An HVAC installation in Auteuil where every exterior detail matters
In Auteuil, in the northern sector of Laval, our AirGreen team completed the installation of a GREE FREE MATCH R32 DoubleZone heat pump, configured as 2 zones with 2 indoor units. This type of project is particularly interesting because it addresses a very common reality in homes in the region: the need to cool and heat two distinct spaces without multiplying outdoor units, without overloading the facade, and without compromising energy efficiency.
In this specific case, the GREE outdoor unit was installed in a narrow side area, near a wooden fence. The construction photo clearly shows one of the most important aspects of a good HVAC installation: it is not enough to just place the machine outside and connect the lines. You have to consider service access, air circulation, duct protection, clearance around the unit, rainwater management, electrical safety, and the durability of the installation over several winters.
The GREE FREE MATCH R32 is a highly appreciated multi-zone solution for residential projects where two indoor units need to be connected to a single outdoor unit. In a house in Auteuil, this generally allows for conditioning two different living zones, for example a ground floor and a master bedroom, a living room and an office, or two rooms located at opposite ends of the house. The final configuration always depends on load calculation, building orientation, insulation, window placement, and the occupants' lifestyle.
Why a DoubleZone heat pump is often the right choice in Laval
A DoubleZone heat pump offers a concrete advantage: each zone can be controlled separately. Instead of forcing a single wall unit to condition the entire house unevenly, comfort is distributed where it is actually needed. This approach is especially useful in homes in Laval, Montreal, Longueuil, the North Shore, and the South Shore, where constructions vary greatly from one neighborhood to another.
In Auteuil, there are several types of housing: single-family homes, semi-detached houses, extensions, finished basements, and properties renovated over the years. In this context, a 2-zone system like the GREE FREE MATCH R32 offers a lot of flexibility. One indoor head can serve a main area while the second targets a more difficult zone to balance, such as a sun-exposed bedroom, a space above a garage, or a room far from the heart of the house.
The client thus benefits from three major advantages:
- better temperature control room by room;
- a reduction in comfort differences between zones;
- a single outdoor unit instead of two separate devices.
This logic is at the heart of our approach at AirGreen: to offer a solution that fits the building, not just sell a machine because it is available.
What the photo reveals about the quality of the outdoor installation
The image shows a GREE outdoor unit installed on a solid support, with well-grouped and protected refrigerant lines. An outdoor electrical disconnect box is also visible, an essential element for safety, maintenance, and compliance of a residential installation.
Several details deserve to be highlighted.
First, the unit is not simply placed on the ground. It is elevated, which helps protect it against the accumulation of snow, ice, dead leaves, and splashes from the ground. In Greater Montreal, this precaution is important, especially for heat pumps that also operate in heating mode during cold periods.
Next, the ducts are well grouped in a protective sheath. Refrigerant lines, communication wiring, and associated elements must be protected against UV rays, light impacts, rodents, friction, and damage caused by freeze-thaw cycles. A clean outdoor installation is not only aesthetic: it directly contributes to the system's lifespan.
Finally, positioning near a fence requires special attention. An outdoor unit needs sufficient clearance to breathe properly. Air must be able to circulate around the exchanger without excessive recirculation of hot air in summer or cold air in winter. Our job is therefore to optimize the available space while respecting the technical clearances necessary for the proper functioning of the device.
The GREE FREE MATCH R32: a multi-zone platform adapted to residential needs
The GREE FREE MATCH R32 is designed for multi-zone installations, which means a single outdoor unit can supply several compatible indoor units. In the case of this installation in Auteuil, the chosen configuration is a DoubleZone heat pump - 2 zones - 2 heads.
The refrigerant R32 is now very present in modern residential air conditioning and heating systems. It allows the design of efficient, compact equipment adapted to current expectations regarding energy performance. For the customer, this translates into a high-performance solution, more up-to-date than older generations of systems, and better suited to residential renovations.
The BTU capacities of a FREE MATCH system vary depending on the chosen combination: capacity of the outdoor unit, power of each indoor head, pipe lengths, height between units, potential losses, and the actual needs of the rooms. At AirGreen, we avoid recommending capacity based solely on area. Two rooms of the same size can have very different needs depending on orientation, insulation, number of windows, ceiling height, and daily use.
That is why, before an HVAC installation, we analyze:
- the actual area of each zone;
- sun exposure;
- insulation;
- the possible location of the indoor heads;
- the distance between the heads and the outdoor unit;
- the available electrical panel;
- external constraints such as fences, passages, balconies, terraces, and service entrances.
This planning stage often makes the difference between a heat pump that works properly and an installation that provides stable comfort for many years.
A clean, durable execution designed for maintenance
The main challenge: fitting the machine into a restricted outdoor space
On this site in Auteuil, the most visible challenge was the outdoor space. The presence of the wooden fence, the limited passage around the unit, and the proximity of the connections required a very careful installation. In this type of setup, every inch counts.
A common mistake would be to place the unit too close to an obstacle, which can reduce efficiency, increase the perceived noise level, hinder defrosting in winter, and complicate access during future HVAC maintenance. Our team therefore paid special attention to the position of the unit, the path of the refrigerant lines, and the clearance needed around the service panel.
The outdoor electrical box, visible in the photo, also plays an important role. It allows power to be cut near the unit during maintenance or technical intervention. A clear, accessible, and protected electrical installation is essential for working safely.
