See how a strategic installation in Saint-Bruno transforms a home with the Gree Extreme Heat Pump, blending technology with design for ultimate comfort.
Take a tour of the installation
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.
Transforming Comfort One Room at a Time: The Saint-Bruno Success Story
At AirGreen, we pride ourselves on providing top-tier HVAC services across Montreal, Laval, Longueuil, and the North and South Shores. Our mission is simple: to enhance the comfort and quality of living spaces through efficient, reliable heating and cooling solutions. This commitment shines brightly in our latest project, a meticulously executed installation of a Gree Extreme wall-mounted heat pump in Saint-Bruno.
The Heart of the Home: A Strategic Installation
Finding the Perfect Spot
The journey to elevate indoor comfort for our latest client took us to a cozy apartment in Saint-Bruno, where the need for a sophisticated heating and cooling solution was palpable. The client's request was specific and clear: they desired the Gree Extreme wall-mounted heat pump to be installed directly following the bathroom. The strategic placement aimed to optimize airflow distribution throughout the entire apartment, ensuring a harmonious climate in every room.
Navigating the Challenge
The installation posed a medium difficulty level, mainly due to the logistical challenges of integrating the system seamlessly with the existing structure of the apartment. The project required us to maneuver through the bathroom, meticulously installing pipes, electrical wiring, and drainage. Our solution involved routing these components alongside the bathroom, a decision that not only addressed the technical constraints but also preserved the aesthetic integrity of the living space.
A Collaboration of Experts
Seamless Integration
Our team's expertise was complemented by the skills of a professional plasterer, who joined the project to provide the finishing touches. Post-installation, the plasterer worked diligently to ensure a smooth, clean finish, applying a fresh coat of paint that blended the new system into the room as if it had always been there. The result was nothing short of remarkable – a testament to our commitment to delivering installations that are not only functional but also visually appealing.

Sustainable Comfort with Gree
As the world's leading HVAC manufacturer, Gree's commitment to quality, innovation, and sustainability is unparalleled. The Extreme Ultra Heat series exemplifies this dedication, combining high efficiency with environmental responsibility. The use of R-410A refrigerant and high-efficiency G10 inverter technology not only reduces energy consumption but also minimizes the carbon footprint of heating and cooling operations.

The big day, step by step
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 would it look like 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.

Your own project, step by step
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.
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.
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.
