A customized installation for optimal performance in a demanding residential environment in Montréal
At AirGreen, we recently completed the installation of a SHARP BU DoubleZone wall-mounted heat pump in a residential home located in Montréal-Nord, an area known for its harsh winters and increasingly hot summers. The goal of this project was to provide our client with year-round thermal comfort, superior air quality, and remarkable energy efficiency. Thanks to our expertise and the advanced Japanese technology of SHARP, we successfully delivered on that promise.
Installation context: Comfort, discretion, and efficiency
Our client was looking for a dual-zone solution to cover two main areas: a spacious living room and an adjacent bedroom, both located on the upper floor of the home. The objective was to have independent temperature control, enhanced energy efficiency, and a quiet system, all without compromising the interior design.
After a thorough on-site evaluation and an in-depth conversation with the client, we recommended installing the SHARP BU DoubleZone wall-mounted heat pump, a system known for its exceptional performance in cold climates and reliable operation down to -27°C.
Why choose the SHARP BU DoubleZone Series?
The SHARP BU DoubleZone, paired with two AY-XPC12BU indoor units, delivers up to 26,000 BTU/h in heating power and 24,000 BTU/h in cooling, easily covering the thermal needs of both rooms. Here are some of the technical specifications that influenced our recommendation:
-
R-32 refrigerant: more eco-friendly, with a global warming potential (GWP) 70% lower than R-410A.
-
Plasmacluster technology: actively purifies the air by neutralizing viruses, bacteria, mold, and odors.
-
SEER rating up to 25 / HSPF 11.5: ensuring top-tier energy efficiency.
-
Reliable operation down to -27°C thanks to SHARP’s patented HOT GAS PIPE system, which prevents ice buildup in the outdoor unit.
-
Built-in smart controls with Wi-Fi, compatible with Alexa and Google Assistant.
Project stages for the Montréal-Nord installation
Needs assessment and strategic planning
We began with a thermal analysis of the two zones to be conditioned. The living room, facing south with large windows, required precise sizing to avoid energy loss. The bedroom, more insulated, needed consistent and quiet night-time comfort.
Preparation and aesthetic integration
Our team proposed a high wall-mounted integration, both discreet and effective. The sleek finish of the SHARP indoor unit blended seamlessly with the modern decor of the home. Refrigerant and electrical lines were routed strategically to avoid impacting visible walls, especially around the staircase area.
Technical installation and functional testing
We installed the AE-X3M24BU outdoor unit on a wall bracket at the back of the house, with enhanced insulation and a raised base to handle Montréal’s snowfall. The refrigerant circuit was pressure-tested with nitrogen to detect microleaks, then vacuumed and charged according to SHARP’s specifications.
Finally, we performed full system testing, confirming stable temperature control, quiet airflow, and continuous air purification through Plasmacluster ions.
Real-world results for our client
The installation was completed in a single day. The client immediately noticed the thermal comfort difference: a cool and pleasant living room even during peak summer, a warm and steady bedroom in winter, and air that’s constantly purified.
Additionally, the SHARP mobile app allows the client to manage both zones independently and remotely. This feature is particularly helpful for adjusting the temperature before returning home or saving energy while away.
Financial aid and available grants
This type of installation qualifies for several financial assistance programs, including:
-
Hydro-Québec’s LogisVert Program
-
RénoClimat tax credit
-
Federal Green Homes Grant (up to $5,000 in subsidies)
Our team helps each client prepare their grant application, ensuring they get the best possible return on their investment.