Line protection: a detail that influences durability
The refrigerant lines are the vital link between the outdoor unit and the two indoor heads. When they are poorly protected, exposed, or poorly supported, they can wear out prematurely. In a multi-zone installation, the quality of these connections is even more important because a single outdoor unit serves two distinct zones.
In this installation, the lines have been grouped and protected to limit the risk of damage. The goal is simple: to maintain a clean, stable, and reliable installation despite rain, snow, sun, temperature variations, and natural building movements.
At AirGreen, we know that problems do not always come from the machine itself. Very often, issues arise due to poor installation: poorly tightened fittings, poorly insulated lines, inadequate slope, neglected drainage, poorly evaluated pipe length, or poorly adapted outdoor support. It is precisely to avoid these mistakes that we pay so much attention to installation details.
A 2-head configuration for smarter comfort
A heat pump with two heads allows better distribution of heating and cooling in the house. In many projects in Montreal, Laval, Longueuil, on the North Shore and the South Shore, we see clients who initially thought of installing a single wall head, then realize that their house has two very different zones.
For example, an open area can be comfortable with a well-placed head, but a bedroom located on the opposite side can remain too hot in summer. Conversely, a basement may require less cooling but more heating in mid-season. With a DoubleZone solution, it becomes possible to adjust each head according to the actual use of the space.
In this installation in Auteuil, the GREE system allows precisely this separate management. The client can cool one zone without necessarily pushing the other to the same temperature. This flexibility improves comfort and can also reduce consumption when the system is used with discipline.
Mistakes to avoid before installing a DoubleZone heat pump
A multi-zone installation requires more planning than a single-zone system. Here are the mistakes we most often see during replacements or corrections of poorly designed projects:
Choosing capacity only based on the number of square feet
The area is useful, but it is not enough. A very windowed room, exposed to full south or poorly insulated, may require a different capacity than a more closed and shaded room.
Neglecting the placement of indoor units
A poorly placed indoor unit can create drafts, dead zones, or uneven comfort. The positioning must take into account the natural air circulation, furniture, doors, stairs, and daily use.
Underestimating external constraints
A fence, a patio, a narrow passage, a hedge, or a porch can complicate the installation. That is why a technical visit or a careful site analysis is essential.
Forgetting future access for maintenance
A good installation must also be easy to maintain. The filters of the indoor units must be accessible, the outdoor unit must be inspectable, and the connections must remain reachable if intervention is necessary.
Comparing price only
A HVAC installation that is cheaper can become costly if it causes vibrations, leaks, poor performance, or premature wear. The quality of the installation matters as much as the chosen brand.
AirGreen’s experience on multi-zone projects
At AirGreen, we regularly carry out multi-zone installations in very varied contexts: condos in Montreal, single-family homes in Laval, triplexes in Longueuil, residences on the North Shore, renovated properties on the South Shore. Each site has its constraints, and it is precisely this experience that allows us to adapt our methods.
In several recent projects, we had to deal with very tight access, condominiums requiring insurance documents, ducts to be discreetly routed, or electrical panels needing verification before installation. Our role is to anticipate these situations so the client gets a clear, compliant, and durable solution.
For this installation in Auteuil, the exterior finish was an important point. A unit visible near a fence must be installed neatly, with a logical routing of lines and a safe electrical connection. The result is a discreet, solid installation adapted to the immediate environment of the house.
Subsidies, eligibility, and documentation
Eligible heat pumps can sometimes qualify for financial aid programs, depending on current criteria, the exact installed combination, applicable certification, energy efficiency, and program rules at the time of installation. For a multi-zone system like the GREE FREE MATCH R32, eligibility must always be validated according to the precise combination of the outdoor unit and indoor heads.
At AirGreen, we provide the client with the necessary documents after installation, including the detailed invoice, information about the installed equipment, and useful data for subsidy applications when the system qualifies. This step is important because a poorly prepared application can cause delays or refusals.
We always recommend keeping:
- the final paid invoice;
- model numbers of the indoor and outdoor units;
- the serial number;
- AHRI or equivalent information when applicable;
- photos of the installation;
- all documentation provided by the installer.
What the client gains daily
After a well-executed installation, the difference is mainly noticeable in daily use. The client doesn’t just get a new machine: they get a better-balanced home. The two zones can be managed according to the time of day, room occupancy, and seasons.
In summer, the air conditioning becomes more uniform. In mid-season, the heat pump can reduce the need for central heating. In winter, depending on the outdoor temperature and the house layout, it can contribute to comfort while limiting the use of other heating sources.
Another advantage is discretion. A single outdoor unit for two heads helps reduce clutter around the house. In a residential area like Auteuil, where side and back yards may be limited, this aspect matters a lot.
Why entrust this type of project to AirGreen

This installation of a GREE FREE MATCH R32 DoubleZone in Auteuil clearly illustrates our way of working: a serious technical solution, installed cleanly, with particular attention to the building's real constraints. For a homeowner who wants to improve comfort without multiplying outdoor units, this type of system represents a very relevant option.
Practical tips to extend the system's lifespan
After installation, a few simple habits help maintain performance:
- clean the indoor unit filters regularly;
- keep the outdoor unit clear of leaves, branches, snow, and ice;
- avoid blocking air outlets with furniture;
- use stable temperatures rather than extreme adjustments;
- schedule periodic HVAC maintenance;
- monitor any unusual noise or change in performance.
A well-installed and well-maintained heat pump can provide excellent comfort for many years. The key is not to wait for a problem to appear before taking action.
