Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
Experience the Ultimate Comfort with Our State-of-the-Art SHARP Heat Pump Installation in Oka
When it comes to delivering unparalleled comfort and efficiency, AirGreen always aims to exceed expectations. Recently, we completed the installation of a SHARP ZHU1 wall-mounted heat pump at a charming residence in Oka, showcasing the perfect blend of cutting-edge technology and practical design.
The Journey to an Energy-Efficient Home
The homeowners in Oka were seeking a reliable solution to manage the intense temperature fluctuations of Quebec's climate. Their goal? A system capable of keeping their home cozy during the harsh winters and refreshingly cool during the scorching summers. After a detailed consultation, we recommended the SHARP ZHU1—a machine recognized for its advanced features, impressive efficiency, and exceptional durability.
Why the SHARP ZHU1 Stands Out
- Cooling Capacity: 12,000 BTU, ideal for medium-sized spaces.
- Heating Capability: Performs efficiently even in temperatures as low as -27°C, perfect for Quebec's winter conditions.
- Ultra-Quiet Operation: Sound levels of just 22 dB(A) indoors ensure a serene home environment.
- Energy Efficiency: An outstanding SEER rating of 25.0.
- Advanced Technology: Includes Wi-Fi connectivity, allowing full control through a smartphone app.
The ZHU1 is also eligible for the LogisVert grant by Hydro-Québec, offering the homeowner an impressive $2,268 rebate—the largest available for any 12,000 BTU heat pump in Quebec.
A Thoughtful Installation Process
Our team arrived at the Oka property ready to transform the heating and cooling experience for our client. The home’s layout called for precise placement to ensure optimal performance and airflow. We mounted the sleek indoor unit with care, ensuring it blended seamlessly with the home’s decor. The outdoor unit was secured on a sturdy rooftop stand, designed to withstand Quebec’s demanding weather conditions.
Key Features of the Installation:
- Custom Mounting: Elevated placement of the outdoor unit to prevent snow accumulation.
- Insulated Piping: Ensured energy efficiency and long-term reliability.
- Aesthetic Integration: Discreet routing of piping and wiring to preserve the home's visual appeal.
The Benefits of R-32 Refrigerant
As part of our commitment to sustainability, the ZHU1 uses R-32 refrigerant, which offers:
- 10% Lower Energy Consumption: Compared to older refrigerants.
- Eco-Friendly: Reduces greenhouse gas emissions with a lower global warming potential.
- Improved Performance: Ensures the system operates efficiently year-round.
Technology that Redefines Comfort
The SHARP ZHU1 isn’t just a heat pump; it’s a comprehensive air quality solution. Equipped with Plasmacluster Technology, this system actively purifies the air, eliminating mold, viruses, and allergens. The result? A healthier, fresher home environment.
Plasmacluster Benefits:
- Neutralizes airborne bacteria and viruses.
- Removes mold and allergens.
- Deodorizes stubborn smells, including tobacco and cooking odors.
Coanda Airflow for Optimal Temperature Distribution
The Coanda airflow technology ensures that every corner of the home enjoys consistent temperatures. Whether directing warm air downward during winter or cool air upward in summer, the ZHU1’s design prioritizes comfort and energy efficiency.
Superior Connectivity and Control
With its built-in Wi-Fi, the SHARP ZHU1 offers unmatched convenience:
- Monitor and control the system remotely via a smartphone app.
- Access energy consumption reports to optimize efficiency.
- Use motion-sensor technology to adjust settings automatically when someone enters or leaves a room.
A Happy Customer in Oka
After completing the installation, the homeowners expressed their excitement about the new system. They were particularly impressed by the quiet operation of the indoor unit and the seamless integration of the outdoor compressor into their rooftop space. With the LogisVert rebate, they also appreciated the significant savings on their investment.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
