Installation of a GREE FREE MATCH R32 DoubleZone 2-head heat pump in Dollard-des-Ormeaux in the West Island of Montreal

A DoubleZone installation in full preparation, at the heart of a bright house in Dollard-des-Ormeaux

In Dollard-des-Ormeaux, in the West Island of Montreal, our AirGreen team completed the installation of a DoubleZone heat pump GREE FREE MATCH R32, consisting of 2 zones and 2 wall units. This type of project requires careful planning, especially in a house where interior aesthetics, surface protection, and the quality of the final result are as important as the technical performance of the system.

The photo taken during the intervention shows a very representative stage of the actual work on site: one of the wall units is open, the front panel is removed, the evaporator fins are visible, and the team is working with thick protection installed in front of the work area. This image clearly illustrates a reality that many clients do not always see: a professional HVAC installation is not just about mounting a unit on the wall. It involves precise handling, internal adjustments, coordination between inside and outside, and great attention to the cleanliness of the site.

In this project, the choice of a GREE FREE MATCH R32 allowed us to meet a clear need: to provide effective comfort in two distinct zones of the house, without installing two separate outdoor units. For a residence in Dollard-des-Ormeaux, where houses often have open areas, very bright front rooms, extensions, floors, or separate living zones, a 2-head configuration often represents a very relevant solution.

Why a DoubleZone heat pump was the right choice for this house

A single wall unit can work very well for some open spaces. But when the house has two zones that do not respond the same way to heat, cold, or sunlight, a DoubleZone system becomes much more interesting.

In this installation in Dollard-des-Ormeaux, the goal was to give occupants better control of comfort in two areas of the residence. A DoubleZone heat pump allows each wall unit to operate according to the needs of its zone, rather than forcing a single device to compensate for the entire house.

Specifically, this brings several advantages:

• more stable comfort in two different spaces;
• better distribution of cooled air in summer;
• more targeted heating during cold periods;
• independent temperature management;
• a single outdoor unit instead of two separate systems;
• cleaner integration around the house;
• consumption better adapted to the actual use of the rooms.

For homeowners, this flexibility is often decisive. One living area can be used mainly during the day, while another can be prioritized in the evening. With two heads, the house becomes easier to control without creating significant temperature differences between spaces.

The GREE FREE MATCH R32 model: a flexible solution for multi-zone installations

The GREE FREE MATCH R32 system is designed for configurations where multiple indoor units are connected to a single outdoor condenser. In this installation, the 2 zones – 2 heads configuration allowed for an effective balance between performance, comfort, and ease of integration.

The refrigerant R32 is an important element of this generation of devices. It is used in several recent wall-mounted heat pump systems and meets current requirements for efficiency and performance. In the Quebec residential context, where equipment must be reliable for both cooling and heating, choosing a well-designed and well-installed system plays a major role.

The FREE MATCH range from GREE is particularly interesting for homes that require more than one zone but want to avoid multiplying outdoor units. The outdoor unit becomes the system's center, while the wall units ensure comfort distribution inside.

At AirGreen, we recommend this type of system when it truly matches the home's configuration. A multi-zone installation should be chosen for good reasons: volume to be treated, room layout, constraints of refrigerant line routing, distance between zones, occupants' needs, and technical feasibility.

A delicate indoor intervention: protect, dismantle, adjust, validate

The site photo clearly shows that we were in an important technical phase. The wall unit is open, allowing access to the internal components needed for connections, checks, and adjustments. You can also see a large protective cover installed in front of the workspace, with a ladder and tools placed within reach.

This working method is essential. When an installation is done in an occupied home, especially in a finished room with windows, furniture, floors, and decorative elements, protecting the premises is an integral part of service quality.

Before starting the wall work, we secured the area to reduce the risks of dust, marks, or debris. Drilling the wall, running the lines, adjusting the bracket, handling the indoor unit, and connecting the components must be done precisely but also with respect for the client's environment.

A good HVAC installation is noticeable both by the system's performance and by how the site is left at the end of the work.

