At AirGreen, we are regularly called upon to carry out HVAC installation projects in unique architectural configurations. One of our recent projects, located in Boucherville, perfectly illustrates our ability to tackle technical challenges with precision and care. In this family home, we installed a SHARP ZU1 18,000 BTU wall-mounted heat pump, a unit known for its energy efficiency, optimized comfort, and compatibility with Québec’s harsh climate.
A Project Located in Boucherville, at the Heart of the South Shore
The residential sector of Boucherville, with its modern multi-level homes, often presents specific challenges for wall-mounted heat pump installations. This was certainly the case here, where the indoor unit had to be mounted on an angled wall in a stairwell with limited height and width.
A Demanding Indoor Configuration: Angled Wall and Restricted Access
One of the most notable aspects of this project was the indoor layout. The installation wall wasn’t vertical but slightly angled, which required a precise adjustment of the mounting bracket and a meticulous wall opening to pass the refrigerant and electrical lines without damaging the wall or compromising the room’s aesthetic.
Thanks to our professional lifting platform, we were able to keep the unit perfectly stable throughout the installation process, ensuring perfect and secure alignment.
Spotlight on the SHARP ZU1 18,000 BTU: Japanese Technology Built for Northern Performance
The SHARP ZU1 18,000 BTU heat pump, using R-32 refrigerant, is engineered to meet the demanding climate conditions of Québec. Here are a few technical highlights that set it apart:
-
Heating power up to 21,600 BTU/h, even in extreme winter conditions.
-
Heating capacity down to -27 °C, maintaining 11,500 BTU/h at that temperature.
-
SEER 2 rating of 24 and HSPF 2 of 9, proving excellent energy efficiency.
-
Plasmacluster feature, SHARP’s exclusive technology that purifies the air by neutralizing bacteria, viruses, and mold.
-
Automatic directional airflow with Coanda effect, ensuring even temperature distribution without direct drafts.
-
Built-in Wi-Fi, allowing smart remote control from a mobile phone.
-
Up to 10-year warranty (parts, compressor, and labor) when installed by a certified contractor such as AirGreen.
Key Steps of the Installation in This Boucherville Home
Initial Evaluation and Model Selection
After a thermal evaluation of the home, our team recommended the SHARP ZU1 18,000 BTU model, perfectly sized to ensure optimal comfort in high-air-volume zones like the stairwell and adjacent open areas.
Preparing the Installation Zone
We proceeded with the mounting bracket installation, carefully accounting for the sloped ceiling. The wall opening was done precisely to allow for refrigerant pipes, electrical wiring, and drainage, while preserving the interior finish.
Mounting the Indoor Unit
Using an adjustable lifting support, we mounted the unit at an angle calculated to avoid vibrations and ensure proper condensate drainage, even on an angled wall.
Refrigerant Line Hookup and Leak Testing
Copper piping was insulated with high-density sleeves and routed to the exterior. We conducted a nitrogen pressure test to ensure there were no leaks, followed by a meticulous vacuum pull before commissioning.
Startup and Calibration
The unit was powered on and calibrated according to the client’s preferences. We also connected the system to the home's Wi-Fi and guided the client through the SHARP app interface.
Maintenance Tips to Extend the Life of Your Unit
To ensure optimal HVAC maintenance, we recommend:
-
Quarterly cleaning of internal filters (microscreen + activated carbon).
-
Annual inspection by a certified AirGreen technician.
-
Keeping the area around the outdoor unit clear to avoid snow and ice buildup.
Testimonial from the Client
