Installation of a Sharp Eco Inverter wall-mounted heat pump in Rosemont–La Petite-Patrie

Two outdoor units on wall brackets for four-season comfort

In a brick building in Rosemont–La Petite-Patrie , we installed two Sharp Eco Inverter wall-mounted heat pumps . The goal: to provide independentheating and cooling for two units/zonings, while preserving the aesthetics of the facade and circulation in a narrow driveway. The outdoor units are mounted on galvanized brackets at strategic heights, with clearances optimized for airflow and maintenance. The refrigeration lines run neatly in a rigid cover along the wall, then descend vertically to sealed holes.

Client context and needs

• Residential masonry building, rear driveway limited for traffic and snow removal.

• Request for two autonomous zones to separately manage the temperature of two apartments/living areas.

• Priorities: silence , reliability in Montreal winters, discreet HVAC installation respecting local and co-ownership regulations.

Why the Sharp Eco Inverter range?

Sharp is known for its sophisticated electronics and stable inverter compressors. In this project, the Eco Inverter range provides:

• Fine power modulation to maintain temperature smoothly.

• Very good seasonal heating and cooling efficiency , favorable to energy savings.

• Protected electronic cards and design thought out for service, an asset in the climate of Greater Montreal .

• Compatibility with grant program requirements when configurations meet current efficiency criteria.

Sizing and technical approach

Before proposing a tonnage, we perform a load calculation taking into account the surface area, orientation, insulation, and air infiltration. For this type of application, typical power outputs range from 9,000 to 18,000 BTU per zone, depending on actual needs. The two systems are independent : each outdoor unit powers its dedicated indoor head, simplifying control and maintenance.

Salient installation details

• Mounting : Robust galvanized steel wall brackets, anchored to the brick with suitable sealing. The chosen height places the machines above snow and dirt, while reducing the unevenness of the asphalt.

• Vibration management : anti-vibration pads under the frames and controlled tightening to prevent transmission to the brick facing.

• Refrigeration path : horizontal paths under rigid UV cover, then clean vertical descent ; bending radius respected to preserve the integrity of the copper.

• Drilling : precise coring with slope for flow and closed vapor barrier (sealing return) to avoid any thermal bridge or infiltration.

• Electrical : Power supply on dedicated circuit breakers and disconnect boxes near maintenance, in accordance with RBQ/CSA standards.

• Condensate drainage : gravity drainage preferred when possible; otherwise, sized and insulated condensate pump (here, gravity sufficient thanks to the slope and height of the brackets).

• Clearances : free space at the front and sides to ensure air flow and winter defrosting ; center distance studied between the two machines to avoid recirculation.

Construction site challenges… and our solutions

1. Narrow aisle and traffic : the wall bracket option frees up the floor and protects the units from impacts (garbage cans, snow plow).

2. Brick facade : suitable anchors, careful sealing and restoration of the facing for a clean and durable finish.

3. Noise management : fan orientation and height calculated to limit sound reflection on the opposite wall; sound levels checked in reduced operation using the inverter.

4. Montreal winter : installation protected from falling ice and sufficient height to keep the grid out of snow banks ; advice for use during storms.

Result: two comfortable and autonomous areas

Each occupant has their own thermostat and remote control to precisely adjust the temperature. The inverter maintains stable settings, reducing electricity costs and the feeling of drafts. In summer, the air conditioning keeps rooms dry; in mid-season and winter, the heat pump provides efficient heating at controlled operating costs.

Good practices for use and maintenance

• Filters : Clean the filters of the interior heads every 4 to 8 weeks depending on use.

• Winter defrosting : allow the units to work freely; do not obstruct the grilles with objects or snow drifts.

• Annual HVAC maintenance **: pressure inspection, electrical test, support and drainage check; this preventive visit extends the lifespan and preserves performance.

• Programming : favor stable setpoints rather than significant deviations so that the inverter can do its optimization work.

Grants and Compliance

When the configurations and performance meet current criteria, these wall-mounted heat pumps may be eligible for provincial and municipal incentives . We guide our customers through the required procedures, installation certificates , and technical documents , whether you are in Montreal, Laval, Longueuil, on the North Shore, or the South Shore .

What sets AirGreen apart in this type of project?

• On-site study and transparent recommendations (single unit vs. multi-zone, power, layout).

• Neat finish : aligned hood, clean seals, secure wiring, clearances respected.

• Respecting deadlines : coordination with condominiums and planning to minimize the impact on residents.

• After-sales service : parts availability, team of HVAC technicians trained in Sharp ranges and other brands served by AirGreen.

Tips for a masonry building in Rosemont

• Use brackets when the driveway is narrow or subject to snow removal.

• Maintain an aesthetic line : aligned hoods, colors coordinated with the facing.

• Check electrical capacity and sufficient clearance around units.

• Anticipate maintenance : clear access to disconnections and underside of machine for drainage inspection.

Conclusion

This Sharp Eco Inverter installation in Rosemont–La Petite-Patrie demonstrates our approach: precise analysis , clean integration , and sustainable performance . Two independent wall systems deliver controlled comfort, attractive energy efficiency , and a finish that enhances the building.
