A reliable and elegant HVAC solution, perfectly suited for Québec’s climate
At AirGreen, we recently completed the installation of a SHARP ZU1 12000 BTU wall-mounted heat pump in a residential home located in Saint-Jean-sur-Richelieu, on the South Shore of Montréal. This unit, known for its performance and energy efficiency, fits seamlessly with the climatic needs of the region and the architectural style of Québec homes.
Here we present the technical details, challenges encountered, and solutions implemented by our team, while highlighting the benefits of this next-generation HVAC system.
A typical suburban home, a harsh Québec winter
The home in question is a well-maintained single-family residence, featuring a traditional stucco exterior, which is very common in the region. As seen in the installation photo, winter conditions were in full effect during our work, with snow covering the ground and outdoor temperatures hovering around -10°C.
These challenging conditions made it all the more important to choose a heat pump designed for northern climates, like the SHARP ZU1.
Why choose the SHARP ZU1 12000 BTU?
The SHARP ZU1 12000 BTU model is a ductless wall-mounted bi-bloc unit, equipped with R-32 refrigerant, known for its low environmental impact. This model strikes the perfect balance between performance, discretion, and energy efficiency, offering key features such as:
-
SEER rating of 21 / 22 for excellent cooling performance
-
HSPF rating of 12.5 / 11 for superior heating efficiency, even in deep winter
-
Heating capacity down to -27 °C, with 7,200 BTU/h at that extreme temperature
-
Exclusive Plasmacluster air purification technology
-
Compact and sleek design, blending perfectly with exterior architecture
Installation process: attention to detail and flawless finish
Initial assessment
Before beginning the installation, our team conducted a complete home assessment to determine:
-
The required heating and cooling capacity (based on orientation, insulation, and room volume)
-
The optimal position for both indoor and outdoor units for maximum performance
-
Accessibility for future maintenance, a crucial yet often overlooked detail
Work completed
-
Precision drilling of the exterior wall to route refrigerant lines and electrical wiring
-
Installation of a protective line hide, vertically aligned on the façade and color-matched to the stucco for near-invisible integration
-
Secure mounting of the outdoor unit on a raised galvanized steel base, protecting it from snow accumulation
-
Pressure testing, air evacuation, vacuuming, and full system startup
Our client praised us for the cleanliness of the job site, the discreet appearance of the system, and the professionalism of the AirGreen team.
