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.

A multizone heat pump precisely installed in a residential area of Duvernay

In Duvernay, a well-established neighborhood of Laval where houses often have varied interior layouts, AirGreen carried out the HVAC installation of a GREE FREE MATCH R32 TripleZone heat pump, consisting of 3 zones and 3 wall heads. This project perfectly illustrates the importance of careful planning when a multizone system must be integrated into an already furnished home, with ceilings, drops, doors, ventilation grilles, and architectural constraints to respect.

The photo of this installation shows one of the GREE wall heads installed above an entry area, on a wide wall drop, just above an interior passage. The location is particularly interesting: the unit is placed very high, in a space where air diffusion had to be carefully planned to avoid dead zones while maintaining a clean and discreet appearance. A ceiling ventilation grille and an existing circular element can also be seen, confirming that the team had to work with several already present components.

In this type of residence, the goal is not just to add a wall air conditioner or a heat pump. It is about creating a coherent system capable of efficiently handling multiple zones without compromising interior aesthetics or complicating future maintenance. This is exactly what a well-sized and well-installed GREE FREE MATCH R32 TripleZone configuration allows.

Why choosing a TripleZone system was relevant in Duvernay

Houses in Duvernay, like many properties in Laval, often have areas that behave differently in terms of temperature. An entryway with a high ceiling, an open living room, a sun-exposed bedroom, a home office, or a warmer floor can quickly create comfort differences. A single wall unit is not always enough to meet these needs, especially when rooms are separated by walls, corridors, or level changes.

A TripleZone heat pump solves this problem by managing three distinct sectors from a single outdoor unit. Each wall-mounted unit can be controlled separately, giving occupants much finer control over daily comfort.

The concrete advantages of a 3 zones – 3 units configuration are numerous:

  • better temperature control room by room;
  • reduction of comfort differences between zones;
  • installation without a central duct network;
  • a single outdoor unit to power multiple units;
  • operation adapted to the actual habits of the occupants;
  • an interesting solution for renovated houses or buildings without existing ducts.

For this project in Duvernay, the GREE FREE MATCH R32 series offered the necessary flexibility to meet these constraints. The BTU capacities of the units are selected according to the thermal loads of each room: area, ceiling height, sun exposure, insulation, windows, air circulation, and actual use of the space. At AirGreen, this sizing is an essential step. A unit that is too large can cause short cycles and uneven comfort, while a unit that is too small may run too long without reaching the desired temperature.

A wall-mounted unit installed above a passage area: a thoughtful technical choice

The unit visible in the photo is installed on an architectural drop, above an interior door and a circulation space. This type of location requires a more rigorous analysis than a fully clear wall. It is necessary to ensure that the blown air can be properly distributed, that the unit remains accessible for filter cleaning, that the ceiling clearance is compliant, and that the ducts can be routed without compromising the interior finish.

In this specific case, the positioning of the wall-mounted unit frees up the main walls of the room while using an already existing architectural volume. This is an approach often sought in residential projects where owners want to preserve the layout, avoid moving furniture, maintain the visual balance of the room, and reduce the impact of the equipment on the decor.

Installing a wall-mounted unit in this location required several checks:

  • maintain sufficient clearance around the device;
  • avoid the airflow being blocked by the drop or side walls;
  • keep practical access to the filters;
  • plan condensate drainage with a reliable slope;
  • maintain a clean finish around the unit;
  • avoid any interference with elements already present on the ceiling.

The result is sober and functional. The device integrates well with the existing structure and remains discreet despite its central position above the entrance.

Challenges specific to a multi-zone installation

Installing a GREE FREE MATCH R32 heat pump in TripleZone version is more complex than a single-zone installation. Three indoor heads mean three routes to plan, three zones to balance, three drains to manage, and full coordination with the outdoor unit. Every detail influences the final performance.

The routing of refrigerant lines

The refrigerant lines must be routed logically, cleanly, and in accordance with the manufacturer's requirements. In a residence in Duvernay, where finished walls and architectural elements sometimes limit options, this step may require more thought than expected. Our team always seeks to reduce unnecessary detours, protect the lines, and preserve the appearance of the house.

Condensate drainage

Each wall-mounted head produces water in cooling mode. Poorly planned drainage can cause leaks, odors, or avoidable future interventions. In a multi-zone installation, each outlet must be analyzed separately. The slope, route, and drainage point must be consistent with the actual configuration of the house.

Coordination between the three zones

A multi-zone system must be balanced. It is not enough to connect three indoor units to one outdoor unit. It is necessary to ensure that each zone responds correctly, that the controls are properly paired, that the capacities are appropriate, and that the operation remains stable according to simultaneous demands.

The interior finishing

The photo demonstrates an important point: a good HVAC installation must be visually clean. In an occupied house, homeowners immediately notice the finishing details. The unit must be straight, well aligned, securely installed, and carefully integrated into the decor. The boxes, passages, and outlets must be done professionally.

