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 Seamless Integration with Stunning Efficiency
The Context: A Simple Yet Significant Upgrade
In the serene neighborhood of Saint-Eustache on Montreal’s North Shore, a recent HVAC installation by AirGreen not only elevated home comfort but also showcased the seamless marriage of efficiency and user-friendliness. This project centered around replacing an antiquated air conditioning unit with the Gree Vireo GEN3, a ductless heat pump renowned for its stellar performance and quiet operation.
Installation Highlights: Precision and Customer Satisfaction
The Challenge and Solution
Often, HVAC upgrades can be daunting for homeowners, fearing complex installations and lengthy disruptions. However, our latest project in Saint-Eustache was anything but. Classified as a simple job, the installation was streamlined thanks to the compatibility of the existing infrastructure with the new system. Here’s how we achieved a hassle-free transition:
-
Reusing Existing Components: The ability to use the existing 20A electrical wiring and 1/4 - 1/2 inch piping not only expedited the installation but also significantly reduced the overall cost. This reuse approach is a testament to our commitment to sustainable practices and cost-efficiency.
-
Thorough Inspection and Maintenance: Despite the straightforward nature of the job, our team took no shortcuts. We meticulously inspected the existing pipes for leaks and cleaned them with a specialized solution, ensuring they were as good as new before installing the new unit.
Client Involvement and Feedback
The transparency of our process and the active involvement of our client in the decision-making process were crucial. The homeowner's readiness to engage and provide input made the installation smoother and more tailored to their needs. Their satisfaction was palpable, leading them to refer us to family members, expanding our community of satisfied customers through genuine word-of-mouth.

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.
