In a charming bungalow located in a quiet, tree-lined neighborhood of Laval, our team recently completed the installation of a SHARP ZU1 15000 BTU wall-mounted heat pump. At AirGreen, every project is an opportunity to transform a living space through heating, ventilation, and air conditioning (HVAC) technology that is reliable, quiet, and energy efficient. And this installation, while visually discreet, stands out for its year-round performance.
A smart choice for year-round comfort
Our clients—a retired couple—wanted to replace their outdated wall-mounted air conditioner that could no longer meet today’s standards. Their priorities: an energy-efficient solution, one that performs in cold winters and actively purifies indoor air. After an on-site technical evaluation, we recommended the SHARP ZU1 15000 BTU wall-mounted heat pump, a high-performing model well-suited for the Québec climate and particularly popular in Laval, Montréal, and the North Shore.
Why the SHARP ZU1 15000 BTU?
Here are the key features of this model that led to our recommendation:
-
Heating capacity up to 18,000 BTU/h and cooling up to 17,000 BTU/h, perfect for a medium-sized living room or open space.
-
Operates efficiently down to -27°C, thanks to SHARP’s patented “Hot Gas Pipe” technology that prevents freezing of the outdoor unit.
-
Uses R32 refrigerant, environmentally friendly, with a 68% lower global warming potential than R-410A.
-
Built-in Plasmacluster technology: actively purifies indoor air by neutralizing mold, viruses, bacteria, and odors.
-
SEER rating of 24, HSPF of 11.8, delivering superior energy efficiency.
-
Sleek, compact, and quiet design, with indoor noise levels as low as 26 dB.
-
Smart connectivity with integrated Wi-Fi, compatible with Google Assistant and Alexa.
A precise and aesthetic installation by AirGreen
The installation process was carefully planned. Here's an overview of the key steps of our intervention:
Initial inspection and planning
First, our technician assessed the space layout: walls, openings, insulation, and electrical panel location. Since the area to condition was a spacious, light-filled living room, it was essential to avoid direct airflow on occupants while maximizing warm or cool air distribution.
Wall mounting and drilling
The indoor unit was installed above a large art canvas, at an optimized height to allow for the Coanda effect, where air flows smoothly along surfaces. This strategic positioning ensures even heating and cooling, without direct drafts.
Drilling to the exterior was done at a precise angle to ensure natural drainage of condensation, avoiding backflow or mold growth.
Connecting the outdoor unit
The outdoor unit was installed on a wall-mounted anti-vibration bracket at the back of the house. This setup offers better protection from snow buildup while reducing noise. We used 1/4 x 3/8 inch insulated piping, compliant with SHARP specifications and within the maximum allowed length of 20 meters.
Commissioning and checks
Once all connections were sealed and insulated, we performed a leak test, followed by nitrogen pressure testing and vacuum pull-down. The heat pump was then activated and tested in cooling and heating modes, verifying pressure levels, temperature output, and airflow. Everything was confirmed to meet SHARP’s standards.
Air purification you can feel—and breathe
This SHARP ZU1 model goes far beyond temperature control. With built-in Plasmacluster technology, it continuously purifies the air. This technology emits positive and negative ions that:
-
Eliminate allergens like dust mites and pollen
-
Neutralize odors from cooking or tobacco
-
Suppress airborne mold and viruses
-
Improve indoor air quality, especially for people with asthma or sensitivities
Our clients have already told us they feel the air is lighter and fresher, just hours after installation.
Eligibility for grants and long-term energy savings
Great news for homeowners in Laval and on the South Shore: this installation qualifies for Hydro-Québec’s LogisVert program, offering up to $2,172 in rebates, depending on eligibility and home configuration. We always guide our clients through the application process to help maximize their return on investment.
Customer testimonial: satisfaction above all
"The AirGreen team was fast, courteous, and above all, very professional. Since the installation, our home feels more comfortable, and we’ve even noticed a drop in our electricity bills. Many thanks!"
