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 Multi-Zone Solution Precisely Installed in a Terrebonne Home
In Terrebonne, AirGreen completed a full HVAC installation of a GREE FREE MATCH R32 5-Zone heat pump, accompanied by 5 wall-mounted units strategically distributed throughout the residence. This project perfectly illustrates what many North Shore homeowners are looking for: room-by-room comfort, better control of energy consumption, a clean installation, and discrete visual integration into each living space.
The photo of this installation shows one of the wall-mounted units installed high up, on a wall adjacent to a window. This detail is important, as the location of an indoor unit should never be chosen randomly. In this room, we had to consider the window, the curtain rod, ceiling clearance, air diffusion, potential furniture, and the technical path to the outside. The result is a simple, well-aligned installation that respects the space without compromising performance.
In a home equipped with a 5-Zone system, each wall-mounted unit plays a precise role. The objective is not just to add air conditioning to several rooms, but to create a coherent comfort network, capable of adapting heating and cooling to the real needs of the occupants. In Terrebonne, this approach was particularly relevant, as the house had several zones with different uses: bedrooms, common areas, and rooms exposed to the sun differently.
Why the GREE FREE MATCH R32 system was suitable for this project
The GREE FREE MATCH R32 model is designed for multi-zone residential installations where flexibility is essential. It allows connecting multiple indoor units to a single outdoor unit, which avoids multiplying outdoor equipment while offering independent control indoors.
For this installation in Terrebonne, choosing a 5-Zone - 5 head heat pump met several specific needs:
- providing stable comfort in different rooms;
- avoiding temperature differences between floors or distant areas;
- reducing reliance on existing heating or cooling systems;
- improving comfort during hot and cold periods;
- allowing each occupant to adjust the temperature according to room usage;
- maintaining a clean and tidy interior appearance.
The GREE system's inverter technology allows the heat pump to modulate its capacity according to demand. Instead of operating only at full intensity, the system adjusts its speed to maintain a more constant temperature. In a multi-zone configuration, this modulation is particularly useful: if only one room requires a slight adjustment, the system can respond more subtly than a traditional on-off unit.
The R32 refrigerant also represents a significant asset. It is used in many modern systems for its good thermal efficiency and improved environmental potential compared to some older refrigerants. For owners who want a current and efficient solution, the GREE FREE MATCH R32 offers an interesting balance between efficiency, flexibility, and comfort.
A Wall-Mounted Unit Installed Near a Window: A Technical Choice Requiring Experience
The provided image shows a GREE wall-mounted unit installed near a window in a bright room. This configuration requires particular attention. A window naturally influences heat gain in summer and heat loss in winter. An indoor unit placed in this zone must therefore be positioned to ensure good air circulation, without creating uncomfortable drafts or interfering with curtain use.
In this project, our team took care to respect several elements:
- clearance above and around the unit;
- space required for the rod and curtains;
- airflow orientation;
- visual alignment on the wall;
- future access to filters for HVAC maintenance;
- feasibility of refrigerant line passage;
- finishing around the penetration and connections.
This type of detail distinguishes a quick installation from a truly professional one. A wall-mounted heat pump can be very efficient on paper, but if the unit is poorly placed, the felt comfort will be inferior. Conversely, a well-thought-out location allows the unit to work more efficiently, with fewer unnecessary cycles and better air distribution.
The Challenges of a 5-Zone Installation in an Existing Home
Installing a 5-Zone heat pump in an already built house requires much more extensive planning than a single-zone installation. Each indoor head must be connected to the outdoor unit by refrigerant lines, communication wiring, and a condensate drainage system. The more zones there are, the more important coordination becomes.
In Terrebonne, as in many homes on the North Shore, architectural constraints can vary from room to room. Some units must be installed near windows, others in bedrooms, and still others in spaces where passage options are limited. Our job is to find the best routes while minimizing visible impacts inside and out.
The main challenges of a project like this include:
- choosing the best location for each head;
- managing line lengths;
- coordination between the five indoor units and the outdoor unit;
- discrete line routing;
- reliable condensation drainage;
- protection of outdoor lines;
- electrical compliance;
- full commissioning of each zone.
In a multi-zone installation, an error on a single head can affect the overall customer experience. That's why AirGreen proceeds methodically, from planning to final testing.
An HVAC installation designed for daily comfort and durability
Needs analysis before unit installation
Before starting work, our team analyzes the actual needs of the house. Area is only one factor. We also consider insulation, room orientation, ceiling height, number of occupants, lifestyle habits, and interior layout.
