Generic diagram: wall-mounted heat pump, indoor and outdoor units

In summer, the outdoor unit rejects the house's heat outside.

Generic illustration of this type of installation, not a survey of this job site. Tap a number.

  1. 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.

  2. The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.

  3. Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.

  4. A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.

  5. The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.

  6. On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.

  7. The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.

A compact, precise wall installation adapted to a challenging interior space

In Saint-Bruno-de-Montarville, on the South Shore, our AirGreen team installed a GREE LIVO R32 wall-mounted heat pump, also used as a mini split wall air conditioner, in a room where every inch counted. The photo of this project clearly shows the context: an indoor unit installed near a wall corner, above existing wood trim, with a wall surface that required special attention to achieve a clean, functional, and durable result.

This type of HVAC installation may seem simple at first glance. Yet, in a real house, walls are never just walls. You have to deal with woodwork, moldings, clearances, corners, existing materials, the routing of refrigerant lines, condensate drainage, and the ideal location to ensure good air distribution. In this particular case, the goal was clear: to install a high-performance and discreet heat pump, without compromising the room’s aesthetics or the system’s technical quality.

The GREE LIVO R32 was very suitable for this project thanks to its compact wall-mounted design, inverter operation, and use of the R-32 refrigerant. According to the data for the LIVO R32 series published by the manufacturer, this range can reach up to 20.5 SEER2, 12.5 EER2, and 8.8 HSPF2, depending on the exact combination of indoor and outdoor units, with a heating range announced up to about -25 °C.

A difficult wall, but a well-planned solution

The installation was carried out in an indoor area where lateral clearance was limited. The right side of the unit is near a wall return, which requires very precise positioning. A wall-mounted heat pump must not only be visually centered: it must also allow panel opening, filter access, air circulation, and future maintenance without difficulty.

Before fixing the wall plate, our team checked:

  • the solidity of the anchoring surface;
  • the exact level of the unit;
  • the clearance needed for air intake and exhaust;
  • the drilling angle for the passage of pipes;
  • the slope of the condensate drain;
  • the protection of existing woodwork;
  • the cleanest path to the outdoor unit.

In a house in Saint-Bruno, where interior finishes are often meticulous and sometimes older, this step makes all the difference. A poor drain slope can cause water backflow. A poor choice of location can reduce comfort in the room. An imprecise drilling can cause unnecessary damage. At AirGreen, we treat these details as central elements of the work, not just simple site adjustments.

The GREE LIVO R32: a practical choice for residential comfort

The GREE LIVO R32 is a wall-mounted heat pump designed to provide both air conditioning and heating in a mini split ductless format. It is especially aimed at homeowners who want to improve the comfort of a room, a floor, or a specific area without undertaking major renovation work.

In this project in Saint-Bruno, the client was looking for a solution capable of stabilizing the room temperature while maintaining a simple appearance. The white wall unit fits well with the existing decor, and its digital display allows you to quickly see the set temperature. In the photo, the device is set to 20 °C, which clearly illustrates the intended use: stable comfort, without excessive noise or sudden temperature changes.

The inverter operation allows the machine to modulate its power instead of simply starting and stopping repeatedly. This modulation helps maintain a more consistent temperature, reduce short cycles, and improve the overall system efficiency. For a residence in Saint-Bruno, where temperature variations between seasons are significant, this type of technology represents a concrete advantage.

A clean installation despite visible constraints

This project presented a significant aesthetic constraint: the unit had to be installed above an existing wooden element, in an area where the old wall finishes were visible. Our team therefore worked with a very methodical approach to minimize marks, protect surfaces, and maintain a coherent visual alignment.

Installing a wall-mounted heat pump requires precision beyond simply fixing it to the wall. The unit must be slightly positioned to allow condensate drainage, but it must also appear perfectly straight once installed. This is especially important in a room where the line of the woodwork naturally serves as a visual reference. The slightest deviation is immediately noticeable.

