A wall-mounted heat pump installation designed to maximize energy performance and comfort in a condo
At AirGreen, we recently completed the installation of a SHARP ZU1 12,000 BTU wall-mounted heat pump in a condominium unit in Saint-Constant, on the South Shore of Montreal. This project perfectly illustrates our expertise in residential HVAC installations on enclosed balconies, a setting that demands precision, discretion, and efficiency.
The outdoor unit was carefully installed on a raised wall bracket, optimizing space without obstructing movement on the balcony. All refrigerant, electrical, and drainage lines were discreetly routed through a clean line set cover that runs along the façade. This type of installation is not only visually seamless, but also complies with condo association standards for noise and cleanliness.
Why choose the SHARP ZU1 12,000 BTU wall-mounted heat pump?
The SHARP ZU1 series is a benchmark in compact heat pumps built for cold northern climates. The model AY-XPC12ZU / AE-X12ZU1, installed in Saint-Constant, is equipped with the latest technology to provide year-round heating and cooling, even during the harsh Québec winters.

-
Cooling capacity: 12,000 BTU/h (min-max: 2,800 - 13,600 BTU/h)
-
Heating capacity: 14,000 BTU/h (min-max: 3,200 - 17,100 BTU/h)
-
Performance in extreme cold: 7,200 BTU/h at -27°C
-
SEER / SEER2: 21 / 22 — top-tier energy efficiency
-
R32 refrigerant: eco-friendly, low GWP, high efficiency
-
Plasmacluster technology: purifies indoor air by eliminating bacteria, viruses, allergens, and mold
-
Built-in Wi-Fi control: manage settings remotely via mobile app
Unique context of this installation: a protected condo balcony
In Saint-Constant, the unit was installed on a covered balcony, exposed to seasonal temperature fluctuations, but protected from direct weather. This provides added protection for the outdoor unit while ensuring proper condensate drainage thanks to SHARP’s advanced defrosting and piping systems.
The AirGreen team:
-
Mounted the wall bracket using galvanized steel supports suited to the space constraints
-
Ran refrigerant and electrical lines inside a rigid white wall-mounted line cover that blends seamlessly with the exterior
-
Insulated all piping with high-performance materials to prevent energy loss
-
Verified the unit’s acoustic levels to ensure it meets condo noise regulations
-
Provided the client with a full tutorial on using the SHARP mobile app and tips for routine maintenance
The exclusive benefits of SHARP’s Plasmacluster technology
SHARP’s Plasmacluster technology doesn’t just heat or cool — it actively purifies the air in your home.
It effectively combats:
-
Airborne viruses and bacteria
-
Adherent mold on walls and ceilings
-
Common household allergens (dust, dust mites)
-
Lingering odors, like cooking smells or tobacco smoke
Using a unique system of positive and negative ions, it replicates the natural purification processes found in mountain air — without the use of chemicals or artificial fragrances.
A system that perfectly fits the needs of condo families
The client in Saint-Constant reached out to us to replace an old auxiliary system that no longer met their comfort needs. The challenge was to offer a solution that was discreet, high-performing, and compatible with both the physical and administrative requirements of the condo board.
Our experts were able to:
-
Secure condo board approval by providing full technical specs and certified noise levels
-
Propose a clean, aesthetic installation design that respected the building’s visual harmony
-
Complete the installation in a single day, including full system testing, calibration, and purging
Eligibility for grants
Although Hydro-Québec’s LogisVert grants generally target heat pumps with an HSPF rating of 10 or higher, this model achieves an HSPF of 12.5 (Zone IV) and could qualify depending on the home’s configuration and current program rules. AirGreen always helps clients verify their eligibility and submit their applications.
