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 GREE wall unit installed precisely in a tight indoor space, at the heart of a TripleZone project in Auteuil
In Auteuil, in the northern sector of Laval, our AirGreen team carried out the installation of a TripleZone heat pump GREE FREE MATCH R32, configured with 3 zones and 3 indoor units. This installation illustrates an essential aspect of residential HVAC work: successfully integrating a high-performance system into an existing home, while respecting the interior layout, wall constraints, room aesthetics, and the real comfort of the occupants.
The photo shows one of the wall units installed inside. The GREE unit is positioned high, near the ceiling, in a corner of the room where the available space was limited by a wall return on the left and a wooden piece of furniture located just below. The lines pass discreetly to the left side, with a clean and well-controlled wall penetration. This type of detail may seem simple at first glance, but it requires very precise execution: the unit must be perfectly leveled, accessible for HVAC maintenance, sufficiently clear to ensure good air diffusion, and installed in a way that does not interfere with the daily use of the room.
In this project, the choice of a GREE FREE MATCH R32 in TripleZone configuration allowed to meet a common need in Laval homes: improving comfort in several rooms without multiplying outdoor units. The owners wanted a solution that could manage different zones of the house with more flexibility than a single wall unit. One room may need air conditioning in the afternoon, another may require more heating in the evening, while a bedroom may need a more stable temperature during the night. Thanks to the three indoor units, the system can adapt comfort according to the use of each space.
An indoor installation where every centimeter counted
The image highlights a very concrete constraint: the wall unit had to be installed in a tight space, with little clearance between the ceiling, the side wall, and the furniture. In this kind of situation, our job is not just to fix the unit to the wall. We first have to check the recommended clearances, the available height, the opening of the front panel, access to the filters, and the direction of the airflow.
A wall-mounted heat pump must be installed high enough to distribute air well, but not so high as to make maintenance difficult. It must be close to a possible passage to the outside, but without compromising the interior finish. It must also be carefully aligned, as a slightly tilted unit can cause condensate drainage problems or give the impression of sloppy work. In this room in Auteuil, the chosen location achieved a balance between efficiency, discretion, and accessibility.
The wooden furniture under the unit added an extra constraint. It was necessary to avoid blocking the airflow directly or having the unit too low compared to the object below. Our team therefore positioned the head at a height that allows good air projection into the room. The result is a neat, well-integrated installation that preserves the use of the furniture while providing much more precise comfort.
Why a TripleZone configuration was suitable for this house in Laval
In many residences in Auteuil, heating and cooling needs vary greatly from one area to another. Houses may have bedrooms upstairs, living areas on the ground floor, rooms partially exposed to the sun, cooler basements, or workspaces used at specific times. A single-zone system can improve comfort in a main room, but it quickly reaches its limits when trying to stabilize temperature in multiple areas.
The TripleZone GREE FREE MATCH R32 heat pump allows three indoor units to be connected to a single compatible outdoor unit. This approach reduces outdoor clutter, simplifies integration on the property, and gives occupants better room-by-room control. The three zones can be used according to actual needs, avoiding overcooling or overheating one part of the house just to compensate for discomfort elsewhere.
For the customer, this flexibility is one of the most appreciated advantages. One zone can be set differently from another. A bedroom does not necessarily need the same temperature as a living room. A rarely used room can remain at a more moderate setting. A space occupied all day can benefit from more constant operation. This zone-by-zone logic makes the system more pleasant to use and better suited to daily life.
Important features of the GREE FREE MATCH R32
The GREE FREE MATCH R32 is part of the multi-zone systems designed to offer a flexible solution in heating and air conditioning. Its operation is based on Inverter technology, which allows the compressor to modulate its capacity according to demand. Instead of operating only by frequent stops and restarts, the system adjusts its effort to maintain a more consistent temperature.
The refrigerant R32 is also an important element of this generation of equipment. It is used in many recent systems for its thermodynamic properties and efficiency suited to modern devices. For owners, this means a current solution designed to meet expectations of efficiency, comfort, and compatibility with new residential configurations.
As with any multi-zone system, the exact data in BTU, seasonal efficiency, and eligibility for a subsidy depend on the precise combination of the outdoor unit and the three indoor units. In a 3 zones – 3 heads installation, it is essential to validate the capacity of each head according to the room served, the length of refrigerant lines, heating and cooling needs, as well as the data recognized in the applicable lists. At AirGreen, this validation is done before installation so that the customer receives a consistent, well-sized configuration adapted to their building.
An indoor unit designed for comfort, not just appearance
The position of a wall-mounted unit directly influences the customer experience. In this installation in Auteuil, the device was not placed solely based on wall availability. We evaluated how the air would circulate in the room, the presence of furniture, the proximity of the ceiling, and the technical passage to the outside.
