A neat indoor installation in a house with marked architectural character
In Sainte-Thérèse, on the North Shore, our AirGreen team completed the installation of a TripleZone GREE FREE MATCH R32 heat pump, a 3-zone system with 3 wall units designed to offer precise comfort in several rooms of the residence. The project photo highlights one of the indoor units installed under a large exposed wooden beam, between two door openings, in a space where positioning had to be carefully calculated.
This type of HVAC installation is never just a matter of hanging a wall unit in a free spot. In a house with white panel ceilings, exposed wooden beams, close interior passages, and limited wall surfaces, every centimeter counts. The goal was clear: to install an effective and discreet heat pump, while respecting the interior character of the house and ensuring good air distribution.
The choice of the GREE FREE MATCH R32 model allowed meeting several needs at once: air conditioning different zones, providing effective supplementary heating during intermediate seasons, limiting the number of outdoor units, and giving occupants independent control room by room. For a residence in Sainte-Thérèse, where temperature variations between rooms can be significant depending on sunlight, insulation, and interior layout, a TripleZone configuration was a very relevant solution.

A 3-zone system to better distribute comfort
The GREE FREE MATCH R32 is designed for multi-zone installations. In this project, three wall units were connected to a single outdoor unit, allowing the management of three distinct spaces from a centralized system. This approach offers a major advantage: instead of treating the entire house as one large zone, each room or area can receive the temperature that matches its actual use.
In a family home, needs often vary from one space to another. A bedroom may require a cooler temperature in the evening, an office may need more air conditioning during the day, while an open living room may demand more stable air distribution. With a TripleZone heat pump, it becomes possible to adjust comfort more precisely without unnecessarily straining the entire system.
This flexibility is especially appreciated in residences in Montreal, Laval, Longueuil, the North Shore, and the South Shore, where buildings have very different configurations: recent condos, semi-detached houses, renovated bungalows, properties with successive additions, or older homes with exposed beams like in this project in Sainte-Thérèse.
The main challenge: installing a wall-mounted unit under a wooden beam
The photo shows a GREE wall-mounted unit installed under a massive wooden beam. This detail is important because a beam can influence the air trajectory, limit the space available above the device, and complicate access to the wall for drilling and connections.
Our technicians had to consider several elements:
- the available space between the beam and the top of the indoor unit;
- the height of the unit relative to the doors on each side;
- the orientation of the air outlet to prevent air blockage;
- the passage of refrigerant lines through or behind the wall;
- condensate drainage;
- the visual integration of the device in a room with a warm style.
The indoor unit visible in the photo is still protected by a plastic film, indicating a final installation step or protection before the final handover to the client. At AirGreen, we pay special attention to this kind of detail, especially in homes where finished surfaces, moldings, beams, and ceilings require careful handling.
A chosen location to promote air distribution
The location of a wall-mounted head directly influences the perceived performance. Installing a unit too low, too close to an obstacle, or in a poorly ventilated corner can reduce system efficiency, even if the machine is properly sized. In this project, the head was placed in a strategic position: high enough to promote diffusion, but sufficiently clear to allow the flap to direct air toward the targeted area.
The two visible door openings around the unit indicate that this head probably serves a passage area or a central space in the house. In this type of configuration, air can move to adjacent rooms, which helps balance the temperature. However, relying solely on hallways to air condition an entire house should be avoided. This is precisely the benefit of a 3 zones, 3 heads system: each important sector receives its own indoor unit.
The advantages of refrigerant R32 in this type of project
The GREE FREE MATCH R32 model uses refrigerant R32, a new generation refrigerant increasingly present in modern residential installations. For homeowners, this choice fits a logic of efficiency, performance, and current design.
In a multizone installation, the system must modulate according to the demand of the different heads. GREE's Inverter technology allows adjusting the compressor operation based on actual needs, rather than just running on/off. This modulation contributes to more stable comfort, better-controlled consumption, and a reduction in sudden temperature variations.
For customers comparing several options of wall-mounted heat pump or wall air conditioner, this ability to modulate is an important criterion. A well-installed and well-configured machine can offer a much more pleasant experience than an oversized or poorly positioned system.
A multizone installation that requires real planning
A TripleZone heat pump requires rigorous technical coordination. Each indoor unit must be connected to the outdoor unit by its refrigerant lines, communication cables, and condensate drainage system. In a three-head project, poor planning can lead to lines that are too long, visible passages, drainage constraints, or efficiency losses.
Before installation, our team analyzes:
- the layout of the rooms;
- the walls available for wall-mounted heads;
- the possible location of the outdoor unit;
- the distances between each zone;
- the cleanest path for the conduits;
- aesthetic constraints;
- the actual heating and cooling needs.
