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 Precision: How AirGreen Mastered a Challenging Installation
In the heart of Laval, a groundbreaking event unfolded as AirGreen embarked on an intricate journey to install a Gree Multi GEN2 DoubleZone Wall-Mounted Heat Pump, a feat that not only tested our expertise but also showcased our commitment to excellence and innovation in HVAC solutions. This narrative not only chronicles our journey but also highlights why AirGreen is the preferred choice for HVAC projects across Montreal, Laval, Longueuil, North Shore, and South Shore.
Understanding the Challenge
At the outset, let's delve into the specifics of the Gree Multi GEN2, a 36 000 BTU powerhouse with two 18 000 BTU indoor units designed to provide unparalleled comfort. The complexity of this installation lay not in the technology itself but in the meticulous planning required to ensure optimal placement of both indoor and outdoor units. This complexity was classified as medium, underscoring the need for precision and strategic thinking.
The Journey to Seamless Installation
The story of this installation is one of technical prowess and innovative solutions. The primary hurdle was the placement of the outdoor unit and the strategic installation of the two indoor units on opposite sides of the house. The proximity of one unit to the compressor presented a straightforward task, but the second unit, located near the center of the house, posed a significant challenge.
Our team's commitment to excellence was on full display as we engineered a solution to conceal the piping within the walls, ensuring a clean and aesthetically pleasing outcome. This approach minimized structural impact on the house, leaving our customer thoroughly impressed with the ingenuity and cleanliness of the installation.
Gree Multi GEN2: A Closer Look at Excellence
The Gree Multi GEN2 is not just any heat pump; it is a testament to energy efficiency and advanced technology. Equipped with WiFi capabilities and boasting an impressive 22.0 SEER efficiency rating, this model is a paragon of modern HVAC solutions. The ENERGY STAR® certification and the AHRI number 210278979 affirm its quality and performance standards.
Furthermore, the unit is powered by a 220V supply, ensuring robust performance with a sound pressure level of 63.0 dB(A), making it as powerful as it is quiet. The R-410A gas ensures environmentally friendly operation, and the cooling and heating capacities are designed to withstand even the harshest Canadian winters, with heating efficacy down to -30°C.
The Reward: Satisfaction and Recognition
This installation was not just about overcoming technical hurdles; it was about delivering value and satisfaction to our client. The successful installation made our client eligible for the Provincial Grant: LogisVert Program, amounting to $3696, a significant saving that underscored the economic benefit of choosing AirGreen for their HVAC needs.

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.