GREE FREE MATCH R32: a solution suited for residences in Laval

The GREE FREE MATCH R32 is a multi-zone system designed to offer good residential flexibility. Its main advantage is allowing the use of multiple indoor heads with a single outdoor unit. For homeowners in Laval, Montreal, Longueuil, the Rive Nord, and the Rive Sud, this setup is often more practical than installing several separate systems.

The refrigerant R32 is used in several modern pieces of equipment due to its efficiency and improved environmental profile compared to some older generations of refrigerants. In the Quebec residential context, this type of system can provide both summer air conditioning and heating for much of the year, depending on conditions, sizing, and installed configuration.

For a residence like the one in Duvernay, the strength of the system lies not only in the equipment itself but in its ability to adapt to the rooms. One head can serve a living space, another a bedroom, a third an office or a more difficult-to-condition area. This flexibility makes the system particularly interesting for families, remote workers, and homeowners who want better control without modifying the entire mechanical structure of their home.

What this installation in Duvernay reveals about the quality of a successful HVAC project

The location of wall heads directly influences comfort

A common mistake is choosing the location of a wall head solely based on ease of drilling. This approach may seem practical at the time of installation, but it can reduce comfort for years. A poorly placed head can blow directly on occupants, miss part of the room, be difficult to clean, or generate inefficient cycles.

In this project, the location above a passage area allows for interesting diffusion while using a part of the building that was well suited for integrating the unit. This choice highlights the importance of combining technical vision with practical sense.

Mistakes to Avoid When Installing TripleZone

A 3 zones – 3 heads system must be designed as a whole. The following errors are among the most common:

  • choosing heads without calculating thermal loads;
  • installing units too close to the ceiling or an obstacle;
  • neglecting drain slopes;
  • multiplying duct detours;
  • placing the outdoor unit in a poorly ventilated space;
  • forgetting future access for HVAC maintenance;
  • not testing each zone separately;
  • poorly explaining system use to the client.

At AirGreen, we avoid these problems through a clear method: site analysis, tailored proposal, careful installation, full commissioning, and client explanation. This approach reduces the risk of future issues and improves the overall experience.

Practical tips for properly using a multi-zone heat pump

After installation, daily use also influences performance. A TripleZone GREE FREE MATCH R32 heat pump offers a lot of control, but some simple actions can help get better efficiency.

We especially recommend:

  • regularly clean the filters of the wall units;
  • avoid blocking the airflow with furniture or curtains;
  • keep reasonable temperature settings;
  • avoid extreme and repeated changes;
  • use each zone according to actual occupancy;
  • clear the outdoor unit after snow accumulations;
  • schedule periodic HVAC maintenance.

These habits help the system operate more efficiently and contribute to its durability.

Grants and potential eligibility

High-performance heat pump systems may be eligible for financial aid programs depending on current criteria, the exact model, the installed combination, reference numbers, and the requirements of the applicable program. For a multi-zone system like the GREE FREE MATCH R32, it is important to verify eligibility according to the precise installed configuration.

AirGreen supports its clients by providing the necessary information after the work, including equipment details and the invoice. This thoroughness is especially important for multi-head systems, as combinations can vary from one project to another.

Local expertise in Laval, Montreal, Longueuil, North Shore, and South Shore

AirGreen regularly works in Laval, including Duvernay, Chomedey, Sainte-Dorothée, Vimont, Pont-Viau, and Laval-des-Rapides, as well as in Montreal, Longueuil, on the North Shore and the South Shore. This local experience allows us to understand the realities of buildings in the region: homes with architectural features, condos with restrictions, finished walls, limited outdoor spaces, overheated rooms, difficult-to-temperature floors, and drainage constraints.

In every project, our goal remains the same: to offer a solution that truly fits the building. A heat pump can perform very well on paper, but its efficiency depends on the quality of the installation. The choice of locations, sizing, cleanliness of connections, condensate management, and commissioning make all the difference.

A clean, durable installation tailored to the client’s reality

This installation of a GREE FREE MATCH R32 TripleZone heat pump in Duvernay clearly shows how a multi-zone solution can fit into a home without compromising interior aesthetics. The unit visible in the photo is installed in a technical area, above a passageway, with special attention to alignment, clearance, and finish.

For homeowners comparing different options for a wall air conditioner or a wall heat pump, this project highlights an essential point: price and brand alone are not enough to assess the quality of an installation. You also need to consider the planning, the precision of the work, the contractor’s ability to address building constraints, and the quality of after-installation service.

At AirGreen, we prioritize thoughtful, tailored, and clean installations. A well-installed GREE FREE MATCH R32 TripleZone setup can significantly improve the comfort of a home, especially when each zone has its own needs. In Duvernay and throughout the greater metropolitan area, our team focuses on reliability, comfort, finish, and peace of mind.

    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.
