A perfect integration of comfort and innovation
When it comes to ensuring your home's comfort with the latest heating and cooling technology, AirGreen is at the forefront in Montreal. Our recent installation of the Gree Extreme 24,000 BTU wall-mounted heat pump in Montréal-Nord exemplifies our commitment to providing superior HVAC solutions tailored to the unique needs of our clients.
Client vision and our achievement
Nestled in the peaceful neighborhood of Montréal-Nord, a homeowner dreamed of an HVAC system that not only withstands the harsh Canadian winters but does so with remarkable efficiency and minimal disruption to the home's aesthetics. The choice was clear: the Gree Extreme heat pump, renowned for its robust performance even at temperatures as low as -30°C. What set this installation apart was the client's specific request to position the outdoor unit discreetly, ensuring it blended harmoniously with the backyard without compromising functionality.
Features that define excellence
Efficiency at its core: The Gree Extreme is a pillar of efficiency, boasting an impressive SEER rating of 30.5. Equipped with Energy Star® certification, this unit qualifies for Hydro-Québec’s substantial LogisVert rebate, offering our client a $1,860 discount. Its ability to maintain optimal heating power at extreme temperatures while being energy-efficient aligns with our commitment to sustainability.
Quiet yet powerful: With an indoor sound pressure level as low as 22 dB(A), the Gree Extreme ensures a peaceful indoor environment. The outdoor unit operates quietly at 53 dB(A), minimizing noise pollution and enhancing the tranquility of our client’s outdoor sanctuary.
Technological superiority: Integration of WiFi capabilities and the GREE+ app allows effortless control of the unit from anywhere. The innovative G10 inverter technology optimizes temperature regulation and reduces electricity consumption, making this a cost-effective solution for our client.
Warranty and reliability: GREE’s quality promise is backed by a leading 10-year warranty on all components, including labor. This extended warranty underscores the durability and reliability of the Gree Extreme, providing our client peace of mind for years to come.
The installation process: Perfectly tailored
Our skilled technicians approached the installation with precision and care, ensuring every aspect was expertly managed. The indoor unit was installed to align perfectly with the interior décor, while the outdoor unit was strategically placed to avoid any disruption. The use of 1/4 - 1/2 pipes ensured a clean and discreet installation, with all wiring carefully concealed, maintaining the property's aesthetic integrity.

After installation, the homeowner expressed immense satisfaction with both the product and the service. The discreet placement of the outdoor unit and the seamless installation process exceeded their expectations. Their experience is a testament to AirGreen’s dedication to providing not just an HVAC system, but a complete heating and cooling solution that enhances comfort and lifestyle.

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.