The importance of the right location for each wall unit

The positioning of the two wall-mounted units is one of the most important decisions in a DoubleZone installation. A poorly placed wall unit can cause discomfort, even if the machine itself is of good quality. The air may be directed to an unhelpful area, blocked by a beam, limited by a door opening, or sent directly onto a resting space.

In this house in Dollard-des-Ormeaux, one of the wall heads was installed near a bright area, with particular attention paid to the available space around the unit. The presence of a visible wooden beam nearby highlights a common challenge in West Island homes: working with existing architectural elements without compromising air distribution.

A wall head must be installed:

• at a height consistent with the room;
• on a solid and stable surface;
• with sufficient clearance for return and supply air;
• in a location accessible for HVAC maintenance;
• with proper slope and passage for drainage;
• without creating significant visual conflict in the room;
• taking into account furniture, windows, beams, and openings.

Our team therefore worked with both technical and aesthetic logic. The goal was not just to install the device but to integrate it into the room in a clean, durable, and efficient way.

A multi-zone project where every detail influences the final performance

A GREE FREE MATCH R32 DoubleZone heat pump requires more coordination than a single-zone system. Two indoor units must be connected, refrigerant lines, communication cables, power supply, condensate drainage, and overall commissioning must be managed. Each component must work with the entire system.

The key steps of this installation in Dollard-des-Ormeaux

For this project, our team followed a structured work sequence to ensure a reliable result.

1. Validation of locations

Before drilling, we confirmed the locations of the wall heads, taking into account air distribution, technical access, and interior aesthetics. In a house where finished walls and decorative elements are already in place, this step avoids unpleasant surprises.

2. Protection of the work area

As shown in the photo, a large protective cover was placed in front of the wall. This measure helps limit the impact of the work on the interior of the house. It protects surfaces and makes cleaning easier once the installation is complete.

3. Installation of wall mounts

Each head must be mounted on a perfectly level support. A slightly tilted or poorly fixed unit can cause drainage problems, vibrations, or a less clean finish.

4. Routing of refrigerant lines and wiring

Routing the lines is one of the most important parts of the job. The cleanest and most logical path to the outdoor unit must be chosen, while respecting the building's constraints.

5. Connecting the indoor units

The open wall head, visible in the photo, allows access to internal connections and ensures that each connection is made correctly. This step requires precision and method.

6. Vacuuming and circuit verification

Before starting, the refrigeration circuit must be properly prepared. Vacuuming removes air and moisture from the lines, which protects the compressor and promotes better reliability.

7. Start-up and operational tests

After commissioning, we check the response of both heads, the airflow, the flaps, the remote controls, the drainage, and communication with the outdoor unit.

The specific constraints of a house in West Island

Installations in Dollard-des-Ormeaux, Pierrefonds, Pointe-Claire, Kirkland, or Beaconsfield often have similar characteristics: bright houses, large windows, sometimes thick exterior walls, renovated spaces, architectural additions, exposed beams, and high aesthetic requirements.

In this context, the installation of a wall-mounted heat pump must be planned with great care. It is necessary to avoid placing a unit too close to a window if it hinders the passage of ducts, but also avoid placing it too far away to prevent loss of efficiency or unnecessarily complicate the lines.

The wooden beam visible on the right of the photo is a good example of an element to consider. It must not interfere with future service or air circulation. The space between the wall head, the ceiling, and the surrounding elements must be sufficient to allow proper operation.

A clean finish despite an open technical intervention

An open wall head during installation may seem impressive, but it is a normal step. The panels are removed to allow connection and checks. What matters is the quality of the finish once the device is closed, fixed, cleaned, and tested.

Our technicians ensure that:

• The cables are correctly positioned;
• The components are properly put back in place;
• The panels close without resistance;
• The wall around the unit remains clean;
• The external ducts are protected;
• the water drainage works properly;
• the indoor unit is stable and quiet;
• the settings are explained to the customer.

The goal is always to deliver an installation that feels like it was planned from the start, even when added to an existing house.

Performance, comfort, and efficiency: what customers really look for

Customers who contact us for a DoubleZone heat pump are not just looking for a machine. They usually want to solve a specific problem: a room that is too hot, an uncomfortable floor, a bedroom that is hard to cool, a living room that cools poorly, or an energy bill they want to better control.

