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.

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.
Elevating Comfort in the Heart of Montreal's Retail District
In the bustling retail environment of Montreal, where every square inch and every detail counts, the installation of a state-of-the-art Gree Extreme Wall-Mounted Heat Pump represents more than just an upgrade in heating and cooling—it symbolizes a commitment to enhanced customer experience and operational excellence. AirGreen is proud to showcase a recent HVAC project that not only underscores our technical expertise but also highlights our dedication to energy efficiency and sleek design integration.
Project Overview
Nestled within a charming shoe store in Montreal, the latest AirGreen installation goes beyond mere functionality. This project was about creating a space where customers can shop in absolute comfort, no matter the weather outside. Here’s a glimpse into the unique aspects and challenges of this installation:
- Location: A high-traffic shoe store in Montreal
- Challenges: Integrating a large-scale HVAC system without disrupting the aesthetic and flow of a stylish retail space
- Solution: Gree Extreme Wall-Mounted Heat Pump, known for its unobtrusive design and powerful performance
Technical Excellence and Aesthetic Harmony
The Gree Extreme Wall-Mounted Heat Pump is renowned for its impressive 21.5 SEER efficiency, making it one of the most energy-efficient models on the market. Designed to handle extremes, it offers a cooling capacity of 24,000 BTU and can heat effectively down to -30°C, ensuring year-round comfort. The unit's smart features, including WiFi connectivity and a high-quality LED display, allow for effortless control and monitoring.
Design Integration
Integrating such a powerful unit into a refined retail environment posed its challenges. The design needed to be minimally invasive while maximizing comfort. The installation site was strategically chosen above the entrance, providing optimal air distribution without detracting from the store’s modern décor. Our team ensured that the unit blended seamlessly with the store's aesthetic, maintaining a clean look with the interior dimensions measuring 42.52 x 9.66 x 12.81 inches.
Sound Optimization
One of the critical considerations for any retail space is maintaining a pleasant shopping environment, which includes noise levels. The Gree Extreme operates exceptionally quietly, with an indoor sound level of 34 dB at its lowest, akin to a whisper. This feature is crucial in a retail setting, ensuring that the comfort of air conditioning does not come at the cost of disruptive noise.
Sustainable and Smart Technology
In today’s eco-conscious market, the Gree Extreme stands out with its R-410A refrigerant, known for its lower environmental impact. The two-stage compressor and auto start features not only enhance the pump's efficiency but also its longevity. Furthermore, the unit's special anti-corrosion coating protects against the harsh Canadian winters, ensuring durability and consistent performance.
Energy Star Certification and Grants
This installation is not only a win for the store's comfort but also for its finances. The unit is Energy Star® certified and qualifies for the $1860 LogisVert Grant by Hydro-Québec, making it an economically smart choice. These benefits underscore the unit’s alignment with sustainability goals and financial savvy.

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.
