A neat outdoor installation on a deck, designed for the climate of Repentigny and the constraints of a backyard
In Repentigny, many homes have friendly backyards, wooden decks, close fences, and facades where windows, outdoor lighting, existing ducts, and service access must be considered before any HVAC installation. For this project, our AirGreen team installed a GREE VITA R32 18,000 BTU wall-mounted heat pump, used as a wall air conditioner, an efficient heating system, and a residential mini split adapted to the needs of a house located on the North Shore.
The photo taken during the work shows a GREE outdoor unit installed on an elevated metal support, directly on a wooden deck. You can also see the real context of the site: a nearby fence, two windows on the facade, hanging string lights, an existing conduit passage near the corner of the building, as well as the commissioning equipment still in place. These are exactly the details that turn an apparently simple installation into a technical project requiring serious planning.
Our goal was clear: to install the machine in a stable, clean, and durable way, without interfering with the use of the deck, without blocking windows, without compromising the outdoor unit’s air clearance, and without creating a messy path for the refrigerant lines. In such a busy residential outdoor space, every decision counts.
Choosing an elevated support to protect the outdoor unit
The outdoor unit is installed on a metal base designed to keep the heat pump above the level of the deck. This choice is especially important in Repentigny, where the accumulation of snow, ice, freezing rain, and defrost cycles can affect the performance of a device placed too low.
An elevated support offers several concrete advantages:
- it limits direct contact with the deck's moisture;
- it protects the unit against accumulated snow;
- it facilitates water drainage during defrost cycles;
- it reduces the risk of vibrations transmitted to the wood;
- it keeps the unit accessible for HVAC maintenance;
- it allows better air circulation around the condenser.
On a wooden deck, stability should never be improvised. We must consider the strength of the boards, load distribution, leveling, future access, and how the unit will behave over several seasons. A poorly installed outdoor unit can move, vibrate, become noisy, or wear out prematurely. Here, the support provides a clean and durable base for the installation while maintaining reasonable clearance around the unit.
An outdoor unit placed in a confined space, without suffocating the condenser
One of the challenges visible in the photo is the proximity of the back fence. A wall-mounted heat pump needs good clearance to reject or capture heat depending on the mode used. In air conditioning, the outdoor unit expels heat from inside. In heating, it captures energy present in the outside air. In both cases, air must circulate properly.
We have therefore positioned the unit to preserve the fan's front clearance and avoid excessive recirculation of hot or cold air. This precaution is essential to maintain system efficiency, reduce compressor effort, and limit performance variations during hot days or cold periods.
In the backyards of Repentigny, Montréal, Laval, Longueuil, the North Shore, and the South Shore, we often encounter similar constraints: fences, balconies, sheds, steps, patio furniture, barbecues, trees, dryer vents, and walkways. Our job is to find the location that respects the building, the use of the yard, and the technical needs of the equipment.
A GREE VITA R32 18,000 BTU chosen for four-season comfort
The GREE VITA R32 18,000 BTU represents a well-suited solution for homes where you want to air condition a main living area, improve supplemental heating, and reduce temperature differences between seasons. The model's technical sheet indicates a cooling capacity of 18,000 BTU, refrigerant R-32, included WiFi, heating capacity down to -25 °C, a SEER2 of 20.0, an HSPF2 of 8.5, an EER2 of 12.4, heating power of 15,300 BTU at -8 °C and 12,100 BTU at -15 °C. It also specifies a voltage of 220 V, piping 1/4 - 1/2 inch, an outdoor sound pressure of 57 dB(A), and a warranty of 10 years on the compressor and 10 years on parts.
This data is important, but it must always be interpreted according to the actual house. An 18,000 BTU capacity may be suitable for an open ground floor, a large family room, an area combining living room, kitchen, and dining room, or a zone where solar gains and occupancy influence comfort. In our analysis, we do not limit ourselves to the surface area. We also assess insulation, window placement, house orientation, indoor air circulation, possible location of the wall unit, and the distance between the indoor and outdoor units.
The GREE VITA R32 series notably includes Inverter technology, WiFi connectivity, a wireless remote control, an option for a wired wall thermostat, a composite drainage pan, copper/aluminum coils, blue fins tested with salt spray, and a refrigerant leak detector according to the manufacturer's documentation. For an owner, these features translate into more practical use, comfort modulation, and better adaptation to temperature variations.
Pipe routing: a technical detail that changes everything
In the photo, you can see the area where the pipes and services must be carefully organized. There are already vertical elements near the wall, cables, an electrical box, windows, and a passage area on the terrace. In this context, the routing of the refrigeration pipes had to be clean, protected, and logical.
The pipes connecting the indoor unit to the outdoor unit carry the refrigerant. Their installation directly influences the system’s efficiency. Too tight a bending radius, poorly protected insulation, poorly planned length, or careless finishing can lead to efficiency losses, condensation risks, or difficulties during future maintenance.
We therefore planned the route to:
- limit visual clutter on the facade;
- protect the insulation of the lines against weather;
- respect access to windows and existing services;
- avoid friction points;
- keep a usable terrace;
- facilitate future interventions.