In this installation in Dollard-des-Ormeaux, the GREE FREE MATCH R32 solution meets these needs more precisely than a single-zone system. Each head can be adjusted according to the preferences of the zone it serves. This independence makes comfort more convenient on a daily basis.

Zone management is especially useful when:

• the occupants do not use all the rooms at the same time;
• a section of the house receives a lot of sunlight;
• a bedroom needs to stay cooler at night;
• an open living area requires wider distribution;
• one floor heats up faster than the ground floor;
• the house has been expanded or renovated over the years.

Subsidies and eligibility: the importance of validating the exact combination

Heat pump systems can sometimes be eligible for subsidy programs, especially when they meet the applicable criteria and the combination of units is recognized. For a multi-zone system like the GREE FREE MATCH R32, it is important to verify the exact configuration: outdoor unit, indoor heads, capacity, certification, and criteria in effect at the time of the project.

At AirGreen, we support customers by providing the necessary information for their procedures when the installed system is eligible. We place great importance on transparency: subsidies must be confirmed based on the exact model data and program conditions, not just the brand.

For owners in Montreal, Laval, Longueuil, the North Shore, and the South Shore, this check can make a significant difference in the final project calculation.

Common mistakes to avoid with a DoubleZone installation

A multi-zone installation can offer excellent comfort, but some mistakes can harm the result.

Installing the two units too close to each other

If both units cover almost the same area, the customer does not really benefit from zoning. Each unit must have a clear purpose.

Choosing locations without thinking about maintenance

Filters must remain accessible. A unit installed in a hard-to-reach place will be less well maintained, which can reduce performance over time.

Neglecting drainage

Each unit produces condensation in cooling mode. A poor slope or poorly planned drainage can cause water problems.

Underestimating wall constraints

Before drilling, you must consider the structure, obstacles, external elements, wires, pipes, and the final appearance.

Choosing based on price alone

A cheaper installation can cost more if it causes vibrations, leaks, poor finishing, or disappointing performance. The quality of the work has real value.

Why AirGreen is often chosen for this type of project

Our team installs wall-mounted heat pumps, wall air conditioners, and multi-zone systems throughout Greater Montreal. We regularly work in Dollard-des-Ormeaux, in the West Island, in Montreal, Laval, Longueuil, on the North Shore, and on the South Shore.

What sets our approach apart is the combination of technical skill and attention to detail. We know that the client judges the result on several aspects: comfort, silence, appearance, cleanliness of the site, explanations given, reliability, and after-installation service.

In a project like this, protecting the interior space, the precision of the wall mounting, and the quality of the connections are as much part of the result as the machine itself. A well-chosen GREE FREE MATCH R32 must be installed with the same rigor to offer its full potential.

Practical advice for Dollard-des-Ormeaux homeowners considering a 2-head heat pump

The most useful information is:

• the rooms you want to air condition or heat;
• the approximate area of each zone;
• current comfort issues;
• the desired placement of the wall-mounted heads;
• the possible location for the outdoor unit;
• the distance between the zones and the exterior wall;
• the presence of an accessible electrical panel;
• important aesthetic constraints;
• interior and exterior photos;
• your expectations regarding noise and discretion.

These details allow our team to offer a realistic solution, adapted to the home, rather than a generic response.

A result designed to last

This installation of a GREE FREE MATCH R32 DoubleZone heat pump in Dollard-des-Ormeaux clearly illustrates the importance of work that is prepared and executed with care. The construction site photo shows the behind-the-scenes: the open unit, the tools, the protection, the technical adjustments. It is precisely in these moments that the final quality of an installation is built.

Once the system is closed up, cleaned, tested, and explained to the client, it remains a discreet and efficient comfort solution, capable of managing two zones of the house with a single outdoor unit. For homeowners, this means better temperature control, more flexible use, and more consistent comfort throughout the seasons.

For AirGreen, this type of project represents exactly our profession: adapting the right HVAC technology to the reality of a home, carrying out a clean installation, and delivering a system that meets the concrete expectations of the occupants.
