A HVAC installation perfectly suited to Quebec's harsh climate
At AirGreen, we recently completed the installation of a SHARP ZU1 12,000 BTU wall-mounted heat pump in a residence located in Blainville, in the heart of the North Shore of Montreal. This installation reflects our ongoing commitment to providing our clients with reliable, efficient, and durable HVAC solutions capable of withstanding the harshest winters while optimizing comfort and energy efficiency.
This family property had previously relied on a traditional electric heating system, which was inefficient and particularly energy-consuming during the coldest months. Our experts recommended a SHARP ZU1 wall-mounted heat pump, a strategic choice both for energy efficiency and reliability in extreme climates.

With optimal operation down to -27°C, the SHARP ZU1 is one of the few wall-mounted heat pumps on the market capable of maintaining consistent warmth even during the polar episodes typical of the Greater Montreal area.

Installation steps: precision and efficiency
The installation was completed in one day, despite subzero temperatures and snow-covered ground, typical of February in Blainville.
Here are the main steps:
-
Site inspection: checking insulation and optimal placement.
-
Installation of the indoor wall unit: positioned to maximize air distribution.
-
Mounting the outdoor unit on a galvanized steel bracket: elevated to avoid direct contact with snow.
-
Professional electrical connection: with dedicated circuit breaker and waterproof junction box.
-
Commissioning tests: verifying heating mode efficiency.
The outdoor unit, installed on an elevated base, allows for efficient condensate drainage even during frost periods, thanks to the multiple drainage holes designed by SHARP.
Challenges encountered and solutions provided
The installation required specific adaptation:
-
Old exterior wall with vinyl siding: we used adjustable spacers to ensure the perfect alignment of the wall unit.
-
Limited space between the house and the fence: the choice of the compact yet efficient SHARP ZU1 model proved ideal.
We also took care to properly insulate the refrigerant lines and use a UV-resistant rigid conduit to ensure maximum durability despite Quebec's harsh winters.
Immediate comfort and long-term savings
From the moment it was turned on, the SHARP ZU1 heat pump provided gentle and stable warmth throughout the living space, thanks to its Coanda diffusion technology and its wide louvers with manual (horizontal) and automatic (vertical) orientation.
The owner confirmed a noticeable reduction in energy consumption compared to the previous system, and above all a constant thermal comfort, even at -20°C.
A subsidized and smart investment
This model is eligible for Hydro-Québec's LogisVert subsidies, thanks to its high energy efficiency and its ability to maintain heating down to -27°C. We assisted the client in their application to maximize their return on investment.
