Commercial air conditioning in Montréal is a strategic concern for businesses aiming to ensure optimal comfort for both their clients and employees, while also meeting increasingly strict energy efficiency standards. In this context, the ceiling cassette indoor unit stands out as an essential solution. At AirGreen, we’ve supported hundreds of businesses, offices, and professional establishments throughout Montréal, Laval, Longueuil, the North Shore and the South Shore with the installation of this high-performance, discreet equipment, perfectly suited for modern commercial environments.
A system designed for professional spaces
The cassette unit is known for its ability to distribute air evenly in four directions, thanks to its strategic ceiling placement. Unlike wall-mounted or console units, it integrates seamlessly into drop ceilings, freeing up wall and floor space — a valuable asset for shops, open-plan offices, clinics, or restaurants.
Aesthetic, efficient, and space-saving
We understand that every square foot matters for professionals. That’s why we recommend ceiling cassette units whenever wall or floor space is limited, or when a clean, uncluttered design is desired. Their discreet integration helps preserve the interior aesthetics while ensuring fast and effective cooling throughout the space.
360° air diffusion for consistent comfort
Unlike standard air conditioners, ceiling cassettes distribute air simultaneously in multiple directions, providing even temperature coverage — even in large spaces. This feature is particularly valuable in commercial areas with high ceilings, where maintaining consistent comfort zones can be challenging.
Case Study: Installation of a Commercial Daikin Cassette in Outremont
A recent project led by AirGreen in Outremont perfectly illustrates the advantages of this system. A 120 m² dental clinic was looking to upgrade its outdated air conditioning setup, which relied on two inefficient wall units. We chose a Daikin 36,000 BTU ceiling cassette with an Inverter compressor and R-32 refrigerant, an environmentally friendly low-impact solution.
Challenges encountered:
-
Fragile plaster drop ceiling, requiring precise cutting.
-
Limited space for refrigerant lines and condensate drain.
-
Need to maintain clinic operations during installation.
AirGreen solutions:
-
Work carried out in two phases, outside patient hours.
-
Use of flexible ducting to minimize impact on existing structure.
-
Installation of a silent lift pump for condensate drainage.
Result: uniform temperature across the clinic, notably reduced noise levels, and a visually cleaner space. The client praised our team’s professionalism and the high-quality system integration.
Energy efficiency and available grants
Recent models of ceiling cassettes like Daikin, Fujitsu, Gree, or Mitsubishi Electric offer high energy performance ratings (SEER/SCOP), making them eligible for Hydro-Québec’s LogisVert grants. At AirGreen, we assist our clients with every step of the application process for these incentives, which can reach up to $1,860 for certain reversible heat pump systems.

Frequently asked questions from our commercial clients
Can a cassette unit be installed in a concrete ceiling?
Yes, with specialized support kits or by adding a drop ceiling — often more affordable than people think.
Is the cassette noisier than a wall unit?
Not at all — quite the opposite. Modern cassette units are extremely quiet, often under 35 dB, making them ideal for noise-sensitive environments like clinics or meeting rooms.
How long does the installation take?
A standard installation takes 1 to 2 business days, depending on building access and layout complexity.
Best practices and mistakes to avoid
-
Underestimating the required capacity: A precise evaluation by a professional is crucial.
-
Skipping annual maintenance: A clogged filter = reduced performance = higher bills.
-
Installing without proper planning: Poor positioning can create unpleasant cold air drafts.
