Installation of a GREE FREE MATCH R32 DoubleZone heat pump in Vaudreuil-Dorion: two zones, two wall units, and an HVAC installation designed for a real space
AirGreen installs a GREE FREE MATCH R32 DoubleZone heat pump in Vaudreuil-Dorion: two zones, two wall units, clean finish, and lasting HVAC comfort.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
A DoubleZone GREE installation in Vaudreuil-Dorion where every detail mattered
In Vaudreuil-Dorion, this installation of a DoubleZone GREE FREE MATCH R32 heat pump perfectly illustrates the type of project where equipment choice alone is not enough to guarantee a good result. In a house or condo, the performance of an HVAC system depends as much on the quality of the machine as on the precision of the installation, the positioning of indoor units, the routing of piping, respecting clearances, and the team's ability to adapt to the building's real constraints.
In this particular case, the client wanted a two-zone solution with 2 wall-mounted heads, capable of offering more uniform comfort without multiplying outdoor units. The chosen system, the GREE FREE MATCH R32, allows multiple indoor units to be connected to a single outdoor unit, making it a very interesting option for residences where exterior aesthetics, available space, and energy efficiency are priorities.
In the installation photo, you can see one of the wall-mounted heads installed high up, above a long line of lighting. This setup required special attention: the unit had to be high enough to ensure good air distribution, but also perfectly positioned so as not to interfere with the lighting, ceiling, side walls, and existing architectural elements. This is exactly the kind of detail that distinguishes a simple installation from a true professional HVAC installation.
At AirGreen, we know that projects in Montreal, Laval, Longueuil, on the North Shore and on the South Shore are never the same. Even when installing the same model, each building imposes its own constraints: available height, wall structure, drain routing, electrical panel location, refrigerant line distances, access to the outdoor unit, owner or condominium association requirements. This installation in Vaudreuil-Dorion is a perfect example.
Why choose a GREE FREE MATCH R32 for a two-zone installation?
The GREE FREE MATCH R32 is a multi-zone solution designed to offer flexibility. Unlike a single-zone system, which serves only one room or one open area, a DoubleZone heat pump allows air conditioning and heating of two distinct spaces with a single outdoor unit.
This configuration is particularly useful when two zones of the house have different needs. For example:
- an open living room and a master bedroom;
- a basement and a ground floor;
- a home office and a living area;
- two rooms located on different facades;
- a home where the outdoor space does not allow the installation of multiple condensers.
In the case of this installation in Vaudreuil-Dorion, the goal was to create stable comfort in two distinct zones while maintaining a clean, discreet, and durable installation. The choice of R32 refrigerant is also an important element. R32 is used in several modern systems because it allows good energy efficiency while reducing environmental impact compared to some older refrigerants.
The FREE MATCH series from GREE is appreciated for its modularity: it allows adapting the combination of indoor units according to the actual needs of the building. For a client, this means it is possible to choose a wall unit suited to each zone, rather than imposing a uniform power everywhere. This flexibility is essential to avoid two common mistakes: oversizing a smaller room or undersizing a zone more exposed to the sun.
A wall unit installed above the lighting: precision, alignment, and clearances
One of the most interesting elements of this installation is the visible location of the indoor unit. The wall unit is installed on a smooth wall, above a long light strip. At first glance, the installation seems simple, but this type of location requires a lot of precision.
A heat pump wall unit must meet several criteria:
- It must allow good air circulation.
- It must remain accessible for HVAC maintenance.
- It must not blow directly onto an immediate obstacle.
- It must be properly leveled to ensure adequate drainage.
- It must be installed in a place where piping and the drain can be routed neatly.
- It must visually integrate into the room without creating clutter.
In this installation, the AirGreen team had to work with a wall height limited by the ceiling, a fixed lighting line, and close side walls. The unit had to be centered and carefully installed to maintain a clean appearance. A misaligned installation would have been immediately noticeable, especially with the linear lighting just below. The interplay of shadow and continuous light makes small flaws much more apparent.
Our technicians therefore took the time to check measurements, level, clearances, and access to the unit’s service panel. This step is essential because a wall unit installed too close to the ceiling or a side wall can lose efficiency and become harder to maintain. Conversely, a unit installed too low would have harmed the room’s aesthetics and air distribution.
The key role of positioning in a DoubleZone installation
In a 2-zone system, the positioning of wall units has a direct impact on final comfort. Poor placement can cause cold spots, overly warm areas, short cycles, or a feeling of discomfort despite the machine’s proper capacity.
For this project in Vaudreuil-Dorion, the AirGreen approach involved analyzing not only where the unit could be installed but also where it should be installed to function properly. The difference is significant.
A wall unit should not just be installed where the wall is available. It must be placed based on:
- the shape of the room;
- the ceiling height;
- internal heat sources;
- the building's orientation;
- the doors and openings;
- the occupants' lifestyle habits;
- the most logical route for the refrigerant lines;
- the possible location of the outdoor unit.
