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 clean and sturdy outdoor wall installation for a TripleZone GREE system in Laval-des-Rapides
In Laval-des-Rapides, this installation of a TripleZone GREE FREE MATCH R32 heat pump highlights a type of HVAC work that requires much more than just equipment installation. In the photo, the GREE outdoor unit is installed directly on a brick wall, supported by sturdy metal wall brackets, with anti-vibration pads, carefully aligned white finishing ducts, and a refrigerant line passage discreetly integrated into the facade architecture.
This project is representative of the installations we regularly carry out in Laval, especially in residential areas like Laval-des-Rapides, where buildings may have space constraints, ground clearance, exterior finish, and technical access issues. Here, the choice of a wall installation was relevant: it freed up ground space, protected the unit from snow accumulation, and maintained a clean appearance around the building.
The GREE FREE MATCH R32 installed in this residence powers three distinct zones from a single outdoor unit. This 3 zones – 3 heads system allows the customer to independently manage comfort in several rooms without multiplying the units outside. For homeowners looking for an efficient solution for a heat pump, wall air conditioner, and supplemental heating in Greater Montreal, this type of configuration offers an excellent balance between comfort, discretion, and flexibility.
An outdoor unit installed on wall brackets: why this choice is important
The visible installation in the photo shows a GREE outdoor unit mounted on two wall brackets anchored to the structure. This configuration is often recommended when the ground is not the ideal location or when the customer wants to avoid the unit being directly exposed to snow accumulation, leaves, debris, or ground movement.
In Laval-des-Rapides, many properties have compact yards, narrow side passages, or outdoor areas already occupied by balconies, parking spaces, fences, or landscaping. Installing the unit on wall mounts allows better use of space while keeping the device accessible for HVAC maintenance.
In this project, our technicians paid special attention to several essential elements:
- Leveling of the outdoor unit, to ensure stable operation.
- Strength of anchors, especially on a brick wall.
- Vibration reduction, thanks to suitable supports.
- Clearance around the device, to allow good air circulation.
- Protection of refrigerant lines, with white finishing conduits.
- Future access to service panels, to facilitate technical inspections.
A well-installed wall mount not only holds the device. It directly contributes to the system's durability, the occupants' acoustic comfort, and the overall quality of the HVAC installation.
An exterior finish aligned with the facade
One of the most visible aspects of this installation is the cleanliness of the duct routing. The white line covers follow the facade vertically and horizontally, with sharp angles and careful integration around the window and existing structure. This finish is important in a residential neighborhood like Laval-des-Rapides, where the building's exterior appearance matters as much as the device's performance.
A multi-zone installation requires more coordination than a simple system. Since there are three indoor units, the refrigerant lines and communication cables must be organized precisely. A poorly planned outdoor passage can quickly become cluttered or harm the building's aesthetics. Here, the work was done to maintain a tidy appearance while respecting the system's technical needs.
At AirGreen, we place great importance on these details because they influence long-term customer satisfaction. A heat pump that is well installed must operate efficiently, but it must also integrate neatly with the property.
GREE FREE MATCH R32: a multizone solution suited for homes in Laval
The GREE FREE MATCH R32 system is designed for projects where several rooms need to be heated or cooled independently. In this installation in Laval-des-Rapides, the client needed a solution capable of serving three different spaces without installing three separate outdoor units.
The TripleZone configuration allows connecting three indoor units to a single outdoor unit. Each zone can be controlled according to its use, sun exposure, occupancy level, and occupant preferences. This approach is especially useful in homes where some rooms become too hot in summer, while others remain cooler or harder to heat.
The refrigerant R32, used in this GREE range, is one of the modern refrigerants often associated with better thermal efficiency in recent systems. Combined with inverter technology, it allows the device to adjust its operation according to the actual demand of the zones, rather than operating only by abrupt on-off cycles.
For an owner in Laval, Montreal, Longueuil, on the North Shore or the South Shore, this type of system can be particularly relevant when comfort needs to be personalized in several rooms.
A 3-zone system – 3 indoor units: much more than an outdoor device
A common mistake is to judge a multizone system solely based on the outdoor unit. In reality, the success of a TripleZone installation depends mainly on the balance between the three indoor units, the positioning of the outdoor unit, the routing of the lines, and the commissioning.
In a house, each zone has its own needs. An open area with large windows does not require the same capacity as a closed bedroom. A basement does not behave like a room upstairs. A room facing full sun may require a different strategy than a more shaded space.
For this installation in Laval-des-Rapides, our approach was to analyze the entire building before finalizing the configuration:
- approximate area of each zone;
- location of load-bearing walls and windows;
- distance between indoor heads and the outdoor unit;
- drainage possibilities;
- natural air circulation;
- aesthetic constraints on the facade;
- accessibility for work and maintenance.
