An installation in Auteuil where the precision of the outdoor assembly made all the difference
In Auteuil, in the northern sector of Laval, our AirGreen team completed the installation of a DoubleZone GREE FREE MATCH R32 heat pump, configured in 2 zones with 2 indoor wall units. This project very well represents the type of residential installation that requires a serious technical approach: limited outdoor space, brick facade, presence of elements already installed on the wall, need for a solid support, well-organized duct routing, and particular attention to the final aesthetics.
In the project photo, the GREE outdoor unit is clearly visible, mounted on metal wall brackets, directly in front of a brick facade. To the right of the device, a vertical brown cover protects and conceals the passage of refrigerant and electrical lines. This finish is particularly important in a visible installation because it prevents the impression of a system added in an improvised way. The device is well aligned, the supports are installed neatly, the connections are grouped, and the whole remains accessible for future HVAC maintenance.
In this type of project, the difficulty is not only in installing the equipment. It is also necessary to understand how the heat pump will integrate with the building, how the two indoor zones will be supplied, where to route the ducts without harming the appearance of the facade, how to maintain good clearance around the outdoor unit, and how to avoid unwanted vibrations transmitted to the wall.
In Auteuil, as in several residential neighborhoods of Laval, houses often feature brick facades, narrow side yards, existing equipment near walls, downspouts, panels, windows, or landscaping to work around. A multi-zone installation then requires more than just a simple choice of device: it demands careful planning and clean execution.
Why a GREE FREE MATCH R32 DoubleZone heat pump was suitable for this residence
Choosing a DoubleZone heat pump is often ideal when an owner wants to improve the comfort of two specific areas of their home without installing two separate outdoor units. In this installation in Auteuil, the 2 zones – 2 units configuration allows powering two indoor units with a single outdoor GREE FREE MATCH R32 unit.
This solution is particularly interesting when the rooms to be treated do not communicate perfectly with each other. A single wall unit can sometimes be enough in a large open space, but it quickly reaches its limits when the house has separate bedrooms, a distinct floor, a finished basement, a closed office, or a living area far from the air outlet. With two units, comfort becomes more precise and flexible.
The customer benefits notably from:
- two independently controlled zones;
- better air conditioning distribution in summer;
- effective heating support during cold periods;
- a single outdoor unit instead of two devices;
- an installation better integrated into the facade;
- better adaptation to lifestyle habits;
- a solution compatible with homes without central ducts.
The GREE FREE MATCH R32 series is designed for this type of multi-zone application. It allows multiple indoor units to be connected to one outdoor unit, according to allowable combinations and required capacities. For a residence in Laval, this kind of system often represents an excellent compromise between performance, cost, comfort, and architectural integration.
The importance of the R32 refrigerant in new HVAC installations
The installed model uses the refrigerant R32, which is now very common in the new generations of heat pumps and wall air conditioners. This refrigerant is known for its good energy efficiency and its reduced environmental impact compared to some older refrigerants still on the market.
For an owner comparing several options for air conditioning and heating in the Montreal, Laval, Longueuil area, on the North Shore or on the South Shore, the type of refrigerant may seem like a technical detail. Yet, it directly influences the system design, its efficiency, market compliance, and long-term relevance.
At AirGreen, we place great importance on these elements because a HVAC installation must not only meet immediate needs. It must also be consistent with current standards and suitable for sustainable use.
A wall installation on brick: stability, alignment, and vibration reduction
In the photo, the outdoor unit is installed on a wall mount fixed to the brick. This method has several advantages when done correctly. It keeps the device off the ground, reduces risks related to snow accumulation, frees up floor space, and protects the unit from debris or accidental contact.
However, a wall installation requires great precision. The brick must be used with the correct fasteners, the supports must be perfectly aligned, and the device must be installed stably to avoid vibrations. A poorly fixed support can create noise, weaken the installation, or transmit vibrations to the house structure.
In this project in Auteuil, the supports were positioned to provide a solid base for the outdoor unit. The device is installed at a functional height, with possible access for inspections, cleanings, and future interventions. The clearance around the machine was also considered to ensure adequate air circulation.
An outdoor heat pump needs enough space to draw in and expel air. If it is placed too close to an obstacle, in a poorly ventilated corner, or in a cluttered area, its performance can decrease. The positioning shown here allows for efficient operation while respecting the site constraints.
A brown vertical cover for a cleaner, better-integrated finish
One of the most interesting elements of this installation is the brown vertical cover installed to the right of the unit. On a brick facade, refrigerant and electrical ducts can quickly become very visible if their routing is not well planned. In this project, using a cover color-matched to the building tones protects the lines while improving the overall appearance.
This finish has several advantages:
- it protects the lines against weather conditions;
- it reduces exposure to sun, rain, and snow;
- it gives a neater appearance to the facade;
- it facilitates the visual integration of the installation;
- it limits the risk of mechanical damage;
- it allows the ducts to be grouped in a clear way.
In a DoubleZone installation, line routing is even more important, as each indoor unit must be connected to the outdoor unit. Proper grouping of the ducts helps avoid a scattered or disorganized result. This highlights the importance of entrusting the work to a team that understands both the technical requirements and the visual impact of an outdoor installation.
Managing constraints around the outdoor unit
The photo also shows the presence of other elements near the wall: a panel or existing box on the left, low ducts at ground level, a restricted workspace, and storage or protective elements in the yard. In a real context, installations almost never take place on a blank, perfect facade. Our technicians have to work with what already exists.
