Careful installation of a Sharp ZU1 heat pump for lasting comfort in Laval
At AirGreen , we recently installed a Sharp ZU1 wall-mounted heat pump in a residential duplex in Laval-des-Rapides , a quiet and green neighborhood in Laval . This project perfectly illustrates our approach: technical precision, aesthetic integration and sustainable energy performance .
Installation context
The client wanted to replace an old wall-mounted air conditioner with a complete four-season heating and cooling solution . Our recommendation: the Sharp ZU1 , an energy-efficient heat pump with Eco Inverter and Plasmacluster Ion technology, ideal for the Quebec climate. This model stands out for its stable operation down to −25 °C and its high-efficiency compressor, perfect for ensuring consistent comfort throughout the year.
Optimized wall integration
The outdoor unit was fixed on sturdy wall brackets above the paved ground, ensuring good air circulation and protection against snow and moisture .
The installation required precise wall drilling for the exit of the refrigeration and electrical conduits, carefully sheathed in a discreet beige-colored capping , in harmony with the facade of the building.
Condensate drainage was carried out by natural gravity , eliminating the need for an additional pump — a plus for durability and ease of maintenance.

The advantages of the Sharp ZU1 model
The Sharp ZU1 is one of the new generation of R-32 wall-mounted heat pumps we offer at AirGreen. It combines exceptional energy efficiency , reduced noise levels and Plasmacluster air purification technology , which neutralizes viruses, allergens and bacteria in indoor air.
Thanks to its inverter compressor , the Sharp ZU1 automatically adapts its power according to the ambient temperature, considerably reducing electricity consumption.
This model is also eligible for grant programs such as Rénoclimat and Chauffez vert , thanks to its Energy Star® certification and its performance in extreme cold.
Adaptation to the Laval residential context
The Laval-des-Rapides duplex had a typical layout: vinyl walls, paved driveway, basement windows close to the installation area .
Our technicians therefore chose an installation height calculated to guarantee the stability of the support , while avoiding acoustic resonance against the facade.
The refrigeration path has been optimized to less than three meters, minimizing heat loss and maximizing system efficiency.
Final result: comfort, silence and aesthetics
At the end of the project, the client now benefits from a complete HVAC system , capable of ensuring optimal comfort in both summer and winter.
The exterior unit, sober and discreet, blends harmoniously into the residential environment.
Commissioning tests confirmed remarkable thermal stability , with energy efficiency greater than 18 SEER and a significant reduction in energy bills .
