A discreet TripleZone installation on a side wall in Delson, designed to protect the facade and optimize three comfort zones
In Delson, on the South Shore, our AirGreen team installed a GREE FREE MATCH R32 TripleZone heat pump, configured in 3 zones with 3 indoor units. This project perfectly illustrates the type of installation where outdoor planning becomes as important as the equipment's performance itself. In the photo, the GREE outdoor unit installed along a stucco side wall is immediately noticeable, with a neat white vertical line cover running up to the upper levels of the residence. The goal was clear: to supply three distinct indoor spaces while maintaining a clean, structured, and durable exterior finish.
This type of house often presents a particular challenge: the available space on the side is functional, but it must be used precisely. The outdoor unit cannot be placed just anywhere. Airflow, access for HVAC maintenance, window positions, water downspouts, existing ducts, the electrical panel, the slope of the land, and the overall appearance of the building must all be considered. In this case, the choice of location allowed the installation to be kept away from main passage areas while facilitating connection to the three indoor units.
A multi-zone heat pump like the GREE FREE MATCH R32 perfectly meets the needs of homeowners who want to improve comfort in several rooms without installing three separate outdoor units. With a single outdoor unit, it is possible to cool and heat multiple zones independently, according to the family's lifestyle. In a house in Delson, where the seasons require both heating and cooling, this flexibility becomes a real daily advantage.
Why a GREE FREE MATCH R32 TripleZone was suitable for this project
The GREE FREE MATCH R32 range is designed for residential multi-zone installations. It allows multiple indoor units to be connected to a single compatible outdoor unit, which reduces outdoor clutter and simplifies visual integration on the building. For this project in Delson, the 3 zones – 3 heads configuration allowed treating three areas of the house with better precision than a single-zone system.
In a typical residence on the South Shore, needs can vary considerably from one room to another. A bedroom located upstairs can accumulate more heat in summer. A living room may require better heating in mid-season. A workspace, basement, or family area may have irregular use but require a stable temperature when occupied. Thanks to a TripleZone heat pump, each zone can be adjusted according to its actual use, rather than forcing the entire building to follow the same temperature.
The model uses the refrigerant R32, combined with several recent devices for their thermodynamic properties and performance suited to modern systems. The Inverter technology also allows the device to modulate its operation according to demand. In practice, this helps maintain a more consistent temperature, with fewer sudden variations and better energy consumption management than a system operating only by on-off cycles.
A controlled exterior finish on a side wall
One of the most interesting aspects of this installation is the management of the outdoor lines. In the photo, the white line cover is installed vertically on the side wall, in a straight line, with a clean finish that complements the building's architecture. This approach is not only aesthetic: it protects the refrigerant pipes, communication cables, and drains from weather, UV rays, minor impacts, and premature wear.
For a TripleZone heat pump, the outdoor routes can quickly become complex. You need to connect three indoor units to the outdoor unit, sometimes located on different levels or in different directions. If this step is poorly planned, the result can become visually cluttered, difficult to maintain, or vulnerable to drainage problems. At AirGreen, we prepare the line routes before starting work to limit unnecessary detours and maintain a neat appearance.
In this installation in Delson, the vertical line cover allows the technical passage to be grouped in an orderly manner. On a stucco wall, this precision is important because each fastener must be well aligned and carefully installed to avoid damage to the surface. The final result gives the impression of an integrated installation, not an improvised addition.
The site's particular constraints
Each HVAC installation has its own constraints. Here, the side wall offered adequate space, but it was necessary to deal with the building height, the presence of ducts near the ground, limited side access, and the need to keep the outdoor unit well ventilated. A heat pump unit must have enough clearance to efficiently draw in and expel air. A poor location can reduce performance, increase perceived noise, or complicate maintenance.
Our team also paid attention to the position of the unit relative to the wall. Even though the side space is often more discreet, it must never become too confined. The outdoor unit must remain accessible for inspections, battery cleaning, connection checks, and future interventions. This concern for accessibility is especially important on a multizone heat pump, as it supplies several rooms: any intervention on the outdoor unit directly affects the comfort of the entire house.
The vertical passage of the lines was also designed to limit the visual impact from the busiest areas of the property. In several projects in Montreal, Laval, Longueuil, on the North Shore and the South Shore, we apply the same logic: use the side walls when possible, group technical elements, and keep the main facades as clear as possible.
The key steps of a successful multi-zone installation: precision, coordination, and full commissioning
Analysis of the three zones before work begins
Before installing a GREE FREE MATCH R32 TripleZone, we must determine the exact locations of the three indoor heads. This step directly influences the final comfort. A wall head placed too close to an obstacle may poorly distribute the air. A unit installed in the wrong place can create an uncomfortable draft. A head placed without consideration can also make the outdoor lines longer or more visible.
For this house in Delson, our team evaluated the interior layout, priority rooms, distances to the outdoor unit, and passage possibilities. The goal was to obtain three truly useful zones, not just three units placed where there was space left. A good HVAC installation always starts with this reading of the building.
The role of sizing in a 3-head heat pump
Sizing a TripleZone heat pump must be done rigorously. It is not enough to roughly add up the needs of the rooms. You must consider the area, insulation, number of windows, solar orientation, ceiling height, and actual use of the zones. A bedroom does not necessarily require the same capacity as an open area. A room on the top floor may react differently than one on the ground floor.