In the case of this house in Sainte-Thérèse, the interior architecture required a very precise approach. The presence of exposed wooden beams demanded respecting the aesthetics of the place while ensuring a safe and efficient installation. The visible result in the image shows a centered unit, well aligned and integrated without visual overload.
Sizing: a key point for 3-head systems
Sizing a heat pump should never be based solely on a quick estimate of the area. For a TripleZone configuration, each zone must be evaluated separately. A bedroom, a living room, an open kitchen, or an office do not have the same needs.
Factors to analyze include:
- the area of each room;
- ceiling height;
- the level of insulation;
- the number and size of windows;
- sun orientation;
- the presence of floors;
- natural air circulation;
- the occupants' living habits.
The GREE FREE MATCH R32 series allows different combinations of indoor units according to project needs. In this installation, the three units were chosen to meet the actual load of the targeted zones, rather than applying a uniform capacity everywhere. This approach avoids two common problems: an under-cooled zone that remains uncomfortable and an oversized zone that reaches the setpoint too quickly without properly dehumidifying.
Grants and potential eligibility
Several installations of heat pumps may be eligible for financial aid programs depending on the models, certified performance, current criteria, and installed configuration. For multi-zone systems, eligibility must be carefully verified, as it often depends on the exact combinations of indoor and outdoor units.
At AirGreen, we provide customers with the necessary information after installation: detailed invoice, model references, and useful information for procedures. Since programs can change, we always recommend validating the applicable conditions at the time of the project. Our role is to install a compliant, documented, and clear system to facilitate what comes next.
Mistakes to avoid with a TripleZone heat pump
A multi-zone system can offer excellent comfort, but only if the installation is done correctly. Here are the most common mistakes we observe in the field.
Placing the heads according to available space rather than air distribution
It is not enough to find an empty wall. The head must be placed to distribute air effectively. In a house with beams, doors, and special ceilings, analyzing the air trajectory is essential.
Neglecting condensate drainage
Each head produces water in cooling mode. A poorly sloped or directed drain can cause leaks, odors, or wall damage. On a 3-head installation, this point becomes even more important.
Underestimating the impact of interior obstacles
A beam, a tall cabinet, a dropped ceiling, or a door opening can alter air circulation. In the Sainte-Thérèse project, the visible beam was specifically taken into account when choosing the location and orientation of the unit.
Choosing a machine without considering usage habits
Two houses of the same size can have very different needs. A family that often uses a closed office does not have the same expectations as a couple who prefers open spaces. A good HVAC project starts by listening to the client’s lifestyle.
Commissioning and final checks
After the physical installation, commissioning confirms that the three zones are working properly. This step includes communication tests, verification of heating and cooling modes, drain control, connection inspection, and explaining the operation to the client.
For a GREE FREE MATCH R32, we also check the response of each wall unit and the behavior of the outdoor unit according to simultaneous demands. A multi-zone system must be able to adapt when some rooms require heating or cooling and others are already at temperature.
This step is essential to ensure a comfortable experience from the first days of use.
Usage tips to maximize comfort
Once the TripleZone heat pump is installed, some good habits help to get the best performance from it.
It is best to use each zone according to its actual occupancy. For example, a bedroom can be set differently from a living room. It is not necessary to impose the same temperature everywhere. The advantage of a multi-zone system is precisely to create comfort adapted to each space.
We also recommend regularly cleaning the filters of indoor units. Clogged filters reduce airflow, increase the device’s effort, and decrease comfort. In a home where air conditioning is frequently used in summer, this simple maintenance makes a real difference.
Finally, periodic HVAC maintenance helps preserve system performance: inspection of the outdoor unit, cleaning coils when necessary, checking drains, and general operation control.
AirGreen’s experience on the North Shore and in Greater Montreal
AirGreen installs wall-mounted heat pumps, wall air conditioners, multi-zone systems, and residential HVAC solutions throughout the greater Montreal area, in Laval, Longueuil, on the North Shore and the South Shore. Projects like the one in Sainte-Thérèse illustrate our approach: adapting the solution to the building, not the other way around.
In some projects, the difficulty lies outside, with the location of the unit, the height relative to the snow, or the passage of pipes. In others, like here, the main challenge is inside: respecting the architecture, beams, openings, and diffusion constraints. Our job is to combine comfort, performance, and clean finishing in a single coherent installation.
This installation of a GREE FREE MATCH R32 TripleZone in Sainte-Thérèse demonstrates that a 3-zone, 3-head system can be carefully integrated into a home with distinct character. The result offers occupants better control of their comfort, a solution adapted to Quebec seasons, and a visually discreet installation despite space constraints.
