A discreet, clean multizone installation perfectly adapted to the architecture of this residence in Candiac
In Candiac, on the South Shore, our AirGreen team carried out the installation of a GREE FREE MATCH R32 TripleZone heat pump, configured with 3 zones with 3 indoor heads. This project perfectly illustrates the type of installation where the quality of the result is measured not only by the machine’s performance but also by the precision of the outdoor integration, the neatness of the piping route, and the complete logic of the interior zoning.
The photo shows a GREE outdoor unit installed in a paved area, between various architectural elements: a wall with light cladding, a brick section, a window above, a nearby masonry column, and a black downspout on the right side. In this context, the challenge was to install the unit in a stable, accessible, and visually neat way while respecting the clearances necessary for the proper functioning of the heat pump.
We chose an installation on an elevated ground support, rather than placing it directly on the slabs. This approach protects the outdoor unit from water, snow, and ice accumulation while ensuring better air circulation around the device. In Candiac, as elsewhere on the South Shore, freeze-thaw cycles, winter storms, and snow accumulation near the foundations are factors to take seriously from the project design stage.
Why a TripleZone heat pump was particularly suitable for this house
A TripleZone heat pump is an excellent solution when several rooms in the house have different comfort needs. In this project, the 3 zones – 3 heads configuration allows air conditioning and heating of three distinct spaces from a single outdoor unit. The client wanted to improve the overall comfort of the residence without multiplying visible devices outside.
This type of system is often chosen for homes where the main living area, bedrooms, and an office or basement do not respond the same way to temperature changes. A sun-exposed room can quickly become hot in summer, while another, less exposed, stays cooler. In winter, some spaces retain heat better than others. With a multizone HVAC installation, each indoor unit can be adjusted according to the actual use of the room.
For occupants, the benefit is immediate: more control, fewer compromises, and better usage efficiency. It becomes possible to adjust comfort in a bedroom during the night, cool the main area during hot days, or heat a workspace without over-conditioning the entire house.
The GREE FREE MATCH R32 technology: flexibility and efficiency for three zones
The GREE FREE MATCH R32 series is designed to allow the connection of multiple indoor units to a single outdoor unit. This flexibility is especially useful in residential projects where one wants to avoid outdoor clutter, preserve the facade's aesthetics, or simplify future maintenance.
The refrigerant R32 is one of the important features of this installation. It is used in many recent HVAC systems and allows manufacturers to design efficient, compact equipment suited to modern air conditioning and heating needs. For AirGreen, the use of R32 also requires particular care during installation: proper handling, precise connections, complete vacuuming, pressure checks, and commissioning according to industry best practices.
The Inverter technology of this type of system allows the machine to modulate its operation according to the actual demand. Rather than operating only at full capacity or stopping abruptly, the equipment adjusts its speed. This modulation contributes to a more stable temperature, quieter operation, and better energy management when the system is properly sized.
An outdoor unit installed on a support: an important choice in Candiac
In the photo, the outdoor unit is placed on a sturdy metal support above the paving stone. This technical decision is essential. A heat pump unit installed too low can be exposed to runoff water, compacted snow, or ice. It can also become more difficult to clear in winter.
The support keeps the device at a safer height while ensuring a stable base. The paving stone under the unit provides a clean and durable surface, but it is still necessary to avoid having the device rest directly on an area likely to shift with frost or ground movements. The choice of support therefore contributes to long-term reliability.
The chosen location also takes into account circulation around the house. The unit is placed in a side space where it remains accessible without blocking a main passage. For HVAC maintenance, this accessibility is a real advantage: cleaning the exchanger, inspecting connections, checking drainage, and future interventions can be done more easily.
A neat outdoor integration between masonry, siding, and downspout
This installation in Candiac required special attention to the immediate environment. The unit is located between several surfaces and fixed elements: light brick column, pale siding wall, foundation, paving stone, window, and gutter. In such a space, each pipe must be planned to remain discreet, protected, and functional.
The path of the pipes and drainage is observed toward the right side, near the wall. The work had to be done compactly to limit visual impact while respecting technical constraints. Refrigerant pipes, communication cables, and condensation drainage must be protected from the weather and carefully organized.
A multi-zone system adds a layer of complexity: three indoor units mean several indoor and outdoor routes to coordinate. It’s not just about connecting a machine; a complete network must be designed between the outdoor unit and the comfort zones inside the house.
Planning the three indoor units: the true heart of the project
In a TripleZone heat pump, the choice of the location of the indoor heads is as important as the choice of the outdoor unit. A poorly placed head can create discomfort, blow directly on occupants, or misread the ambient temperature. Conversely, a well-positioned head can transform the comfort of a room while reducing unnecessary cycles.
