A perfectly adapted heat pump installation in Saint-André
At AirGreen, our expertise in HVAC system installations across Montréal, Laval, Longueuil, as well as the North Shore and South Shore, allows us to deliver highly efficient cooling and heating solutions designed to withstand Québec’s harsh winters. Recently, we had another opportunity to demonstrate our know-how by installing a SHARP ZU1 18000 BTU wall-mounted heat pump in the peaceful residential neighborhood of Saint-André.
This project was a great example of how to integrate a high-performance unit into a compact but critical space: a semi-enclosed area under a concrete balcony. While this configuration posed a challenge, our team turned it into an optimized and seamless installation.
Why choose the SHARP ZU1 18000 BTU? A compact powerhouse for Québec’s climate
The SHARP ZU1 wall-mounted heat pump with 18,000 BTU is one of the most advanced models in the ZU1 series, specifically engineered for northern climates. Equipped with R-32 refrigerant, it is environmentally friendly while maintaining high energy efficiency. Here’s what makes this unit ideal for our region:
-
Operates in temperatures as low as -27°C, ensuring reliable heating during the coldest Québec winters.
-
Exclusive Plasmacluster technology: purifies indoor air by neutralizing bacteria, viruses, and mold, and eliminates persistent odors.
-
SEER 24 / HSPF up to 11: excellent energy efficiency in both cooling and heating modes.
-
Compact and quiet wall-mounted design, perfect for single-family homes and small spaces.
A carefully optimized installation in a constrained space
The installation site in Saint-André had a unique constraint: the outdoor unit had to be placed beneath a concrete balcony with limited clearance. Thanks to our on-site experience, we anticipated ventilation, drainage, and vibration-related challenges.
Key installation steps:
-
Foundation preparation: Two stabilized concrete slabs were placed on a compacted gravel bed to ensure a solid base and effective drainage.
-
Galvanized aluminum mounting structure: We selected a raised, corrosion-resistant structure to allow optimal air circulation beneath the unit and facilitate defrosting.
-
Anti-vibration setup: Rubber pads were integrated to minimize vibration and ensure quiet operation.
-
Secure connections: Refrigerant lines and electrical cables were neatly integrated, with weather-resistant protective sheathing.
-
Strategic orientation: The unit was positioned to optimize the discharge of hot air, even in this semi-enclosed space.
Exceptional performance even in winter
Thanks to SHARP’s patented Hot Gas Pipe technology, this ZU1 heat pump can deliver 11,500 BTU/h at -25°C and 10,100 BTU/h at -27°C, maintaining constant comfort even during freezing rain or extreme cold spells.
This ability to perform in very low temperatures is a major advantage for Québec residents who want a primary heating system that is both powerful and energy-efficient.
