A neat outdoor installation on a brick wall, designed for durability and technical access
In Duvernay, in the Laval area, our AirGreen team completed the HVAC installation of a GREE FREE MATCH R32 DoubleZone heat pump, a 2-zone system designed to supply two indoor heads from a single outdoor unit. The project stands out for a very neat outdoor wall installation, fixed on metal supports directly to the brick wall, with methodical management of refrigerant connections, wiring, and drainage around a narrow space near the residence entrance.
The photo clearly shows the GREE outdoor unit installed high up, near a brick wall and a downspout. This type of configuration requires precise execution: necessary clearances for unit ventilation must be respected, connections protected, access for HVAC maintenance facilitated, visual nuisances avoided, and snow accumulation during the Quebec winter taken into account. In a residential neighborhood like Duvernay, where houses sometimes have limited side spaces, wall mounting often represents a very advantageous solution.
Why a GREE FREE MATCH R32 DoubleZone for this Duvernay house
The choice of a DoubleZone heat pump here met a very specific need: to improve comfort in two distinct areas of the house without multiplying outdoor units. For several homeowners in Laval, this configuration becomes particularly interesting when rooms do not respond the same way to temperature changes. An upstairs bedroom, an open area on the ground floor, an office, or a rear extension can have very different needs, especially during hot periods or rapid seasonal changes.
The GREE FREE MATCH R32 range allows multiple indoor units to be connected to a single compatible outdoor unit, depending on the chosen combination. In this project, the 2-zone configuration allows the client to better control the temperature room by room, with a more flexible approach than a single-zone wall system.
The system operates with refrigerant R32, a more recent technology than many older refrigerants still present in older installations. For an owner, this means a modern solution, better aligned with the equipment currently available on the residential market. The exact choice of BTU capacity depends on the installed combination, room size, insulation, sunlight, number of occupants, and interior layout. At AirGreen, we always validate these elements before recommending a final configuration.
An outdoor wall mounting adapted to Laval's conditions
One of the most important elements in this installation is the position of the outdoor unit. Rather than placing the heat pump directly on the ground, our team chose a wall-mounted installation. This decision offers several advantages in an area like Duvernay:
- the unit is better protected against snow accumulation;
- floor space remains clear;
- vibrations are better controlled thanks to appropriate mounting;
- access to connections and the service panel remains practical;
- the installation maintains a neat appearance along the exterior wall.
Wall mounting, however, requires special attention. The wall must be able to support the brackets, anchors must be installed precisely, and the unit must be perfectly level. A poorly leveled heat pump can cause drainage problems, noise, or premature wear. In this case, the metal supports visible under the unit provide a stable and clear base, which also facilitates future interventions.
A clean management of refrigerant and electrical lines
In the photo, you can see the insulated refrigerant lines running vertically down to the outdoor unit, as well as an electrical box installed nearby. This detail is important because a heat pump installation is not judged solely by the appearance of the unit. The quality of the connection, line protection, finishing around passages, and electrical compliance all play a crucial role in the system's durability.
In this installation, the lines have been grouped and protected in an orderly manner. Their path follows the brick wall, which limits visual clutter. The outdoor electrical box is positioned accessibly, which is necessary for service and safety operations. This approach reflects an important reality: a successful installation must be clean but also practical for technicians who will need to inspect or maintain the machine in the years to come.
The importance of clearances around the outdoor unit
An outdoor heat pump unit must breathe properly. If it is too close to an obstacle, if the airflow is blocked, or if the heat rejected in cooling mode circulates poorly, performance can decrease. In the case of a multi-zone system like the GREE FREE MATCH R32, this issue is even more important because the outdoor unit must meet the demand of two indoor zones.
Our team therefore analyzed the position of the unit relative to the wall, the entrance, the rainwater downspout, and surrounding elements. The goal was to create a compact installation that respects the natural operation of the machine. Good air circulation contributes to better efficiency, reduced mechanical stress, and more stable comfort for the customer.
An installation that takes Quebec winters into account
In Laval, as in Montreal, Longueuil, on the North Shore and the South Shore, winter imposes real constraints on outdoor HVAC systems. Snow, ice, runoff, and freeze-thaw cycles can affect an installation if it is not well designed.
In this project, the outdoor unit is installed high up, which limits risks related to snow accumulation on the ground. The proximity of the rainwater downspout was also taken into account. When a unit is installed near a drain or gutter, it is important to ensure that water does not flow directly onto the machine or sensitive components. Good planning at this stage prevents problems that may only appear several months after the work.
