A Discreet and High-Performing Solution for Uniform Comfort in Montreal and its Surroundings

In the field of HVAC in Montreal, Laval, Longueuil, North Shore, and South Shore, some projects require a different approach than traditional wall-mounted systems. The FORESTAIR E24 12,000 BTU ceiling cassette heat pump precisely meets this need: offering uniform comfort, without aesthetic compromise, while maintaining energy efficiency suited to Quebec winters.

At AirGreen, we regularly install this type of equipment in modern condos, professional offices, and commercial spaces where discretion and performance are essential. This particular model has stood out in several of our recent installations.


Why choose a cassette heat pump over a classic wall-mounted unit?

Optimal 360° Air Distribution

Unlike a wall-mounted unit, the ceiling cassette distributes air in multiple directions. The result: homogeneous temperature distribution throughout the room.

During a recent installation in Boucherville (South Shore), a client complained of a constant cold spot with their old wall unit. After replacement with a FORESTAIR E24 cassette, the temperature became uniform, even in distant corners.

Discreet Architectural Integration

The cassette integrates directly into a suspended ceiling. Only the decorative grille is visible. This makes it a preferred choice for:

  • Professional offices
  • Restaurants and businesses
  • High-end finished basements
  • Modern condos in Montreal

Detailed Technical Specifications of the FORESTAIR E24

Performance adapted to the Quebec climate

  • Cooling Capacity: 12,000 BTU
  • Effective Heating down to -25°C
  • Power at -15°C: 9,000 BTU
  • Power at -8°C: 10,500 BTU
  • ENERGY STAR® Certification (including cold climate)

These data confirm that this model is perfectly suited to the winter conditions of Montreal and Laval, where temperatures can drop rapidly.

Energy Efficiency

  • SEER2: 21.03
  • HSPF2: 10.15
  • EER2: 11.72
  • COP at -8°C: 1.93

This concretely translates into:

  • A significant reduction in energy costs
  • Eligibility for LogisVert subsidies ($1260)

Eco-friendly Refrigerant R-454B

The system uses R-454B, a gas that is more environmentally friendly than previous generations. At AirGreen, we systematically recommend this type of technology for recent projects aiming for better environmental compliance.


Technical Data from the Manufacturer

  • Airflow: up to 630 m³/h (370 CFM)
  • Indoor Sound Level: 42 dB(A)
  • Indoor Unit Dimensions: 570 x 570 x 235 mm
  • Integrated Drain Pump (47 inches)
  • Operating Range: -25°C to 30°C in heating

These elements confirm that the unit is designed for a reliable, quiet, and durable installation, even in complex configurations.


Typical Installation Carried out by AirGreen

Real Case: Professional Office in Laval

A client located in Laval contacted us to air condition an office space with a suspended ceiling. The constraints were:

  • Uniform air distribution among several workstations
  • Minimal noise level

Proposed Solution

We installed the FORESTAIR E24 cassette with:

  • Complete integration into the ceiling
  • Concealed piping
  • Drainage with integrated pump
  • Centralized control

Result

  • Uniform thermal comfort
  • No perceptible noise in work areas
  • Immediate client satisfaction

HVAC Installation Details to Consider

Technical Requirements
