In summer, the outdoor unit rejects the house's heat outside.

Generic illustration of this type of installation, not a survey of this job site. Tap a number.

  1. 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.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

The job

An HVAC installation in Charlemagne where each comfort zone had to be treated separately

In Charlemagne, on the North Shore of Montreal, our AirGreen team completed a full HVAC installation of a TripleZone heat pump GREE FREE MATCH R32, configured with 3 zones and 3 indoor heads. This type of project addresses a very common reality in homes in the region: heating and cooling needs are never exactly the same from one room to another. An upstairs bedroom, a living room more exposed to the sun, a cooler basement, or an open area with large glazed surfaces each require a different approach.

In this specific case, the choice of a GREE FREE MATCH R32 system was an especially relevant solution because it allows connecting multiple indoor units to a single outdoor unit. The result: better-distributed comfort, a cleaner exterior facade than with several independent condensers, and more flexible temperature control in each living space.

The project photo clearly shows the GREE outdoor unit installed against a brick wall, in an environment where precise positioning was crucial. The available space, proximity to the vertical metal structure, access to the wall, and the clearance required around the unit demanded careful installation. At AirGreen, this type of context is part of our daily work: adapting the heat pump, refrigerant line routing, condensate drainage, and electrical constraints to the building's reality, without improvisation.

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

A TripleZone heat pump is not simply a larger version of a single-zone wall system. It is a more complete HVAC solution that must be sized and installed with a comprehensive view of the building. In Charlemagne, the owners wanted to achieve stable comfort in several rooms without multiplying outdoor units or compromising the building's appearance.

The GREE FREE MATCH R32 system meets this need thanks to a flexible architecture. A single outdoor unit powers three indoor heads, each controllable separately. This configuration offers several concrete advantages:

  • Independent management of 3 zones to avoid overheating or overcooling rarely used rooms.
  • Reduced outdoor footprint, since a single condenser serves multiple spaces.
  • Better usage efficiency when needs vary according to the time of day.
  • Personalized comfort for bedrooms, the living room, the office, or the basement.
  • Cleaner installation from an architectural standpoint, especially in residential neighborhoods of the North Shore.

In a house where occupants do not use all rooms at the same time, this flexibility becomes very interesting. For example, a bedroom can be kept cooler at night, while the living room can remain comfortable in the evening, without having to impose the same temperature throughout the house.

The GREE FREE MATCH R32 model: a multi-zone platform designed for flexibility

The GREE FREE MATCH R32 series is appreciated for multi-zone projects because it allows adapting the system to the real needs of each building. Unlike a central unit that treats the entire house more uniformly, a multi-zone wall solution provides room-by-room control.

In this installation in Charlemagne, the 3 zones – 3 heads configuration allowed coverage of priority spaces while limiting intervention on the building envelope. The refrigerant R32 is also an important point. Used in several new generations of HVAC systems, it enables the design of efficient equipment while meeting current market requirements for efficiency and reducing environmental impact compared to older refrigerants.

The exact performance of a multi-zone system always depends on the chosen combination: capacity of the outdoor unit, capacity of each indoor head, pipe lengths, elevation difference, installation conditions, and overall certification. For this reason, at AirGreen, we validate each configuration according to the building's thermal needs and applicable technical data before recommending a final combination.

Subsidy eligibility to be validated according to the exact configuration

For clients in Montreal, Laval, Longueuil, the North Shore, and the South Shore, the question of subsidies comes up very often. A multizone heat pump can, depending on the exact model, the indoor/outdoor combination, official lists, and the rules in effect at the time of the project, be eligible for certain aid programs.

In the case of a system like the GREE FREE MATCH R32, we always recommend validating eligibility based on the exact installed combination. Multizone systems must be carefully checked because eligibility does not depend only on the series name: it also depends on model numbers, applicable certification, installed capacity, and the current program requirements. A common mistake we see with some clients before their call to AirGreen is assuming a model is eligible without verifying the complete combination.

Our role is to guide the client with the right information, provide a clear invoice, and deliver the necessary documents to facilitate post-installation procedures.

The technical challenges of this installation in Charlemagne

The success of a multizone HVAC installation rarely depends on a single element. It rather depends on a series of well-executed technical decisions: location of the outdoor unit, routing of refrigerant lines, clearances, drainage, electrical supply, duct protection, noise level, access for HVAC maintenance, and visual integration.

In the photo, the GREE outdoor unit is installed near a brick wall, with a vertical metal structure nearby. This type of environment requires special attention because the unit needs to breathe properly. A poorly positioned condenser, too close to an obstacle or installed without respecting the recommended clearances, risks losing efficiency, overworking unnecessarily, or becoming harder to maintain.

