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.

A Quiet Revolution in Home Comfort: Bringing the GREE LIVO GEN4 to Saint-Constant

At AirGreen, we pride ourselves on delivering exceptional HVAC solutions tailored to the unique needs of our clients. Recently, we had the privilege of installing a GREE LIVO GEN4 Ductless Heat Pump in a charming residence in Saint-Constant. This project showcases not only the cutting-edge technology of the GREE LIVO GEN4 but also our meticulous approach to ensuring every installation exceeds expectations.

About the GREE LIVO GEN4: A Perfect Blend of Efficiency and Style

When it comes to energy-efficient heating and cooling, the GREE LIVO GEN4 stands in a league of its own. Designed to provide seamless year-round comfort, this 12,000 BTU unit is a versatile solution for Quebec’s demanding climate. Its 18.5 SEER efficiency rating ensures that homeowners can enjoy optimal comfort without worrying about skyrocketing energy bills.

Here are some key features that make the GREE LIVO GEN4 a top choice:

  • Heating Capability Down to -25°C: Perfect for Quebec winters, this unit doesn’t just keep you warm—it keeps you cozy even in the most frigid conditions.
  • Whisper-Quiet Operation: Operating at just 27 dB(A) indoors, the GREE LIVO GEN4 ensures your home remains a peaceful retreat.
  • WiFi Connectivity: Adjust the temperature remotely using your smartphone for unmatched convenience.
  • Compact Dimensions: With an indoor unit measuring 32.88 x 7.88 x 10.88 inches, it blends seamlessly into any space without compromising aesthetics.

The Saint-Constant Installation: A Story of Precision and Excellence

Every HVAC installation tells a story, and this one is no exception. The homeowner, a family seeking an energy-efficient solution to combat the harsh winters and humid summers of Quebec, reached out to us for a consultation. They were particularly drawn to the LogisVert Grant by Hydro-Québec, which offered a $340 rebate for the GREE LIVO GEN4.

Step 1: Assessing the Space

Before installation, our team conducted a thorough assessment of the home. The goal was to determine the optimal location for both the indoor and outdoor units to ensure maximum efficiency and aesthetic appeal. Given the compact size of the LIVO GEN4, we were able to identify a discreet yet effective placement for the indoor unit in the living area.

Step 2: Precision Installation

Our technicians got to work, adhering to the highest standards of quality. The indoor unit was mounted securely, ensuring proper alignment for efficient airflow. Special care was taken to conceal the piping and wiring, maintaining the clean, modern look of the space. The exterior unit, with its dimensions of 28.81 x 13 x 21.88 inches, was installed on a sturdy base to ensure durability and performance

even during extreme weather conditions.

Step 3: System Optimization

Once the installation was complete, our team conducted a series of tests to ensure the system was operating at peak efficiency. We calibrated the GREE LIVO GEN4 to meet the specific needs of the homeowner, ensuring consistent airflow and maintaining optimal temperature levels throughout the home.

Why the GREE LIVO GEN4 Is a Game-Changer for Saint-Constant Residents

Living in Saint-Constant means facing a wide range of weather conditions—from sweltering summers to freezing winters. The GREE LIVO GEN4 Ductless Heat Pump is perfectly suited for this environment. Its G10 inverter technology allows it to adapt to fluctuating temperatures with ease, delivering reliable comfort no matter the season.

Energy Savings

One of the standout benefits of the LIVO GEN4 is its ability to lower energy consumption. By maintaining a consistent indoor temperature, it eliminates the need for energy-draining start-and-stop cycles.

Quiet Comfort

Unlike older HVAC systems that can be noisy and disruptive, the LIVO GEN4 operates so quietly that you’ll hardly notice it’s there. This is particularly important for families or individuals who value a serene home environment.

The LogisVert Grant: Making Comfort Affordable

We understand that upgrading to a high-quality HVAC system is an investment, which is why we always help our customers take advantage of available rebates. In this case, the LogisVert Grant by Hydro-Québec provided a $340 rebate, making the GREE LIVO GEN4 an even more attractive option for the homeowner.

The steps

How it goes, from the first call to the end

The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.

Step 1 of 9The on-site estimate

We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.

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.
