In several homes in Fabreville, Laval , a very typical situation prevails: a garage used as a utility space, sometimes low ceilings under the stairs, and an existing network of ducts that residents are determined to keep. It is precisely in this context that our AirGreen team stepped in to install a Gree central heat pump , with an air manager (indoor unit) installed horizontally to optimize space without compromising performance.
Our goal: to offer reliable heating in winter and stable air conditioning in summer , while keeping the installation clean, accessible for maintenance, and perfectly adapted to the residential reality of Greater Montreal.
Why a Gree central heat pump in Fabreville
In Laval, and particularly in areas like Fabreville where there are many single-family homes, a central heat pump remains one of the most logical solutions when:
-
Ventilation ducts (central air distribution) already exist.
-
We want a consistent level of comfort from one floor to the next.
-
We are looking for an "all-in-one" solution (heating + air conditioning).
-
We want a sustainable installation, designed for Quebec's temperature cycles.
The Gree brand fits very well into this type of project: it offers robust central systems, designed to work efficiently in real-world conditions, with a performance and stability- oriented approach.
In this project, the choice fell on a Gree Flexx R32 (a coherent range for a central residential installation), a model appreciated for its versatility and its integration into existing configurations.
The context of the project: installation in a garage, under space constraints
The photo perfectly illustrates a situation that is often encountered: a central indoor unit installed in a garage , under a structure (here, a low ceiling / under stairs), with access points to be preserved for maintenance.
In this type of environment, our job isn't just about "setting up a machine." It also involves:
-
choose the position (horizontal vs vertical),
-
manage condensation drainage,
-
secure and insulate pipe penetrations,
-
ensure that everything remains accessible (signs, filters, service),
-
limit vibrations and noise transmitted to the structure.
The visible installation details and what they mean
Several elements immediately stand out in this installation (and it is precisely these details that make a difference in long-term reliability):
1) Gree indoor unit installed in a horizontal configuration
The air manager is mounted high up , freeing up floor space. This approach is ideal in a garage, especially when you want to maintain a storage or circulation area.
2) Condensate management with trap (siphon)
We see a well-structured drainage system (with a siphon). This is essential for:
-
to prevent unwanted air from flowing back into the drain,
-
to ensure a stable flow,
-
prevent odors and moisture problems around the unit.
3) Insulated refrigeration connections
The pipes are insulated (black sheath), which is crucial for:
-
reduce condensation on the lines,
-
limit energy losses,
-
to stabilize the system's performance in both heating and air conditioning.
4) Sealed wall penetration
The pipes are neatly routed to the outside and sealed (a foam insulating finish is visible). This is an often overlooked point, but it has an impact on:
-
cold air leaks,
-
humidity,
-
the durability of the building envelope.
5) Retained service access
Even in a confined space, the installation maintains a logical flow: accessible panels, organized lines, visible components. At AirGreen, we always prioritize an installation that remains maintainable —because a central system requires ongoing maintenance.
What this central heat pump changes on a daily basis
A properly installed central heat pump in Fabreville is not just an “equipment replacement.” It’s a transformation of comfort:
-
More uniform temperature between the basement, ground floor and upper floor.
-
Less variation during large temperature differences.
-
More stable air conditioning during the July heatwaves.
-
A feeling of “constant” comfort, without hot/cold zones.
And most importantly: when the installation is done correctly (drain, insulation, access, fixing), you avoid the classic problems that cost a lot in the long run.
The points we systematically check on a Gree control unit
Every house is different, but our methodology remains the same. For a system like the Gree Flexx R32 , we specifically validate:
-
Airflow and statics : the ductwork network must be able to “breathe”.
-
Sealing of fittings and plenums.
-
Drainage : slope, siphon, safety (depending on the context).
-
Isolation of critical sections.
-
Fixing / anti-vibration : to prevent noise transmitted to the structure.
-
Calibration and commissioning : pressures, temperatures, behavior in heating mode.
It is this discipline that allows us to have a system that truly performs — not just on the day of installation, but for years to come.
Why Fabreville (Laval) is an area where the power plant makes sense
Fabreville often combines:
-
houses of varying sizes,
-
gradual renovations (windows, insulation, etc.),
-
existing systems (electric furnace, central ventilation),
-
significant heating needs in winter.
In this context, a Gree central heat pump becomes a smart choice: existing infrastructure (ducts) is maximized, efficiency is improved, and overall home comfort is increased.
Our AirGreen approach: clean, logical, sustainable
This project perfectly encapsulates our way of working:
-
We think “system” (not just “machine”).
-
We install it so that it is beautiful , but above all , functional .
-
We are keeping future maintenance in mind: filters, access, drainage.
-
We adapt the solution to the building — not the other way around.
If you are in Laval (Fabreville, Sainte-Dorothée, Chomedey, Vimont, Duvernay) or elsewhere in Greater Montreal, and you are considering a central heat pump, our team can guide you towards a configuration that is truly adapted to your home and your objectives (comfort, budget, efficiency, longevity).
