Bringing Energy Efficiency and Comfort to Historic Montreal Homes
We recently completed the installation of a Sharp ZU1 18,000 BTU wall-mounted heat pump in the picturesque neighborhood of Old Port, Montreal. Known for its charming cobblestone streets and historic architecture, Old Port is an area where modern amenities need to blend seamlessly with the classic character of the homes. For this project, our team at AirGreen was tasked with installing an energy-efficient heating and cooling solution without disturbing the aesthetic integrity of the home.
Why the Sharp ZU1?
The Sharp ZU1 is not your average wall-mounted heat pump. This system is equipped with R-32 refrigerant, making it an environmentally friendly choice for homeowners. It’s perfect for Montreal’s fluctuating weather, capable of heating even during outdoor temperatures as low as -27°C. The 18,000 BTU capacity ensures that it can efficiently cool and heat medium-sized spaces, providing year-round comfort.
Key Features of the Sharp ZU1:
- Cooling Capacity: 18,000 BTU
- Heating Capacity: Operational up to -27°C
- Energy Efficiency: 24.0 SEER rating
- Dimensions: Interior Unit (41.42 x 9.80 x 12.44), Exterior Unit (33.47 x 13 x 27.94)
- WiFi: Built-in, offering seamless control via smartphone
- Sound Levels: Whisper-quiet operation with an indoor sound pressure level of 25-49 dB(A)
- Refrigerant: Environmentally friendly R-32 gas, reducing greenhouse emissions and improving energy efficiency
Installation Challenges and Solutions
Every installation comes with its own set of unique challenges, and this project was no exception. The home’s layout and the narrow entryway near the front door required a strategic approach. We wanted to install the interior unit above the front door to maximize space while ensuring optimal airflow. Our team skillfully routed the necessary piping and electrical wiring without compromising the home’s historical aesthetic. By carefully planning the installation, we were able to ensure that the Sharp ZU1’s sleek, modern design fit perfectly into the traditional home.
This model's quiet operation was a key selling point for the homeowners. With sound pressure levels as low as 25 dB(A) indoors, they can enjoy comfortable temperatures without the hum of a typical HVAC system interrupting their quiet evenings at home.
Plasmacluster Technology: Healthier Air, Cleaner Home
One of the standout features of the Sharp ZU1 is its Plasmacluster technology, which works to purify the air by neutralizing harmful particles like airborne bacteria, viruses, and allergens. This technology offers superior air quality compared to traditional systems, making it a perfect choice for urban homes in bustling areas like Old Port, where outdoor pollutants can often make their way indoors.
Coanda Airflow Control: A Smart Approach to Even Temperature Distribution
The Sharp ZU1 also features Coanda airflow control, an innovation that helps direct air along the walls and ceilings for more uniform temperature distribution. In a space like this Old Port home, which has an open layout, this feature ensures that the temperature remains consistent across rooms without creating uncomfortable drafts. Whether it’s the height of summer or the depths of winter, the Sharp ZU1 guarantees comfort at all times.
Grants and Rebates for Energy-Efficient Solutions
The Sharp ZU1 is eligible for several government grants, including:
- Hydro-Québec’s LogisVert Grant: Up to $2,640 with an additional 25% bonus when paired with Hilo Thermostats.
- Federal Grant: Between $2,500 and $5,000 in federal rebates for energy-efficient installations.
These rebates significantly reduce the upfront cost of the installation, making it an affordable option for homeowners who want to make eco-friendly upgrades.

The Installation Process
-
Assessment: We performed a thorough inspection of the home to determine the optimal placement for the Sharp ZU1. Given the layout, we decided that mounting the unit above the front door would provide the best airflow while maintaining the room’s design integrity.
-
Piping and Wiring: Our experienced technicians routed the piping and electrical wiring through discrete channels to minimize their visibility. The connection to the exterior unit was made through the narrow space between the doorframe and the wall, a delicate process that required precision and care.
-
Mounting the Units: The interior unit, with its dimensions of 41.42 x 9.80 x 12.44, fit perfectly above the door, blending into the home’s existing décor. The exterior unit, installed in a side alley, was placed strategically to ensure optimal airflow and easy access for future maintenance.
-
Testing: After installation, we thoroughly tested the system to ensure that it was operating at peak efficiency. The Sharp ZU1 exceeded all expectations, providing both cooling and heating as intended, even as temperatures outside fluctuated.
Conclusion: Efficiency Meets Elegance
