An energy-efficient upgrade tailored for a bright condo in southwest Montreal

At AirGreen , we have just installed a Gree wall-mounted heat pump — Livo R32 series —in a condo in the LaSalle district of Montreal. The goal: to provide stable, quiet, and economical comfort for a partially open-plan space, while preserving the interior aesthetics . The result: discreet integration, precise blowing, and tangible energy savings 12 months a year.

The context: a compact space that requires precision and discretion

The living area features white walls and a side window near the chosen location. We chose to install the unit high up on a load-bearing wall to optimize:

  • air stratification (capture of calories in air conditioning mode and improvement of mixing in heating mode);

  • the blowing range towards the main room;

  • visual discretion , the unit aligning naturally above the furniture.

This configuration avoids air recirculation near the ceiling and promotes uniform comfort without direct air currents in the living area.

Why the Gree Livo R32 range?

Gree's Livo R32 range stands out for its high seasonal efficiency , ultra-quiet operation , and discreet display integrated into the front panel—readable from a distance without obstructing the field of vision. Its advantages for a condo in LaSalle:

  • R-32 refrigerant , with lower GWP than R-410A and better suited to current requirements;

  • Inverter compressor finely modulating power, reducing on/off cycles and consumption;

  • Comfort in extreme cold adapted to the Montreal climate, with capacity maintained down to low temperatures*;

  • Quiet mode and multi-directional flaps for comfortable and targeted blowing;

  • Improved filtration for healthier air in urban environments.

*Exact ranges depending on the selected BTU capacity and configuration: we always size the power based on the actual characteristics of the accommodation (exposure, insulation, volumes, glazing).

Sizing and layout: the detail that makes the difference

We size BTU power based on three pillars : winter heat loss, summer solar gain, and occupancy patterns. For this apartment, the 9,000 to 12,000 BTU range is typically adequate; thermal analysis, ceiling height, and glazing orientation guided the final choice in the Livo R32 range .

Interior layout:

  • Intentionally high height to free up useful space and increase the blowing range.

  • Clearances respected around the unit to optimize the sweeping of the shutters and facilitate maintenance.

  • Discreet LED display on the right front: convenient for checking setpoint and operating status at a glance.

Outdoor installation (condenser):

  • Wall brackets with silent blocks to limit vibration transmission to the frame and clear the device of snow in winter.

  • Orientation favoring free air evacuation and safe maintenance access.

  • Short, continuously insulated refrigeration passage to limit losses and maximize SEER/SCOP in actual use.

The technical route: short, clear, efficient

The location—near a wall facing outside —allows for a very short cooling path (approximately 30 to 40 cm from the back of the indoor unit to the outlet). Concrete advantages:

  • Less pressure loss , therefore better performance;

  • Less visual footprint : white capping matching the wall makes the path almost invisible;

  • Gravity evacuation of condensates , without additional pump, therefore increased simplicity and reliability .

We systematically tighten the brazing torques and carry out a deep vacuum (≤ 500 microns) before commissioning to guarantee the absence of humidity and air, essential conditions for the durability of the compressor and stable performance .

Electrical Safety and Compliance

  • Dedicated circuit sized according to nameplate and cable length;

  • Appropriate circuit breaker and external service switch in accordance with standards;

  • Grounding verified and communication conductors clearly marked .

This rigor prevents parasitic triggering and ensures stable communication between the indoor head and the outdoor unit, the key to a high-performance inverter .

Commissioning: Numbers, not guesses

Commissioning includes:

  • Nitrogen leak test ;

  • Vacuum drawing and stabilization;

  • Measurements of blowing/suction temperatures, ΔT in air conditioning, absorbed intensity ;

  • Verification of simulated defrosting and sensors;

  • Timing of the flaps to minimize the effect of “short cycling” of air in the area near the ceiling.

The ΔT observed in cold mode and the stability of the setpoint confirm adequate sizing for the main room, with a comfort margin for the inter-seasons.

Result for the customer: consistent comfort and controlled bill

  • Rapid cooling of main volumes;

  • Efficient supplementary heating during cold peaks, reducing dependence on more energy-intensive systems;

  • Very low noise level : ideal for teleworking and resting;

  • Smoothed consumption thanks to inverter modulation.

HVAC Maintenance: The Winning Schedule

To maintain performance:

  1. Clean filters every 4–8 weeks (more frequently during pollen or construction periods).

  2. Visual check of the capping, clearance of the outdoor unit and condensate drainage at each change of season.

  3. Annual maintenance by AirGreen: deep cleaning of the evaporator, checking of connections, testing of probes, inspection of supports and defrosting.
    Regular maintenance protects the compressor and maintains the advertised performance .

Grants and Eligibility

The Gree Livo range of high-efficiency R-32 wall-mounted heat pumps are generally eligible for Quebec programs (depending on the configuration chosen and the criteria in force), particularly in Greater Montreal: Montreal, Laval, Longueuil, North Shore and South Shore . We support our customers in:

  • eligibility verification (performance range, approvals);

  • preparation of documents (detailed invoices, photos, serial numbers);

  • submission to the relevant programs.

Pitfalls to avoid (AirGreen feedback)

  • Undersize to “save money”: the compressor will run harder, noise and wear increase.

  • Too long refrigeration journey : pressure losses, reduced efficiency, increased bill.

  • Non-gravity condensate drainage when possible: pump unnecessarily stressed and maintenance more cumbersome.

  • Insufficient clearances around the condenser: less efficient defrosting, penalized winter performance.

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.

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):

Before · baseboards11.142¢/kWh
After · heat pump–

Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.

Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.

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.

    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.

    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.
