A custom installation for optimal performance in a demanding Montreal residential environment
At AirGreen , we recently completed a SHARP BU DoubleZone wall-mounted heat pump installation in a residential home located in Montreal North , an area where winters are harsh and summers are increasingly hot. The goal of this mission was to offer our client 4-season thermal comfort, superior air quality and remarkable energy efficiency. Thanks to our expertise and SHARP 's advanced Japanese technology, we were able to successfully meet this challenge.
Installation context: Comfort, discretion and efficiency
Our client was looking for a dual zone solution to cover two main rooms: a spacious living room and an adjacent bedroom, both located on the upper floor of the house. The desire was to have independent temperature control , increased energy efficiency and a quiet system , without compromising the interior design.
After a complete site assessment and in-depth discussion with the client, we recommended the installation of a SHARP BU DoubleZone wall-mounted heat pump , a system renowned for its exceptional performance in northern climates and reliable operation down to -27°C.
Why the SHARP BU DoubleZone series?
The SHARP BU DoubleZone , combined with two AY-XPC12BU indoor units, offers a heating capacity of up to 26,000 BTU/h and a cooling capacity of 24,000 BTU/h , more than covering the thermal needs of both rooms. Here are some of the technical features that motivated our choice:
-
R-32 refrigerant : more environmentally friendly, with a 70% lower global warming potential (GWP) compared to R-410A.
-
Plasmacluster Technology : active air purification, neutralizing viruses, bacteria, mold and odors .
-
SEER rating up to 25 / HSPF 11.5 : guaranteeing high level energy efficiency.
-
Reliable operation down to -27°C thanks to the patented HOT GAS PIPE system, preventing ice formation in the outdoor unit.
-
Built-in Wi-Fi smart controls , compatible with Alexa and Google Assistant.
Stages of the installation project in Montreal North
Needs assessment and strategic choice
We began with a thermal analysis of the two areas to be air-conditioned. The south-facing living room with large windows required precise sizing to avoid efficiency losses. The bedroom, more insulated, required stable and quiet nighttime comfort.
Preparation and aesthetic integration
Our team proposed a high-wall integration that was both discreet and efficient. The sleek finish of the SHARP indoor unit blends perfectly with the modern aesthetic of the residence. The routing of the refrigeration and electrical wiring was optimized to avoid affecting the visible walls, particularly in the stairwell.
Technical installation and functional testing
We installed the AE-X3M24BU outdoor unit on a wall mount at the back of the house, with reinforced insulation and a raised base to withstand Montreal's snow. The refrigeration circuit was pressurized with nitrogen to detect any microleaks, then evacuated and charged according to SHARP's specifications.
Finally, comprehensive tests were carried out, confirming stable temperature, quiet airflow, and active air purification thanks to Plasmacluster ions .
Concrete results for our client
The installation was completed in just one day. The client immediately felt the difference in thermal comfort : a cool and pleasant living room even in the middle of summer, a warm and stable bedroom in winter, and continuously purified air .
Furthermore, the integration of the SHARP mobile application allows the customer to manage both zones independently and remotely. This feature is particularly useful for adjusting the temperature before returning home or for saving energy in away mode .
Financial aid and grants available
This type of installation is eligible for several financial assistance programs, including:
-
Hydro-Québec's LogisVert Program
-
RénoClimat tax credit
-
Federal Green House Grant (grants up to $5,000)
Our team supports each client in putting together their grant application , in order to optimize their return on investment.
