A discreet and efficient installation in a warm, welcoming Montréal neighbourhood
In the charming Villeray district, known for its tree-lined streets, classic duplex homes, and strong environmental awareness, AirGreen recently carried out the installation of a SHARP ZU1 12,000 BTU wall-mounted heat pump. This project, completed in a typical single-family residence in the area, aimed to deliver optimal year-round comfort, while integrating a solution that is discreet, energy-efficient, and at the cutting edge of technology.
Why choose the SHARP ZU1 wall-mounted heat pump?
The SHARP ZU1 is much more than just a basic cooling or heating unit. This specific model – the AY-XPC12ZU / AE-X12ZU – is engineered for northern climates, capable of maintaining high energy performance even in extreme temperatures down to -27°C. A particularly relevant feature in Montréal, where harsh winters demand superior HVAC capabilities.
Key technical specifications include:
-
Cooling capacity: 12,000 BTU/h
-
Maximum heating output at -27°C: 7,200 BTU/h
-
R-32 refrigerant: more eco-friendly, with roughly 66% lower GWP than R-410A
-
SEER of 21 / 22 and HSPF up to 12.5, for top-tier energy efficiency
-
Ultra-quiet operation (indoor noise level as low as 23 dB)
-
Plasmacluster technology: purifies the air by eliminating viruses, allergens, bacteria, and mold
-
Compact design: ideal for discreet wall-mounted integration
Installation context: constraints and tailored approach
The installation in this Villeray home came with several specific challenges, including:
-
Decorative crown molding on the ceiling in the main living area, requiring careful integration of the conduit for the drain line and wiring.
-
Interior load-bearing wall: we strategically positioned the unit to maximize the Coanda airflow effect, which ensures gentle and effective air distribution throughout the room.
-
Limited outdoor access: the compressor was installed in a small backyard space, with special attention to winter drainage and frost prevention.
Thanks to our experienced team and specialized equipment, the full installation was completed in a single day, including a full performance test, system balancing, and Wi-Fi configuration so the customer could control their heat pump remotely through the SHARP mobile app.
Real advantages for the customer
Just days after the installation, the customer already noticed a remarkable difference:
-
Fast cooling during the late summer heat
-
Stable and quiet heating in the evenings and at night
-
Noticeable reduction in indoor humidity, thanks to the integrated dehumidification function
-
Improved air quality: Plasmacluster technology works even in fan-only mode
The customer also expressed total satisfaction with the unit’s aesthetics: the sleek white wall-mounted unit blends perfectly with the interior decor, and the wiring is nearly invisible thanks to our attention to detail.
SHARP ZU1: a model perfectly suited to Montréal
The ZU1 12,000 BTU model is an ideal choice for medium-sized homes, especially in neighbourhoods like Villeray, Rosemont, Outremont, or Ahuntsic. It’s a great fit for:
-
Condo owners or homeowners looking for a compact and silent solution
-
Families concerned about air quality, especially with children or pets
-
Environmentally conscious clients looking for low-impact solutions, thanks to R-32 refrigerant and high energy efficiency
A solution eligible for government rebates
The SHARP ZU1 qualifies for several rebate programs, including:
-
Hydro-Québec’s LogisVert Program, which can provide up to $1,704 for this type of energy-efficient wall-mounted system
-
Rénoclimat Program, which rewards HVAC upgrades based on heat pump efficiency
At AirGreen, we always assist our clients with the paperwork and application process for rebates to help them maximize their return on investment.
