When we think of residential comfort, we often picture the living room or bedrooms… but in reality, it's often the "secondary" rooms that present the most challenges: a finished basement, a playroom, a home office, a workshop, or a storage room that also serves as living space. In Fabreville (Laval), our AirGreen team installed a Gree FreeMatch multi-zone wall-mounted heat pump specifically to stabilize the temperature of a lower-level space and improve daily comfort—summer and winter.
The photo clearly shows the wall-mounted indoor unit installed high up, near the ceiling, with a typical approach to careful installation: adequate clearance, logical positioning for air distribution, and work in progress using a stepladder and protective measures. This type of setup is very common in Laval houses and cottages, where basements play a central role in family life.
Why a Gree FreeMatch in a basement in Laval?
A basement, even a well-finished one, does not have the same thermal behavior as a main floor:
-
humidity tends to be more prevalent (especially in summer);
-
the air is more "dense" and natural circulation is less efficient;
-
Temperature variations can be marked between day and night;
-
Some rooms remain too cool in winter, too heavy in summer.
The Gree FreeMatch is particularly interesting in these contexts because it is part of an evolving logic: you can start with one zone (like here, a wall unit) and, depending on the configuration of the building, plan the addition of other zones (e.g. bedroom upstairs, office, conservatory), while remaining in a clean and compact approach.
Type of system installed
In this project in Fabreville, it involves:
Multi-Zone Heat Pump (mini-split multi-zone) – Gree FreeMatch
with indoor wall head (indoor unit) installed in a basement room.
Model (consistent with the range)
The image does not allow for the reading of a precise nameplate. We therefore present the equipment realistically and faithfully to the product range:
-
Gree FreeMatch – residential multi-zone system (new generation)
-
Typical configuration: 1 to 2 zones (expandable depending on the house)
-
A capacity often chosen for this type of space is approximately 12,000 BTU (sized according to area, insulation and use).
At AirGreen, the final capacity is never chosen "at random": it is determined according to the air volumes, the level of insulation, the orientation, the actual use of the room and the way the house is currently heated.
Observable installation details and key technical points
Even if a photo doesn't show everything (outdoor unit, drilling, drainage, wiring), it reveals several important elements about how the installation was designed.
1) Positioning the wall unit
The unit is installed high on the wall , which is ideal for:
-
promote even air distribution;
-
avoid direct airflow at the level of the sofa or seating areas;
-
maintain good clearance under the device;
-
Optimize air mixing, particularly useful in a basement.
2) Indoor environmental management
We see a real living space: furniture, shelves, objects, circulation. In this type of room, our technicians primarily work on:
-
surface protection (floors, furniture, walls);
-
dust reduction during drilling;
-
the cleanliness at the end of the construction site (a detail that makes all the difference for the client).
3) Connection and finishing
On a clean wall-mounted installation, the refrigerant lines , communication cable, and condensate drain must be:
-
routed with a logical slope for drainage;
-
protected and securely fixed;
-
aesthetics (well-aligned gutters, discreet outlets).
In a basement with a lower ceiling, every centimeter counts: the layout must be designed to avoid obstacles, maintain a good appearance, and facilitate future maintenance.
4) Condensate drainage (a common issue in basements)
In air conditioning mode, a wall-mounted heat pump produces condensation. In the basement, the drainage strategy must be impeccable:
-
sufficient slope;
-
path without a counter-slope;
-
output or logic connection (depending on configuration).
This is a point we treat with great rigor, because a poorly designed drain can lead to problems with water, odors or persistent dampness.
5) Commissioning
A quality installation isn't just about "hanging a wall-mounted unit." Commissioning includes, among other things:
-
compliant vacuuming;
-
leak test;
-
verification of operating parameters;
-
validation of modes (heating, air conditioning, dehumidification);
-
simple usage instructions for the customer.
Winter comfort in Quebec: what FreeMatch actually delivers
In Laval, people want a system that doesn't panic as soon as the temperature drops. A well-chosen and properly installed heat pump offers:
-
stable heat for cooler rooms (such as basements);
-
a better overall balance of the home;
-
a reduction of the "cold floor" effect thanks to better controlled air temperature;
-
efficient air conditioning in summer, without excessive noise.
And above all: comfort becomes predictable . We no longer have to "compensate" by opening/closing doors, adding extra heaters, or living with an uncomfortable room half the year.
Why AirGreen for a Gree installation in Laval?
In areas like Fabreville, Sainte-Dorothée, Chomedey, and Duvernay, homes often share similar characteristics: finished basements, multi-purpose rooms, renovations over time, and finishing constraints. Our added value lies in providing a professional installation.
-
correctly sized (avoid oversizing and short cycles);
-
clean and aesthetic (because it's a living space, not a mechanical room);
-
designed for durability (drainage, fixing, access for maintenance);
-
adapted to the climate (consistent operation in heating and cooling).
We also take the time to explain the use: modes, realistic instructions, good practices to maintain high performance (cleaning the filters, clearance, seasonal adjustments).
Some simple tips to maximize performance and longevity
After installation, here's what actually helps:
-
Clean the filters regularly (especially if the space is used as a playroom or workshop).
-
Keep some clearance around the wall unit (avoid furniture too close).
-
In winter, aim for a stable setpoint rather than constantly going up/down.
-
In summer, use the dehumidification mode when the humidity in the basement is high.
Conclusion: a logical, clean, and scalable solution
This installation in Fabreville (Laval) perfectly illustrates a common scenario: a home where basement comfort makes all the difference. With a Gree FreeMatch multi-zone heat pump , you get an efficient, quiet, and adaptable solution—while tangibly improving quality of life, season after season.
At AirGreen, our approach is simple: a clean installation, solid technical logic, and a result that is immediately noticeable.
