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.
A Tale of Innovation and Comfort: How AirGreen Transformed a Terrebonne Home
In the heart of Terrebonne, a suburb where the fusion of tranquility and modern living blends seamlessly, AirGreen, a leader in HVAC solutions based in Montréal, undertook a project that epitomizes the perfect marriage of innovation, efficiency, and aesthetics. This narrative details the meticulous installation of a Gree Multi GEN2 DoubleZone Wall-Mounted Heat Pump, a venture that not only challenges the norms of comfort and convenience but also serves as a testament to AirGreen's commitment to excellence and customer satisfaction.
The Challenge and Solution
Finding the Ideal Balance
Embarking on the installation of a Multi Zone heat pump is never a trivial task. The complexity of ensuring the optimal placement of the external unit while seamlessly connecting it to the internal units across different locations within a home demands a high degree of precision and planning. For the residence in Terrebonne, this challenge was met with a tailored strategy that accentuated both functionality and design.
The first internal unit, boasting a robust 24 000 BTU capacity, was strategically placed adjacent to the compressor in the living room, ensuring efficient climate control where it was most needed. The second unit, with a 12 000 BTU capacity, found its home on the opposite side of the house. This ingenious layout guaranteed not only optimal temperature distribution but also underscored AirGreen's knack for harmonizing technical demands with aesthetic considerations.
Invisible Elegance
What sets this installation apart is AirGreen's meticulous approach to concealing the piping within the ceiling and walls, ensuring an unblemished and elegant finish. This attention to detail underscores the team's commitment to delivering solutions that are not only effective but also visually appealing, reaffirming the belief that practicality and beauty can coexist harmoniously.
The Gree Multi GEN2 Advantage
A Beacon of Efficiency and Innovation
The Gree Multi GEN2 stands out as a paragon of HVAC technology, with its 22.0 SEER efficiency rating, Energy Star® certification, and WiFi capabilities, representing the pinnacle of energy efficiency and user convenience. The inclusion of the R-410A gas and a cooling capacity of 36 000 BTU, alongside a heating capacity that remains steadfast up to -30°C, illustrates the unit's superior performance and adaptability to the harshest of climates.
Tailored Comfort with a Provincial Endorsement
This installation was further sweetened by the LogisVert Program grant of $3,696, a testament to the project's alignment with environmental stewardship and energy efficiency standards. The Gree Multi GEN2 not only promises unparalleled comfort but also comes with the assurance of provincial recognition and support.
Client Satisfaction: The Ultimate Reward
A Testament to Professionalism
The resident of Terrebonne was left in awe of the seamless execution and the pristine finish of the installation, a reflection of AirGreen's unwavering dedication to professionalism and customer-centricity. Even amidst the challenges of winter, the team's ability to deliver a flawless project without compromise is a narrative that resonates with all who value quality and precision.

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.
