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 DoubleZone installation precisely prepared in a residential area of Pont-Viau
In Pont-Viau, in Laval, our AirGreen team completed an installation of a GREE FREE MATCH R32 DoubleZone heat pump, a 2 zones, 2 heads system designed to offer independent comfort in two distinct spaces of the house. From the moment we arrived, one thing stood out: the outdoor space was neat, greened, with a side access typical of many residential properties in Laval. The GREE boxes visible in the photo show the equipment ready to be installed: two indoor wall units and one outdoor inverter unit, carefully delivered and positioned before work began.
This type of installation requires rigorous organization. In a neighborhood like Pont-Viau, where houses may have tighter access, landscaped patios, closely spaced windows, mature plantings, and outdoor space constraints, the success of an HVAC installation depends as much on planning as on the quality of the chosen equipment.
The GREE FREE MATCH R32 is a particularly relevant multizone solution when a homeowner wants to air condition and heat two areas of the house without installing two separate outdoor units. A single outdoor unit can power two wall-mounted heads, which reduces outdoor clutter while offering finer temperature control inside.
At AirGreen, we approached this project with special attention to three priorities: occupant comfort, cleanliness of the piping layout, and the durability of the installation under the climatic conditions of Laval and Greater Montreal.
Why choose a GREE FREE MATCH R32 DoubleZone heat pump
A DoubleZone heat pump becomes interesting when two areas of the house have different needs. A room exposed to the sun can overheat quickly in summer, while a bedroom or office may require a more stable and quieter temperature. With a 2 zones, 2 heads system, occupants can adjust each space according to its actual use.
The GREE FREE MATCH R32 operates with inverter technology, which allows the outdoor unit to modulate its capacity according to demand. Rather than running only at full power and then stopping abruptly, the system gradually adjusts its speed. This modulation helps to:
- maintain a more stable temperature;
- limit uncomfortable variations;
- improve energy efficiency;
- reduce overly frequent cycles;
- offer better adaptation to the real needs of each zone.
The refrigerant R32 is also one of the important features of this generation of equipment. It is used in many recent wall-mounted heat pump and wall-mounted air conditioner systems, notably for its performance in modern devices and its integration into new HVAC ranges.
A well-organized delivery before the start of work
The photo shows the GREE boxes placed near the house, on an outdoor paved surface. This detail may seem simple, but it illustrates an essential step of the work: site preparation. Even before installation, our technicians must verify that the delivered units match the planned project, that the components are present, that the boxes have no visible damage, and that the equipment can be handled safely around the property.
In this project in Pont-Viau, the outdoor space was landscaped with plants, narrow passageways, and a residential facade to preserve. We therefore paid special attention to handling the equipment to avoid damage to existing landscaping.
A successful installation often starts with very concrete actions:
- protect the passage areas;
- place the boxes in a stable location;
- keep the equipment nearby without blocking access;
- prepare the tools before opening the units;
- plan the order of tasks to limit unnecessary trips.
This level of organization allows for cleaner work and respects the client's property.
The role of the outdoor unit in a 2-zone system
The outdoor unit of a GREE FREE MATCH R32 system plays a central role. It must supply two indoor units, manage simultaneous demands, and maintain stable performance in both heating and cooling. Its location should never be chosen at random.
For this installation in Pont-Viau, several elements were evaluated before installation:
- the necessary clearance around the outdoor unit;
- the distance between the outdoor unit and the two wall heads;
- possible routing of refrigerant lines;
- proximity to the electrical supply;
- protection against snow and water;
- the visual impact in the outdoor layout;
- future access for HVAC maintenance.
A poorly positioned outdoor unit can cause several problems: more noticeable noise, snow accumulation, limited air circulation, difficult access for maintenance, or less aesthetic routing of lines. At AirGreen, we always prioritize a solution that respects both technical requirements and the overall appearance of the property.
Two wall heads for better distributed comfort
The two indoor wall units allow the creation of two independent zones. This configuration is often ideal for homes where a single wall head is not enough to comfortably cover all important rooms.
In many homes in Laval, one head can be installed in a main open area, while a second can serve a bedroom, a floor, an office, or a room that is harder to stabilize. The goal is not just to add capacity; it is to distribute comfort where it is really needed.
A well-designed system can also reduce temperature differences between rooms. Occupants no longer need to force a single unit to cool the entire house from an imperfect location. Each zone receives a more suitable treatment, which improves daily comfort.
The technical details that make the difference
A multizone HVAC installation requires careful execution. Refrigerant lines, communication cables, condensation drainage, and penetrations must be done precisely. In the case of a DoubleZone heat pump, each indoor head must be correctly connected to the outdoor unit, and each line must meet the manufacturer's requirements.
Our technicians pay special attention to several points:
- the quality of the refrigeration fittings;
- compliance with the allowed line lengths;
- the proper vacuuming;
- the sealing of the wall passage;
- the slope of the condensation drain;
- the secure mounting of the wall units;
- the clearance in front of the indoor units;
- the complete commissioning of the system.