In the case of the GREE FREE MATCH R32, the exact capacities in BTU and efficiency data depend on the precise combination between the outdoor unit and the three selected indoor heads. This is an important check on all multi-zone systems. At AirGreen, we validate the complete configuration before installation so that the customer receives a system consistent with their actual needs. This step also allows us to verify potential eligibility criteria for subsidy programs applicable at the time of the project.
Penetrations, refrigeration lines, and building protection
Installing a 3 zones – 3 heads system requires several drillings and multiple technical passages. Each opening must be made precisely, protected against infiltration, and correctly oriented to promote condensate drainage. On an exterior plastered wall, care in drilling and fixing is essential to maintain a clean finish.
Refrigerant lines must be properly insulated, protected inside line covers, and connected according to the manufacturer’s recommendations. Poor insulation can cause efficiency losses or condensation. A poor routing can complicate future maintenance. A poorly designed slope can create drainage problems. These details are not always visible once the work is finished, but they make all the difference in the installation’s lifespan.
Electrical connection and technical coordination
A multizone heat pump requires an appropriate electrical supply. The connection must meet the device’s requirements, the required rating, proper protection, and applicable standards. In the photo, you can also see electrical conduits near the bottom of the wall, which highlights the importance of carefully coordinating existing routes with the new installation elements.
At AirGreen, this coordination is an integral part of the project. We do not treat electricity as a secondary detail. A reliable installation depends on the entire system: outdoor unit, indoor units, refrigerant lines, communication, drainage, power supply, and commissioning. Each element must be consistent with the others.
Vacuuming, testing, and starting the three zones
After connection, commissioning is an essential step. On a GREE FREE MATCH R32 system, we carry out the necessary checks before full startup. This notably includes checking the connections, vacuuming the lines, verifying tightness, validating communication between the indoor units and the outdoor unit, then performing operational tests.
Each zone is tested individually. We check ventilation, response to controls, behavior in cooling mode, behavior in heating mode when conditions allow, air outlet temperatures, and the absence of unusual noise. This method prevents delivering a system that only partially works or requires correction a few days later.
Concrete benefits for the customer
Once the installation is complete, the client benefits from a system capable of managing three spaces with greater precision. Comfort becomes more flexible: one zone can be adjusted for the night, another for the hours spent in the living room, and a third for a room used only at certain times of the day. This zone management can also help limit unnecessary consumption, since not all rooms need to be treated with the same intensity all the time.
Acoustic comfort is also an appreciated factor. By installing a single well-positioned outdoor unit, noise and visual clutter are reduced compared to several separate devices. The exterior finish, with a straight and well-integrated line cover, also contributes to the perceived value of the project.
Subsidies and eligibility: an essential check
Owners in Delson, Longueuil, Montreal, Laval, the North Shore, and the South Shore are often interested in available subsidies for heat pumps. For multi-zone systems, eligibility must always be verified according to the exact installed combination, current lists, and the requirements of the applicable program.
Rather than promising an approximate amount, we favor a clear approach: validate the model, the indoor heads, the recognized efficiency, and the required documents. This rigor protects the client from unpleasant surprises and allows them to properly prepare their request after installation.
Mistakes to avoid with a TripleZone heat pump
Several problems can be avoided when a project is planned by an experienced team. Among the most common mistakes, we often see:
- installing the outdoor unit in a space that is too tight;
- placing indoor heads without considering air diffusion;
- underestimating the length and complexity of refrigerant lines;
- neglecting the protection of outdoor ducts;
- forgetting future access for HVAC maintenance;
- choosing a capacity without analyzing the actual needs of each zone;
- poorly managing condensate drains;
- ignoring the building's exterior appearance.
In this installation in Delson, each of these considerations was integrated from the start. The result is a well-positioned, well-protected system that visually matches the side wall of the residence.
Maintenance tips after installation
To keep a GREE FREE MATCH R32 heat pump in good condition, we recommend regularly cleaning the filters of the indoor units, keeping the outdoor unit clear, ensuring that the line covers remain securely attached, and scheduling periodic HVAC maintenance. Cleaning the outdoor coil, checking drainage, and inspecting connections help preserve the system's performance.
With a multi-zone installation, it is also useful to learn how to use the zones intelligently. A temperature that is too low in cooling or too high in heating does not necessarily improve comfort; it can simply increase consumption. Stable programming adapted to lifestyle habits often yields better results.
An AirGreen project representative of our approach on the South Shore
This installation of a GREE FREE MATCH R32 TripleZone Heat Pump with 3 zones and 3 heads in Delson perfectly summarizes our way of working: a thorough study of the building, a clean installation, special attention to the exterior lines, and a complete commissioning. The system was not only installed to operate; it was integrated to last, remain accessible, and maintain a professional appearance.
At AirGreen, we carry out installations of heat pumps, wall air conditioners, multi-zone heat pumps, heating and air conditioning throughout Greater Montreal, including Montreal, Laval, Longueuil, the North Shore and the South Shore. Projects like the one in Delson demonstrate the importance of entrusting an HVAC installation to a team that understands both the technical constraints and the real expectations of homeowners.