In a Terrebonne home, temperature differences can be significant between sun-exposed rooms and those on the shadier side. A bedroom near a window can quickly warm up in summer, while another zone may remain cooler. The GREE FREE MATCH R32 5-Zone system makes it possible to correct these differences with more precision than a single air conditioning point.
This approach is particularly appreciated by families who do not want to over-cool the entire house to make a single room comfortable. With five wall-mounted units, each space can be adjusted according to its actual use.
Interior Installation: Cleanliness, Alignment, and Discretion
One of the most visible elements in a wall-mounted air conditioner or heat pump installation is the quality of the interior mounting. A poorly aligned unit, too low, or illogically placed can detract from the room's appearance. In the photo, the GREE unit is installed high up, with a limited visual presence. It does not block the window, does not interfere with curtains, and maintains a clean appearance in the room.
At AirGreen, we place great importance on this finish. Our technicians don't just make the equipment work. They also strive to respect the client's space. In a bedroom, office, or living room, the unit must be practical, accessible, and aesthetically acceptable.
This attention is even more important when there are five heads to install. The ensemble must remain coherent throughout the house. The client must feel that the system was conceived as a global solution, and not as a series of independent installations.
Management of Refrigerant Lines and Drains
In a multi-zone installation, refrigerant lines represent an essential part of the work. Each wall-mounted unit must be connected to the outdoor unit, and these connections must be made with precision. The lines must be properly insulated, protected, and organized to ensure the system's long-term performance.
Drain management is just as important. In cooling mode, each indoor unit produces condensate water. This water must be reliably drained, without risk of backup or infiltration. Whenever possible, we prioritize well-sloped gravity drains. When the configuration requires it, other solutions can be considered, but they must always be installed rigorously.
Poor condensate management can cause visible problems several weeks or months after installation. This is why this step is taken seriously from the outset.
Commissioning the GREE FREE MATCH R32 System
After the physical installation of the equipment, commissioning confirms that each component is functioning correctly. On a 5-Zone system, this step is particularly important, as each head must communicate with the outdoor unit and respond to its commands.
Our checks include:
- checking refrigerant connections;
- verifying airtightness;
- vacuum quality;
- opening and validating the refrigerant circuit;
- electrical connections;
- communication between units;
- drain flow;
- heating operation;
- cooling operation;
- sound level;
- remote control response;
- zone stability.
This procedure allows the client to use their system immediately with confidence. It also allows for the detection of any necessary adjustments before the project is completed.
Practical advice given to the client
Once the installation is complete, we take the time to explain how the system works. A multi-zone device is simple to use daily, but a few good habits can lead to better performance.
We particularly recommend:
- cleaning filters regularly;
- avoiding setting extreme temperatures;
- keeping doors open or closed depending on the desired comfort strategy;
- clearing the space around indoor units;
- not blocking airflow with curtains or furniture;
- monitoring snow accumulation around the outdoor unit;
- scheduling professional periodic HVAC maintenance.
In the room visible in the photo, the presence of curtains near the unit requires simple attention: ensure they do not block the air intake or outlet when the unit is operating. This detail may seem minor, but it influences comfort and efficiency.
Mistakes to Avoid When Choosing a 5-Zone Heat Pump
Many homeowners in Montreal, Laval, Longueuil, on the North Shore, and on the South Shore contact us after comparing different multi-zone systems. One of the most common mistakes is choosing solely based on price, without considering design quality.
A 5-Zone heat pump must be selected and installed according to the actual needs of the building. It is important to avoid:
- undersizing or oversizing certain zones;
- placing heads only where installation is easiest;
- neglecting drains;
- ignoring electrical constraints;
- choosing a poorly positioned outdoor unit;
- forgetting future access for maintenance;
- unnecessarily multiplying line detours;
- entrusting the project to a team unfamiliar with multi-zone installations.
A well-designed installation provides comfort for many years. A poorly planned installation can create problems with noise, performance, drainage, or appearance. Our role is to prevent these problems from the planning stage.
Subsidies and Potential Eligibility
Depending on the exact model, installed configuration, and current criteria, certain heat pumps may be eligible for financial assistance programs in Quebec. For high-performance systems like the GREE FREE MATCH R32, it is important to verify eligibility at the time of quotation, as requirements can change.
AirGreen supports its clients by providing the necessary information when the system is eligible: model numbers, detailed invoice, installation description, and relevant documents. This assistance is appreciated by homeowners who want to benefit from available programs without getting lost in administrative details.
