A Seamless Fusion of Technology and Comfort
In the charming suburb of Repentigny, just a stone's throw from the bustling city life of Montreal, a residence has been transformed with the latest in heating and cooling technology—a Gree Multi GEN2 DoubleZone Heat Pump. This state-of-the-art installation not only enhances the home's comfort but also its energy efficiency, all while integrating beautifully with the aesthetics of the property.
Project Overview: A Tailored Solution
AirGreen, your trusted HVAC experts in Montreal, recently undertook a medium-complexity project to install the Gree Multi GEN2 heat pump. Known for our meticulous attention to detail and commitment to quality, our team ensured a flawless installation that exceeded expectations.
Key Features of the Gree Multi GEN2:
- Dual Zone Control: Manages two separate zones, with potential expansion up to four zones.
- High Efficiency: Achieves a remarkable 22 SEER efficiency rating, significantly reducing energy bills.
- Advanced G10 Inverter Technology: Ensures reduced power consumption and precise temperature control.
- Energy Star® Certification: Guarantees top-tier energy performance.
- Ultra-Quiet Operation: Maintains a low sound pressure level, making it virtually unnoticeable.
Installation Highlights: Precision and Professionalism
The installation process in Repentigny showcased our team's expertise in delivering not only technical efficiency but also aesthetic harmony. The 30,000 BTU compressor, complemented by a 12,000 BTU and an 18,000 BTU indoor unit, was installed with precision. Both units were strategically placed on the same wall, enabling a seamless integration within the home's design.
Customer-Centric Enhancements:
- Inconspicuous Design: All external pipes and wires were meticulously concealed with white aluminum capping, maintaining the home’s exterior charm.
- Internal Integration: The indoor units were installed to mask any intrusions such as pipes and holes, preserving the interior decor.
- Remote Accessibility: With Wi-Fi-enabled indoor units, the system offers convenient control via smart devices, enhancing user comfort and flexibility.

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.
