Four-season comfort, discreet installation and performance designed for Montreal plexes
Background and objectives
At AirGreen , we are working today in a typical Rosemont–La Petite-Patrie apartment. The client is looking for a reliable, quiet, and economical heating and cooling solution for their main living area, with a compact and clean installation . We offer a Zephyr wall-mounted heat pump , ideal for Montreal homes where space and aesthetics matter as much as performance.
Equipment Choice: Why Zephyr for this Project
-
Reliable and quiet : the Zephyr indoor head features a sleek front and discreet display, making it ideal for living rooms.
-
Energy efficiency : the recent Zephyr wall-mounted ranges offer high heating and air conditioning efficiency, a major asset for reducing operating costs in Montreal .
-
Uniform comfort : wide motorized shutter for regular airflow, limiting cold areas.
-
Simplified maintenance : easily accessible filters for quick HVAC maintenance by our teams or by the owner.
Salient installation details
-
Location : Installed in the upper part of a load-bearing wall facing outwards. This configuration allows for a short cooling path and limits pressure losses.
-
Wall Pass-Through : Single 2–3 inch drilling, direct rear exit; minimal interior capping and white finish to blend into the wall.
-
Condensate drainage : gravity drain with continuous slope towards the outside, avoiding the use of a pump and reducing maintenance.
-
Power supply : dedicated circuit protected at the panel, in accordance with the Quebec Construction Code; interconnection and communication cable passed with the refrigerant lines for a clean finish.
-
Anti-vibration and acoustics : interposition of anti-vibration pads and verification of tightening in order to maintain a very low noise level in the room.
-
Commissioning : deep vacuum, leak test, service opening, parameter check (blowing temperature, intensity, superheat/subcooling) and calibration of the flaps to direct air away from the seating areas.
Sizing and usage advice
Proper sizing is crucial for comfort and economy. In Rosemont's plexes, open-plan living spaces often require moderate power, but this is supported by high efficiency at low temperatures. We check:
-
internal volumes and contributions (kitchen, solar exposure),
-
real insulation (brick walls, windows),
-
air circulation between rooms.
Tips : Keep the heat pump in heating mode continuously during cold weather, avoid frequent changes to the setting, and clean the filters every 6 to 8 weeks.
Result: immediate comfort and neat aesthetics
The client benefits from a wall-mounted air conditioner/heat pump with very discreet integration: white front, soft central display , no visible cables. The airflow covers the living area without direct draft, with a significant drop in humidity in summer and rapid heating in the off-season.
Grants and Compliance
Depending on the version chosen and its seasonal performance , the Zephyr wall-mounted heat pump may be eligible for provincial grant programs when the efficiency and cold weather performance criteria are met. We validate eligibility on a case-by-case basis, prepare the documents and accompany the customer until the deposit.
AirGreen Preventive Maintenance
To maintain performance:
-
cleaning of exchangers and fans,
-
drain and slope check,
-
checking electrical connections and tightening torque,
-
inspection of the refrigeration cycle and updating of parameters.
We recommend an annual visit before the cold season. Proper maintenance extends the lifespan and maintains yields .
Best practices for installation in Greater Montreal
-
The shortest possible route to the outside to reduce losses and accelerate the evacuation of condensates.
-
Waterproof penetration with vapor barrier and clean finish, essential in brick walls of plexes.
-
Noise management : position the head to avoid direct blowing on the seating areas and limit resonances.
-
Exterior winter protection (at the condenser): compliant clearances, snow and ice management, retention tank if necessary.
