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.
The Challenge of Comfort: A Unique HVAC Journey
Understanding the Complexity of a Superior Installation
When the residents of Saint-Léonard seek unparalleled comfort and efficiency in heating and cooling solutions, they turn to us, AirGreen, the leading HVAC experts in Montreal and its surrounding areas. Our latest project, a testament to our dedication and expertise, involved the installation of a Gree Vireo GEN3 Ductless Heat Pump. This task was not just another routine job; it was a complex challenge that showcased our team's ability to overcome seemingly insurmountable obstacles.
The Heart of Innovation: Gree Vireo GEN3 Ductless Heat Pump
The centerpiece of this installation was the Gree Vireo GEN3 Ductless Heat Pump, a marvel of modern HVAC technology. With a 9 000 BTU capacity, this machine is designed to provide exceptional comfort while being remarkably energy-efficient, boasting an impressive 25.3 SEER rating. Additionally, the inclusion of WiFi capabilities, an Energy Star® certification, and a robust warranty package highlight its advanced features and reliability.
Silence and Efficiency: The Ultimate Comfort Duo
A critical aspect of this installation was ensuring the indoor unit's quiet operation, especially given its placement in a bedroom. The Vireo GEN3 excels in this area, with an interior sound pressure level of just 25/40 dB(A), ensuring restful nights undisturbed by machine noise. This feature, coupled with the unit's energy efficiency, makes it an ideal choice for those prioritizing both comfort and sustainability.
Overcoming Obstacles: A Testament to Expertise
The installation posed unique challenges, particularly regarding the placement of the outdoor unit and the routing of pipes and wires to the bedroom. Our team's innovative approach involved installing the outdoor unit on one side of the house and expertly hiding the necessary conduits within the walls to reach the bedroom discreetly. This not only preserved the home's aesthetic but also exemplified our commitment to delivering tailored solutions.
Precision and Care: Ensuring a Seamless Experience
Another significant challenge was managing the drainage system, necessitating a long drainage pipe and the installation of a compact, silent drain pump. This meticulous work ensured that no water leakage would occur inside the property, reflecting our attention to detail and our pledge to exceed customer expectations.
Customer Satisfaction: The True Measure of Success
The end result of this complex installation was a highly satisfied customer, thrilled with the seamless integration of the system into their home and the enhanced comfort it provides. This project stands as a vivid illustration of AirGreen's commitment to delivering exceptional HVAC solutions that are not only effective but also aesthetically pleasing and tailored to individual 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.
