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.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
A robust and carefully executed outdoor installation for a multi-zone heat pump designed for Repentigny's climate
In Repentigny, on Montreal's North Shore, our AirGreen team installed a GREE FREE MATCH R32 DoubleZone heat pump, a 2-zone, 2-head system designed to provide precise comfort in two distinct areas of the residence. This type of configuration is particularly relevant when occupants want to air condition and heat two rooms or two levels efficiently, without multiplying outdoor units.
The photo taken at the end of the work shows an essential element of this installation: the GREE outdoor unit installed on a raised structure, well clear of the ground, with a clean routing of the refrigerant and electrical lines. In a region like Repentigny, where snow accumulation, frost, thaw cycles, and winter winds can complicate the operation of poorly positioned HVAC equipment, the choice of location and installation base is as important as the choice of the machine itself.
For this project, the client was looking for a reliable, high-performance, and discreet solution to improve the comfort of the home, while limiting outdoor clutter. The GREE FREE MATCH R32 met this need well: a single outdoor unit, two indoor heads, an inverter modulation adapted to the actual needs of the rooms, and a multi-zone design that allows separate temperature adjustment according to the use of each space.

Why the GREE FREE MATCH R32 system was well suited for this Repentigny residence
The GREE FREE MATCH R32 system is often chosen for residential projects where efficiency, flexibility, and zone-based comfort are desired. Unlike a simple single-head wall-mounted installation, a DoubleZone heat pump can serve two spaces from a single outdoor unit. This approach is highly valued in homes on the North Shore, particularly in Repentigny, Terrebonne, Mascouche, Lavaltrie, and Charlemagne, where building configurations vary greatly: semi-detached, multi-story homes, condos with limited outdoor access, rear extensions, finished basements, and open-plan spaces.
In this specific case, the chosen solution met several needs simultaneously:
- improving comfort in two living zones;
- avoiding the installation of two separate outdoor units;
- reducing visual impact around the property;
- optimizing the use of outdoor space near the fence;
- providing efficient heating in mid-season and stable cooling in summer;
- allowing independent temperature management in each serviced room.
The R32 refrigerant is also an important selling point. It is increasingly used in new generations of residential HVAC systems, partly because it provides good thermodynamic performance with a lower global warming potential than some older refrigerants. For an owner comparing different wall-mounted heat pump or multi-zone system options in Repentigny, this technical detail often becomes a decision-making criterion.
A raised outdoor installation to better manage the Quebec winter
One of the most important elements visible in the photo is the base of the outdoor unit. The equipment rests on a raised structure, supported by blocks and treated wooden parts, which keeps the heat pump at a safer height from the ground.
This point is fundamental for a durable HVAC installation in Quebec. An outdoor unit placed too low can quickly become vulnerable to several problems:
- snow accumulation against the outdoor coil;
- fan obstruction;
- ice formation around the base;
- poor drainage of defrost water;
- vibration transmitted to the ground or structure;
- difficulty of access for HVAC maintenance.
In Repentigny, winters can create demanding conditions for a heat pump. During defrost cycles, the appliance expels water which can then freeze if the base is poorly designed. This is why our team pays particular attention to the height, clearance, orientation, and accessibility of each outdoor unit.
In this project, the installation was carried out in a restricted space, near a fence and an outdoor passageway. It was therefore necessary to find the right balance: close enough to the house to limit unnecessary lengths of conduits, clear enough to ensure air circulation, and stable enough to support the appliance over several seasons.
Clean management of refrigerant and electrical lines
In the photo, we also notice the routing of the lines originating from the outdoor unit. For a DoubleZone heat pump, this step requires more planning than a single-zone system, as two circuits must be connected to the two indoor heads. Each connection must be protected, insulated, correctly oriented, and installed in a way that limits mechanical stress.
At AirGreen, we pay particular attention to these details because they have a direct impact on the performance and longevity of the system. A poorly protected, badly bent, or stressed line can cause problems in the medium term. Insufficient insulation can lead to efficiency losses, condensation, or premature degradation of materials.
In this installation in Repentigny, our team worked to ensure:
- clean routing of refrigerant lines;
- adequate protection of cables and conduits;
- stable fastening;
- a bending radius compliant with installation standards;
- a layout allowing future access for maintenance;
- acceptable visual integration into the outdoor environment.
This type of care is not always visible at first glance, but it distinguishes a professional installation from a merely functional one. For a GREE FREE MATCH R32 heat pump, as for any multi-zone system, the quality of installation plays a major role in the actual performance of the unit.
Two zones, two needs, one well-configured system
The main advantage of a 2-zone, 2-head system is the ability to manage two spaces independently. In a house, comfort needs often vary from one room to another. A sun-exposed living room does not react like a bedroom located at the back. An upper floor can accumulate heat more easily in summer. A basement, on the other hand, may require different heating or dehumidification.
The GREE FREE MATCH R32 allows for configuration adaptation according to these realities. The outdoor unit powers two indoor units, each controlled separately. The client can therefore adjust the temperature according to room occupancy, time of day, and season.
This zone-based comfort is one of the main reasons why we often recommend multi-zone systems to our customers in Montreal, Laval, Longueuil, on the North Shore, and on the South Shore. The goal is not just to install a machine; it's about offering a solution consistent with how occupants actually live in their home.