Positioning the outdoor unit without compromising performance

The first challenge was to choose a stable and functional location for the outdoor unit. For a TripleZone heat pump, this point is even more important than for a simple wall system, as the outdoor unit serves three indoor zones. It must therefore be installed to ensure good air circulation, safe access for technicians, and adequate protection against snow, water, or debris accumulation.

In Charlemagne, the brick wall offered a visually clean and durable surface, but the installation had to be treated as more than just a mechanical addition. Our technicians took into account:

  • clearance around the fan;
  • access to the service valves;
  • the possible routing of the refrigerant lines;
  • the presence of the metal structure;
  • the stability of the location;
  • the final aesthetics;
  • the future needs of HVAC maintenance.

A clean installation is not limited to what is seen on the day of the work. It must also remain practical in five, eight, or ten years when maintenance, inspection, or repair becomes necessary.

Three indoor heads, three different realities

In a 3-head configuration, each indoor unit must be placed according to the logic of the room. A head installed too close to an obstacle, too high without good diffusion, or directly aimed at a resting area can create discomfort despite a quality device. That is why we always assess air circulation, available height, furniture layout, sun exposure, and occupant habits.

For this installation in Charlemagne, the goal was to achieve balanced comfort in the three zones without visually overloading the rooms. A good multizone system must be discreet but effective. The wall heads must be well placed enough to distribute air without forcing, while allowing reasonable access to the filters for regular maintenance.

The importance of refrigerant line routing

A GREE FREE MATCH R32 multizone system involves several refrigerant lines connecting the outdoor unit to the indoor heads. The routing of these lines is one of the most important aspects of the project. It is necessary to minimize unnecessary lengths, respect technical limits, protect the ducts, ensure a proper slope when needed, and avoid poorly positioned penetrations.

In a residential project on the North Shore, the constraints are not only mechanical. There is also the exterior appearance, condominium regulations when applicable, owner preferences, wall access, interior finishing, and weather protection. At AirGreen, we plan the process before starting drilling, because a bad decision at this stage can lead to costly complications.

A clean installation on a brick wall: precision, anchoring, and finishing

The brick wall visible in the photo gives a good overview of the reality of the site. Brick is a durable material, but it requires an appropriate fastening method. Drilling into masonry without preparation can cause chipping, weak anchors, or leaks if openings are not properly treated.

Our technicians paid special attention to the quality of anchors, protection of passages, and finishing. On an outdoor installation, the small details make a big difference: a well-sealed passage, a well-aligned line, a well-protected outlet, and a stable device provide a lasting result.

For a HVAC installation in Montreal, Laval, Longueuil, on the North Shore or the South Shore, these same principles apply. Buildings change, but quality requirements remain the same.

Common mistakes to avoid with a multi-zone heat pump

A TripleZone heat pump can offer excellent comfort, but only if it is well designed. Several mistakes often recur when owners compare options or receive quotes too quickly.

Here are the most common ones:

  1. Choosing capacity based only on total area
    A house of the same size can have very different needs depending on insulation, orientation, windows, floor, and room usage.
  2. Installing heads in the wrong places
    A poorly placed head can create cold spots, drafts, or uneven temperature.
  3. Neglecting pipe lengths
    A route that is too long or poorly planned can reduce performance and complicate maintenance.
  4. Underestimating the importance of drainage
    Condensate drainage must be carefully planned, especially when heads are installed in distant zones or at different heights.
  5. Comparing only the final price
    A cheaper installation can hide compromises on materials, finish, positioning, or the time spent on commissioning.
  6. Forgetting future maintenance
    Filters, valve access, space around the condenser, and service points must be accessible.

At AirGreen, we often see clients who contact us after receiving an inaccurate quote. Our approach is different: we take the time to explain the configuration, constraints, advantages, and limits of the proposed system.

What owners gained with this installation

After commissioning the GREE FREE MATCH R32 system, owners gained more precise control over their comfort. Instead of relying on a single temperature point or a single device placed in a central zone, they can now adjust each space according to the actual use of the house.

The living room can be efficiently cooled during hot days. A bedroom can stay comfortable at night without cooling the entire house. Another zone can be used only when needed. This is exactly what makes a TripleZone heat pump interesting: it respects the occupants' lifestyle.

From the outside, installing a single GREE unit for three zones also helps preserve the building's appearance. On a property in Charlemagne, as elsewhere on the North Shore, owners often want to improve their comfort without changing the facade or cluttering the yard with multiple devices.

Why AirGreen is often chosen for multizone installations

Multizone projects require more than just equipment installation. They demand a true understanding of the building, the thermal behavior of the rooms, and installation standards. AirGreen regularly works on projects involving heat pumps, wall air conditioners, multizone systems, and HVAC maintenance in Greater Montreal.