In Greater Montreal, we often encounter buildings where clients think there is only one possible spot for a wall unit. After analysis, it is sometimes possible to find a better position—less visible, more efficient, or easier to maintain. This kind of thinking allows for a durable and pleasant daily installation.
GREE FREE MATCH R32: comfort, modulation, and energy efficiency
The GREE FREE MATCH R32 uses technology designed to adapt the system's operation to the actual needs of the served zones. Rather than operating only in on-off mode like some older systems, a modern heat pump can modulate its capacity to maintain a more stable temperature.
This modulation is particularly interesting in a DoubleZone installation, as the two rooms do not always require the same amount of heating or cooling at the same time. A bedroom may need less air conditioning than a sun-exposed living room, while a closed office can warm up faster with electronic equipment and occupancy.
The multi-zone system thus improves comfort while limiting external clutter. For many owners in Vaudreuil-Dorion, Montreal, Laval, Longueuil, on the North Shore and the South Shore, this feature is a major advantage. A single outdoor unit can serve two zones, simplifying installation and reducing the visual impact outside the property.
Eligibility for subsidies, when applicable, depends on the exact combination of installed equipment, AHRI numbers, capacity, energy efficiency, and criteria in effect at the time of the project. At AirGreen, we always verify the relevant information to help our clients understand the available programs and prepare the necessary documents after installation.
A clean installation in a demanding technical space
The image shows an indoor environment where the installation had to remain clean and controlled. Light walls, intense lighting, and proximity to surfaces make the finishes very visible. In this type of room, a poorly placed duct, an approximate hole, or a slightly tilted unit can harm the overall appearance.
Our technicians therefore paid special attention to several elements:
Wall preparation
Before installation, it is necessary to ensure that the wall can support the indoor unit stably. The wall plate must be securely fixed and perfectly level. This step directly affects the stability of the wall head and the quality of the drainage.
Drain management
A wall system produces condensation in cooling mode. The drain must be installed with an adequate slope to avoid water backflow, drainage noises, or humidity problems. In installations where space is limited, this part often requires more planning than expected.
Routing of refrigerant lines
The piping must be protected, well insulated, and installed according to best practices. Poorly bent, poorly insulated, or poorly routed pipes can create efficiency losses and complicate future interventions. A professional HVAC installation considers immediate performance but also long-term maintenance.
Visual finish
In a well-lit room, the finish is important. A successful installation should look natural, as if the unit had been planned from the start in the room's design. This is especially true for wall heads installed above a fixed element like a light strip.
Common mistakes to avoid with a DoubleZone heat pump
When a customer shops for a DoubleZone heat pump, it can be tempting to compare only price or brand. However, several mistakes can be costly in the long run.
Choosing capacity without room analysis
Two rooms of similar size can have completely different needs. Sun exposure, insulation, ceiling height, number of windows, and room use change everything. A good assessment allows choosing the right combination of heads.
Installing heads based only on aesthetics
Aesthetics are important, but they should not compromise air distribution. A wall head installed in a too closed corner or too close to an obstacle can reduce comfort and force the system to work harder.
Neglecting access for maintenance
Filters must be accessible. The unit must be able to be opened and cleaned. A head installed too close to the ceiling or in a tight space can make HVAC maintenance more difficult.
Forgetting the reality of drainage
Drainage is often one of the most underestimated aspects. Even a quality machine can cause problems if condensation is not properly drained.
Comparing quotes without comparing installation quality
Two quotes may mention the same model but include very different installation standards. The quality of the exterior support, insulation, pipe routing, pressure tests, vacuum, commissioning, and finishes can vary greatly.
The final result: an efficient, discreet, and adapted 2-zone solution for Vaudreuil-Dorion
At the end of this installation, the client benefits from a GREE FREE MATCH R32 system capable of serving two zones with a single outdoor unit. The wall unit visible in the photo fits neatly into the space, despite the presence of linear lighting and a demanding wall configuration. The installation was carried out with particular attention to alignment, clearances, drainage, and finishing.
This type of project clearly shows why the experience of an HVAC contractor is essential. The machine is important, but it is the installation that allows you to get the best performance. A heat pump that is well chosen, well positioned, and properly commissioned offers more stable comfort, better efficiency, and a more pleasant daily use.

Practical advice for homeowners considering a DoubleZone installation
Before choosing a 2-zone system, it is useful to consider a few concrete points:
- Which rooms really need heating and air conditioning?
- Are both zones used at the same time?
- Is one of the rooms more exposed to the sun?
- Are there significant aesthetic constraints?
- Where can the outdoor unit be installed without disturbing the neighbors?
- Can the ductwork be installed neatly?
- Will filter maintenance be easy?
- Is the chosen combination eligible for a subsidy?
These questions help avoid unpleasant surprises. A good HVAC installation always starts with a thorough analysis. The best system is not necessarily the biggest or the most expensive, but the one that precisely matches the building and the client’s needs.
