Optimized comfort and energy efficiency in the heart of downtown Montreal
Located in the heart of Ville-Marie, this AirGreen installation perfectly illustrates our expertise in high-end residential HVAC systems . In an elegant downtown condo with a panoramic terrace, our team installed a Sharp ZHU1 wall-mounted heat pump —a model renowned for its exceptional low-temperature performance and its more environmentally friendly R-32 refrigerant technology .
A thoughtful choice for Montreal's climate
The client wanted a compact, quiet, and efficient solution that would provide consistent comfort year-round , even during the harsh Montreal winters. The Sharp ZHU1 was a natural choice thanks to its heating capacity down to -25°C and its high-efficiency inverter compressor . This model combines energy savings , thermal stability , and a discreet design —qualities that are particularly sought after in high-density urban buildings.
Technical details and installation configuration
The outdoor unit, securely mounted on a galvanized aluminum support above the ground, ensures perfect stability and optimal air circulation. This configuration prevents snow accumulation and facilitates seasonal maintenance.
The refrigerant and electrical connections have been carefully concealed under white capping matching the facade , guaranteeing harmonious visual integration.
The installation benefits from optimized gravity drainage , eliminating the need for a condensate pump. Everything was connected to a dedicated power supply with an independent circuit breaker, in accordance with RBQ and CSA standards .
An intervention adapted to the urban environment
Working in a high-rise condo in the Ville-Marie sector requires specific logistics: transport of equipment by service elevator, restricted access to the balcony, and strict compliance with co-ownership regulations.
Our technicians planned each step to minimize noise and visual disturbances, completing the work in a single day, while ensuring a complete leak check and a nitrogen pressure test before commissioning.
Result: performance and elegance
The end result provides the customer with a discreet, quiet, and energy-efficient system . The Sharp ZHU1 provides stable heating, rapid cooling, and precise indoor temperature control.
Thanks to its R-32 refrigerant, the system reduces global warming potential by 68% compared to older R-410A models.
Everything is compatible with provincial subsidy programs such as Chauffez vert and Transition énergétique Québec , allowing the owner to benefit from a rapid return on investment.
