Installation of a Gree FreeMatch MultiZone heat pump in Fabreville (Laval): customized comfort, summer and winter
In Fabreville, AirGreen installed a Gree FreeMatch MultiZone heat pump on wall brackets, with optimal clearance and secure power supply, for room-by-room comfort adapted to the winters of Greater Montreal.
In summer, the outdoor unit rejects the house's heat outside.

Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
In Fabreville, Laval, single-family and semi-detached homes often share a common characteristic: different comfort needs from one floor to the next, and rooms that react differently depending on sunlight, insulation, or occupancy. In this type of configuration, a MultiZone heat pump quickly becomes the most logical solution—and that's precisely why we installed a Gree FreeMatch here, a system designed to power several indoor units from a single outdoor unit.
The photo clearly shows the outdoor unit installed against vinyl siding, on the foundation, with careful attention paid to clearance and accessibility. This is a typical "clean and efficient" installation that we at AirGreen favor: durable, easy to maintain, and adapted to the weather conditions of Greater Montreal.
Why a Gree FreeMatch in this area of Laval?
The MultiZone addresses a very common need in Fabreville:
-
An upstairs bedroom that overheats in the summer
-
A ground floor that stays cooler in winter
-
A basement that needs to be kept at a comfortable temperature without overheating the rest of the house
The Gree FreeMatch (multi-zone range) allows you to zone the temperature: each zone has its own control, while sharing a single outdoor compressor. The result: more comfort, fewer compromises.
Model (consistent with the observed installation)
Without a clearly visible license plate in close-up, we are left with a cautious, but consistent, identification:
-
Gree FreeMatch Multi R-32 , 2 to 3 zone configuration (common residential format)
-
Typical capacity for this size: approximately 30,000 to 42,000 BTU depending on the number of zones and indoor units chosen.
In real life, it is primarily the correct sizing (and the correct distribution of zones) that makes the performance — not an overbidding of BTUs.
Visible installation details: what we did (and why it's important)
Even an excellent machine can become noisy, less efficient, or more difficult to maintain if the installation isn't done properly. Several elements in this installation speak volumes:
1) Installation on wall brackets above the floor
The outdoor unit is mounted on wall brackets fixed to the structure/foundation, which:
-
limits snow accumulation around the unit in winter
-
reduces the risk of standing water in spring
-
improves airflow (crucial for efficiency)
-
facilitates maintenance (cleaning, inspection, defrosting)
2) Clearance and air circulation
We see a clear area in front of the fan: this is essential to avoid:
-
cold air recirculation in heating mode
-
reduced yield during periods of extreme cold
-
more frequent cycles (therefore more wear and tear)
3) Power supply and safety
The disconnect/circuit breaker box is installed nearby, which is good practice:
-
Rapid intervention in maintenance
-
Compliance and safety for technicians
-
cleaner and more reliable long-term installation
4) Management of connections (piping/insulation)
Refrigerant piping runs are distinguished: in a MultiZone system, the quality of the installation is crucial, as several internal circuits depend on proper balancing and clean execution (bending radii, insulation, sealing, etc.). Careful installation = less loss, less vibration, and better longevity.
The real advantage of a MultiZone system: "room-by-room" comfort
In a house in Laval, comfort is never uniform. A Gree FreeMatch MultiZone allows, among other things:
-
A cold room in winter : it's given its own zone, without overheating the living room.
-
A home office : stable temperature all day
-
A room with extensive glazing : rapid compensation for solar gains
-
Different habits : everyone adjusts their own zone (without any fuss about the thermostat).
And what about energy? A well-designed system avoids unnecessarily heating/cooling spaces that don't need it.
Heating performance: what we're aiming for in Quebec
In Greater Montreal, a heat pump must be designed to:
-
freezes/thaws
-
humidity
-
blown snow
-
the more pronounced cold spells
A well-installed and well-sized MultiZone maintains excellent comfort for most of the season, with a simple logic: good height, good clearance, good installation of connections, and an intelligent zone configuration .
Common mistakes that we systematically avoid at AirGreen
In practice, here are the things that cause the most problems (and that are corrected from the design stage):
-
Unit too low : buried in snow, reduced efficiency, complicated defrosting
-
Lack of clearance : noise, air recirculation, reduced performance
-
Poorly insulated connections : losses, condensation, premature wear
-
Sizing "by feel" : short cycles, discomfort, higher bill
-
Poorly designed zoning : one zone "steals" capacity, the other lacks power
Our approach: we install so that it works now , and still works in 10 years .
Why entrust a Gree FreeMatch installation to AirGreen in Laval?
Because MultiZone requires more than a "standard" installation. It requires:
-
a solid zoning logic
-
meticulous installation of the connections and exterior placement
-
clean and durable execution (supports, vibrations, access, safety)
-
an aesthetic and practical result (especially in residential settings)
In Fabreville, as elsewhere on the island and the north/south ring, the aim is always the same: reliable, discreet comfort, optimized for our winters .
Conclusion: a clean, scalable, and perfectly adapted installation
This Gree FreeMatch MultiZone heat pump installation in Fabreville (Laval) perfectly illustrates what we love to deliver: a well-positioned, well-supported, safe system, ready to provide precise comfort to multiple zones of the home. When the MultiZone is well-designed, you “feel” it every day… but you forget it's even there in your routine, because everything works so simply.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
