Installation of a Gree Crossover Wall-Mounted Heat Pump in Varennes, South Shore
Witness how a silent, compact Gree Heat Pump transforms a Varennes home with style and efficiency — installed flawlessly by AirGreen.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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 of Comfort and Technology
Unveiling the Essence of Modern HVAC Solutions
In the charming town of Varennes, located on the picturesque South Shore, a recent installation by AirGreen has captured both attention and admiration. Our team successfully installed a Gree Crossover Wall-Mounted Heat Pump, a model that epitomizes efficiency and quiet operation. This installation was not just about enhancing home comfort; it was about integrating a state-of-the-art system designed to meet the exact needs of our customer.
Customer-Centric Approach
The installation site, a serene residence in Varennes, was the perfect backdrop for this sleek and powerful unit. Our customer had clear requirements: compactness, silence, and efficiency. The Gree Crossover, with its 12,000 BTU capacity, rose to the occasion, proving that you don’t have to compromise power for size or peace.
Key to this project was the unit's compact design, ensuring that it fit seamlessly into the limited space available without dominating the aesthetic of the room. Moreover, the low sound levels of 27 dB(A) indoors mean that comfort comes silently. This feature was paramount for our client who emphasized the importance of a non-intrusive system that performs without the constant reminder of its presence.
Technical Precision and Aesthetic Harmony
Our technical team showcased their expertise not just in selecting the right unit but in executing an installation that aligns perfectly with the client’s vision. The installation process was smooth, marked by meticulous attention to detail. Pipes and wiring were cleverly concealed within the walls, ensuring that the sleek look of the interior was maintained. This attention to aesthetic detail was particularly appreciated by our client, who was thrilled with the unobtrusive integration of the system into their home.
Energy Efficiency and Eco-Friendliness at Its Best
The Gree Crossover is not just any heat pump; it’s a beacon of sustainability and high efficiency, boasting an impressive 25.0 SEER rating. It also features GREE's exclusive G10 Inverter technology and a multi-speed fan that adjusts to optimize energy use while maintaining comfort levels. Equipped with Energy Star® certification, this unit was eligible for a $385 provincial grant under the LogisVert Program by Hydro-Québec, making it an economically smart choice as well.
Long-Term Reliability Guaranteed
Recognizing the importance of reliability and customer peace of mind, AirGreen provided a comprehensive 10-year warranty covering the compressor, parts, and labor. This extensive warranty underlines our commitment to quality and our confidence in the Gree products we install.
Community Impact and Customer Satisfaction
The impact of our installation extended beyond the confines of a single home. The professionalism displayed and the quality of the work performed led our client to recommend AirGreen to their neighbors. This word-of-mouth endorsement is a testament to our dedication and the trust our clients place in us.
This recent installation in Varennes is more than just a testament to AirGreen's expertise in HVAC solutions; it's a reflection of our commitment to providing our clients with systems that enhance comfort while maintaining environmental responsibility and aesthetic integrity.

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.
