A discreet and high-performance solution for uniform comfort in Montreal and its surroundings

At AirGreen, we regularly install ceiling cassette heat pump systems in modern residences, condos, and commercial spaces in Montreal, Laval, Longueuil, on the North Shore, and the South Shore. The FORESTAIR E24 9,000 BTU model stands out as a particularly attractive solution when aesthetics, air distribution, and energy efficiency are priorities.

Unlike traditional wall-mounted units, this cassette integrates directly into the ceiling, offering 360° uniform air diffusion and a virtually invisible design. This type of installation is highly sought after in high-end renovation projects or new constructions where every detail matters.


Why choose a FORESTAIR E24 ceiling cassette?

Superior air distribution and homogeneous comfort

One of the main advantages of this FORESTAIR cassette heat pump is its ability to distribute air uniformly throughout the room. Thanks to its multiple swing angles, it helps avoid hot or cold spots.

In several projects carried out by AirGreen in Boucherville and Laval, we observed a significant improvement in comfort compared to wall-mounted systems, especially in open spaces like living rooms combined with kitchens.

Performance adapted to the Quebec climate

This unit is designed to operate efficiently even in harsh winter conditions:

  • Heating capacity down to -25°C
  • Stable performance even at -15°C with 7400 BTU
  • High COP at low temperatures

This makes it a perfect solution for the climate of Montreal and Montérégie, where winters require reliable systems.

R-454B refrigerant gas: a modern and responsible choice

The FORESTAIR E24 model uses R-454B refrigerant, a significant evolution in the HVAC industry. This gas features:

  • A reduced global warming potential
  • Improved energy efficiency
  • Compliance with new environmental standards

At AirGreen, we are increasingly recommending systems using this type of refrigerant, especially for residential projects in Longueuil and on the South Shore, where clients are looking for sustainable solutions.


Installation by AirGreen: what you need to know

Real case: installation in a condo in Laval

Recently, our team installed a FORESTAIR E24 cassette in a condo in Laval. The client wanted to replace a wall-mounted unit that was deemed too visible and poorly positioned.

Challenges encountered:

  • Restricted ceiling space
  • Complex drainage due to existing configuration
  • Need to maintain a high-end aesthetic

AirGreen solution:

  • Installation of an integrated drain pump
  • Precise adjustment of the ceiling structure
  • Airflow calibration to avoid cold spots

Result:

  • Significantly improved comfort
  • Reduced sound level
  • Completely sleek aesthetic

Common mistakes to avoid with ceiling cassettes

Improper sizing

A 9,000 BTU system is ideal for certain specific areas. Installing an undersized or oversized unit can lead to:

  • Energy inefficiency
  • Premature wear
  • Thermal discomfort

At AirGreen, we always perform a precise analysis before each installation in Montreal, Laval, and Longueuil.

Poor drainage management

Cassettes require a reliable drainage system. Improper installation can cause:

  • Water leaks
  • Ceiling damage
  • Humidity problems

That's why we systematically use systems with integrated protection, like that of the FORESTAIR E24.

Inadequate positioning

A poorly positioned cassette can create unpleasant drafts. Field experience is essential to optimize distribution.


Maintenance and durability

Maintenance of this unit is relatively simple, but essential:

  • Regular filter cleaning
  • Drainage check
  • Annual inspection by an HVAC professional

Thanks to its easy-to-clean filter, this unit is particularly popular in residential environments where maintenance must remain accessible.

  • Modern condos
  • Homes with suspended ceilings
  • Professional offices
  • Open commercial spaces
  • High-end renovation projects

It is less suitable for low ceilings or installations where technical access is limited.