We also paid special attention to the outlet of the ducts. In this type of space, a poorly placed passage can become very visible. The goal was to keep the installation as discreet as possible while respecting technical standards: well-insulated refrigerant lines, properly oriented drain, protected wiring, and preserved service access.

Comfort, noise, and air circulation

The position of a wall unit directly affects comfort quality. A unit placed too close to an obstacle may distribute air poorly. A unit installed in a corner without prior consideration can create a cold or hot spot, depending on the mode used. For this installation in Saint-Bruno, our team assessed the airflow direction to maximize diffusion in the room.

The GREE LIVO R32 is suitable for residential spaces where noise level is an important factor. In a bedroom, living room, office, or living area, acoustic comfort matters as much as thermal performance. Proper placement, adequate leveling, and quality installation directly influence the quiet operation of the unit.

A high-performance machine poorly installed can become noisy, vibrate, or lose efficiency. Conversely, a well-executed installation allows the system to operate more smoothly and stably. This is precisely what we seek in every AirGreen project in Montreal, Laval, Longueuil, on the North Shore and on the South Shore.

What this project in Saint-Bruno teaches owners shopping for a heat pump

The exact capacity must be chosen according to the room, not just the price

An essential point in any wall-mounted heat pump project is the choice of capacity. The GREE LIVO R32 range exists in several capacities, but the right choice always depends on the building: area, insulation, solar orientation, ceiling height, number of windows, room use, and presence of other heating sources.

In this project, we emphasized a simple principle: a heat pump that is too small works too hard; a heat pump that is too large can create short cycles and less stable comfort. The right machine is the one that matches the actual need of the room.

That is why AirGreen does not limit itself to proposing a random model. We analyze the space, installation constraints, and client expectations. In Saint-Bruno as in Boucherville, Sainte-Julie, Saint-Basile-le-Grand, Montreal, or Laval, this step helps avoid the most costly mistakes.

Subsidies must be validated with the exact AHRI number

For owners who wish to obtain financial aid, it is important to understand that eligibility does not depend solely on the commercial name of the machine. It depends on the exact combination of the indoor and outdoor units, the AHRI number, and the criteria in effect at the time of the application. Hydro-Québec provides a search tool to verify heat pumps eligible for the LogisVert program.

In the case of a GREE LIVO R32, AirGreen checks the technical data before confirming the information related to subsidies. We also help the client better understand the documents to keep: detailed invoice, indoor model, outdoor model, serial number, proof of installation, and necessary information for the application.

This rigor prevents unpleasant surprises. A client may see a subsidy amount announced on a general sheet, but the actual confirmation must always be made with the installed combination. This is a step we naturally integrate into our service.

Common mistakes to avoid during a wall installation

This project in Saint-Bruno illustrates several mistakes that homeowners should avoid when comparing quotes for an HVAC installation.

The first mistake is choosing the location based only on appearance. The unit should look good in the room, but above all, it must breathe well, drain well, and distribute air properly.

The second mistake is underestimating the importance of the drain. A condensate drain with poor slope can cause leaks, odors, or humidity problems. It is one of the most important elements of a wall air conditioner installation.

The third mistake is comparing only the price without considering the quality of the installation. Two quotes may be for the same device but may not include the same level of finish, the same wall protections, the same quality of piping, the same outdoor support, or the same follow-up after installation.

The fourth mistake is not planning for HVAC maintenance. A wall-mounted heat pump must be cleaned regularly: filters, exchanger, turbine, drain, and outdoor unit. Proper maintenance extends the equipment's lifespan and preserves its performance.

Commissioning, a step we never treat as a formality

Once the unit is installed, our team proceeds with the commissioning. This step includes checking the connections, drainage, communication between units, heating and cooling response, as well as the operation of the vents and the remote control.