In Auteuil, the outdoor unit had to be positioned without interfering with existing equipment, while maintaining a logical line path and good accessibility. This step requires experience, as a poor choice of location can complicate future maintenance or create conflicts with other building components.
Before installation, several elements must be checked:
- the strength of the wall;
- the available space around the unit;
- the possible passage of refrigerant lines;
- the distance to the two indoor units;
- the location of the power supply;
- condensate management;
- access for future service;
- vibration reduction;
- the final appearance of the facade.
These details are essential to achieve a reliable, durable, and visually pleasing HVAC installation.
An AirGreen project that shows the importance of a well-planned multi-zone installation
Two zones, two needs, one outdoor unit
The main advantage of a DoubleZone heat pump is the ability to adapt comfort to two different spaces. In a home, not all rooms respond the same way to temperature changes. A very sunny room can overheat in summer, while another more shaded space may stay cooler. A bedroom may require a different setting than the living room. A home office may need stable comfort during the day, while a bedroom is mostly used in the evening.
With a GREE FREE MATCH R32 2-head system, the customer can adjust each zone according to their needs. This flexibility improves daily comfort and also helps avoid unnecessarily air conditioning or heating a rarely used zone.
This approach is very relevant in Laval, where many existing homes were not designed with a modern central system. The multi-zone wall-mounted heat pump significantly improves comfort without opening walls to install ducts.
Common mistakes to avoid in a DoubleZone installation
A multi-zone installation is more complex than a single-zone system. Here are some mistakes we always try to avoid at AirGreen.
Incorrectly sizing the indoor heads
It is not enough to simply choose two identical heads by default. Each zone must be evaluated based on its size, insulation, sun exposure, ceiling height, number of windows, and actual use of the room. An oversized head can cause short cycling and reduce comfort. An undersized head may run too long without reaching the desired temperature.
Installing the outdoor unit in a space that is too tight
Clearance around the unit is essential. A poorly ventilated outdoor unit can lose efficiency, consume more energy, and suffer premature wear.
Neglecting the appearance of the ducts
On a brick facade, poorly placed lines are immediately noticeable. A well-chosen cover, a straight path, and a neat grouping of ducts make a big difference.
Forgetting the drainage of indoor units
Each head produces condensation in cooling mode. Drainage must be planned to avoid leaks, odors, backflows, or water accumulation.
Compare only the price of the bids
Two installations can use the same device, but the final quality can be completely different. The supports, fastenings, materials, line routing, insulation, commissioning, and exterior finishing strongly influence the system's durability.
A clean installation facilitates HVAC maintenance
A well-installed system is also easier to maintain. The outdoor unit must remain accessible for coil cleaning, connection inspection, electrical testing, and operation checks. The ducts must be protected but not installed in a way that makes any intervention complicated.
In this project in Auteuil, the wall installation keeps clear access to the device. The vertical cover organizes the line routing, and the unit remains sufficiently clear to allow future interventions. This approach is essential to preserve system performance year after year.
Regular HVAC maintenance helps maintain good efficiency, reduce the risk of breakdowns, and extend the lifespan of the heat pump. This includes cleaning the indoor head filters, inspecting the outdoor unit, checking the drains, verifying heating and cooling operation, and observing signs of vibration or unusual noise.
Grants: check the exact model and installed combination
When it comes to heat pumps in Quebec, many customers want to know if their system may be eligible for financial assistance, especially under programs related to energy efficiency. For multi-zone systems like the GREE FREE MATCH R32, it is essential to verify the exact combination between the outdoor unit and the installed indoor heads.
Eligibility may depend on several factors:
- the exact model numbers;
- the certified performance;
- the system configuration;
- the capacity of the heads;
- the criteria in effect at the time of installation;
- the documents provided with the invoice.
At AirGreen, we help our clients better understand the necessary information for their procedures. We provide a detailed invoice and useful technical information so that the client can submit their request with the correct data. For homeowners in Laval, Montreal, Longueuil, the North Shore, or the South Shore, this support greatly simplifies the process.
Why AirGreen is a strategic choice for multizone projects in Laval
Multizone installations require precise knowledge of the units, but also a good understanding of the building. In Auteuil, our team had to integrate a large outdoor unit on an existing facade, protect the lines, manage constraints around the wall, install a stable support, and ensure the proper connection of two indoor zones.
This type of project is part of our daily expertise. We regularly work on:
- single-family homes in Laval;
- condos in Montreal;
- multizone projects on the North Shore;
- brick installations in Longueuil;
- wall and multizone systems on the South Shore;
- replacements of old units;
- installations with long refrigerant lines;
- configurations where the exterior appearance is a priority.
Our approach is simple: choose the right solution, respect the building structure, install cleanly, and ensure the system works properly before the end of the work. This rigor ensures a reliable installation, but also a visual result that better integrates with the home.
Practical advice for Auteuil homeowners considering a DoubleZone heat pump
Before requesting a quote for a GREE FREE MATCH R32 DoubleZone heat pump, it is helpful to prepare some information. This allows for a better assessment of the project and a more realistic estimate.
Here are the points to consider:
- which two rooms or zones are to be air-conditioned and heated;
- where the wall units could be installed;
- if the outdoor unit can be installed on a wall, on the ground, or on another support;
- if the facade is visible and requires a more discreet finish;
- if the lines must run vertically or horizontally;
- if natural drainage is possible;
- if the electrical panel is accessible;
- if a subsidy application is planned;
- if the house has particular constraints such as fragile brick, a narrow side space, or equipment already present on the wall.
A good assessment from the start avoids surprises at installation time. It also allows choosing the best configuration, both technically and aesthetically.
