelligent self-cleaning system that freezes, rinses and dries the internal coils, effectively removing impurities and maintaining long-term system performance.

  • Mold Guard function : after each cooling cycle, the system automatically activates an internal drying of approximately 60 minutes to prevent the formation of humidity and odors.

Thanks to these technologies, your home benefits from pure, fresh and safe indoor air , without additional maintenance effort.


Absolute silence and homogeneous diffusion

One of the great advantages of the Hitachi Gainable 12,000 BTU is its exceptionally quiet operation .
With an interior noise level as low as 30 dB(A) , it is literally forgotten.
Whether you're working from home, sleeping peacefully, or enjoying a movie with your family, you'll be in total sound comfort .

The system also diffuses the air evenly and gently , avoiding the sensation of drafts and temperature variations.
Each room remains at the ideal temperature, throughout the day and night.


Smart connectivity: control at your fingertips

With the optional airCloud Go adapter, the Hitachi ducted unit becomes a connected heat pump .
From your smartphone, you can:

  • Control the temperature of each zone independently.

  • Schedule time slots according to your habits.

  • Activate smart economy modes , which adjust power based on the presence in the room.

  • Check your energy consumption to better manage your electricity costs.

This intelligent approach transforms the Hitachi into a true home comfort assistant , capable of adapting to your lifestyle.


Built to last: Hitachi's signature robustness

Every component of the Hitachi ducted heat pump has been designed to withstand the most demanding conditions.
Sustainability is an integral part of its design:

  • Anti-corrosion exterior casing and anti-rust paint for better resistance to Quebec winters.

  • Anti-corrosion Blue Fin fins extend the life of the heat exchanger.

  • Flame retardant electrical enclosure for added safety.

  • Surge and frost protection , ensuring reliable operation year after year.

  • Built-in R-32 refrigerant leak sensor , with light and sound alarm, ensuring safe operation at all times.

This combination of protection and performance makes the Hitachi Gainable a durable solution, backed by a 10-year manufacturer's warranty on parts and the compressor .
