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.

An installation designed for an occupied space, with a clean and efficient finish

In the Chomedey sector of Laval, our AirGreen team installed a GREE AIRY R32 wall-mounted heat pump, a mini split system designed to offer excellent comfort in both air conditioning and heating, while discreetly integrating into an already furnished interior space. The photo of this installation immediately shows a context very representative of many projects we carry out in Greater Montreal: a clear wall, a relatively low suspended ceiling, an area occupied by furniture, and a clear need for uniform comfort without cluttering the space.

This type of configuration requires more than just a simple wall mounting. A successful HVAC installation relies on a precise reading of the room, the available clearance above the unit, the direction of the airflow, the ceiling height, technical access for refrigerant lines, and how occupants actually use the room daily. In Chomedey, we approached this project with particular attention to the balance between performance, visual discretion, and perceived comfort.

The GREE AIRY R32 installed here is a modern wall-mounted heat pump that perfectly meets the needs of owners looking for a reliable, efficient, and aesthetic solution for a living room, a light commercial space, a common room, an office, or a versatile area. Its sleek design allows for natural integration on a pale wall, while its modulation capacity ensures stable temperature without abrupt cycles.

Why the GREE AIRY R32 was a relevant choice for this installation in Chomedey

The GREE AIRY R32 model stands out for its use of R32 refrigerant, a technology increasingly sought after in residential and light commercial HVAC. R32 generally offers better energy efficiency than many older refrigerants, while meeting current expectations for performance and more responsible design.

In this project, the choice of this GREE heat pump was justified for several concrete reasons:

  • Discrete wall format, ideal for a space where the interior finish must remain clean.
  • Heating and air conditioning function, allowing multi-season use.
  • Quiet operation, essential in a room where people may be talking, working, eating, or meeting.
  • Good air diffusion, particularly important when a unit is installed near a suspended ceiling.
  • Inverter technology, which adjusts power according to actual demand instead of just on-off operation.
  • R32 refrigerant, appreciated for its energy performance.
  • Sober aesthetic, well suited to light walls and already furnished interior environments.

In Chomedey, as in several sectors of Laval, we often work in buildings where the space available for HVAC equipment is limited. Suspended ceilings, existing partitions, electrical constraints, and aesthetic requirements demand rigorous planning. In this specific case, the wall unit had to be installed high enough to promote good air distribution, while respecting the necessary clearances for maintenance and air circulation.

A clear wall, but a ceiling height to respect

The image shows a unit installed near the ceiling, under acoustic tiles typical of many commercial spaces, offices, or common rooms. This proximity to the ceiling requires careful installation. A unit placed too close to the ceiling may be less effective if air intake is obstructed. Conversely, an installation too low can detract from aesthetics, reduce useful wall space, and compromise optimal air diffusion.

Our team therefore chose a height that allows the GREE AIRY R32 to breathe properly, while maintaining a clean and professional appearance. The result is understated: the unit is well aligned, centered in relation to the available space, and visually light despite its important technical function.

Air diffusion adapted to the actual use of the room

The presence of chairs under the unit indicates that the room is intended to be used regularly by several people. In this type of space, comfort is not limited to achieving a temperature displayed on a remote control. It is necessary to avoid direct drafts on occupants, limit cold or hot spots, and allow for regular diffusion throughout the room.

When installing a wall-mounted air conditioner or wall-mounted heat pump, we pay particular attention to the orientation of the louvers, the distance from seated areas, and the unit's ability to circulate air without causing discomfort. In this project in Laval, the objective was clear: to provide a pleasant temperature, without aggressive airflow, in a room where occupants can remain seated for long periods.

Attention to interior finish

A good installation is not only judged by technical performance. It is also seen in the cleanliness of the final result. On this project, the wall finish had to remain discreet, with no messy visible conduits or unnecessary marks. The white unit blends naturally into the decor, which is particularly important in spaces where the overall appearance of the room matters as much as comfort.

At AirGreen, we place great importance on this dimension. An HVAC installation can be technically correct but visually disappointing if poorly planned. In Chomedey, our intervention resulted in a clean, straight, and consistent installation with the existing environment.

Frequent challenges in this type of installation in Laval

Wall-mounted installations in buildings in Chomedey, Laval, Montreal, Longueuil, the North Shore, and the South Shore often present similar constraints. Even when a room seems simple at first glance, several details must be validated before confirming the final location of the unit.

Among the points we systematically check:

  • The structure behind the wall to ensure solid mounting.
  • Clearance above the indoor unit.
  • Possible routing of refrigerant lines.
  • Location of the condensation drain.
  • Distance between the indoor and outdoor units.
  • Desired sound level in the space.
  • Airflow direction according to room use.
  • Future access for HVAC maintenance.
  • Electrical compliance.
  • Visual impact inside and outside the building.

In this project, the presence of the suspended ceiling required particular attention. Acoustic tile ceilings can sometimes offer useful access for certain checks, but they can also conceal obstacles: beams, wiring, existing ducts, structural elements, or passage limitations. This is why our technicians take the time to validate the environment before finalizing drilling, supports, and connections.

