A high-end heating and cooling solution, professionally installed by AirGreen in Varennes
At AirGreen, we put our expertise to work for families in Varennes, on the South Shore of Montreal, by offering HVAC (heating, ventilation, and air conditioning) solutions that are sustainable, high-performing, and perfectly adapted to the harsh Quebec winters. In this project, our team completed the installation of a SHARP ZU1 18,000 BTU wall-mounted heat pump, a unit known for its energy efficiency and solid performance in extreme cold.
Installation context in Varennes
Located in a residential neighborhood of Varennes, this project aimed to modernize the heating and cooling system of a single-family home. The client was looking for a high-performance, low-impact environmental solution that could provide excellent year-round thermal comfort—even during intense cold spells.
We recommended the SHARP ZU1 18,000 BTU wall-mounted heat pump, which combines cutting-edge Japanese technology, low energy consumption, and proven reliability. With optimal performance down to -27°C, it’s an excellent fit for the climate in Greater Montreal.
Why choose the SHARP ZU1 heat pump?
Outstanding energy performance
The SHARP ZU1 18,000 BTU runs on R32 refrigerant, known for its low global warming potential (GWP), and delivers impressive performance metrics:
-
SEER: 24 (cooling)
-
HSPF IV: 13 / HSPF V: 10 (heating)
-
Heating capacity up to 21,600 BTU
-
Heating maintained even at -27°C: up to 11,500 BTU
Quiet and discreet
This unit operates remarkably quietly, with indoor noise levels as low as 25 dB. Perfect for residential use, even near bedrooms.
Exclusive Plasmacluster Technology
The ZU1 series features Plasmacluster Technology, a SHARP-exclusive innovation that purifies indoor air by releasing positive and negative ions. It neutralizes viruses, bacteria, mold, and odors, creating a healthier indoor environment.
Designed for the Quebec climate
Thanks to the patented Hot Gas Pipe system, the ZU1 prevents ice buildup in the drain pan and maintains optimal heating performance—even during extreme cold. This feature is essential for our clients in Varennes, Montreal, Laval, and Longueuil.
Technical installation details by AirGreen
Strategic placement of the compressor
We installed the outdoor unit on a galvanized steel wall bracket, elevated from the ground to prevent obstruction from snow buildup in winter. The brick wall offered a solid base, and our team reinforced the mounts for maximum stability.
Line set and conduit protection
The refrigerant and electrical lines were carefully protected using a powder-coated line cover in brick color, ensuring aesthetic integration with the building and shielding the lines from weather exposure.
Optimized indoor configuration
The indoor unit was installed in a central living area, ensuring even distribution of warm and cool air thanks to the unit’s adjustable airflow feature. The Coanda effect allows air to gently flow along walls and ceilings to avoid direct drafts on occupants.
LogisVert Hydro-Québec Grant and long-term savings
This model is eligible for Hydro-Québec’s LogisVert grant, offering up to $1,704 depending on the home's specifics. Additionally, its superior energy efficiency helps the client significantly reduce their annual electricity bill.
Technical challenges successfully handled
-
Winter access: The installation was completed despite challenging winter conditions, with professional snow clearing and meticulous site prep.
-
Preserving the brick façade: We drilled using specialized tools to avoid any cracking or moisture infiltration.
-
Perfect conduit slope: Our team took care to calibrate the slope of the lines to ensure optimal drainage of condensate, a detail often overlooked by less experienced installers.
Why trust AirGreen?
At AirGreen, we don’t just sell and install HVAC systems. We provide personalized support, from model selection to system startup, including a full explanation of how it works and available grant programs.
Our certified installers follow the industry’s strictest standards and are thoroughly familiar with the specific features of SHARP units, including their unique Plasmacluster technology.
Final outcome: immediate and lasting comfort
At the end of the installation, the Varennes client immediately noticed:
-
Better temperature control throughout the home
-
Exceptionally quiet operation
-
Improved indoor air quality
-
Expected reductions in energy consumption
This project is yet another example of our ability to deliver high-quality installations, tailored for the Quebec climate, while respecting both timelines and budget.
