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.

Careful installation under the awning to maximize performance and lifespan

At AirGreen , we install wall-mounted heat pumps that deliver stable comfort throughout the year, while respecting the architectural features of Montreal plexes. In Villeray–Saint-Michel–Parc-Extension , we installed a Sharp Eco Inverter on a brick facade, mounted on wall brackets and positioned under an awning . This configuration effectively protects the unit from the elements, reduces snow accumulation and promotes clear maintenance access.


Residence context and client objectives

The apartment, located on the ground floor of a typical plex in the neighborhood, had a narrow backyard space. The owners were looking for a compact , quiet , and energy-efficient solution to air condition in the summer and provide heating support in the mid-season. Our recommendation: a Sharp Eco Inverter wall-mounted heat pump , known for its fine regulation and reliability in cold climates, with a sizing between 12,000 and 18,000 BTU depending on the heat load of the main room.


Visible installation details and best practices applied

Positioning under awning
We mount the condenser at a height high enough to stand above the snowpack and splashes. The canopy acts as a natural barrier against ice and sleet, while maintaining the required frontal clearance for air intake/discharge. We maintain side and top clearances in accordance with the manufacturer's recommendations to avoid any air recycling.

Robust and anti-vibration brackets
The galvanized brackets are anchored to the brick using suitable anchors; we add anti-vibration pads, which can be seen in the photo. The result: less structural noise transmitted to the masonry and reduced mechanical wear on the components.

Short and careful refrigeration route
The choice of location allows for a very short refrigerant path to the inner head, with a single piercing and discreet capping . A reduced linearity improves the machine's responsiveness and limits pressure losses , while simplifying future maintenance.

Condensate management and winter
The overhead installation ensures free gravity flow . Under the canopy, the probability of frost sticking to the outer tray is significantly reduced; defrosting is more efficient, which reduces cycles and saves energy .

Food and safety
We provide a dedicated circuit with an appropriate circuit breaker, an accessible disconnect box near the condenser and wiring installed in accordance with the Quebec Electrical Code . This approach guarantees safety , compliance and reliability over time.


Why the Sharp Eco Inverter for Villeray?

Fine modulation and constant comfort
Inverter technology adjusts the compressor speed to maintain a stable temperature without jolts. In use, you will notice fewer variations in airflow and smoother power consumption.

High efficiency and low noise
The streamlined exterior fan and electronic control reduce the noise level perceived in the interior courtyard. For narrow alleys and close neighborhoods, this is a major asset.

Cold weather reliability
Sharp 's Eco Inverter series is designed for our winters. With intelligent defrosting and protected power electronics, the unit maintains its capacity when the mercury drops, ideal for Montreal, Laval , Longueuil , the North Shore and the South Shore .


Key technical steps

  1. Load study and BTU selection
    We calculate the load (area, insulation, air infiltration, orientation). In this case, the main living area justifies a capacity of 12k–18k BTU depending on the solar gains.

  2. Drilling, laying lines and brazing
    The insulated copper connections are nitrogen brazed to prevent internal oxidation. The clamps are spaced evenly to avoid buckling points .

  3. Leak test and high vacuum
    Pressurization with dry nitrogen, followed by a deep vacuum to remove moisture and non-condensables. This is critical for compressor longevity and stable performance .

  4. Commissioning and configuration
    Check for overcurrents , blower temperatures , overheating/subcooling and adjustments to defrost modes according to the sheltered location.


Result obtained

  • Immediate comfort in the main room, with even air circulation .

  • Minimal outside noise thanks to anti-vibration pads and under-awning positioning.

  • Controlled aesthetics : no superfluous visible sheathing, aligned capping, stainless steel screws.

  • Maintenance access preserved: the ladder and awning allow rapid intervention without disturbing the yard.


Operating Tips for the Owner

  • Maintain clear clearance in front of the condenser grille (no bins, bicycles or vegetation within 60–90 cm).

  • In winter, do not clear snow from under the appliance with a metal blade to avoid shocks; use a plastic shovel instead.

  • Program the auto fan speed and a stable setpoint (e.g. 22°C) to fully benefit from the modulation.

  • Schedule annual HVAC maintenance : cleaning the coil, checking currents and drain, updating settings.


Possible grants and savings

Depending on the configuration and efficiency rating of the chosen device, a wall-mounted heat pump may be eligible for current assistance programs . We support our clients in Montreal , Laval , Longueuil, as well as the North and South Shores to prepare the necessary files (proof of installation, performance characteristics, invoices). The AirGreen approach maximizes the profitability of the project from the first season.


What installing under a canopy really changes

  • Less frost and defrost cycles → better seasonal efficiency .

  • Mechanical protection against hail and falling objects → increased lifespan .

  • Sound level optimized by the screen effect of the awning → more peaceful neighborhood .

    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.
