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 compact and clean DoubleZone installation in an interior courtyard in Vaudreuil-Dorion

In Vaudreuil-Dorion, our AirGreen team completed the installation of a DoubleZone GREE FREE MATCH R32 heat pump, configured as 2 zones with 2 wall units, for a client who wanted to improve the comfort of two distinct areas of their home while maintaining a discreet and professional exterior finish.

The project photo clearly shows the particular context of this installation: a GREE outdoor unit positioned in a tight space, near a brick wall, a patio door, and a residential passage. The unit is installed on a metal wall mount, slightly elevated from the ground, which helps protect the unit from snow accumulation, runoff water, and debris. On the right, you can see the ducts protected by brown line covers, perfectly matching the brick and existing exterior elements. This finishing choice reduces the visual impact of the installation while protecting the refrigerant lines, communication cables, and drains.

This project perfectly illustrates the type of HVAC installation where field experience makes all the difference. Installing a multi-zone heat pump in an open, clear, and unconstrained space is one thing. Successfully completing a clean, safe, efficient, and aesthetic installation in an already developed residential environment, with limited maneuvering space, requires more precise planning.

At AirGreen, we regularly work in properties in Montreal, Laval, Longueuil, the North Shore, and the South Shore, but each building has its own particularities. In Vaudreuil-Dorion, this installation required special attention to three elements: the positioning of the outdoor unit, the routing of the lines to the two wall units, and the visual integration of the components on a brick facade.

A GREE FREE MATCH R32 heat pump well suited for multi-zone residential projects

Why a DoubleZone heat pump was the right choice

The client was looking for a solution capable of handling two comfort zones without installing two separate outdoor units. A DoubleZone configuration allows connecting two indoor units to a single outdoor unit, which is particularly advantageous when the available space around the house is limited.

In this residence in Vaudreuil-Dorion, choosing a GREE FREE MATCH R32 DoubleZone heat pump offered several concrete benefits:

  • a single outdoor unit to supply two areas of the house;
  • better temperature control room by room;
  • a reduction in outdoor clutter;
  • a more harmonious installation near a yard, balcony, or passage;
  • better efficiency than an improperly sized or poorly distributed system;
  • a solution suitable for both heating and air conditioning.

For an owner, the difference is mainly felt in daily use. One wall unit can serve a living area, while the other can serve a bedroom, an office, a floor, or a space that is often less comfortable. Rather than trying to push air from a single unit throughout the entire house, the 2 zones and 2 heads configuration allows for a more logical and precise distribution.

The GREE FREE MATCH R32 model: a flexible solution for homes in Vaudreuil-Dorion

The GREE FREE MATCH R32 range is designed for residential multi-zone installations. It allows adapting the system to the real needs of the home, both in terms of capacity and the number of indoor units. In a market like Vaudreuil-Dorion, where there are single-family homes, condos, townhouses, and properties with yard or facade constraints, this flexibility is an important advantage.

The refrigerant R32 is also a notable point. It is a modern refrigerant, used in several recent systems due to its thermal efficiency and generally optimized charge. For owners comparing available heat pump options, choosing an R32 system represents a move towards more current technology, better aligned with the new HVAC market standards.

The system installed in Vaudreuil-Dorion thus combines comfort, efficiency, and adaptation to the building's physical constraints, without multiplying outdoor units.

A strategic outdoor positioning in a confined space

One of the most important aspects of this project was the location of the outdoor unit. In the photo, you can see that the device is installed in a space near a patio door and a brick wall, with a guardrail in the foreground and a traffic area nearby. In this kind of context, several common mistakes must be avoided: placing the unit too close to an obstacle, blocking access to a door, compromising air clearance, or exposing the device to excessive snow accumulation.

Our team therefore chose an installation on a metal wall mount. This method offers several advantages in the Quebec climate:

  • it keeps the outdoor unit above ground level;
  • it reduces the risk of snow accumulation around the base;
  • it facilitates drainage and maintenance;
  • it limits direct contact with water, ice, and debris;
  • it allows a stable installation when the ground or slabs are not ideal.

In areas like Vaudreuil-Dorion, Montreal, Laval, Longueuil, the North Shore and the South Shore, winters impose very concrete constraints on HVAC systems. An outdoor unit installed too low can quickly become surrounded by snow or ice. By raising it properly, its reliability is improved and access for HVAC maintenance is facilitated.

A discreet exterior finish thanks to the brown line covers

A detail visible in the photo deserves special attention: the exterior ducts are protected by brown line covers, which match well with the brick and the existing vertical downspout. This decision may seem simple, but it greatly changes the final appearance of the project.

In a multizone installation, refrigerant lines, communication cables, and drains can quickly become visible if the routing is not well planned. A neglected finish can give the impression of a makeshift installation, even if the machine itself is of good quality. Conversely, well-chosen and well-aligned line covers allow the system to blend into the house's architecture.

In Vaudreuil-Dorion, the brown color helped reduce the contrast with the facade. The vertical lines follow the existing brick structure, giving a more natural finish. For homeowners who care about the exterior appearance of their residence, this type of detail is essential.

At AirGreen, we consider that the finish is an integral part of the quality of a HVAC installation. An installation must work perfectly, but it must also respect the appearance of the property.

The technical challenges of a DoubleZone installation

Installing a DoubleZone heat pump requires more coordination than a simple wall system. With two indoor units, you have to manage two piping routes, two condensation drains, and several communication connections. The outdoor unit must be connected precisely so that each zone functions properly.

In this project, the main constraints were related to the available space and the routing of the lines. The presence of the patio door, the brick wall, the protruding structure, and the passage space forced our team to carefully plan the exits to the outside. The goal was to avoid unnecessary routes, reduce visible lengths, and protect the components from the weather.

