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 efficiency project in a Montreal condo
At AirGreen , we recently completed the installation of a Sharp wall-mounted heat pump in a condo in the Rosemont–La Petite-Patrie area of Montreal . This neighborhood, known for its modern yet traditional residential buildings, often requires HVAC solutions adapted to tight spaces and specific architectural constraints. Our client wanted to improve their comfort while reducing their energy bills. The Sharp heat pump was a wise choice, combining compactness, performance, and reliability.
Why a Sharp wall-mounted heat pump?
Sharp wall-mounted heat pumps are distinguished by their discreet design, quiet operation, and high energy efficiency. In this case, the unit installed belongs to the ZU1 series , a popular range in Greater Montreal. It offers:
-
Efficient heating capacity even during Montreal's harsh winters.
-
Efficient and constant air conditioning during humid summers.
-
Reduced energy consumption, ideal for owners looking to make their investment profitable in the medium term.
-
Eligibility for Quebec grant programs for approved devices.
The particularities of this HVAC installation
The indoor unit was mounted high up near the ceiling, just above a large window overlooking the balcony. This arrangement ensures optimal air distribution throughout the space while maximizing occupant comfort. The outdoor unit was installed on a wall mount accessible from the balcony, allowing for simplified maintenance and good air circulation around the condenser.
Among the challenges encountered:
-
Working at height on a balcony : our team used suitable safety equipment to handle the unit and make the necessary holes through the partition.
-
Condensate drainage management : gravity flow has been provided to avoid the addition of a lifting pump, which reduces future maintenance.
-
Aesthetic finishes : white capping was installed to conceal the refrigeration and electrical conduits, blending harmoniously into the interior.
Results and customer satisfaction
Upon completion of the installation, the client immediately noticed an improvement in thermal comfort in their condo. The wall-mounted Sharp heat pump now provides stable, fluctuating heating in winter and gentle cooling in summer. The quiet operation is particularly appreciated, especially in an urban environment like Rosemont.
Our approach is always to adapt the solution to the client's context. In this case, the combination of a high-performance device and careful installation guarantees optimal longevity and energy efficiency.

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.
