Installation of a GREE FREE MATCH R32 DoubleZone heat pump in Delson: 2-zone system with two wall-mounted heads and an outdoor wall unit on a brick facade

A perfectly adapted multi-zone HVAC installation for a house in Delson

In Delson, this installation of a DoubleZone heat pump GREE FREE MATCH R32 was carried out in a context very representative of the residential projects we handle on the South Shore: a brick house, an exterior facade with routing constraints, an installation height to respect, two indoor zones to supply, and a visual integration to care for. The result is a clean, solid, and well-organized installation, designed to offer effective comfort in two distinct spaces of the residence.

In the photo, you can clearly see the GREE outdoor unit installed on metal wall brackets fixed to the masonry. The choice of this position frees up the ground, protects the unit from snow accumulation, and facilitates air circulation in front of the fan. The unit is placed under a window, with a well-defined duct path that goes vertically up and then moves horizontally along the facade to reach the zones served inside.

This type of installation requires excellent coordination between technical planning, brick drilling, mechanical fastening, refrigerant line routing, electrical connection, and the final aesthetics. At AirGreen, we carry out this kind of project throughout Greater Montreal, notably in Montreal, Laval, Longueuil, on the North Shore and the South Shore, with particular attention to durability, performance, and finish.

Why choose a GREE FREE MATCH R32 for a DoubleZone installation?

The GREE FREE MATCH R32 is a particularly interesting multi-zone solution for homeowners who want to heat and cool two rooms or two sections of a house with a single outdoor unit. In this installation in Delson, the system includes an outdoor unit and two indoor wall-mounted units, allowing the creation of two independent comfort zones.

This configuration is ideal when the needs are not the same from one room to another. For example, an open area on the ground floor may require a different capacity than a bedroom, an office, a basement, or a room located upstairs. Thanks to the DoubleZone system, each zone can be controlled separately, which improves comfort while avoiding unnecessary heating or cooling of the entire house.

The refrigerant R32 used by this generation of GREE systems also represents a notable advantage. It offers good thermal performance and fits within a more modern approach to HVAC equipment. For a Delson homeowner seeking a reliable, flexible solution adapted to Quebec’s climate realities, this choice is a very relevant option.

An outdoor unit mounted on brick: precision, solidity, and clearance

The installation visible in the photo highlights a central element of the project: the outdoor unit was installed directly on a brick wall using sturdy wall brackets. This method is often recommended when the ground is not an ideal location, when snow accumulation needs to be avoided, or when the outdoor layout imposes certain constraints.

Mounting an outdoor unit on a brick facade requires careful execution. The supports must be perfectly aligned, securely anchored, and capable of supporting the weight of the unit over time. A rough installation can cause vibrations, unwanted noise, or premature wear of the anchors. In this project, our team took care to install the unit at an adequate height, with enough clearance to ensure good ventilation.

The presence of the window above the unit also required precise planning. The goal was to position the unit so as not to block access to the window, to respect the necessary distances, and to maintain a clean appearance on the facade. The final result shows a clear and structured integration, without unnecessary clutter.

The external routing of the conduits: a detail that makes all the difference

On a DoubleZone installation, routing the refrigerant lines is more complex than on a single-zone system. The pipes must be routed to two indoor units while maintaining a coherent, protected, and aesthetically acceptable path. In Delson, the brick facade had an interesting feature: a dark protective conduit follows a vertical path and then makes a sharp change in direction to reach the necessary passage points.

This type of finish requires precision. The ducts must not be installed randomly. Their path must take into account:

• the exact location of the indoor units;
• the building structure;
• existing openings, such as windows;
• brick joints and possible drilling areas;
• the total length of refrigerant lines;
• protection against weather;
• the overall appearance of the facade.

In this project, the dark duct contrasts with the light brick, but it follows a clean, logical, and well-controlled line. This finish gives an impression of organized work, which is essential for a client who wants a durable HVAC installation without compromising the exterior appearance of their home.

Two indoor zones for better distributed comfort

A DoubleZone heat pump is not just for installing two units. It mainly allows better comfort adaptation to the reality of the house. In Delson, as in many residences on the South Shore, rooms can have very different thermal behaviors depending on sun exposure, insulation, ceiling height, interior layout, and occupants' lifestyle habits.

With two wall units, the client can adjust one zone without necessarily changing the other. This is particularly useful in several situations:

• a bedroom that needs to stay cooler at night;
• a living room that receives a lot of afternoon sun;
• an office used only during the day;
• a basement cooler than the ground floor;
• a room far from the main heating source;
• a house where the occupants do not all have the same temperature preferences.

This flexibility is one of the great advantages of ductless systems. Rather than relying on a single distribution point, the client gets a more balanced, precise solution better suited to the daily use of each space.

The key steps of this installation in Delson

An installation like this takes place in several stages, each having a direct impact on the final system performance.

Needs analysis and positioning validation

Before installation, our team checks the areas to be served, the required capacity, the possible location of the indoor units, and the optimal positioning of the outdoor unit. In a brick house, this step is essential because drilling and running the pipes must be planned before starting the work.

