The full story

The article, chapter by chapter

When these clients from Brossard contacted us, their goal was clear: to replace inefficient heating and cooling solutions with a modern, quiet, and economical system capable of providing true year-round comfort. We recommended the installation of a Gree Inverter R32 wall-mounted heat pump , perfectly suited to a single-family home on the South Shore.


The context of the project in Brossard

The property is a recently built house with red vinyl siding, typical of many residential neighborhoods in Brossard. The clients wanted:

  • A discreet system that does not detract from the facade;

  • A device capable of effectively cooling the ground floor in summer;

  • An efficient supplementary heating solution for mid-season and moderate cold weather;

  • A very low noise level, both inside and outside.

Taking into account the configuration of the house and the targeted energy consumption, our team recommended a Gree Inverter R32 wall-mounted heat pump of approximately 12,000 BTU , an ideal capacity for an open main living area (living room, dining room, kitchen).


The solution: a Gree Inverter R32 wall-mounted heat pump

The Gree brand is known for its reliable, efficient, and very quiet wall-mounted systems. The model installed here is a new-generation Gree Inverter R32 wall-mounted heat pump , which offers:

  • Inverter technology to continuously modulate power, reduce on/off cycles and optimize consumption;

  • R32 (A2L) refrigerant, more efficient and with a reduced global warming potential compared to R410A;

  • An excellent compromise between comfort, energy efficiency and budget;

  • Stable operation both in air conditioning mode in summer and in heating mode during the cooler temperatures of spring and autumn.

Inside, the wall-mounted unit was positioned in the center of the living area to maximize airflow and prevent hot or cold spots. The airflow is gentle and even, allowing you to quickly feel the difference without any unpleasant drafts.


An elevated outdoor installation designed for Quebec winters

The photo clearly shows the Gree outdoor unit installed against the house wall. Several technical choices were made to ensure the installation's durability and ease of maintenance:

  • Elevated aluminum support : the unit rests on a solid metal structure, itself fixed to concrete slabs. This elevation keeps the condenser a safe distance from the ground, protected from snow, ice, standing water and debris.

  • Stability and leveling : the concrete slabs have been adjusted to provide a flat and stable surface, preventing excessive vibration or twisting of the chassis.

  • Sufficient clearance around the unit : the unit is installed with the necessary space at the rear and on the sides to ensure good air circulation and facilitate maintenance interventions.

  • Protection of the coating : the fixings and conduit passages have been designed to preserve the integrity of the house's vinyl coating, limiting unnecessary drilling.

The refrigerant lines, power cable and condensation drain are grouped and protected in a discreet external cover, for a clean aesthetic and additional protection against the elements.


Four-season performance and comfort in Brossard

Thanks to this Gree Inverter R32 wall-mounted heat pump , customers now benefit from:

  • Effective air conditioning during the summer heat waves, even during the frequent heat waves in Greater Montreal;

  • Economical heating in the mid-season , allowing for reduced use of the main system and lower electricity bills;

  • It operates very quietly , both indoors and outdoors, an important advantage in dense residential areas;

  • Better humidity control improves the feeling of comfort and protects the home.

Inverter technology allows the heat pump to adjust its power according to actual demand. The result: fewer temperature fluctuations, optimized energy consumption, and a potentially longer lifespan thanks to gentler operation.


A safe and compliant installation

Our certified technicians carried out the installation in compliance with current standards and industry best practices:

  • Refrigeration connection with vacuuming and leak testing ;

  • Checking the electrical wiring and the dedicated circuit breaker;

  • Complete commissioning with performance measurements;

  • Detailed explanations to owners on the use of the remote control, operating modes and basic maintenance (cleaning filters, clearing the outdoor unit, etc.).

The R32 (A2L) label visible on the unit indicates that the system uses a modern, high-performance, and mildly flammable refrigerant. Our teams are trained to handle these refrigerants safely, in accordance with Code requirements and the manufacturer Gree's recommendations.

Your numbers

The job tools

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

Size checkYour baseboards, in BTU/h
–BTU/h of installed electric heat

    Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.

    The tour

    What we check on a job like this one

    Each number is a point we check on site. Switch between summer and winter to watch air and heat move.

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

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

    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.

    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.
    Is the estimate free?
    Yes. The on-site estimate is free and the quote follows within 24 hours. Book my free estimate.
