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 clean and sturdy wall installation for custom comfort in a residence in Bois-des-Filion
In Bois-des-Filion, on the North Shore, our AirGreen team recently completed the installation of a TripleZone heat pump GREE FREE MATCH R32, a 3-zone system with 3 wall-mounted heads designed to provide precise comfort in several rooms of the house without multiplying outdoor units. The project image shows the GREE outdoor unit securely installed on wall brackets against a brick and concrete facade, with well-planned clearance for maintenance, ventilation, and long-term stability.
This type of HVAC installation requires more than just equipment placement. In a multi-zone configuration, every detail matters: the location of the outdoor unit, the routing of refrigerant lines, condensate drainage, electrical supply, line length balancing, and coordination between the three indoor heads. It is precisely in this kind of project that AirGreen’s experience in heat pumps, wall-mounted air conditioners, residential heating and cooling proves invaluable.
The residence required a solution capable of serving multiple living spaces with a single outdoor unit. The choice of the GREE FREE MATCH R32 model was a very relevant option for homeowners who want to combine efficiency, installation flexibility, and room-by-room comfort.
Why a GREE FREE MATCH R32 TripleZone was suitable for this project
The GREE FREE MATCH R32 series is designed for multi-zone installations where multiple indoor units are connected to a single outdoor unit. In this project in Bois-des-Filion, the installed system manages three distinct zones, each controlled separately.
A single outdoor compressor for three comfort zones
One of the great advantages of a TripleZone heat pump is the reduction of outdoor clutter. Instead of installing three independent outdoor units, the customer benefits from a single GREE device, neatly installed on the exterior wall. This improves the overall appearance, simplifies maintenance, and reduces the visual impact on the property.
In the photo, several important elements can be seen:
- The outdoor unit is fixed on solid metal wall brackets;
- The mounting height limits risks related to snow accumulation on the ground;
- The unit is placed against a brick and concrete structure, which requires precise mounting;
- The clearance around the fan allows adequate air circulation;
- The AirGreen label confirms a professional and monitored installation.
This type of installation is particularly useful on the North Shore, where winters impose real constraints on outdoor equipment. Leaving the unit too close to the ground can cause problems with snow, ice, or drainage. A well-executed wall installation helps extend the equipment's lifespan and facilitates future HVAC maintenance interventions.
A more current R32 technology for residential installations
The GREE FREE MATCH R32 model uses the R32 refrigerant, a fluid increasingly present in modern wall-mounted heat pump and residential air conditioning systems. In an installation like this, the choice of R32 fits a logic of efficiency and performance, with a design adapted to the current needs of Quebec homes.
For the client, the goal was clear: to obtain a reliable solution to cool in summer and heat in mid-season, while maintaining independent control of the rooms. A 3 zones, 3 heads configuration allows, for example, serving a living room, a master bedroom, and an office, or a main floor combined with two closed spaces each requiring their own temperature.
A concrete response to the needs of modern families
In many residences in Montreal, Laval, Longueuil, the North Shore and the South Shore, occupants do not use all rooms in the same way. A bedroom can be too warm in the evening, an office may require more air conditioning during working hours, while an open living room needs more consistent airflow.
The GREE FREE MATCH R32 TripleZone heat pump fits this reality well. Each indoor head operates according to the needs of its zone, avoiding overcooling or overheating the entire house. This flexibility can improve daily comfort and contribute to smarter energy use.
The specific challenges of this installation in Bois-des-Filion
Each building imposes its own constraints. In this project, the presence of an exterior wall made of brick and concrete required a precise approach. A multi-zone heat pump outdoor unit is heavy and must be securely mounted. Our technicians therefore paid special attention to selecting anchor points, leveling the supports, and the overall stability of the installation.
The space available under a window also required good planning. The unit had to remain accessible without hindering the opening, the facade, or existing elements. The positioning visible in the photo demonstrates a compact, stable installation well integrated into the building.
Pipe management and installation protection
For a 3-zone system, the routing of refrigerant lines is an essential step. Each indoor head must be connected to the outdoor unit, which requires rigorous organization of the lines, communication cables, and drains. A planning error can cause unnecessary lengths, excessive bends, vibration risks, or drainage problems.
At AirGreen, we plan the routing of the pipes before starting the work. This step helps reduce drilling, limit visual impact, and ensure a cleaner finish. In a multi-zone project, this planning is even more important because three indoor units must operate harmoniously with a single outdoor unit.