Technical checks before commissioning
Once the outdoor unit is installed and the indoor heads are connected, our team performs a series of checks before commissioning. This step is essential to ensure the reliability of the system and avoid problems that can arise when a device is started too quickly, without complete validation.
As part of this installation in Repentigny, our technicians paid particular attention to:
- the sealing of refrigerant connections;
- the conformity of electrical connections;
- the stability of the outdoor base;
- the clearance around the unit;
- the quality of condensate drainage;
- communication between the outdoor unit and the indoor heads;
- the proper functioning of heating and cooling modes;
- the response of remotes and sensors.
On a DoubleZone system, communication between components is particularly important. A mismatch between refrigerant lines and electrical connections can lead to malfunctions. This is a common error in less rigorous installations. At AirGreen, each circuit is thoroughly validated so that each indoor head corresponds correctly to its outdoor port.
Subsidies and eligibility: necessary validation based on the exact combination
Many clients who contact us for a heat pump also want to know about eligibility for subsidy programs, especially provincial energy efficiency aids. For multi-zone systems like the GREE FREE MATCH R32, eligibility generally depends on the exact combination installed: outdoor unit, indoor heads, total capacity, certification, AHRI number, and the criteria of the program in effect at the time of the project.
For this reason, we always validate technical information before confirming the potential amount of financial assistance. This step avoids unpleasant surprises. Two systems with a similar commercial name may have different combinations, and thus different eligibility.
Our approach is simple: before presenting a final offer, we check the relevant data and clearly explain to the client what is included, what needs to be confirmed, and what documents will be necessary after installation. This transparency is particularly appreciated by homeowners in Repentigny and neighboring municipalities, where many clients compare models based on the net cost after subsidy.
Mistakes to avoid during a DoubleZone installation
A DoubleZone heat pump offers many advantages, but it must be well designed from the start. The most common mistakes we observe in the field rarely concern the brand of the appliance. They rather concern design, location, and execution.
Here are the most important mistakes to avoid:
Installing the outdoor unit too close to the ground
A base that is too low increases the risk of snow and ice accumulation and obstruction. In a climate like Repentigny's, this error can impair heating performance and complicate maintenance.
Neglecting clearances around the unit
A heat pump needs to breathe. If the unit is too close to a wall, a fence, or an obstacle, air circulation can be reduced. This can affect efficiency and increase compressor effort.
Underestimating the length of the conduits
A 2-head system requires precise planning of routes. Conduits that are too long, poorly insulated, or badly positioned can reduce performance and make the installation less aesthetic.
Choosing heads without analyzing the rooms
The capacity of the indoor heads must match the actual needs of each zone. It is not enough to choose two identical units. Sun exposure, insulation, ceiling height, openings, and room usage must be taken into account.
Forgetting future access for maintenance
An appliance must remain accessible. An installation that is too tight can make future interventions longer and more costly.
A realization that reflects the AirGreen method
This installation in Repentigny perfectly illustrates our way of working. We do not limit our role to simply installing equipment. We analyze the location, building constraints, client expectations, technical feasibility, and the durability of the installation.
For this project, the outdoor environment required special attention: limited space, proximity to the fence, need for a stable base, clean management of conduits, and protection of the equipment against winter conditions. Our team therefore opted for a raised, well-positioned installation, with particular attention to the routing of connections and accessibility.
The result is a functional, solid installation adapted to the reality of a Repentigny residence. The client benefits from a GREE FREE MATCH R32 system capable of serving two distinct zones, with a single outdoor unit, better indoor comfort management, and a well-thought-out exterior integration.
Why Repentigny homeowners choose AirGreen for their HVAC installation
Repentigny clients often contact us after comparing several wall-mounted air conditioner, wall-mounted heat pump, or multi-zone system options. Their primary concern is rarely limited to price. They want to know if the unit will be properly sized, if the installation will be clean, if the team understands Quebec's constraints, if subsidies are clearly explained, and if post-installation service will be available.
At AirGreen, we rely on a comprehensive approach:
- analysis of the building and actual needs;
- recommendations adapted to the client's budget and priorities;
- installation by qualified technicians;
- adherence to best practices in refrigeration and electricity;
- clear explanation of available options;
- support for subsidy-related documents;
- accessible after-sales service;
- installations carried out in Montreal, Laval, Longueuil, on the North Shore, and the South Shore.
Each project is different. A house in Repentigny does not necessarily have the same constraints as a condo in Laval, a duplex in Montreal, or a property on the South Shore. That's why we adapt our recommendations to each situation, rather than automatically suggesting the same system to all clients.
Lasting comfort thanks to a well-designed installation
The performance of a heat pump depends on the quality of the equipment, but also on the quality of the installation. In this project, the GREE FREE MATCH R32 DoubleZone was installed to provide stable comfort, good flexibility of use, and an outdoor solution consistent with the site's constraints.
The elevated outdoor unit, the routing of the lines, the 2-zone configuration, and the start-up checks form a whole that contributes to the reliability of the system. For the customer, this translates into more pleasant daily use, better temperature control, and an HVAC solution adapted to Quebec's seasons.
For homeowners in Repentigny who are considering a DoubleZone heat pump, this achievement shows the importance of choosing a team capable of managing both model selection and installation details. A good installation is never improvised. It is based on experience, precision, and an understanding of the building.

Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