GREE AIRY R32: a solution adapted to four-season comfort needs

The GREE AIRY R32 is aimed at customers who want a compact, efficient, and versatile solution. As a wall-mounted heat pump, it can air condition during warm periods and heat when temperatures drop. For many owners in Laval, this versatility is a major argument, especially when seeking to improve the comfort of a specific room without modifying the entire existing heating system.

Inverter technology allows the unit to adjust its power according to the actual needs of the room. Instead of starting at full capacity and then shutting down completely, the unit modulates its operation. This approach improves comfort, reduces temperature variations, and contributes to better energy efficiency.

For readers comparing several heat pump or wall-mounted air conditioner options, this point is essential. Comfort does not only depend on the number of BTUs. It also depends on the unit's ability to maintain a stable temperature, operate quietly, and adapt to changing room conditions.

The importance of proper sizing

A common mistake is to choose a unit based solely on the approximate area of the room. In reality, sizing a mini split must take into account several factors: ceiling height, insulation, solar orientation, number of windows, room usage, number of occupants, internal heat sources, and air circulation.

In a room like the one in this Chomedey installation, the low ceiling and furniture configuration directly influence the diffusion strategy. A unit that is too powerful could cool quickly, but uncomfortably, with short cycles and temperature variations. A unit that is too weak would run too long without achieving the desired comfort. The right choice therefore relies on a serious evaluation before installation.

At AirGreen, we favor a concrete approach: we observe the space, analyze the constraints, and then recommend a solution that corresponds to the actual use of the building. This method avoids unpleasant surprises and improves long-term satisfaction.

An installation that facilitates future maintenance

Another often overlooked aspect is accessibility for HVAC maintenance. A wall-mounted unit must be easy to clean, inspect, and maintain. Filters must remain accessible, the front panel must be able to open correctly, and internal components must be checkable without excessive intervention.

In this installation, the unit was positioned to maintain sufficient accessibility despite its proximity to the ceiling. This detail is important for preserving the performance of the wall-mounted heat pump over the seasons. A well-maintained appliance works better, consumes less, and has a longer lifespan.

We generally recommend that owners clean filters regularly, especially in frequently used rooms. Dust, airborne particles, and continuous use can reduce airflow if maintenance is neglected. For intensively used systems, periodic professional maintenance also checks the drain, coils, connections, and general operation of the appliance.

Subsidies and energy efficiency: a point to check before purchasing

For homeowners in Montreal, Laval, Longueuil, the North Shore, and the South Shore, available subsidy programs can influence the choice of a heat pump. Certain eligible models can reduce the net cost of the project, depending on the criteria in effect at the time of installation.

The GREE AIRY R32, depending on its exact configuration, capacity, and certifications, may be associated with aid or energy efficiency programs. As conditions can vary according to specific models, serial numbers, official lists, and program updates, we help our customers verify relevant information before finalizing their choice.

This point is particularly important: one should never automatically assume that a device is eligible simply because it is efficient. Eligibility must be confirmed with the exact data of the installed model. At AirGreen, we assist our clients in this verification to avoid administrative errors and unrealistic expectations.

What owners should avoid before a wall-mounted installation

Many problems can be avoided with proper preparation. Before installing a wall-mounted heat pump or wall-mounted air conditioner, we advise against hasty decisions about placement. A wall that seems ideal may hide technical constraints. Similarly, a location chosen solely for aesthetic reasons can negatively impact performance.

The most frequent errors are:

  • Installing the unit too close to the ceiling.
  • Choosing a capacity without a complete evaluation.
  • Neglecting condensate drainage.
  • Placing the unit facing a seated area without adjusting diffusion.
  • Ignoring electrical constraints.
  • Underestimating the importance of the outdoor location.
  • Forgetting future access for maintenance.
  • Comparing only prices without looking at installation quality.

In the HVAC field, the final result depends as much on the appliance as on how it is installed. A good machine poorly installed can become noisy, inefficient, or difficult to maintain. Conversely, a professional installation allows for full utilization of the equipment's capabilities.

AirGreen's expertise in wall-mounted installations in Chomedey and Greater Montreal

AirGreen regularly performs installations of wall-mounted heat pumps, wall-mounted air conditioners, and mini split systems in various environments: single-family homes, condos, small businesses, offices, common rooms, rental housing, technical spaces, and mixed-use premises. This diversity allows us to adapt our method to each project.

In Chomedey, the reality on the ground is often particular. The sector includes residential buildings, condominiums, local businesses, and older buildings where installations must respect existing constraints. Our local experience helps us anticipate challenges: outdoor access, conduit passages, condominium requirements, facade aesthetics, parking for the team, noise, and coordination with occupants.

We apply the same rigor throughout Greater Montreal, whether in Montreal, Laval, Longueuil, on the North Shore or on the South Shore. Each installation is planned to deliver a reliable, clean, and durable result.

A sober, practical, and comfortable final result

The result of this installation in Chomedey perfectly illustrates our approach: a precisely installed GREE AIRY R32, a discreet visual finish, a position adapted to the room, and a comfort solution that respects the actual use of the space. The unit does not dominate the decor. It performs its role efficiently, without cluttering the wall or disturbing the layout.

For occupants, the difference is mainly felt in the stability of comfort. A room that became too hot in the summer or difficult to keep pleasant during transitional periods can now benefit from much more precise control. The heat pump offers a quick, yet modulated, response, which is very suitable for spaces occupied for several hours.

    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.
