Installation of a GREE LIVO R32 wall-mounted heat pump in Fabreville, Laval: a mini split installed high up in a covered space with reinforced supports

An HVAC installation in Fabreville where the outdoor location made all the difference

In Fabreville, a well-established residential area of Laval, our AirGreen team installed a wall-mounted heat pump GREE LIVO R32, a mini split system designed to provide efficient comfort in cooling and heating while adapting to the real constraints of the building. This project stands out by an essential detail visible in the photo: the outdoor unit was not installed on the ground but rather elevated on sturdy wall mounts, in a covered space like a parking area or integrated shelter.

This setup requires special attention. Installing a heat pump under an existing structure, near a concrete wall, and under framing elements is never an improvised decision. You must consider air clearance, anchor strength, vibration, future access for HVAC maintenance, safe height, and protection against snow, water, and debris.

In this specific case, the GREE LIVO R32 was placed on a pair of metal supports fixed to a solid structure. You can also see blue anti-vibration pads under the unit’s feet, a simple but important technical detail to reduce vibration transmission to the structure. The installation is compact, clean, and designed to last in an environment that imposes more constraints than an open exterior wall.

Why a high installation was the right choice

In Laval, and especially in areas like Fabreville, many properties have side access, covered parking spaces, concrete walls, or outdoor areas where ground clearance is limited. In this project, ground installation could have caused several problems: blocking passage, snow accumulation around the unit, risk of impact, reduced car access, and exposure to water at ground level.

Mounting it high allowed these challenges to be addressed effectively:

  • the outdoor unit stays clear of the ground;
  • the passage under the unit remains usable;
  • the heat pump is better protected against snow accumulation;
  • connections remain accessible for inspection;
  • the support structure limits unwanted movements;
  • the overall appearance remains tidy despite the technical space.

This type of installation, however, requires careful execution. An outdoor unit of a wall air conditioner or a wall-mounted heat pump must remain perfectly level, well secured, and properly cleared so that the fan can expel air without excessive recirculation. In a covered space, this point is even more important, as poor air circulation can reduce system efficiency.

The GREE LIVO R32: a mini split solution adapted to residential needs

The GREE LIVO R32 is a wall-mounted heat pump of the mini split type that is particularly well suited for residential projects where the goal is to improve comfort in a specific area without installing a duct network. It allows heating and cooling of an indoor space with a discreet wall unit connected to a compact outdoor unit.

Its refrigerant R32 belongs to a new generation of residential HVAC devices, with better thermal transfer efficiency than many older refrigerants used in previous systems. For homeowners, this translates into a modern, higher-performing solution better suited to current market demands.

In a house in Fabreville, this type of system can be chosen for several reasons:

  • improve the comfort of a living room, a floor, an office, or an open area;
  • add efficient air conditioning without major ductwork;
  • reduce the use of electric baseboards during certain heating periods;
  • offer more precise temperature control in a targeted area;
  • modernize the property with a compact HVAC solution.

The BTU capacity must always be chosen according to the actual needs of the building. At AirGreen, we do not recommend a heat pump based solely on an approximate area. We take into account insulation, orientation, windows, air volume, interior distribution, room usage, and building configuration. This step helps avoid a unit that is too weak and constantly overworked, or a unit that is too strong and starts and stops too frequently.

Specific challenges observed on this site

The photo shows an installation in an environment where the outdoor unit is placed near a concrete wall, under beams or visible structural elements, with a vehicle parked nearby. This context requires precise coordination between technical performance and the client’s daily reality.

Air clearance around the outdoor unit

A GREE outdoor unit must be able to properly intake and exhaust air. In a covered space, it is necessary to avoid the hot air exhausted during cooling or the cold air exhausted during heating from being drawn back into the unit. Excessive recirculation can make the compressor work harder and reduce efficiency.

Our team therefore paid special attention to the position of the unit, its orientation, and the available space around the fan. The goal was to maintain good air circulation while respecting the physical limits of the site.

The strength of the supports

Installing a wall-mounted heat pump at height requires suitable supports, a solid fixing, and level verification. The supports must be able to bear the weight of the unit, but also the vibrations, start-up cycles, winter conditions, and normal structural movements.

The supports visible in the photo are metal and installed to distribute the load stably. The anti-vibration pads add an extra layer of protection between the unit and its support points.

Proximity to the parking lot

An important detail of this project is the presence of a vehicle under or near the installation area. It was therefore necessary to position the unit so as not to interfere with the normal use of the parking lot, while ensuring sufficient access for the technicians. An installation that was too low would have been exposed to contact risks; an installation that was too high would have complicated maintenance. The right compromise was to place the unit at a functional, safe, and accessible height.