This finishing work is often what distinguishes a durable installation from a merely functional one. At AirGreen, we treat the piping, drainage, electricity, and outdoor positioning as a whole. The system must work, but it must also remain clean, accessible, and consistent with the house’s architecture.
Commissioning: vacuum pumping, tests, and operation validation
The presence of tools and hoses in the photo shows an essential step: commissioning. Before handing the system over to the client, we check the refrigeration circuit, perform the vacuum pumping, inspect the connections, validate operation in cooling and heating modes, and then confirm that the condensation drainage is adequate.
This step should never be rushed. A wall-mounted heat pump may look well installed visually, but its actual performance depends on the quality of the refrigeration work. The vacuum pumping removes air and moisture from the circuit. Operation tests confirm that the system responds correctly. Final checks help avoid callbacks, abnormal noises, performance losses, or drainage problems.
For the client, we also take the time to explain useful settings: recommended temperature, operating modes, ventilation, dehumidification, filter cleaning, WiFi use, and good habits to avoid making the unit work unnecessarily.
Practical lessons from this AirGreen installation in Repentigny
Preserving the terrace without sacrificing performance
The client wanted an efficient solution but did not want to lose the use of their terrace. This is a common point in residential projects. The outdoor unit must be close enough to the building to allow for an efficient installation, but it must not become an obstacle in daily life.
In this case, we kept a circulation area around the unit while choosing a location near the existing technical passage. The elevated support also helps better define the machine’s space. Once the tools are removed and the finishing completed, the installation remains compact and tidy.
Working around windows and existing elements
The windows visible on the facade required special attention. It was necessary to avoid routing pipes that would interfere with openings, the exterior aesthetics, or future building maintenance work. The string lights, even though they are not related to the HVAC system, also remind us of an important reality: a backyard is a living space. We must respect its use, not just install a unit there.
That’s why our technicians always assess the entire site: facade, terrace, fence, electrical outlets, service access, furniture, natural drainage, snow accumulation areas, and the client’s habits.
Noise: a factor not to be overlooked in a backyard
An outdoor unit installed near a fence or a relaxation area must be positioned carefully. Even though the GREE VITA R32 is designed to operate quietly, the perceived noise can vary depending on the distance, sound reflection on surfaces, the height of the unit, and the support used.
We paid attention to leveling, the sturdiness of the support, and clearance around the unit. A stable base helps reduce vibrations. Good clearance limits the fan's effort. A clean installation also helps avoid rubbing noises or unnecessary movement of the pipes.
LogisVert subsidy: a benefit to verify at the time of application
The AirGreen sheet for the model GREE VITA R32 18,000 BTU shows a LogisVert provincial subsidy of $1,836, with an update indicated as of November 26, 2025. Financial aid programs can, however, change, and eligibility must be verified at the time of the quote, installation, and application. Hydro-Québec states that the owner has nine months from the equipment installation date to submit a financial aid application.
At AirGreen, we provide the customer with the necessary information about the installed model, the detailed invoice, and relevant elements to facilitate the process. For owners in Repentigny, Montreal, Laval, Longueuil, the North Shore, and the South Shore, this assistance can have a significant impact on the final budget of a heat pump installation.
Mistakes to avoid when installing a mini split on a terrace
Installing the unit too close to the ground
A unit placed too low risks being exposed to snow, standing water, and debris. The elevated support used here limits these risks and makes maintenance easier.
Pasting the device against a fence
A condenser needs to breathe. A unit placed too close to an obstacle can lose efficiency, consume more, and run louder.
Neglecting vibrations on a wooden structure
A wooden terrace can transmit vibrations more easily than a well-prepared ground base. The choice of support, leveling, and fastening are therefore essential.
Improvising the pipe routing
A poorly planned routing can make the installation less aesthetic, more fragile, and harder to maintain. Pipes must be protected, insulated, and accessible.
Forgetting future maintenance
A successful HVAC installation must allow access to the outdoor unit, connections, indoor unit filters, and drainage elements. An installation that is difficult to maintain often ends up costing more.
Final result: a clean, stable, and tailored solution for a house in Repentigny
This project in Repentigny clearly illustrates our approach at AirGreen. We don’t just install a machine. We analyze the outdoor space, the structure of the terrace, clearances, facade constraints, client needs, and expected performance. The GREE VITA R32 18,000 BTU wall heat pump was integrated in a way that provides reliable comfort in both summer and winter, while respecting the daily use of the backyard.
For homeowners considering the installation of a wall air conditioner, a heat pump, or a mini split in Repentigny, this project highlights the importance of precise planning. The choice of model matters, but the quality of the installation matters just as much. A good machine poorly installed will never deliver the same results as a system that is properly sized, well positioned, and commissioned with rigor.
AirGreen carries out this type of project throughout the greater metropolitan area, including Montreal, Laval, Longueuil, the North Shore, and the South Shore. Each building has its particularities, each backyard has its limits, and each client has their priorities. Our role is to turn these constraints into a clean, durable, and efficient installation.
