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.
Mastering Aesthetics and Efficiency: A Unique HVAC Installation
In the heart of Saint-Laurent, Montreal, AirGreen has completed a distinctive and technically sophisticated installation of a Gree Free Match Extreme DoubleZone Heat Pump. This project not only showcased our commitment to energy efficiency and modern living but also emphasized our meticulous attention to aesthetic detail and integration within a residential setting.
The Challenge: Blending Functionality with Style
The primary challenge in this project was the seamless integration of the system into the client's existing home architecture. The location demanded a careful and strategic placement of the outdoor unit and indoor heads to ensure optimal functionality without compromising the home's visual appeal. Our team was tasked with installing an 18,000 BTU compressor paired with two 9,000 BTU indoor units, which required precision and thoughtful planning to achieve a balance between efficiency and design.
Strategic Installation Approach
The installation involved the strategic positioning of the Gree Free Match Extreme system to maximize cooling and heating efficiency. The outdoor unit was installed under an existing stairway canopy, providing it with protection and reducing its visual impact on the exterior aesthetics of the home. To enhance the visual cleanliness of the installation, we meticulously concealed all pipes and electrical wiring, embedding them within the structure in a way that maintained both the integrity and the charm of the property.
Innovations and Features of the Gree Free Match Extreme
- High Efficiency: With a SEER rating of 23.0, this system offers one of the highest levels of efficiency in the market, significantly lowering energy costs while providing superior comfort.
- Eco-Friendly Technology: Utilizing the R-410A eco-responsible refrigerant, the system aligns with modern environmental standards, reducing the carbon footprint.
- Robust Weather Resistance: Engineered to perform in temperatures as low as -35°C, ensuring reliable heating during the harsh Montreal winters.
- Smart Connectivity: Equipped with WiFi capabilities, allowing homeowners to control their climate settings from any smart device, enhancing user convenience and energy management.

Client-Centric Solutions and Service
Our approach always centers around the client’s specific needs and aesthetic preferences. For this installation, meticulous planning and skilled execution were crucial to delivering a solution that not only meets the functional requirements of temperature control but also enhances the living space.

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.
