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.
A careful installation for lasting comfort in a Laval duplex
At AirGreen , we recently installed a Sharp Eco Inverter wall-mounted heat pump in a duplex in the Chomedey area of Laval . This residential neighborhood perfectly combines comfortable living and proximity to services, making it an ideal location for energy modernization projects. Our client wanted an energy-efficient and quiet system that could maintain a stable temperature throughout the year, even during harsh Quebec winters.
Choosing the Sharp Eco Inverter model
The Sharp Eco Inverter is a high-performance wall-mounted heat pump that uses Plasmacluster Ion technology to purify the ambient air while ensuring efficient heating and cooling. Thanks to its frequency-reversing compressor (inverter) , this model automatically adjusts its power according to demand, thus optimizing electricity consumption.
Key benefits of this model include:
-
High energy efficiency , reducing electricity bill;
-
Quiet operation , ideal for urban environments;
-
Plasmacluster air purification technology , contributing to a healthier indoor environment;
-
Operating capacity down to −25°C , perfectly suited to the climate of Greater Montreal.
Technical details of the installation
For this installation, our team secured the outdoor unit to a side brick wall using sturdy galvanized steel brackets , ensuring long-term stability. The unit is mounted at a safe height above the ground, preventing snow buildup and promoting good airflow around the compressor.
The refrigeration pipes and electrical wiring have been carefully protected by discreet beige capping , ensuring a clean and durable finish. Condensate is drained by gravity , avoiding the need for an additional pump and thus reducing the risk of future maintenance.
A residential environment typical of Greater Montreal
The Chomedey duplex features a classic Laval neighborhood setting: exterior metal stairs, red brick facades, and semi-open spaces . This type of architecture often requires a compact and discreet installation , without compromising the aesthetics of the property. Thanks to the compactness of the Sharp heat pump , we were able to install the unit without obstructing passageways or compromising the strength of the structure.
A performance and sustainability-oriented approach
Each AirGreen installation is based on three principles: efficiency, safety and sustainability .
-
Prior to installation, we performed a heat load assessment to confirm the required capacity (BTU) for this home.
-
The electrical wiring was connected to a dedicated and protected power supply , in accordance with the standards of the Canadian Electrical Code.
-
The orientation of the unit was chosen to minimize direct exposure to sun and wind , extending the life of the compressor.
Energy savings and possible subsidies
Sharp Eco Inverter heat pumps are among the models eligible for Hydro-Québec and Quebec government grant programs , particularly through Rénoclimat . This financial assistance allows Laval homeowners to recoup their investment more quickly while reducing their carbon footprint.
Customer satisfaction guaranteed by AirGreen
The owner of the duplex highlighted the speed and cleanliness of our intervention. In just one day, his air conditioning and heating system was fully operational , providing immediate comfort and a significant reduction in ambient noise compared to his previous unit.
At AirGreen, we support our customers every step of the way: from model selection and installation planning to maintenance advice and after-sales support . This personalized approach ensures optimal performance and lasting peace of mind.

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.
