A perfectly adapted HVAC installation for Québec’s harsh winters
At AirGreen, we recently completed the installation of a SHARP ZU1 12,000 BTU wall-mounted heat pump in a residential home located in Blainville, in the heart of Montréal’s North Shore. This project is part of our ongoing commitment to providing our clients with reliable, high-performance, and long-lasting HVAC solutions, built to withstand the toughest winters while optimizing comfort and energy efficiency.
This family home was previously relying on a traditional electric heating system, which was both inefficient and highly energy-consuming during the coldest months. Our experts recommended a SHARP ZU1 wall-mounted heat pump, a strategic choice for its energy efficiency and dependability in extreme weather conditions.
Why the SHARP ZU1 12,000 BTU is ideal for the North Shore

With reliable performance down to -27°C, the SHARP ZU1 is one of the few wall-mounted heat pumps on the market capable of providing consistent heating during the polar cold spells typical of Greater Montréal.

Installation steps: precision and efficiency
The installation was completed in a single day, despite freezing temperatures and snow-covered ground, typical of a February in Blainville.
Main steps included:
-
Site inspection: checking insulation and optimal placement.
-
Indoor wall unit installation: placed to maximize airflow.
-
Outdoor unit mounted on galvanized steel stand: elevated to prevent snow contact.
-
Professional electrical connection: dedicated breaker with a sealed junction box.
-
Startup testing: verifying heating mode efficiency.
The outdoor unit was installed on a raised base, allowing for efficient condensate drainage even during frost, thanks to SHARP’s built-in multiple drainage holes.
Challenges and solutions
This installation required specific adaptation:
-
Older exterior with vinyl siding: we used adjustable spacers to ensure perfect vertical alignment for the wall unit.
-
Tight space between house and fence: the compact yet powerful SHARP ZU1 was the perfect fit.
We also made sure to insulate all refrigerant lines and used a UV-resistant rigid sleeve, ensuring long-term durability even through Québec’s harsh winters.
Immediate comfort and long-term savings
From the moment it was turned on, the SHARP ZU1 heat pump provided a gentle and stable warmth throughout the living area, thanks to its Coanda airflow technology and its wide directional louvers (manual horizontal / automatic vertical).
The homeowner confirmed a noticeable drop in energy consumption compared to their old system, and above all, consistent thermal comfort, even at -20°C.
A smart, grant-eligible investment
This model is eligible for Hydro-Québec’s LogisVert grants, thanks to its high energy efficiency and ability to provide heat down to -27°C. We assisted the client in applying to maximize their return on investment.
