An exemplary winter installation of energy efficiency by AirGreen
At AirGreen , we know that installing a wall-mounted heat pump isn't just about putting a unit on a wall: it's about energy performance, sustainable comfort, and long-term reliability. With this in mind, our team recently installed a Sharp ZU1 Eco Inverter in Sainte-Rose, Laval , in the heart of a typical residence in the area. Despite the presence of snow and sub-zero temperatures, the project was carried out with precision and without compromising on quality.
A typical residential context of Laval
The client, owner of a single-story single-family home , was looking for a high-performance solution to reduce heating costs while enjoying optimal comfort year-round. The old unit, aging and energy-intensive, was no longer able to ensure stable performance in extreme cold. Our recommendation: the Sharp ZU1 , a highly efficient wall-mounted heat pump designed for the Quebec climate.
The Sharp ZU1: a strategic choice for Quebec winters
The Sharp ZU1 Eco Inverter is one of the most popular models in our residential range. Equipped with Plasmacluster Ion technology, it improves indoor air quality while offering exceptional energy efficiency.
Main technical characteristics:
-
Capacity ranging from 12,000 to 24,000 BTU , depending on the needs of the residence.
-
Stable operation down to −25°C , ideal for North Shore winters.
-
Eco Inverter technology to automatically adjust compressor power according to actual temperature.
-
R-32 refrigerant, more ecological and efficient.
-
Minimal noise level, ensuring remarkable acoustic comfort.
The ZU1 series is also eligible for certain energy subsidies from the Quebec government, a significant advantage for homeowners keen to invest in a sustainable and economical solution.
The challenges of installing in winter conditions
Installing a heat pump in the middle of winter requires careful planning. In Sainte-Rose, our team had to deal with snow on the ground and sub-zero temperatures , as well as limited lateral access to the facade where the compressor was to be installed.
Solutions implemented:
-
Raised metal support : to avoid direct contact with snow and ensure optimal air circulation around the condenser.
-
Wiring and piping protected by rigid white capping , perfectly integrated into the beige vinyl facade of the house.
-
Gravity drainage provided to prevent ice formation under the unit.
-
Direct electrical connection via a nearby waterproof box, ensuring safety and compliance with standards.
Every detail has been designed to ensure the reliability and durability of the installation, even in the most demanding climatic conditions.
A clean and durable finish
We place particular importance on the aesthetics and cleanliness of our facilities. The Sharp ZU1 was installed at an ideal height to facilitate maintenance and allow for adequate airflow. The refrigeration line routing was carefully concealed, preserving the visual harmony of the façade.
The entire system was then tested under real-life conditions: refrigerant gas pressure measurement, condensate flow verification, compressor calibration and thermal efficiency validation. This confirmed excellent energy performance , even at -10°C at the time of commissioning.
The result: comfort, economy and peace of mind
Thanks to this installation, the customer now benefits from:
-
Constant and economical heating all winter long.
-
Rapid and even cooling during the summer.
-
Improved air quality thanks to Plasmacluster technology.
-
Simplified maintenance , the unit being easily accessible for cleaning the filters and annual checks.
The installation also helped reduce the overall energy consumption of the home , an aspect particularly appreciated by Laval residents seeking to limit their environmental footprint.
