Optimized performance for Québec winters in a tight urban space
In the vibrant Ahuntsic-Cartierville neighbourhood, in the heart of Montréal, we recently completed the installation of a SHARP ZU1 18000 BTU wall-mounted heat pump, a perfect solution for year-round heating and cooling needs in urban homes. This project highlights the rigorous and personalized approach we take at AirGreen for all our HVAC residential installations.
Why choose the SHARP ZU1 18000 BTU model?
The SHARP ZU1 is known for its energy efficiency, resilience in northern climates, and integrated Plasmacluster technology. This model, powered by the eco-friendly R-32 refrigerant, not only helps to reduce the home’s carbon footprint, but also delivers excellent performance in all seasons.
Key technical specifications:
-
Heating capacity: up to 21,800 BTU/h
-
Cooling capacity: 18,000 BTU/h
-
Energy efficiency: SEER of 24 and HSPF up to 13
-
Heating operating range: down to -27 °C
-
Plasmacluster technology: purifies indoor air by eliminating mold, viruses, and allergens
-
Refrigerant: R-32 (environmentally responsible)
-
AHRI & ENERGY STAR certified
-
Eligible for grants such as the Hydro-Québec LogisVert program
A space-constrained installation handled with precision
This unit was installed in a service area under a balcony, a common setup in Montréal homes where maximizing space is key. We used a raised galvanized aluminum stand to support the outdoor unit, ensuring optimal airflow while protecting the unit from moisture and snow accumulation.
Installation details:
-
Secured on concrete slab for stability and durability
-
Tight, insulated refrigerant line routing with reinforced insulation
-
Discreet integration of the electrical box for safe power connection
-
Optimal unit placement to avoid direct exposure to exhaust air or runoff
Indoor comfort, air purification, and energy savings
SHARP’s exclusive Plasmacluster technology works continuously to purify the air, neutralizing bacteria, viruses, and mold. This ion system recreates the natural conditions of fresh air while ensuring a healthier environment for the whole family.
In addition, thanks to the smart modulation of the high-performance inverter compressor, the indoor temperature remains consistent without sudden energy spikes, which translates into significant savings on electricity bills.
Client testimonial: performance and peace of mind
The homeowner told us that during last winter, despite temperatures dropping to -20 °C, the SHARP ZU1 continued to heat the house efficiently without triggering the auxiliary system. The quiet operation of the indoor unit was also highly appreciated, especially at night.
"I’m impressed by the consistent temperature and the air quality since the installation. You can literally feel the difference. And absolutely no disturbing noise!"