This planning work results in a more reliable outcome. The client enjoys better-distributed comfort, and the system operates under better conditions.
An AirGreen method focused on precision, durability, and real comfort
The brick wall challenge: fastening, alignment, and vibration
Installing an outdoor unit on a brick wall requires special attention. The wall must allow a solid attachment, the supports must be precisely aligned, and anchors must be chosen according to the material type. Poor fastening can cause vibrations, noise, or stability problems.
In this project, the metal supports were placed to keep the unit at an adequate height while respecting the necessary clearances. The pads visible under the device’s feet help limit vibration transmission to the structure.
This precaution is especially important in residential neighborhoods of Laval, where outdoor units can be installed near occupied rooms, windows, or neighboring properties. A well-thought-out installation reduces nuisances and improves the daily experience of occupants.
Installation height: an advantage in winter
In the photo, the GREE unit is installed above ground level. This height offers a significant advantage in the Quebec climate. In winter, a unit placed too low can be exposed to snow, ice, splashes, and accumulations that reduce air circulation around the device.
A heat pump must be able to properly evacuate air and manage defrost cycles. Poor clearance can harm its operation, especially on cold and humid days. By installing the unit on wall mounts, we reduce these risks while making it easier to access the main components during HVAC maintenance visits.
Finishing ducts: a technical and aesthetic element
The visible white line covers on the facade play an important role. They protect refrigeration lines, cables, and sometimes drains from weather, UV rays, light impacts, and premature wear. They also help maintain a much cleaner appearance than an unprotected line passage.
In a 3 zones – 3 heads installation, duct management becomes even more important because several lines must connect to the outdoor unit. The goal is to avoid unnecessary crossings, poorly organized lengths, and areas difficult to inspect.
Our technicians worked on duct alignment so they integrate naturally with the brick facade. The result is a structured, neat installation that is easier to maintain.
The importance of commissioning a TripleZone system
Once the equipment is installed, commissioning is a crucial step. It confirms that the three indoor units communicate properly with the outdoor unit, that heating and cooling modes work as expected, and that the system responds correctly to each zone's controls.
For a GREE FREE MATCH R32 system, this step notably includes:
- checking the operation of each indoor unit;
- validating communication connections;
- controlling heating and cooling modes;
- checking the drains;
- explaining the controls to the customer;
- usage tips to maximize comfort and system lifespan.
A poorly configured multizone system may work but not provide the expected comfort. That is why AirGreen takes the time to test all zones before completing the project.
Mistakes to avoid in an outdoor wall installation
Many problems observed in the market come from installations that are too quick or poorly planned. For a system like the GREE FREE MATCH R32, it is important to avoid certain shortcuts.
Installing the unit too close to the ground
A unit installed too low can be exposed to snow accumulation, debris, and poor air circulation. In an area like Laval-des-Rapides, this mistake can become problematic from the first winter.
Neglecting vibrations
An outdoor unit mounted directly without precautions can transmit noise to the building structure. Supports, pads, and alignment play an essential role.
Poorly organizing refrigeration lines
In a TripleZone system, poor line management can complicate service, harm the exterior appearance, and create risks of damage.
Choosing the heads without analyzing the rooms
Three heads do not mean three identical needs. Each space must be evaluated according to its size, insulation, windows, and use.
Forgetting service access
An outdoor unit must remain accessible. An installation that is too tight or poorly positioned can make HVAC maintenance longer and more costly.
Personalized comfort for three zones of the house
The main advantage of this installation in Laval-des-Rapides is the ability to control the comfort of three separate spaces. The customer can cool a heavily used area during the day, reduce demand in an unoccupied room, then adjust a bedroom or office according to current needs.
This independent control is appreciated in homes where living habits vary from one room to another. A family may use an open area in the evening, an office during the day, and bedrooms at night. The GREE FREE MATCH R32 TripleZone system allows adjusting the temperature to this daily reality.
This flexibility can also help limit unnecessary expenses. Instead of forcing a single system to treat the entire house uniformly, each zone can operate according to actual demand.
Subsidies and eligibility: check the complete configuration
Subsidy programs for heat pumps can depend on several factors: exact model of the outdoor unit, installed indoor heads, total capacity, energy efficiency, and criteria in effect at the time of the work. For a GREE FREE MATCH R32, eligibility must therefore be validated according to the complete system combination.
At AirGreen, we support customers with the necessary information when the installation is eligible. This can include the detailed invoice, model references, technical documents, and useful guidance to complete the procedures. This assistance is especially appreciated by homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore, as the criteria can vary depending on the available programs.

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.