The essential steps included:

  1. evaluating the location of the two wall units;
  2. planning the exterior penetrations;
  3. choosing the route for the refrigerant lines;
  4. securely installing the wall mount;
  5. setting up the GREE outdoor unit;
  6. connecting the lines, cables, and drains;
  7. installing the line covers;
  8. complete system verification;
  9. commissioning the two zones;
  10. explaining the operation to the client.

Each step influences the final performance. A poor drain slope, an uneven support, poorly protected lines, or incorrect communication between components can cause problems in the short or medium term. That is why we apply a rigorous method to every project.

The comfort achieved after installation

Once the GREE FREE MATCH R32 is commissioned, the client benefits from better-distributed comfort throughout the house. The two wall units allow managing zones according to their actual use. For example, one zone may be used mainly during the day, while another is more used in the evening or at night.

This flexibility helps avoid several common discomforts in multi-room homes:

  • a main room too cold while the bedrooms remain warm;
  • a floor difficult to air-condition with a single unit;
  • a comfortable open area, but poorly served closed rooms;
  • excessive consumption caused by a device trying to compensate for poor positioning;
  • a stronger dependence on electric auxiliary heating.

With a DoubleZone heat pump, comfort becomes more targeted. The system works according to the needs of each space, which improves the occupants' experience while promoting more efficient energy use.

What homeowners should know before choosing a multi-zone system

A multi-zone system is an excellent option, but it must be well designed. The number of heads should not be chosen at random, and the total capacity of the outdoor unit must be adapted to the spaces to be treated. A sizing error can harm comfort, durability, and efficiency.

Before choosing a DoubleZone heat pump, we recommend that homeowners prepare certain information:

  • the approximate area of the rooms to be air-conditioned and heated;
  • the orientation of the windows;
  • the level of insulation;
  • the ceiling height;
  • the use of the rooms;
  • the desired locations for the wall units;
  • the possible location of the outdoor unit;
  • the approximate distance between the indoor and outdoor units;
  • the presence of a balcony, a narrow yard, or a passage;
  • the aesthetic requirements for line covers.

These details help obtain a more accurate quote and a more reliable recommendation. In some cases, a single wall unit is enough. In others, a DoubleZone configuration becomes clearly more relevant. In Vaudreuil-Dorion, the 2 zones and 2 heads configuration matched well the reality of the house and the client's expectations.

Mistakes to avoid during an outdoor installation

The image of this installation shows a well-positioned and protected outdoor unit. This allows us to address several mistakes we sometimes see in the field.

The first mistake is installing the unit directly on the ground without considering snow accumulation. In Quebec, this decision can cause access, ventilation, and performance problems in winter. Installation on a wall mount or elevated base is often preferable when the context allows.

The second mistake is neglecting the appearance of the external ducts. Exposed or poorly aligned lines can harm the facade's aesthetics and reduce component protection. Line covers are not just decorative; they also protect pipes and cables from UV rays, impacts, snow, and temperature variations.

The third mistake is choosing the location of the outdoor unit solely based on installation ease. A location that is easy for the installer is not always the best for the client. Consider noise, clearance, access for maintenance, water drainage, pedestrian pathways, and overall appearance.

The fourth mistake is forgetting future maintenance. An outdoor unit must remain accessible. If it is stuck behind objects, too close to a wall, or difficult to reach, interventions become more complex.

HVAC maintenance: protecting the performance of the GREE FREE MATCH R32

After installation, HVAC maintenance plays a central role in the system's lifespan and performance. The filters of the wall-mounted heads must be cleaned regularly, especially during periods of heavy use. Indoor units naturally accumulate dust and particles, which can reduce airflow if maintenance is neglected.

The outdoor unit must also remain clear. In a yard or a semi-enclosed space like the one visible in the photo, it is necessary to avoid storing objects too close to the unit. Plants, patio furniture, bins, tools, or snow can reduce air circulation around the heat pump.

For a DoubleZone heat pump, it is important to check both heads, as each zone may have a different use. A head installed in a living area can accumulate more dust than a head installed in a bedroom. Periodic inspection also allows checking the condensation drains, connections, and the general condition of the components.

An AirGreen expertise adapted to the realities of Vaudreuil-Dorion

Vaudreuil-Dorion is an area where residential installations can vary greatly from one house to another. Some properties offer large open facades, while others impose space constraints, neighborhood restrictions, interior yards, or exterior finish requirements. This project clearly illustrates our ability to adapt the installation to the building rather than impose a standard solution.

Our team took into account the available space, the brick wall, the patio door, the circulation around the unit, the aesthetics of the line covers, and protection against winter conditions. The result is a compact, clean, and durable HVAC installation, designed to provide reliable comfort in two zones of the house.

The same level of attention is applied to our projects in Montreal, Laval, Longueuil, on the North Shore and the South Shore. Each installation is different, but our method remains the same: fully understand the building, recommend the right equipment, execute the work precisely, and deliver to the client a functional, clean, and well-explained system.

An installation that combines performance, discretion, and durability

This installation of a GREE FREE MATCH R32 DoubleZone 2-Zones 2-Heads Heat Pump in Vaudreuil-Dorion demonstrates that a multi-zone project can be both efficient and visually discreet. The outdoor unit is well positioned, the lines are protected, the finish blends with the brick, and the system meets the comfort needs of two distinct areas.

For homeowners considering a multi-zone heat pump, this project shows the importance of entrusting the work to a team that masters both the technical part and the building integration. A good machine is not enough. The quality of the installation, the choice of location, the routing of the lines, the exterior finish, and the commissioning determine long-term satisfaction.

At AirGreen, we install HVAC solutions designed for the real life of Quebec homeowners: efficient systems, well placed, well protected, and adapted to the actual constraints of homes in the region.

    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.
