A comfort project by AirGreen in a typical South Shore house
At AirGreen , we recently completed a complete installation of a Zephyr wall-mounted heat pump for a single-family residence in Sainte-Julie , on the South Shore of Montreal . This project perfectly illustrates our meticulous approach and expertise in the field of residential heating, ventilation and air conditioning (HVAC) .
The context of the project
Our client wanted to upgrade their air conditioning system to reduce energy consumption and improve their comfort year-round. The old, aging wall-mounted unit was showing several signs of wear:
-
insufficient performance during heat waves;
-
increased compressor noise;
-
increasing electricity consumption.
After a complete evaluation of the residence, our technicians recommended the Zephyr wall-mounted heat pump , a model recognized for its excellent performance-price ratio and its reliability in Quebec climates .
Choosing the Zephyr model: performance and reliability
The Zephyr brand, distributed exclusively by AirGreen , has established itself as a local benchmark in terms of high-performance and durable wall-mounted heat pumps . The model chosen for this project offered:
-
a capacity of 12,000 BTU , ideal for the main rooms of the house;
-
high energy efficiency thanks to its variable speed compressor (inverter);
-
quiet operation (< 22 dB for the indoor unit);
-
a compact and elegant design , blending harmoniously into the red brick facade of the house.
Technical installation: precision and aesthetics
Our teams installed the outdoor unit on a galvanized aluminum wall bracket , securely fixed to the concrete foundation. This configuration guarantees:
-
better air circulation around the compressor;
-
increased protection against snow and moisture ;
-
long-term stability , even during spring thaw cycles.
The electrical wiring was carefully integrated into the structure, with a protective casing that complies with CSA and Hydro-Québec standards . The indoor unit was then installed in the living room, positioned to ensure optimal distribution of heat and cold.
Key project milestones
-
Site inspection : checking the load-bearing wall, distance from openings and electrical routing.
-
Preparation of the support : installation of a raised aluminum base and adjustment of the laser level.
-
Zephyr condenser mounting : installation of the outdoor unit with anti-vibration silent blocks.
-
Refrigeration connection : brazing under nitrogen and leak test at 450 psi.
-
Vacuuming and start-up : Complete evacuation of the system, then commissioning according to the manufacturer's specifications.
-
Final checks : check air flow, pressures, and operation in heating and air conditioning modes.
Result: four-season comfort
Following the installation, the customer immediately noticed:
-
a more uniform interior temperature , without drafts;
-
a significant reduction in noise compared to the old device;
-
an estimated energy saving of 30% on the annual electricity bill.
Our technicians took care to explain how the auto mode works, filter maintenance, and best practices for maintaining optimal performance all year round.
