A neat installation on the terrace for four-season comfort by AirGreen
At AirGreen , every wall-mounted heat pump installation project is carefully considered to ensure optimal operation and perfect aesthetic integration into the residential environment. This project in Lachine , on a terrace typical of modern buildings in the area, perfectly illustrates our expertise in sustainable and safe HVAC installation.
Project background
The client wanted an energy-efficient solution to replace an aging air conditioning system. After analyzing the home's layout and heating needs, we recommended installing a Sharp ZU1 , a wall-mounted heat pump that uses R-32 refrigerant , known for its stable performance down to -25°C and superior energy efficiency (Energy Star).
The main challenge: ensuring a quiet , safe and weather-resistant installation, while maintaining easy access for maintenance.
Technical details of the installation
-
Equipment type: Sharp ZU1 wall-mounted heat pump
-
Capacity: 18,000 BTU
-
Refrigerant: R-32 (class A2L, low environmental impact)
-
Support: Mounting on sturdy galvanized wall brackets
-
Condensate drainage: Gravity-fed, sheathed and insulated to prevent freezing
-
Electrical connection: Wall-mounted protective box with discreet wiring
-
Finish: Wiring and piping sheathed in white capping perfectly aligned with the wall covering
The outdoor unit was precisely positioned on a concrete side wall , ensuring excellent stability and sufficient clearance for rear ventilation. The installation height also helps prevent snow accumulation in winter, a key factor in the durability of HVAC systems in Montreal.
Why the Sharp ZU1 is an ideal choice for Montreal
The Sharp ZU1 series stands out for its inverter compressor technology and its ability to provide consistent comfort, even in the extreme cold of the metropolitan area. Its quiet operation and compact design make it a preferred option for condos , plexes and townhouses .
This heat pump is also eligible for government subsidies for high-efficiency systems, particularly as part of residential electrification programs.
A durable and aesthetic installation
On this project in Lachine, our team paid particular attention to the cleanliness of the wiring , the strength of the fasteners and optimal air circulation . The result: a high-performance system, both discreet and integrated into the building's architecture.
Thanks to our expertise, this installation combines:
-
Exceptional energy performance in all seasons,
-
Visual discretion on the terrace,
-
Long-term reliability with corrosion-resistant components,
-
And simplified maintenance thanks to clear and safe access.