For this residence in Candiac, our planning took several criteria into account:
- the area and use of each zone;
- the orientation of rooms relative to the sun;
- natural air circulation;
- drainage possibilities;
- the distance between the indoor heads and the outdoor unit;
- the final appearance of the pipes;
- access for filter cleaning;
- sound comfort in resting rooms.
This analysis is essential in a family home. The needs are not the same in an open living room, a master bedroom, or an office. Thanks to the GREE FREE MATCH R32 system, each zone can be used according to the occupants' habits rather than imposed by a single central thermostat.
Challenges specific to multi-zone installations
A 3 zones, 3 heads installation requires more coordination than a simple wall-mounted air conditioner. Pipe lengths must respect the machine's technical limits. Elevation changes must be taken into account. Drains must be routed with an adequate slope or, when necessary, with a suitable solution. Connections must be made precisely to ensure the refrigerant circuit's tightness.
The main pitfall in this type of project is to look for the shortest path without considering future maintenance or the final appearance. At AirGreen, we favor a balanced approach: technical efficiency, clean finish, and durability. This sometimes means taking more time to position the pipes more logically or to adjust the outdoor support to achieve a more stable result.
In this project, the limited outdoor space between the column, the wall, and the rainwater downpipe required a compact installation. We had to avoid any interference with the rainwater drainage and maintain sufficient access around the unit. These are precisely the details that distinguish a quick installation from one designed to last.
Electricity, safety, and commissioning
A professional HVAC installation always includes special attention to electrical supply. In the photo, you can see the connection location near the outdoor unit. For a multizone heat pump, it is essential that the power supply matches the device's capacity and that electrical protections comply with the manufacturer's requirements and applicable standards.
Commissioning is a decisive step. After connecting the pipes and wiring, our technicians perform the necessary checks: vacuuming, leak testing, validating communications between the outdoor unit and indoor heads, starting heating and cooling modes, checking drainage, and explaining the operation to the customer.
This step ensures that the three zones respond correctly, that each head is properly associated with the system, and that the machine operates according to expected parameters.

What the customer gains with a single outdoor unit
One of the major advantages of this installation is the reduction of outdoor clutter. With a single GREE unit for three indoor heads, the residence maintains a neater exterior appearance. This is especially important in residential neighborhoods like Candiac, where the aesthetics of the facade and outdoor arrangements matter a lot.
The customer also benefits from better comfort control. Instead of a central system that treats the whole house uniformly, the TripleZone heat pump allows for finer management. This flexibility can also contribute to more rational energy use, since zones can be adjusted according to actual occupancy.
Subsidies and eligibility: a check to do before each project
For homeowners considering a heat pump in Candiac, the question of subsidies often comes up. Eligibility depends on the exact combination of installed units, capacities, certified efficiencies, the reference number associated with the system, and the criteria in effect at the time of the application.
In the case of a multizone system like the GREE FREE MATCH R32, it is particularly important to validate the complete combination: outdoor unit, three indoor heads, and actual configuration. At AirGreen, we support our clients in this step by providing the necessary documents after installation, including the detailed invoice and technical information useful upon request.
We avoid promising an amount without validation, as programs can vary and each configuration must be properly examined. This transparency allows the client to make an informed decision before work begins.
Practical advice before installing a 3-zone heat pump
Before choosing a TripleZone heat pump, it is important not to rely solely on the number of rooms. Two houses of the same size can have very different needs depending on insulation, windows, orientation, ceiling height, and interior layout.
Here are the points to analyze before installation:
- the actual thermal load of each zone;
- the optimal location of the heads;
- the distance between the outdoor unit and the indoor zones;
- drainage possibilities;
- the noise perceived inside and outside;
- access for maintenance;
- the visual impact of the ducts;
- the constraints specific to the facade.
These elements help avoid common mistakes: poorly positioned head, oversized system, overly visible ducts, poorly planned drainage, or outdoor unit installed in an area too exposed to snow.
The importance of HVAC maintenance after installation
Once the heat pump is installed, regular maintenance becomes essential to preserve performance. The filters of the indoor heads must be cleaned periodically. The outdoor unit must remain clear, especially after storms or periods of strong winds that can accumulate leaves, dust, or snow around the device.
In a multizone setup, it is also recommended to check the operation of each head at the beginning of the heating and cooling seasons. Preventive maintenance helps quickly identify anomalies, maintain good air quality, and extend the equipment's lifespan.
At AirGreen, we always explain to the client the simple actions to take and the situations that require a technician's intervention. This approach reduces the risk of avoidable problems and helps owners fully benefit from their system.
