A high, neat and compliant installation, for four-season comfort
At AirGreen , we prioritize smart HVAC systems that are designed to last and integrate seamlessly into Greater Montreal's residential facades. This project in Rosemont–La Petite-Patrie features a Sharp Eco Inverter wall-mounted heat pump , mounted on wall brackets under the roof overhang. The goal: to provide reliable heating and cooling while minimizing the footprint, protecting equipment from the elements, reducing vibration transmission, and maintaining easy access for maintenance.
Why a Sharp Eco Inverter wall-mounted heat pump?
Continuous modulation and efficiency
Inverter technology finely adjusts the compressor speed. The result: a stable temperature, fewer on/off cycles, reduced consumption, and very low noise levels , both in summer and winter.
A2L (R-32) refrigerant and efficiency
The unit uses low-GWP A2L (R-32) refrigerant compared to R-410A, improving seasonal efficiency and making it easier to achieve energy-saving targets. Our team follows specific A2L safety procedures : controlled handling, adequate ventilation, and rigorous circuit sealing.
Eligibility for aid
Depending on the exact configuration and performance of the machine (Energy Star, low temperature heating), the project may be eligible for local subsidies in the greater Montreal area, Laval, Longueuil, North Shore and South Shore . We support our clients in verifying the criteria and preparing the files.
Design and installation: optimized wall installation
Anchoring on brackets at height
-
Robust brackets with reinforcing plate, fixed in the masonry.
-
Visible anti-vibration wedges under the frame to limit transmission to the wall and floor of the balcony.
-
Clearances respected around the battery to guarantee air intake and avoid air recycling under the soffit.
This choice frees up floor space, protects the unit from accumulated snow and shock, and reduces exposure to garden dust and dirt.
Compact and protected refrigerated path
-
Insulated service loop to absorb expansion and allow maintenance operations.
-
Tight and neat wall penetration, with continuous insulation to avoid thermal bridges and condensation.
-
Short connection length , favorable to efficiency and refrigerant charge.
Power supply and electrical safety
-
External disconnect switch installed within easy reach of the technician.
-
Dedicated circuit from the main panel, rating and protection in accordance with manufacturer specifications and current standards.
-
Grounding checked and clear marking for intervention.
Commissioning details that make the difference
Meticulous procedures
-
Deep vacuum (up to 500 microns) with stabilization to ensure the absence of moisture and air.
-
Nitrogen leak test , followed by pressure observation.
-
Check the tightening torques of the flared fittings and apply A2L compatible oil if necessary.
-
Control of intensities , insufflation temperatures and return to confirm actual performance.
Defrosting and condensate management
Installing the system high up, under the soffit, limits snow burial and facilitates the flow of defrost water. We validate the drip path to prevent any runoff onto steps, coverings, or passageways.
Context of the house and constraints addressed
Painted brick facade, covered balcony
The site features painted brick cladding and a covered balcony. We have:
-
Position the condenser under the overhang to protect it from direct precipitation while respecting air clearances.
-
Use anchors suitable for masonry , with appropriate sealing, to avoid micro-cracks and ensure long-term strength.
-
Provided clear access from below the unit for seasonal operations (cleaning the battery, checking connections).
Vibration and noise management
In addition to the anti-vibration pads, the alignment of the brackets and the perfect squareness of the chassis limit resonances. The inverter modulation maintains a low noise level in stabilized mode, a significant advantage for busy balconies and neighbors.
Sizing and usage tips
Capacity and comfort
For a typical living area, the capacity chosen is generally around 12,000 to 18,000 BTU/h , depending on the load calculation (orientation, insulation, windows). We systematically carry out a thermal assessment in order to adapt the size of the unit to the reality of the housing.
Best practices
-
Keep the area around the unit clear (no objects stored under the platform).
-
Clean the outdoor battery in early spring and after the pollen season.
-
In winter, visually check that drifted snow is not accumulating against the condenser.
-
Schedule periodic maintenance: checking parameters, tightening, cleaning internal filters.
Result: stable comfort and preserved facade
This high-mounted Sharp heat pump installation combines discretion and performance. The client benefits from consistent comfort throughout the seasons, controlled energy consumption , and equipment protected from the elements. The installation complies with industry standards while enhancing the architecture of the Rosemont–La Petite-Patrie property.