Installing the indoor wall-mounted heads

The two heads must be installed in strategic locations to ensure good air distribution. A poorly positioned head can create uncomfortable zones, drafts, or uneven performance. We always favor a location that promotes natural air circulation in the room.

Drilling and routing refrigerant lines

Drilling the brick requires appropriate tools and a careful method. The opening must be clean, well positioned, and properly sealed to prevent air or water infiltration. The refrigerant lines, communication wire, and drains must then be routed safely.

Mounting the outdoor unit

The GREE unit was mounted on wall brackets, with particular attention to alignment, anchor strength, and necessary clearance. This step is crucial to limit vibrations and ensure good stability of the device.

Connections, tests, and commissioning

Once the connections are completed, our team performs the necessary checks: tightness, vacuum, electrical connections, communication between units, operation in cooling and heating, drain control, and command validation. Commissioning is never a formality; it confirms that the system works as expected.

Common mistakes to avoid in a DoubleZone project

A multi-zone system can offer excellent performance, but only if it is well designed and well installed. Here are the mistakes we often see when projects are poorly planned.

Choosing the outdoor location based only on appearance

The outdoor unit must be discreet, but above all, it must breathe properly. A device placed too close to an obstacle, too low to the ground, or in a hard-to-reach place can lose efficiency and complicate HVAC maintenance.

Neglecting the length of the piping

Each system has length and elevation limits. These parameters must be respected to maintain good performance. In a two-head installation, this planning becomes even more important.

Improperly distributing capacity between the two zones

A head that is too strong or too weak can cause discomfort. The right sizing depends on the area, but also on insulation, sun exposure, the number of occupants, and the actual use of the room.

Underestimating the importance of the outdoor unit

The outdoor ducts are visible. A neglected finish can harm the appearance of the house. In this project in Delson, the layout was organized in a structured way to integrate the system neatly into the facade.

Forgetting future access for maintenance

A system must be able to be inspected, cleaned, and maintained. The outdoor unit must remain accessible, as well as the main connections.

Performance, comfort, and energy efficiency

The GREE FREE MATCH R32 heat pump operates with inverter technology, meaning the compressor modulates its capacity according to actual demand rather than just running in on-off mode. This modulation contributes to better comfort, more stable temperature, and better-controlled energy consumption.

In a Delson home, this feature is especially useful during transition periods, in spring and fall, when needs vary greatly throughout the day. The system can adjust its operation more gradually, improving comfort without creating abrupt cycles.

In summer, the two indoor units help better distribute cool air and control humidity. In winter, the heat pump can provide efficient heating depending on outdoor conditions and the capacity of the installed model. For many homeowners, this type of system becomes a highly appreciated primary or supplementary solution.

Subsidies and eligibility: a point to check from the start

Subsidy programs, such as those related to energy efficiency, can represent a significant advantage for customers installing an eligible heat pump. Eligibility, however, depends on the exact model, capacity, applicable certifications, and criteria in effect at the time of installation.

At AirGreen, we provide the client with the necessary information for their procedures when the device is eligible: detailed invoice, model identification, technical information, and relevant documentation. For a GREE FREE MATCH R32, it is important that the data is clear to avoid any confusion when submitting an application.

We always recommend verifying the applicable conditions at the time of the project, as amounts, criteria, and administrative requirements may change. Our role is to simplify the process as much as possible by providing compliant installation and complete documentation.

Local expertise serving homeowners in Delson and the South Shore

Delson is one of the areas where residential installations often require adaptation to the existing building. Houses may have brick facades, narrow yards, low windows, side entrances, neighborhood constraints, or more complex duct routes. It is precisely in these types of situations that AirGreen’s experience makes a difference.

We do not treat an HVAC installation as a simple equipment setup. We analyze the house, the structure, the client’s needs, the expected performance, and the final appearance. This approach allows us to deliver reliable, clean, and durable projects.

Our team regularly works in Montreal, Laval, Longueuil, on the North Shore and the South Shore, with a wide variety of configurations: single-family homes, condos, plexes, townhouses, renovated buildings, and properties with architectural constraints. Each project allows us to apply a rigorous method while adapting it to the site’s details.

A clean, efficient result consistent with the facade

The installation of this DoubleZone GREE FREE MATCH R32 heat pump in Delson clearly illustrates the importance of careful work. The outdoor unit is securely installed on wall mounts, clearance is respected, the outdoor routing is organized, and the whole remains functional for future interventions.

For the client, the result translates into more precise comfort in two zones of the house, better temperature management, and a less bulky solution than an installation with two separate outdoor units. For us, this project represents exactly the type of work we love to do: a technical, visible installation that must be both efficient and well integrated.

Choosing AirGreen for a heat pump, a wall air conditioner, a multi-zone installation, or HVAC maintenance means entrusting your project to a team that understands the demands of the Quebec climate, the constraints of local buildings, and the importance of professional finishing. In Delson as elsewhere on the South Shore, we always prioritize a durable, safe installation that is truly adapted to the client’s needs.
