An AirGreen Installation in Saint-Lambert, Combining Energy Efficiency, Purified Air and Optimal Comfort
As part of our recent residential projects in the South Shore, we had the opportunity to install a SHARP ZU1 12000 BTU wall-mounted heat pump in a home located in Saint-Lambert, a city known for its architectural charm and the high expectations of its residents when it comes to indoor comfort. This installation is part of our commitment to providing high-quality HVAC (heating, ventilation and air conditioning) solutions to residents of Montréal, Laval, Longueuil, the North Shore and the South Shore.
Why Choose the SHARP ZU1 Series?
Performance Built for Quebec’s Climate
The SHARP ZU1 12000 BTU model, powered by R32 refrigerant, is engineered to meet the demanding climate of Quebec, with a heating capacity of up to 7,200 BTU/h at -27 °C. This feature is essential in a region like Saint-Lambert, where winter temperatures can be particularly extreme.
Plasmacluster Technology – Built-In Air Purification
Exclusive to SHARP, Plasmacluster technology is built into all ZU1 units. It generates positive and negative ions to neutralize viruses, bacteria, mold and allergens, while also significantly reducing odours (tobacco, pets, cooking). In a residential context, this represents a significant advantage for families concerned about their indoor air quality.
Compact Unit with Sleek Design
The outdoor unit shown in the photo was installed on an elevated aluminum stand, securely anchored to a concrete slab. This setup allows for optimal drainage and protects against snow or water buildup. With a total weight of 30 kg and compact dimensions (30 23/32" x 21 1/4" x 10 19/32"), the system integrates seamlessly with the architectural surroundings of the home.

Installation Details in Saint-Lambert
Initial Assessment and Customer Needs
The homeowner was looking to replace their old wall-mounted air conditioner with a more efficient heating system, in order to reduce reliance on electric heating while improving indoor air quality. After a full thermal evaluation, we recommended the SHARP ZU1 12000 BTU model, perfectly suited for the size of the ground floor.
Preparation and Setup
-
Strategic placement: The indoor unit was positioned in a central open-concept area to ensure even air distribution. The outdoor unit was installed in the backyard, positioned away from prevailing winds for enhanced performance.
-
Raised base: The AirGreen team poured a reinforced concrete slab, then installed a galvanized aluminum support frame to elevate the outdoor unit, preventing any buildup of water, ice or snow.
-
Drilling and connections: We drilled through the load-bearing wall with precision to route the refrigeration lines (1/4 x 3/8 in.) as well as the electrical connections.
Commissioning and Testing
Once the installation was complete, we:
-
Tested the system in both cooling and heating modes.
-
Checked for tight connections and refrigerant leaks.
-
Measured air output, sound levels and real-time power usage.
-
Programmed the energy-saving modes via the wall-mounted remote control.
Benefits for the Client