The two zones: targeted comfort and better energy management
The great strength of a DoubleZone heat pump is to allow better-distributed comfort. In a house, not all rooms behave the same way. Some accumulate heat quickly, others stay cooler, and some are only used at certain times of the day.
With two indoor heads, the customer can adjust comfort according to the actual use of the rooms. This helps avoid overusing a single area to try to compensate for discomfort elsewhere. This more precise management can contribute to a more rational use of the system, especially when occupants adjust temperatures to the home's daily schedule.
Subsidies and eligibility: an essential check
For wall-mounted heat pump or multi-zone systems, eligibility for subsidies depends on the exact combination installed, the outdoor model, indoor units, and applicable certifications. A general mention of brand or series is never enough. For a GREE FREE MATCH R32, the combination number, declared performance, and current program requirements must be validated.
At AirGreen, we guide our clients through this step so they understand which documents to keep after installation, what information may be requested, and why technical validation must happen before the final decision. This rigor prevents unpleasant surprises and allows the owner to make an informed decision.
What this installation shows about the AirGreen approach
This installation in Duvernay clearly illustrates our way of working: we don’t just aim to install a machine but to integrate a complete HVAC solution into an existing building. Every detail matters, from choosing the outdoor location to routing the lines, positioning the indoor units, electrical safety, aesthetics, and ease of maintenance.
A neat solution in a restricted outdoor space
The visible space in the photo is relatively narrow. The unit is near a residential access, with a brick wall on one side and a nearby downspout. In this type of situation, work must be neat, minimize clutter, and avoid creating an obstacle in the passage.
Wall-mounted installation frees up floor space and keeps access around the entrance clearer. It also makes cleaning around the unit easier and reduces the risk of accidental impacts. For townhouses, semi-detached homes, horizontal condominiums, or residences with limited side clearance, this solution can be particularly relevant.
Common mistakes to avoid in a multi-zone installation
A 2-zone HVAC installation requires more planning than a simple system. The most common mistakes are often invisible at the time of the quote but can affect comfort or performance once the system is in operation.
Among the mistakes we systematically avoid:
- choosing capacities based only on area;
- underestimating the length of refrigerant lines;
- placing the outdoor unit too low relative to the snow;
- neglecting clearances around the fan;
- installing indoor units in poorly oriented areas;
- forgetting future access for HVAC maintenance;
- poorly protecting exposed lines;
- do not validate subsidy eligibility before installation.
In this project in Duvernay, planning allowed for a compact, stable, and well-integrated result. The outdoor unit is accessible, connections are grouped, and the whole remains consistent with the house's exterior architecture.
The role of maintenance in long-term performance
Even a well-installed heat pump must be maintained. For a DoubleZone system, maintenance concerns both indoor units and the outdoor unit. Filters must be cleaned regularly, coils must stay clean, drains must be checked, and the outdoor unit must be cleared of leaves, snow, or debris.
Good HVAC maintenance helps maintain airflow, reduce odor risks, preserve system efficiency, and extend component lifespan. We recommend owners not to wait for a problem to appear before having their system inspected. A heat pump used for heating and cooling operates several months a year; regular maintenance therefore makes a real difference.
A customer experience focused on clarity
The client from Duvernay wanted an efficient solution, but also a clean and durable installation. Our role was to translate this need into concrete decisions: location of the outdoor unit, choice of line routing, fixing method, validation of the multi-zone configuration, and explanation of the operation.
We take the time to explain the limits and advantages of each option. For example, an outdoor unit can sometimes be installed on the ground, but in this case, wall mounting offered a better result. Similarly, the positioning of the two indoor heads must be studied to ensure useful air distribution in the served rooms.
Local expertise for Laval, Montreal, and surrounding areas
AirGreen regularly operates in Laval, especially in Duvernay, Chomedey, Sainte-Dorothée, Vimont, Pont-Viau, and Laval-des-Rapides. We also carry out installations in Montreal, Longueuil, on the North Shore and the South Shore. This local experience allows us to better anticipate the typical constraints of buildings in the region: brick walls, limited side spaces, condominium requirements, difficult access, distant electrical panels, complex drainage, or constraints related to the exterior appearance.
Each project requires adaptation. A house in Duvernay is not treated exactly like a condo in Montreal or a residence on the North Shore. Our approach is to offer a realistic, efficient, and clean solution, taking into account the actual building rather than applying a one-size-fits-all method to all clients.
Advice for homeowners considering a GREE FREE MATCH R32
