Installation of a Gree Extreme Wall-Mounted Heat Pump in Île-Bizard–Sainte-Geneviève
Discover unparalleled home comfort with the Gree Extreme Heat Pump—engineered for performance, designed for life in Île-Bizard–Sainte-Geneviève.

In summer, the outdoor unit rejects the house's heat outside.

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.
Unleashing Efficiency and Comfort: A Case Study in Advanced HVAC Solutions
In the heart of Île-Bizard–Sainte-Geneviève, a suburban treasure nestled in Montreal, a new chapter in home comfort has been written, courtesy of AirGreen. Our recent installation of the Gree Extreme Wall-Mounted Heat Pump stands not just as a testament to cutting-edge technology but also reflects our commitment to sustainability and superior customer satisfaction. This narrative delves into the intricate details of the installation and the sophisticated features of the Gree Extreme model, which has garnered attention for its exceptional performance and energy efficiency.
Project Overview
The task was to equip a family residence with a high-performance HVAC system capable of withstanding the rigors of the Canadian climate while offering substantial energy savings. The chosen location, Île-Bizard–Sainte-Geneviève, known for its scenic beauty and tranquil living, demanded nothing short of excellence in both functionality and aesthetics.
Choosing the Right Model
After careful consideration, the Gree Extreme model was selected for its robust specifications and suitability for the local climate. This model is renowned for its:
- Energy Star® Certification: Yes
- WiFi Capability: Included
- AHRI Number: 9123256
- Efficiency Rating: 21.5 SEER
- Comprehensive Warranty: 10 years on the compressor, parts, and labor
- Additional Coverage: Included
- Sound Pressure Levels: 59 dB(A) outdoor, 34/54 dB(A) indoor
- Eco-friendly Refrigerant: R-410A
- Heating Capacity: Functions effectively down to -30°C
Installation Highlights
Our team faced the challenge of integrating this sophisticated system into the existing structure without disrupting the home’s aesthetic or integrity. The installation included:
- Customized Piping: The use of 1/4 - 5/8 tuyauterie ensured a seamless fit.
- Optimal Placement: Strategic positioning of both the indoor and outdoor units to maximize efficiency and minimize noise.
- Voltage Requirements: Careful handling of the 220V requirement to ensure safety and compliance with local electrical standards.
The outdoor unit was mounted on a sturdy, anti-vibration bracket which not only stabilizes the unit but also reduces operational noise, a critical consideration in residential areas.
Technological Advancements
The Gree Extreme heat pump is a marvel of engineering, designed to deliver top-notch heating and cooling performance under extreme weather conditions. It features:
- Two-Stage Compressor: This allows for greater efficiency and comfort by adjusting cooling and heating cycles to precise room conditions.
- High-Quality LED Display: For easy monitoring and control.
- Dust Filters: High-quality, easily washable filters ensure a cleaner air supply.
- Turbo Mode: Rapidly adjusts room temperature for immediate comfort.
- Temperature Sensor in Remote Control: Provides accurate readings that enhance operational efficiency.
Sustainability and Energy Efficiency
This installation not only meets but exceeds the expectations for energy efficiency, making the homeowners eligible for a $1860 LogisVert Grant by Hydro-Québec. The high SEER rating ensures that energy consumption remains low, while the eco-friendly R-410A refrigerant makes it a responsible choice for environmentally conscious homeowners.
Client Testimonial
The homeowners expressed immense satisfaction with the functionality and the aesthetic fit of the Gree Extreme system. They noted significant improvements in home comfort and a noticeable reduction in their energy bills. The ease of use and the quiet operation of the system were also highlighted as major benefits.
Conclusion
The installation of the Gree Extreme Wall-Mounted Heat Pump in Île-Bizard–Sainte-Geneviève by AirGreen is a perfect example of how modern technology can be seamlessly integrated into residential spaces without compromising on style or comfort. This project not only underscores our expertise in HVAC solutions but also our dedication to providing energy-efficient and sustainable options for our clients.
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.
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.

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.

And at your place?
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.
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.
