A carefully executed balcony installation project in an urban environment
At AirGreen, we know that every wall-mounted heat pump installation is unique, and that the environment in which we work directly influences the complexity of the project. In the dynamic and residential neighborhood of Hochelaga in Montreal, we recently installed a SHARP ZU1 12,000 BTU heat pump, an ideal unit for small to medium-sized apartments and condos. This project perfectly illustrates our tailored approach and our ability to work in tight urban settings while ensuring performance, durability, and aesthetics.
Installation context: a narrow balcony and limited space
The outdoor unit was installed on a private balcony with very limited space, typical of multi-unit buildings in Hochelaga. To ensure optimal air circulation, impeccable stability, and protection against vibrations, we installed the unit on a raised aluminum structure, designed to maximize the system’s longevity while respecting space constraints.
The main challenge of this installation was the precise positioning of the outdoor unit to meet the client’s requirements, municipal regulations, and the minimum distance needed for efficient and quiet operation.
Focus on the SHARP ZU1 – 12,000 BTU heat pump: technology and energy efficiency
Japanese technology designed for Quebec’s climate
The SHARP ZU1 12,000 BTU, powered by R32 refrigerant, is a ductless wall-mounted heat pump specially designed for extreme northern climates. Its heating capacity is maintained down to -27 °C, making it a perfect choice for Montreal’s harsh winters.
It offers remarkable energy efficiency with a SEER of 22 and an HSPF (IV) of 12.5, allowing occupants to achieve significant savings on their annual electricity bills—all without compromising comfort.
Plasmacluster: continuously purified air
One of the major advantages of this heat pump is its exclusive Plasmacluster technology from SHARP, integrated into all models of the ZU series. This system purifies the ambient air by generating positive and negative ions capable of eliminating mold, allergens, viruses, and unpleasant odors. A real benefit for urban apartments where indoor air quality is essential.

Key installation steps by AirGreen
1. Site inspection
Our team conducted a comprehensive balcony inspection, taking into account regulatory clearances, feasibility of duct routing, and optimal orientation to avoid any hot air discharge toward neighbors.
2. Custom raised support
To avoid direct contact with the balcony floor and allow proper drainage, we designed a custom anti-corrosion metal support. This also protects the unit from snow accumulation in winter.
3. Duct passage
We precisely drilled the exterior wall without damaging the interior finish of the dwelling, and insulated the duct passage to prevent any thermal loss and infiltration of air or moisture.
4. Electrical connection and commissioning
Our master electrician completed the full electrical connection in compliance with safety standards, followed by a complete commissioning of the unit: pressure checks, performance tests, and remote control calibration.
Benefits for the Hochelaga resident client
The installation of this SHARP ZU1 12,000 BTU wall-mounted heat pump has transformed the client’s thermal experience. Here is the direct feedback:
-
Stable and consistent temperature all year round
-
Reduction in monthly energy bills
-
Improved acoustic comfort (thanks to the low noise level of the indoor unit)
-
Healthier and more pleasant air to breathe, thanks to active Plasmacluster purification
Available subsidies: an even more profitable investment
The SHARP ZU1 heat pump is eligible for government subsidies, notably through the Hydro-Québec LogisVert program, which can reach up to $2,172 depending on the configuration and type of dwelling. At AirGreen, we help our clients prepare and submit their subsidy applications, simplifying the entire administrative process.
