A discreet, high-performance HVAC system perfectly suited for residential and commercial needs across Greater Montreal
In the world of modern HVAC, the ceiling cassette has emerged as an increasingly popular solution for spaces where aesthetics, energy efficiency, and comfort go hand in hand. At AirGreen, we install this type of indoor unit in both residential and commercial projects throughout Montreal, Laval, Longueuil, the North Shore and South Shore, integrating it into heat pump and central air conditioning systems for maximum efficiency.
This technology provides even heating and cooling, all while remaining virtually invisible. In this guide, we offer a detailed overview of the benefits, technical features, configuration options, installation steps, and key considerations for a successful project.
What is a ceiling cassette?
A ceiling cassette is an indoor air conditioning or heating unit installed directly into a drop ceiling. Unlike a traditional wall-mounted unit, it is embedded and only a flat, discreet grille is visible, usually centered in the room.
Ideally used in open areas or high-traffic zones, it distributes air in four directions, ensuring an even temperature throughout the space.
Why choose a ceiling cassette?
Aesthetic and discreet
The ceiling cassette blends seamlessly into the environment without disrupting interior decor. With only a subtle grille showing, it’s a perfect fit for offices, retail spaces, modern apartments, and upscale homes.
Optimal comfort
Thanks to its multi-directional airflow, the temperature remains balanced throughout the room, with no unpleasant drafts. It’s particularly recommended for large open spaces, meeting rooms, or commercial areas.
Energy efficiency
The latest cassettes installed by AirGreen are compatible with high-efficiency inverter systems, such as the FUJITSU R-32, Bosch BOVA, or Gree U-Match models, which reduce energy consumption and extend the life of the system.
Quiet operation
Many of our clients are looking for a calm, peaceful environment—at home or at work. Ceiling cassette units are among the quietest on the market, with noise levels as low as 27 dB, depending on the model.

An AirGreen installation: real-world example in Montreal
We recently installed a Gree 24,000 BTU ceiling cassette in a conference room of an administrative building located in downtown Montreal. The main challenge? Fitting the unit into an existing drop ceiling with limited clearance and multiple electrical conduits.
Our technicians:
-
Reinforced the ceiling support structure to ensure proper airflow without obstruction.
-
Installed a condensate lift pump to efficiently drain water where gravity drainage wasn’t possible.
-
Completed refrigerant and electrical connections with future maintenance in mind.
-
Tested all system modes to ensure full compliance with regulations and total customer satisfaction.
The result: steady temperature control, whisper-quiet operation during meetings, and fully preserved room aesthetics.
What to know before installation
Heat load evaluation
Before any installation, our team performs a comprehensive thermal analysis of the space. This ensures the correct BTU sizing, avoiding performance issues or energy waste.
Ceiling configuration
A ceiling cassette requires enough space between the drop ceiling and the structural slab above. At least 30 to 35 cm of clearance is needed to properly house the unit.
Regular maintenance
Like all HVAC equipment, ceiling cassettes need annual maintenance, including:
-
Filter cleaning
-
Condensate line inspection
-
Refrigerant line checks
-
Thermostat calibration
At AirGreen, we offer custom preventive maintenance contracts to extend your system’s lifespan.
Available grants and rebates
Installing a ceiling cassette within an energy-efficient heat pump system may qualify you for government grants, including:
-
The Hydro-Québec LogisVert Program (up to $5,000 depending on eligibility)
-
The federal Canada Greener Homes Grant (via Transition énergétique Québec)
-
