Four-season comfort perfectly integrated into Montreal architecture
At AirGreen , we recently installed Zephyr R-32 wall-mounted heat pumps in a typical duplex in Rosemont–La Petite-Patrie , an iconic residential neighborhood in Montreal. This project perfectly illustrates our expertise in integrating efficient HVAC solutions into brick buildings with metal balconies—without compromising aesthetics or energy performance.
The context of the project: modernizing comfort without altering the charm of a plex
The owners wanted to replace their old air conditioners with an energy-efficient four-season system capable of providing heating in the winter and cooling in the summer , while respecting the building's structure. Their priorities were clear:
-
Reduce annual energy bills;
-
Enjoy durable and quiet equipment;
-
Maintain a discreet exterior installation, suited to the red brick facade.
Choosing the Zephyr R-32 heat pump: efficiency, reliability and respect for the environment
The Zephyr R-32 range was chosen for its environmentally friendly R-32 refrigerant technology , recognized for its stable performance down to −25°C , an essential criterion in Montreal.
These models are also distinguished by:
-
High energy efficiency (up to 22 SEER);
-
A rapid and constant heating function even in very cold weather;
-
A compact design ideal for urban facades;
-
Compatibility with Quebec subsidies related to energy efficiency.
The particularities of the installation in Rosemont
Our team installed two Zephyr outdoor units , securely mounted on galvanized wall brackets . This configuration optimizes air circulation while preventing any accumulation of snow on the ground.
Key installation steps:
-
Study of the refrigeration route to guarantee a minimal and aesthetic route;
-
Fixing the wall brackets with anchors suitable for brick;
-
Refrigerant pipes pass through a discreet brown capping , matching the facade;
-
Electrical connection to a dedicated service box;
-
Pressure and energy performance tests before commissioning.
The refrigerant connections were insulated to withstand temperature variations, while gravity drainage was installed to prevent any water stagnation or winter freezing.
A harmonious and lasting integration
The two units, perfectly aligned under the rear windows, ensure a balanced distribution of comfort between the two dwellings of the duplex. The whole remains aesthetically sober and easily accessible for HVAC maintenance .
The result: an installation that is clean, quiet and efficient , meeting the strictest safety and efficiency standards.
Performance and customer satisfaction
From the first commissioning, the occupants noticed a significant improvement in thermal comfort :
-
Rapid cooling of main parts;
-
Constant heating even on cold February nights;
-
Significant reduction in electricity consumption compared to their old system.
All this with an almost imperceptible noise level , proof of the design quality of the Zephyr units.
Maintenance and durability
At AirGreen , we remind our customers that regular maintenance is the key to long-lasting performance. Annual cleaning of the internal filters , along with checking the refrigerant level and drainage , guarantees these heat pumps a longevity of more than 15 years .
We also offer a complete preventative maintenance program to maintain the optimal performance of each Zephyr system installed in Montreal, Laval, Longueuil and on the North and South shores.
AirGreen: expertise, precision and commitment
This installation perfectly illustrates our approach: tailor-made HVAC solutions, adapted to Montreal's buildings . Every detail—from the choice of support to cable management—is designed to combine efficiency, aesthetics, and durability.
Our mission remains unchanged: to offer residents of Greater Montreal reliable, energy-efficient and accessible comfort , through professional installations by AirGreen.