Protection against Quebec conditions

Even in a covered space, an outdoor unit remains exposed to temperature variations, humidity, wind, dust, and freeze-thaw cycles. In Laval, as in Montreal, Longueuil, on the North Shore and the South Shore, the quality of the anchors and finishing plays a direct role in the durability of the installation.

A clean installation, but also designed for maintenance

A good HVAC installation is not judged only on the day the device starts. It is also judged after a winter, after a cooling season, during cleaning, and during inspection. For this reason, we place great importance on future access.

In this project in Fabreville, the outdoor unit is visible, accessible, and placed to allow necessary checks: coil condition, mounting, fan, connections, drainage, and clearance. This accessibility is an element that many homeowners underestimate when comparing quotes.

A poorly placed device can make maintenance longer, more expensive, and riskier. Conversely, a well-thought-out installation simplifies interventions and helps maintain system performance.

Concrete lessons from this GREE LIVO R32 project in Laval

This installation of a GREE LIVO R32 in Fabreville clearly shows that a wall-mounted heat pump project must be adapted to the building, not just the chosen model. The same device can deliver excellent results or cause problems depending on the quality of the installation, the position of the outdoor unit, the protection of the pipes, and the accuracy of the connection.

Mistakes to avoid in a similar installation

For homeowners considering an installation similar to Laval, several mistakes must be avoided.

Installing the unit in a space that is too enclosed

A covered space is not automatically a problem, but it must allow for adequate air circulation. An outdoor unit installed too close to a wall, a low ceiling, or an obstacle can lose efficiency.

Underestimating vibrations

Vibrations can transfer to the structure, especially when the unit is installed at height. Using solid supports and anti-vibration pads is an important precaution.

Placing the unit without considering vehicles or passage

In a parking area, every inch counts. A poorly positioned installation can hinder movement, create a risk of impact, or complicate daily use of the space.

Neglecting access for maintenance

An inaccessible heat pump quickly becomes problematic. It must be possible to inspect, clean, and maintain the outdoor unit without having to dismantle parts or work in a dangerous position.

Choosing capacity in BTU without analysis

The right capacity depends on the actual thermal load. A simple estimate based on area is not always enough, especially in homes with high ceilings, large windows, open areas, or variable insulation.

Why AirGreen places so much importance on preparation

At AirGreen, every project starts with a site analysis. For a GREE LIVO R32 wall heat pump, we assess the indoor location, outdoor location, piping route, distance between units, drain management, electrical supply, access constraints, and final appearance.

This preparation helps reduce surprises and provides a more reliable installation. In the case of this property in Fabreville, preparation was especially important because the outdoor unit had to coexist with an existing structure and a parking space. A rushed installation could have caused clearance, vibration, or access issues.

Local expertise in Laval, Montreal, and on both shores

We regularly carry out installations of wall air conditioners, heat pumps, mini split systems, and other HVAC solutions in Laval, including Fabreville, Sainte-Dorothée, Vimont, Chomedey, Laval-des-Rapides, and Pont-Viau. This local presence gives us a good understanding of common constraints: concrete walls, limited spaces, covered parking, condominiums, semi-detached houses, narrow side access, and tight outdoor areas.

This experience also extends to Montreal, Longueuil, the North Shore, and the South Shore, where buildings often impose different requirements. In some cases, the priority is aesthetics. In others, it is the distance between the indoor and outdoor units. Sometimes, noise management, access to the electrical panel, or integration into a condominium determines the best solution.

Subsidies and eligibility: an aspect to check before purchase

For owners considering a wall-mounted heat pump in Laval, subsidy programs can represent a significant financial advantage. Eligibility, however, depends on the exact model, capacity, current technical criteria, and program conditions at the time of installation.

For a GREE LIVO R32, it is therefore essential to verify the technical information of the installed model before confirming the file. At AirGreen, we help our clients prepare the necessary information, including the brand, model, detailed invoice, and relevant data required by applicable programs.

The final result: a stable, functional installation well adapted to the site

The result of this project in Fabreville is an installation that respects the building's constraints while ensuring a reliable base for the heat pump's operation. The outdoor unit is well supported, placed at height, protected from the ground, and installed with a clean finish. The metal supports, anti-vibration pads, and chosen location demonstrate a consistent technical approach.

For the client, the benefits are clear: better indoor comfort, an effective air conditioning solution for summer, convenient supplemental heating during cooler periods, and an outdoor installation that does not compromise parking use.

This project confirms one important thing: a good HVAC installation depends as much on the team's expertise as on the quality of the machine. The GREE LIVO R32 provides a solid foundation, but it is the precision of the installation that allows the system to deliver its full performance throughout the seasons.
