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.

The Customer’s Story: A Quest for Comfort and Energy Efficiency

The Ahuntsic homeowner had been grappling with fluctuating indoor temperatures, particularly during Montreal's icy winters and humid summers. After researching various options, they sought a ductless mini split system capable of delivering both heating and cooling with precision. They chose AirGreen for our stellar reputation, prompt service, and expertise in installing GREE systems—one of the most trusted names in HVAC technology.

  • Powerful Heating Capacity: With a heating range down to -25°C, the LIVO GEN4 is built to combat even the harshest winters in Montreal.
  • Energy Efficiency: Boasting an 18.5 SEER rating, this heat pump delivers exceptional efficiency, keeping energy bills in check while providing year-round comfort.
  • Quiet Operation: The indoor unit operates at a whisper-quiet 32/50 dB(A), ensuring a serene indoor environment.

The Installation Process: Precision and Professionalism

Step 1: Assessing the Space

Our team began by conducting a detailed assessment of the property to determine the optimal location for the indoor and outdoor units. Considering the homeowner’s desire for minimal visual disruption, we selected a discreet spot that ensured efficient air distribution throughout the home.

Step 2: Installing the Indoor Unit

The sleek, wall-mounted GREE LIVO GEN4 indoor unit was installed in the living area, where it could provide maximum comfort. Measuring 37.13 x 9.69 x 13.13 inches, the unit was mounted securely to ensure stability and seamless integration with the room’s decor.

Step 3: Placing the Outdoor Unit

The outdoor unit, with dimensions of 31.63 x 13.88 x 21.88 inches, was strategically positioned to minimize noise impact and exposure to the elements. This placement ensures longevity and optimal performance.

Step 4: Connecting the System

Using high-quality piping (1/4 - 1/2 inch) and environmentally friendly R-410A refrigerant, we connected the indoor and outdoor units. The system’s low-voltage start-up and inverter technology were tested to ensure precise temperature regulation and energy efficiency.

Step 5: Testing and Customer Orientation

Before completing the installation, our technicians conducted rigorous testing to ensure everything was functioning perfectly. We then provided the homeowner with a detailed walkthrough of the system’s features, including how to use the WiFi controls for remote operation.

Performance Highlights of the GREE LIVO GEN4

  • Cooling Capacity: 18,000 BTU ensures rapid cooling during Montreal’s humid summers.
  • Heating Capacity: Reliable warmth even when temperatures plunge to -25°C.
  • Sound Levels: Quiet operation at just 57.0 dB(A) for the outdoor unit.
  • Eco-Friendly Refrigerant: R-410A refrigerant reduces environmental impact while maintaining efficiency.

Your numbers

And at your place?

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.

    Through the seasons

    What to do, season by season

    Three habits per season for this unit. They take a few minutes and prevent many calls.

    • Clean the indoor unit's filters.
    • Clear leaves and debris left on the outdoor unit by winter.
    • Test cooling before the first hot days.

    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.
