In the quiet residential neighborhood of Lasalle, a client recently entrusted us with a project to install a SHARP ZU1 18000 BTU wall-mounted heat pump to enhance thermal comfort in their living room. Located in a bright space with a decorative stone wall, this project came with specific technical constraints: optimal placement above a window, visual integration into the existing decor, and reliable heating performance during the harsh winters typical of Southwest Montréal.
At AirGreen, we handled this project with our expert approach to residential HVAC installation in Lasalle and throughout Montréal Island. The result: a high-performance, seamlessly integrated, functional, and silent heat pump, ready to tackle the extreme temperatures of Québec.
Why the SHARP ZU1 18000 BTU Model Was Chosen for This Project
The selection of this SHARP ZU1 wall-mounted heat pump came naturally. Equipped with a high-performance inverter compressor, eco-friendly R-32 refrigerant, and most notably, SHARP’s exclusive Plasmacluster technology, this unit combines energy efficiency, air purification, and extreme performance down to -27°C.
Key Technical Features:
-
Cooling capacity: 18,000 BTU/h (range: 6,000 to 21,600 BTU/h)
-
Heating capacity: 21,600 BTU/h (range: 5,500 to 25,600 BTU/h)
-
Performance at -27°C: up to 11,500 BTU/h – rare in this category
-
SEER 2: 24 / EER: 13
-
HSPF 2 (V): 9.0 – ideal for winter energy savings
-
R-32 refrigerant: more environmentally friendly than R-410A
-
Plasmacluster technology: active purification against bacteria, mold, and odors
-
Triple filtration system: HEPA filter, activated carbon, and washable pre-filter
-
Indoor noise level: only 28 dB in silent mode
A Transformed Lasalle Living Room: Complete Installation Description
The indoor unit was carefully installed above a window, in a tight space, with remarkable attention to aesthetics. The natural stone wall required precise anchoring without damaging the decorative finish. Our team:
-
Reinforced the mounting structure on the wall brackets.
-
Drilled the wall at an optimized angle to prevent water buildup.
-
Routed the refrigerant piping discreetly behind the unit to the exterior.
The outdoor compressor was installed on an elevated base at the back of the building, with anti-vibration protection, ensuring maximum durability.
User Comfort and Customer Benefits
The client expressed the need for a reliable secondary heating source, as well as comfortable cooling in summer, without experiencing the discomfort of direct airflow. The SHARP ZU1 fully meets this requirement thanks to:
-
Its wide airflow deflector with Coanda effect, gently directing air along the ceiling.
-
Automatic multi-directional airflow (vertical and horizontal).
-
Built-in Wi-Fi control for remote management via smartphone.
Additionally, indoor air is now continuously filtered thanks to the Plasmacluster system, contributing to better air quality for the whole family.
Financial Incentives and Grant Eligibility
This SHARP ZU1 18000 BTU wall-mounted heat pump qualifies for the Hydro-Québec LogisVert grant, as part of Québec’s residential energy transition program. Depending on configuration and household income, financial assistance of up to $1,704 may be available.
At AirGreen, we assist our clients through every step of the grant process, including:
-

Practical Tips to Keep in Mind If You're Planning a Similar Installation:
-
Strategic Placement: Always install the wall unit away from visual obstructions and in a central area for better airflow distribution.
-
Choose a Unit Rated for Low Temperatures: In Montréal, Laval, and the South Shore, harsh winters demand a heat pump certified for -27°C operation.
-
Account for Wall Materials: Stone, concrete, or drywall require different anchoring methods.
-
Check for Available Grants before selecting your system.
