An exemplary winter installation by AirGreen: performance, reliability and expertise
On this typical brick house in Saint-Léonard , our teams recently installed a Sharp ZU1 wall-mounted heat pump , a model known for its R-32 Inverter technology and exceptional performance even below -25°C . This project perfectly illustrates our expertise in residential HVAC installation in Greater Montreal.
A strategic replacement to maximize energy efficiency
The client had an old air conditioning unit, which was now obsolete and inefficient for winter heating. We therefore proposed the Sharp ZU1 , a highly efficient, Energy Star certified model, offering optimal comfort all year round. This replacement was part of an effort to reduce energy costs and access provincial subsidies available for high-efficiency heat pumps.
The technical features of this installation
This installation presented several challenges:
-
Brick wall requiring suitable anchors for wall brackets.
-
Installation height calculated to avoid any contact with snow and ensure optimal drainage.
-
Piping and wiring carefully capped and secured for discreet aesthetics and increased durability.
-
Gravity drainage to the outside, preventing pipes from freezing in winter.
The heat pump was mounted on galvanized wall brackets , providing excellent stability and protection against moisture and vibration. The insulated and covered refrigerant passage connects the outdoor unit to the indoor head with minimal drilling, ensuring wall integrity and system efficiency.
Optimal performance even in extreme conditions
The Sharp ZU1 is distinguished by its variable speed compressor , allowing for smooth and quiet operation. This model offers stable performance down to -25 °C , ensuring reliable heating even during the typical Saint-Léonard cold. The unit operates on R-32 refrigerant , which is environmentally friendly and more efficient than R-410A.
Thanks to this technology, the customer now benefits from:
-
Constant and economical heating ;
-
From rapid cooling during summer;
-
A significant reduction in energy costs ;
-
Quiet in operation , ideal for residential areas.
Winter, a factor we always anticipate
The installation took place in the middle of winter, in heavy snow conditions. We adjusted the height and orientation of the outdoor unit to ensure good air circulation and prevent ice buildup. This kind of detail makes the difference between a simple installation and a lasting engineering project .