Our experience covers very varied contexts: single-family homes in Laval, duplexes in Montréal, condos in Longueuil, properties on the South Shore, older homes on the North Shore, commercial spaces, offices, mechanical rooms, and installations where exterior aesthetics must be particularly refined.

This experience allows us to anticipate issues before they become problems. In a project like the one in Charlemagne, we do not just install a device. We validate the entire project: capacity choice, head placement, duct routing, outdoor positioning, condensate drainage, electrical supply, operation tests, and explanations to the client.

Practical advice before installing a GREE FREE MATCH R32 TripleZone

Before choosing a GREE FREE MATCH R32 TripleZone heat pump, some checks are essential.

Clearly identify priority zones

It is not always necessary to treat all rooms in the house. Instead, focus on areas where comfort has the most impact: main bedrooms, living room, open area, home office, or regularly used basement.

Assess insulation and sun exposure

A room with many windows or facing due south may require more cooling capacity. A north-facing bedroom can behave very differently in winter. These details influence the choice of heads and their placement.

Plan the line routing before choosing locations

The best indoor locations must be compatible with a clean and technically feasible outdoor route. A nice wall head poorly connected can result in lines that are too long or a less elegant exterior finish.

Consider maintenance from the start

A successful installation must allow for regular filter cleaning and easy access to service components. HVAC maintenance extends the system's lifespan and maintains its performance.

A representative project of HVAC needs on the North Shore

This installation of a TripleZone GREE FREE MATCH R32 heat pump in Charlemagne perfectly illustrates the current demands of Greater Montreal homeowners. Clients are looking for efficient, flexible, relatively discreet systems adapted to Quebec winters as well as intense heat periods.

In Montreal, Laval, Longueuil, on the North Shore and the South Shore, multi-zone solutions are gaining popularity because they address a simple reality: a house is not a single uniform space. Each room has its needs, constraints, and usage times.

At AirGreen, we approach every project with this mindset. The choice of equipment matters, but the quality of the installation matters just as much. A well-sized, well-installed, and well-explained GREE FREE MATCH R32 can transform the daily comfort of a home while providing a clear, durable, and building-adapted solution.

Conclusion: a well-thought-out 3-zone installation for lasting comfort in Charlemagne

This project in Charlemagne demonstrates the full value of a rigorously executed HVAC multi-zone installation. The TripleZone GREE FREE MATCH R32 heat pump, with its 3 indoor units, offers occupants precise control, better comfort distribution, and a more discreet outdoor integration than multiple separate units.

The outdoor unit installed against the brick wall, visible in the photo, perfectly sums up our approach: a clean, structured installation, adapted to the building's constraints and designed for the long term. For homeowners considering a heat pump in Charlemagne, in Laval, in Montreal, in Longueuil, on the North Shore or the South Shore, this project is an excellent example of what a well-planned multi-zone solution can bring to residential comfort.

    Frequently asked questions

    What people ask us about this kind of work

    12 questions
    Does a wall-mounted heat pump heat in winter?
    Yes, it heats and cools. Its capacity drops in very cold weather; the operating range depends on the model and is listed on its spec sheet.
    Wall-mounted or multi-zone: how do I choose?
    One wall head and one condenser outside: the direct solution for a room or an open area. For two to five rooms, a multi-zone puts one head in each room on a single condenser.
    Where does the outdoor unit go?
    Where it stays above the snow, clear and accessible, away from walkways. We decide it with you during the estimate.
    Are there grants?
    Depending on the model and your situation, assistance programs may apply, including Hydro-Québec's LogisVert. AirGreen checks the model number before quoting an amount. See the grants.
    Do I need a permit?
    Rules vary from city to city: location, distances, noise. See permits and by-laws, and we check for your address.
    How cold can it heat?
    It depends on the model. According to Hydro-Québec, newer models work down to a temperature between −15 °C and −25 °C, and some cold-climate models are certified lower. The minimum temperature is on each unit's spec sheet.
    How much can I save?
    Hydro-Québec says a heat pump can be up to three times more efficient than baseboards for heating in the colder months. The result depends on the house, the climate and how it is used.
    How is the LogisVert assistance calculated?
    For ENERGY STAR cold-climate certified heat pumps, Hydro-Québec lists assistance of $120 per 1,000 BTU/h of heating capacity at −8 °C. AirGreen checks the exact model before quoting an amount; only Hydro-Québec confirms the assistance granted. See the grants.
    Is it noisy?
    The sound level depends on the model and is listed in decibels on each unit's spec sheet. Location matters too: when possible, we avoid putting the outdoor unit under a bedroom window.
    The outdoor unit is covered in ice: is that normal?
    Some frost is: the unit runs defrost cycles. Never hit the ice. If the unit stays iced up or stops heating, call us.
    Does AirGreen hold the required licences?
    Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