In this installation, the 20 °C setting visible on the unit shows that the system was operational at the time of startup. But for AirGreen, seeing the display light up is not enough. We check the device's behavior, the stability of the airflow, and the absence of abnormal noise. We also explain to the client how to use the main modes, how to clean the filters, and how to avoid settings that reduce efficiency.

Why AirGreen is often called for this type of installation on the South Shore

In Saint-Bruno and neighboring municipalities, many homes have unique layouts: rooms with sloped ceilings, existing woodwork, older walls, extensions, finished basements, condos, semi-detached houses, and spaces where the outdoor unit must be carefully placed to respect the neighborhood.

Our experience with heat pump, wall air conditioner, and mini split projects allows us to offer solutions tailored to these realities. We don’t just aim to install a machine quickly. We aim for a durable, clean, compliant, and practical installation for the client.

AirGreen regularly works in Montreal, Laval, Longueuil, on the North Shore and on the South Shore, with an approach that combines technical expertise, respect for the premises, and clear guidance. In this Saint-Bruno project, this approach transformed a challenging space into a functional and discreet installation.

A final result that is simple, efficient, and designed for everyday life

The final result is a GREE LIVO R32 wall-mounted heat pump neatly installed in a tight space, with a visually coherent integration and full commissioning. The client now benefits from a system that can provide cooling in summer and heating in the cold season, while maintaining an installation that’s easy to use daily.

This type of project perfectly sums up our work at AirGreen: analyzing real constraints, choosing a suitable solution, installing with precision, and delivering a result that genuinely improves home comfort.

For Saint-Bruno homeowners considering an HVAC installation, this project shows that a good outcome doesn’t rely solely on choosing a brand. It depends on the entire process: assessment, location, quality of installation, connections, commissioning, client explanation, and post-installation support.

And at your place?

Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.

Before / afterThe cost of the same heat

Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):

    Frequently asked questions

    What people ask us about this kind of work

    12 questions
    Does a wall-mounted heat pump heat in winter?
    Yes, it heats and cools. Its capacity drops in very cold weather; the operating range depends on the model and is listed on its spec sheet.
    Wall-mounted or multi-zone: how do I choose?
    One wall head and one condenser outside: the direct solution for a room or an open area. For two to five rooms, a multi-zone puts one head in each room on a single condenser.
    Where does the outdoor unit go?
    Where it stays above the snow, clear and accessible, away from walkways. We decide it with you during the estimate.
    Are there grants?
    Depending on the model and your situation, assistance programs may apply, including Hydro-Québec's LogisVert. AirGreen checks the model number before quoting an amount. See the grants.
    Do I need a permit?
    Rules vary from city to city: location, distances, noise. See permits and by-laws, and we check for your address.
    How cold can it heat?
    It depends on the model. According to Hydro-Québec, newer models work down to a temperature between −15 °C and −25 °C, and some cold-climate models are certified lower. The minimum temperature is on each unit's spec sheet.
    How much can I save?
    Hydro-Québec says a heat pump can be up to three times more efficient than baseboards for heating in the colder months. The result depends on the house, the climate and how it is used.
    How is the LogisVert assistance calculated?
    For ENERGY STAR cold-climate certified heat pumps, Hydro-Québec lists assistance of $120 per 1,000 BTU/h of heating capacity at −8 °C. AirGreen checks the exact model before quoting an amount; only Hydro-Québec confirms the assistance granted. See the grants.
    Is it noisy?
    The sound level depends on the model and is listed in decibels on each unit's spec sheet. Location matters too: when possible, we avoid putting the outdoor unit under a bedroom window.
    The outdoor unit is covered in ice: is that normal?
    Some frost is: the unit runs defrost cycles. Never hit the ice. If the unit stays iced up or stops heating, call us.
    Does AirGreen hold the required licences?
    Yes. AirGreen holds RBQ licence 5645-9605-01, subclasses 15.8 Ventilation, 15.10 Refrigeration and 16 Electricity.
