Installation of a Sharp Eco Inverter wall-mounted heat pump in Rosemont–La Petite-Patrie
AirGreen installs a Sharp Eco Inverter wall-mounted heat pump in Rosemont–La Petite-Patrie. A high-performance and aesthetic HVAC solution for Montreal, Laval, Longueuil, the North Shore, and the South Shore.

In summer, the outdoor unit rejects the house's heat outside.

Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
An energy-efficient upgrade in the heart of a Montreal brick duplex
At AirGreen , we regularly work in Montreal's central neighborhoods where brick homes and duplexes, built in the mid-20th century, require modern heating and cooling solutions. This project in Rosemont–La Petite-Patrie perfectly illustrates how a Sharp Eco Inverter wall-mounted heat pump can transform the comfort of a home while respecting the original architecture.
The installation took place on the side façade of a typical red brick residence, with limited floor space and neighborhood constraints. Through careful planning, our team optimized the integration of the outdoor unit without compromising aesthetics or energy efficiency.
Sharp Eco Inverter Heat Pump Features
The Sharp Eco Inverter range is designed to provide stable performance in all seasons, particularly suited to the climates of Greater Montreal.
Technical highlights:
-
Available capacity : from 9,000 to 18,000 BTU, covering a wide range of residential needs.
-
Inverter technology : intelligent power adjustment for increased efficiency.
-
Energy performance : high SEER and HSPF coefficients, allowing significant reduction in electricity consumption.
-
Grant compatibility : eligible for provincial and federal programs, notably thanks to its Energy Star certification.
-
Quiet operation : both inside and out, a key factor in dense neighborhoods like Rosemont.
Installation process
Preparation and exterior fixing
The outdoor unit has been securely mounted on galvanized wall brackets to raise it off the ground. This arrangement protects the system from moisture, debris, and snow accumulation in winter.
Discreet integration
The electrical wiring and refrigerant lines were carefully routed within a protective cover colored to match the brickwork and existing downspout. This aesthetic consideration is essential in a neighborhood where brick facades are visible from the street.
Drainage management
Thanks to a slight natural slope and a well-chosen location, condensate drainage is carried out by gravity, thus avoiding the need for a pump. A simple, reliable solution with no additional maintenance.
Constraints and solutions provided
Limited space
The installation was to be done between a downspout and a basement window. Our team carefully positioned the condenser to maintain safety clearances while optimizing airflow.
Power supply
The house's electrical panel was located nearby, allowing for quick and secure connection via an exterior service box. This reduces installation costs and ensures easy access for future maintenance.
Results and benefits for the client
Since commissioning, occupants have benefited from:
-
Four-season comfort : air conditioning in summer and efficient heating in winter.
-
Reduced energy bills , thanks to the high efficiency of Inverter technology.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
