The Silent Comfort Revolution: Gree Livo Gen4's Installation Journey
Introduction to Silent Elegance
In the serene neighborhood of Côte-des-Neiges-Notre-Dame-de-Grâce, AirGreen, your trusted HVAC partner, has once again demonstrated its prowess in delivering top-tier HVAC solutions. Our latest project, a sleek and efficient Gree Livo Gen4 Ductless Heat Pump installation, exemplifies innovation, customer satisfaction, and environmental stewardship. This narrative isn't just about placing a machine in a home; it's a testament to AirGreen's commitment to excellence, customer-centric approach, and technological acumen.
Why Gree Livo Gen4?
Unmatched Efficiency
The Gree Livo Gen4 stands out with its astonishing 20.5 SEER efficiency rating, ensuring your comfort without the hefty energy bill. Its WiFi capability allows seamless control, adding convenience to efficiency.
Designed for Silence
With sound pressure levels as low as 26 dB(A) indoors and 51 dB(A) outdoors, the Livo Gen4 guarantees your peace isn't disturbed. Ideal for placements near living spaces, it whispers comfort.
Robust Warranty and Technical Specs
Backing its superior performance are robust warranty offerings: 10 years for both compressor and parts, with an optional 10-year labor warranty. Its precise engineering, from the 1/4 - 3/8 piping to the 220 V voltage requirement, ensures reliability and performance longevity.
Installation Brilliance
A Challenge Embraced
The task was clear but not devoid of challenges. The client's request was specific: install the external unit on the wall, adjacent to the balcony, ensuring it doesn't encroach on the living space. Our team, known for its ingenuity, rose to the occasion.
Precision and Care
The compressor and indoor units, installed meticulously on the same wall, showcase our team's attention to detail. Our careful planning ensured that the unit's operation would be as silent as a whisper, crucial given its proximity to windows and balcony doors.
Client Delight: A Testament to Excellence
The installation was not just about placing a unit; it was about enhancing a living space. The client's elation at the seamless integration of the Livo Gen4 into their home, coupled with the excitement over the $300 grant from Hydro-Québec, underscores our mission: to exceed expectations.

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.