Good air distribution helps avoid areas that are too cold or too hot. It also reduces the feeling of direct drafts, especially when the unit is installed in a room where occupants spend a lot of time. The air outlet flap must be able to direct the air effectively without immediately hitting an obstacle. Positioning it high helps distribute air throughout the room, while proximity to the corner allows for a more discreet integration.
In the photo, the digital display visible on the unit shows that the system is running. This discreet display makes daily use easier, as the customer can quickly see the setting or status of the device. This kind of detail contributes to user comfort, especially in an installation where several zones are controlled separately.
The technical challenges of a successful multizone installation in Auteuil
Drill cleanly, connect properly, and protect the interior finish
The line passage to the left of the unit visible in the photo shows a critical step: the connection between the indoor unit and the outdoor pipes. The drilling must be precise, clean, and well oriented. It must allow the passage of refrigerant lines, communication wiring, and condensate drain, while preventing air or water infiltration.
In an existing house, this step requires great care. It is necessary to consider what is behind the wall, the location of studs, potential obstacles, interior finishing, and the external path. A poorly placed opening can complicate installation, harm aesthetics, or cause drainage problems. In this room, the passage was made compact and discreet, without creating unnecessary detours inside.
Careful attention to the indoor connection is particularly important on a TripleZone heat pump, as each unit has its own technical path. A repeated mistake across several zones can quickly lead to drainage, noise, efficiency, or finishing issues. Our approach is therefore to treat each unit as a complete installation while maintaining an overall view of the system.
Coordination between the three indoor units
Installing three heads does not simply mean repeating the same action three times. Each zone has its constraints: available height, wall type, distance to the outdoor unit, room usage, desired noise level, airflow direction, and accessibility. In this project in Auteuil, the unit shown in the photo represented one of the most delicate locations due to the corner wall and furniture.
Coordination between the three zones allows for a balanced system. Line lengths must be planned, connections must respect the manufacturer's limits, and the heads must be correctly matched to the outdoor unit. A poor match between connection ports and zones can cause communication errors or inconsistent operation. That is why commissioning a multi-zone system requires a structured method.
Vacuuming and operation verification
After the mechanical installation, commissioning is a decisive step. We perform the necessary checks on connections, sealing, vacuuming, and communication between components. Each indoor head is then tested to confirm its operation, ventilation, response to controls, and behavior in cooling or heating according to current conditions.
On a GREE FREE MATCH R32 TripleZone, this step is essential because the outdoor unit must manage three distinct demands. We check that each zone responds correctly, that the air outlet temperatures are consistent, that the drains work well, and that no abnormal noise is present. This thoroughness prevents delivering a system that is only partially validated.
Mistakes to avoid with a 3-head heat pump
Several owners in Montreal, Laval, Longueuil, the North Shore, and the South Shore compare heat pump options by focusing first on price or brand. These factors matter, but the quality of the installation remains crucial. The most common mistakes in multi-zone projects are as follows:
- choose BTU capacities without analyzing each room;
- installing a head too close to a ceiling or obstacle without checking air diffusion;
- neglecting access to the filters for HVAC maintenance;
- misorienting the condensate drain;
- unnecessarily lengthening the refrigerant lines;
- forgetting to check the exact combination for grants;
- installing the outdoor unit without considering the three connected zones;
- placing a head in the technically correct spot, but in the wrong place for occupant comfort.
In this installation in Auteuil, the location visible in the photo clearly shows the importance of thoughtful work. The available wall space was limited, but the head was installed in a way that preserves air circulation, access, and finish.
Grants and eligibility for a multizone installation
Owners who invest in a heat pump often want to know if their system may be eligible for financial aid. For multizone systems like the GREE FREE MATCH R32, eligibility depends on the exact installed combination, recognized performance, current lists, and the requirements of the program applicable at the time of the work.
At AirGreen, we assist customers with this verification. We avoid approximations, especially with 3 zones – 3 heads systems, because each combination can influence the official data. This approach allows the customer to better understand the documents to keep, the information to submit, and the steps to follow after installation.
Usage tips after installation
Once the system is running, a few simple habits help preserve comfort and performance. We recommend regularly cleaning the filters of the indoor units, not blocking the airflow with furniture or curtains, and using stable settings rather than repeated extreme changes.
In the case of the head visible in the photo, the furniture located under the device must remain sufficiently clear so as not to hinder air circulation. It is also preferable to keep access to the front panel of the unit so that filter cleaning remains simple. A well-maintained system offers better efficiency, quieter operation, and a longer lifespan.
For a TripleZone heat pump, it is also useful to adapt each zone to actual habits. A bedroom can be set differently from a living room. An unoccupied zone does not need the same level of air conditioning or heating. This thoughtful use allows you to fully enjoy the multi-zone advantage.