Good equipment cannot compensate for a sloppy installation. That’s why we consider installation, checks, and operational tests as important steps as choosing the brand or model.
A solution adapted to the homes of Pont-Viau and Laval
Pont-Viau is an area of Laval where you find several types of properties: single-family homes, duplexes, older buildings, successive renovations, compact outdoor spaces, and already developed lots. These realities directly influence how a wall heat pump must be installed.
In this project, the outdoor environment required precision. The plants, paving, window close to the work area, and side access demanded a methodical installation. Our team had to ensure a clean finish without compromising system performance.
This is one of the advantages of working with a company experienced in installations in Greater Montreal. Projects in Montreal, Laval, Longueuil, on the North Shore and the South Shore rarely require a uniform approach. Each home has its constraints, and each installation must be tailored to the building.
What this installation brings to comfort and property value
A well-installed GREE FREE MATCH R32 DoubleZone can significantly improve the quality of life in a home. In summer, it acts as a multi-zone wall air conditioner capable of cooling two key spaces. In the shoulder seasons and during much of the cold period, it can contribute to heating with better-controlled consumption than a traditional electric heating system, depending on use and conditions.
For the client in Pont-Viau, the goal was to obtain a reliable, discreet, and flexible solution. Choosing a 2 zones, 2 heads system avoids installing two separate outdoor units while offering better comfort distribution than a single-zone system.
Mistakes to avoid before installing a DoubleZone heat pump
Several owners first compare prices and brands. That's normal, but it's not enough. For a multi-zone system, you also need to assess the quality of the design.
Here are the mistakes we see most often:
- choosing a capacity without a real analysis of the zones to be served;
- neglecting the placement of wall heads;
- installing the outdoor unit too close to an obstacle;
- ignoring condensation drainage;
- underestimating the importance of duct routing;
- forgetting future access for maintenance;
- comparing quotes without checking what is included.
A lower quote can sometimes hide significant compromises: minimal outdoor protections, poorly positioned lines, less clean finishing, lack of support for warranty documents or subsidy programs. At AirGreen, we strive to clearly explain technical choices so the client knows what will be installed and why.
Subsidies and energy efficiency
Heat pump systems may be eligible for subsidies when the installed combination meets the criteria of current programs. For multizone systems, it is essential to verify the eligibility of the exact combination, including the outdoor unit and associated indoor heads.
AirGreen supports its clients in this step by providing the necessary information after installation, including the detailed invoice and available technical data. Amounts and criteria may vary depending on programs, dates, and recognized models. A thorough check avoids unrealistic expectations and allows the client to better understand the net cost of their project.
For owners in Laval, Montreal, Longueuil, the North Shore, and the South Shore, this step can significantly influence the final decision, especially when it comes to a quality multizone system.
The importance of HVAC maintenance after installation
Once the DoubleZone heat pump is installed, maintenance remains essential. The filters of the indoor units must be cleaned regularly, the drains must remain clear, and the outdoor unit must be inspected to ensure nothing is blocking airflow.
Good HVAC maintenance helps preserve:
- the system's performance;
- the quality of indoor air;
- the stability of heating and air conditioning;
- the lifespan of the equipment;
- the peace of mind of the owner.
In an area like Pont-Viau, where leaves, outdoor dust, and seasonal variations can affect equipment, regular inspection is an excellent habit. A well-done installation makes this maintenance easier because the components remain accessible.
Why choose AirGreen for an HVAC installation in Pont-Viau
Our approach is based on a simple idea: a heat pump installation must be designed for the actual home, not just a technical sheet. The system choice, unit placement, pipe protection, drainage, electricity, and finishing must all work together.
For this project in Pont-Viau, we combined the flexibility of the GREE FREE MATCH R32 with planning suited to a well-maintained residential environment. The presence of the GREE boxes in the photo tells an important step: before the final installation, everything starts with orderly preparation, equipment verification, and careful site assessment.
This method is what allows for a durable, clean, and pleasant-to-use installation. Whether in Laval, Montreal, Longueuil, on the North Shore or the South Shore, AirGreen focuses on HVAC solutions tailored to the real needs of occupants.
A project that reflects quality workmanship
This installation of a GREE FREE MATCH R32 DoubleZone heat pump in Pont-Viau perfectly illustrates the benefits of a well-chosen multizone system. Two wall-mounted heads, one outdoor inverter unit, a configuration designed for two distinct zones, and professional execution: these are the elements that provide stable comfort, good efficiency, and a clean installation.
For a homeowner who wants to improve their home's comfort without undertaking major ductwork, the 2 zones, 2 heads solution is a very serious option. It offers flexibility, more precise control, and a more discreet integration than multiplying outdoor units.
At AirGreen, we see every project as a combination of technical skill, fieldwork, and listening. This project in Pont-Viau is a good example: a well-selected GREE system, careful preparation, and an installation designed to serve the client for many years.

Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
