A discrete and powerful solution for uniform comfort throughout the space
In the field of HVAC in Montreal, Laval, Longueuil, North Shore, and South Shore, certain configurations require solutions that are both powerful and discrete. The FORESTAIR E24 | 18,000 BTU ceiling cassette heat pump precisely meets this need. At AirGreen, we have installed this type of equipment in several residential and commercial projects where aesthetics, air distribution, and winter performance are essential.
Unlike conventional wall-mounted units, this cassette integrates directly into the ceiling, allowing for 360° air distribution, ideal for open-plan spaces, offices, businesses, or finished basements.
Why choose a FORESTAIR E24 ceiling cassette?
Uniform air distribution and true comfort
One of the major advantages of this unit is its ability to distribute air evenly throughout the room. Thanks to its multiple ventilation angles, it eliminates cold or hot spots.
In a project carried out in Boucherville, a client had a large open space combining kitchen and living room. Before the installation, a wall-mounted heat pump created significant temperature differences. After the installation of the FORESTAIR E24 cassette, the temperature became uniform throughout the area, even at more than 7 meters away.
Discrete and aesthetic installation
This unit is recessed into the ceiling with a minimal visible panel (650 x 650 mm), which preserves the aesthetics of modern or commercial spaces.
In several projects in Montreal (Plateau and Griffintown), our clients sought an invisible solution without compromising performance. The ceiling cassette was the ideal answer.
Energy performance and efficiency in the Quebec climate
Reliable heating down to -25°C
The FORESTAIR E24 is ENERGY STAR® and ENERGY STAR® Cold Climate certified, meaning it is designed to perform efficiently even in Quebec's harsh winters.
- Heating capacity down to -25°C
- Power at -8°C: 14,500 BTU
- Power at -15°C: 13,200 BTU
- COP at -8°C: 11.83
In concrete terms, this means that even during cold snaps on the North Shore or in Laval, the unit continues to produce stable heat without excessive reliance on auxiliary heating.
Impressive energy efficiency
- SEER2: 120.53
- HSPF2: 18.515
- EER2: 111.020
These performances significantly reduce energy costs. Several AirGreen clients who replaced a traditional electric system have observed a consumption reduction of up to 30%.

AirGreen real case: installation in an office in Longueuil
A commercial client in Longueuil contacted us to replace an old noisy and inefficient central system.
Initial problems:
- Uneven air distribution
- High noise level
- Excessive energy consumption
Proposed solution:
Installation of a FORESTAIR E24 cassette heat pump
Result:
- Significant noise reduction (45 dB indoor)
- Uniform comfort in all work areas
- Measurable decrease in energy bills
This type of project perfectly illustrates why ceiling cassettes are increasingly in demand in the commercial sector in Montreal and the South Shore.
Installation: essential points to consider
Complexity and required expertise
Unlike a wall-mounted heat pump, the installation of a cassette requires:
- Ceiling access (suspended ceiling or structural modification)
- Drainage management (pump included)
- Strategic positioning for optimal diffusion
- Precise electrical and refrigeration connections
At AirGreen, our certified refrigeration technicians meticulously plan each installation to avoid common errors.
Common errors to avoid
We have often been called upon to correct poorly executed installations:
- Incorrect positioning of the cassette (poorly distributed air)
- Poorly configured drainage (risk of leakage)
- Undersized system
These errors can completely compromise the system's performance.
Subsidies and profitability
This unit is eligible for a LogisVert subsidy of $1,740 (updated November 2025).
This significantly reduces the initial cost and improves the return on investment, especially for homeowners in Montreal, Laval, and Longueuil.
