A discreet and high-performance ducted solution for residential comfort in Quebec

At AirGreen, we regularly install ducted HVAC systems for clients who desire uniform comfort without compromising their interior aesthetics. The FORESTAIR E24 18,000 BTU ducted heat pump stands out as a particularly suitable solution for properties located in Montreal, Laval, Longueuil, on the North Shore, and the South Shore, especially in high-end renovation projects or new constructions.

Unlike visible wall-mounted units, this system integrates directly into ceilings or false ceilings, distributing air through a network of ducts. The result: homogeneous, silent, and invisible air conditioning and heating.


Why choose a FORESTAIR E24 ducted heat pump?

An ultra-compact design for confined spaces

One of the most remarkable features of this model is its ultra-slim profile of only 7.88 inches in height, allowing for installation in confined spaces, such as suspended ceilings or attics.

At AirGreen, we recently installed this model in a duplex in Rosemont (Montreal) where ceiling height limited options. This unit integrated perfectly without requiring major structural modifications.

Silent operation ideal for living spaces

The indoor sound level ranges between 36 and 41 dB(A), which is comparable to a soft whisper.
This makes it an excellent choice for:

  • Bedrooms
  • Home offices
  • High-end condos
  • Discreet commercial spaces

A client in Boucherville (South Shore) specifically requested a quiet solution for their home office — this heat pump exceeded their expectations.


Performance adapted to Quebec's climate

Efficient heating down to -25°C

The FORESTAIR E24 is designed to operate efficiently even during harsh Quebec winters, with a heating capacity down to -25°C. This means:

  • Less reliance on auxiliary systems
  • Constant comfort even in very cold weather
  • Reduced energy costs

Certified energy efficiency

This heat pump is:

  • ENERGY STAR®
  • ENERGY STAR® Cold Climate Certified
  • Equipped with a high SEER2 and a high-performing HSPF2

These features allow homeowners to benefit from excellent energy efficiency, thereby reducing their electricity bills in the long term.


Key technical data to know

Here are the important specifications we systematically analyze at AirGreen before any installation:

Capacities and performance

  • Nominal power: 18,000 BTU
  • Capacity at -8°C: 14,500 BTU
  • Capacity at -15°C: 13,200 BTU
  • COP at -8°C: 11.83

Airflow and static pressure

  • Airflow: up to 900 m³/h (529 CFM)
  • Static pressure: up to 100 Pa

This pressure allows for efficient air distribution in multiple rooms via ducts, even in complex configurations.

Dimensions and installation

  • Interior dimensions: 36.22 x 7.88 x 19.30 inches
  • Piping: 1/4 – 1/2 in
  • Voltage: 220V

These characteristics make this unit compatible with the majority of standard residential installations in the Montreal area.


Real-world experience: installation in Laval in an intergenerational home

We recently completed a full installation in an intergenerational home in Laval. The main challenge was to:

  • Maintain a stable temperature on two floors
  • Avoid visible wall units
  • Reduce noise pollution

We opted for the ducted FORESTAIR E24, with an optimized duct network.

Result:

  • Uniform temperature in all rooms
  • No visible units
  • Significant noise reduction compared to their old system

The client also benefited from the LogisVert grant of $1,720, which made the project even more cost-effective.


HVAC installation: common mistakes to avoid

Even with excellent equipment, poor installation can compromise performance. Here are the mistakes we often observe (and systematically avoid at AirGreen):

Incorrect duct sizing

Improperly calculated airflow leads to:

  • Cold or hot spots
  • Excessive energy consumption
  • Premature system wear

Poor drainage management

This unit includes a built-in 47-inch condensate pump, facilitating condensate removal.
However, improper installation can cause:

  • Water leaks
  • Mold
  • Structural damage

Inadequate air intake positioning

Thanks to its flexible air return, this unit allows for several configurations.
But poor design can reduce the overall efficiency of the system.
