Efficient Climate Control for a Beautiful Île-des-Sœurs Home
At AirGreen, we take pride in providing exceptional HVAC solutions to customers throughout Montreal, Laval, Longueuil, and the surrounding areas. Recently, we completed the installation of a state-of-the-art Gree Livo Gen4 mini-split heat pump in a residence on Île-des-Sœurs (Nuns Island). This installation not only showcased our expertise but also demonstrated how advanced climate control technology can elevate the comfort of any living space.
Why the Gree Livo Gen4 Stands Out
The Gree Livo Gen4 mini-split heat pump, with its 9,000 BTU cooling capacity and impressive heating performance down to -25°C, is the perfect solution for maintaining comfort in both hot summers and freezing winters. This model is especially ideal for homes in Montreal, where temperature fluctuations can be significant.
Key features of this system include:
- Energy Efficiency: Rated at 20.5 SEER, this unit ensures energy savings while maintaining optimal performance.
- Quiet Operation: With sound levels as low as 26 dB(A) indoors and 51 dB(A) outdoors, this heat pump is perfect for homeowners looking for a quiet, serene environment.
- WiFi Integration: Modern homes need smart solutions, and the Livo Gen4 comes equipped with WiFi, allowing homeowners to control their system from anywhere using a smartphone.
- Durability and Warranty: The heat pump comes with a 12-year warranty on parts and the compressor, offering peace of mind for years to come.

The Installation Process: Crafting Comfort in Île-des-Sœurs
Installing this Gree Livo Gen4 mini-split was a meticulous and exciting project. The residence on Île-des-Sœurs needed a reliable, quiet, and efficient system to ensure comfort year-round, and our team was up to the task. After discussing the specific needs with the homeowner, we determined that the 9,000 BTU unit was the ideal size for their space, offering optimal cooling in the summer and robust heating during those freezing Montreal winters.
Step 1: Site Preparation Our expert team began by carefully planning the placement of both the indoor unit and the outdoor compressor. The indoor unit was mounted high on the wall in the living room, ensuring unobstructed airflow throughout the space. Meanwhile, the outdoor unit was installed on a secure base, away from the main foot traffic areas to maintain the home's aesthetics and ensure easy maintenance access.
Step 2: Precision Installation Piping and electrical connections were completed with the highest level of precision. We used 1/4 - 3/8 piping, ensuring seamless and efficient refrigerant flow. The wiring was concealed neatly to preserve the clean look of the home. Special attention was paid to the gas (Freon) type, using R-410A for its environmentally friendly properties and energy efficiency.
Step 3: Testing and Calibration Once the installation was complete, we conducted extensive testing to ensure everything functioned perfectly. The system performed exceptionally, achieving its full heating and cooling potential. The WiFi integration was set up, allowing the homeowner to control the system from their smartphone, even when they are not home. The installation process was smooth, and the homeowner was thrilled with the outcome.
Benefits for the Homeowner: More Than Just a Heat Pump
While the Gree Livo Gen4 heat pump is an outstanding piece of equipment, the true value for the homeowner lies in the combination of energy savings, superior comfort, and convenience. By opting for this system, they will benefit from:
- Year-round Comfort: With its ability to cool and heat efficiently, the Livo Gen4 ensures that the home remains comfortable throughout all seasons.
- Reduced Energy Bills: The high SEER rating means lower energy consumption, helping the homeowner save money while staying eco-friendly.
- Peace of Mind: With a 12-year warranty on the compressor and parts, the homeowner can rest easy knowing their investment is protected for years to come.
- Grant Eligibility: This model is eligible for a $300 LogisVert Grant by Hydro-Québec, making it even more affordable for the homeowner to enhance their home’s comfort.

The job tools
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
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.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
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.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

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.
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.
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.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