An installation designed for future maintenance
One often overlooked aspect in an HVAC installation is future access to the equipment. However, a well-installed system must be able to be inspected, cleaned, and maintained without excessive difficulty. In this project, the GREE outdoor unit was installed at a height and clearance allowing reasonable access to the main components.
Good HVAC maintenance includes in particular:
- cleaning the filters of the indoor units;
- inspection of condensate drains;
- verifying the operation of the fans;
- checking the supply air temperatures;
- visual inspection of connections and piping;
- cleaning the outdoor unit when necessary.
A clean installation from the start makes all these steps easier and reduces the risk of long-term problems.
Mistakes to avoid with a TripleZone heat pump
A 3-zone heat pump is not a device to install lightly. Several mistakes can compromise system performance or durability.
The first mistake is improperly positioning the indoor units. A unit installed too close to an obstacle, too near a low ceiling, or in a poorly oriented hallway can distribute air poorly. Comfort depends as much on the chosen model as on the exact placement of each indoor unit.
The second mistake is underestimating the importance of drainage. In cooling mode, each indoor unit produces condensate. This water must be properly drained. A poorly sloped or unprotected drain can cause backflow, odors, or water damage.
The third mistake is neglecting line lengths. In a multizone system, the distances between the outdoor unit and the three indoor units must comply with the manufacturer's specifications. Poor planning can reduce system efficiency or complicate commissioning.
The fourth mistake is choosing capacity solely based on the total area of the house. In reality, zones must be analyzed separately: solar orientation, insulation, ceiling height, number of windows, usage habits, and room layout.
The importance of professional commissioning
Once the equipment is installed, commissioning is a crucial step. Our technicians check the operation of the three zones, communications between units, temperatures, heating and cooling modes, as well as the response of remote controls or associated controls.
For a GREE FREE MATCH R32, this step confirms that each indoor unit responds correctly to commands and that the outdoor unit modulates according to actual demand. Commissioning is not a formality: it ensures that the system delivered to the customer operates as intended.
Subsidies and potential eligibility
Several models of heat pumps may be eligible for subsidy programs depending on current criteria, the installed configuration, and recognized lists at the time of application. For an installation like this, AirGreen assists clients in verifying the necessary information, including model numbers, detailed invoices, and useful documents after installation.
Since amounts and conditions may vary, we always recommend verifying final eligibility at the time of the project. Our role is to provide a compliant installation, a clear invoice, and the technical information required to facilitate the client’s procedures.
A discreet, solid, and professional result
The final result in Bois-des-Filion clearly illustrates what we aim for in every project: a reliable, well-aligned, clean installation designed for Quebec’s real conditions. The GREE outdoor unit, installed on wall brackets, offers a neat appearance while maintaining the necessary clearances for proper operation.
For the customer, the improvement is felt daily: three separately controlled zones, a single outdoor unit, better-distributed air conditioning, and an effective supplemental heating solution according to seasonal needs. The home gains comfort without requiring multiple visible units outside.

Practical advice after installation
To fully enjoy a TripleZone heat pump, we recommend that homeowners use the three zones according to their actual occupancy. It’s not necessary to set all rooms to the same temperature. The advantage of a multizone system is precisely to create distinct atmospheres.
We also recommend regularly cleaning the indoor unit filters, especially during periods of heavy use in summer. Reduced airflow can decrease comfort and force the device to work longer.
Finally, periodic maintenance helps preserve system performance. A clean outdoor unit, clear drains, and well-maintained filters contribute to keeping a heat pump efficient, quiet, and durable.
An installation that reflects the current needs of North Shore homes
This GREE FREE MATCH R32 TripleZone heat pump project in Bois-des-Filion very well represents the requests we increasingly receive: homeowners who want to improve their comfort without installing multiple independent systems, reduce outdoor clutter, and benefit from more precise room-by-room control.
The installed solution meets these priorities with a clear configuration: 3 zones, 3 heads, one GREE outdoor unit. For a house on the North Shore, this type of installation offers an excellent balance between performance, flexibility, and architectural integration.
At AirGreen, we see every installation as a custom project. It’s not just the brand or model that determines success: it’s how the equipment is chosen, positioned, connected, checked, and explained to the customer. In Bois-des-Filion, this approach made it possible to deliver a reliable, clean system tailored to the real expectations of the occupants.
