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.
Delivering Innovative Comfort with Precision: The Sharp ZU Series
In the quaint neighborhood of Dollard-des-Ormeaux, Montreal, the HVAC specialists at AirGreen have once again demonstrated their commitment to providing superior climate control solutions with the installation of a Sharp ZU wall-mounted heat pump. This project not only showcases our expertise in handling complex installations but also emphasizes our dedication to enhancing comfort without compromising on space or aesthetics.
The Project Overview
For this particular installation, our client had a specific request: to install the compressor on the wall outside to avoid using valuable balcony space. This requirement presented a unique challenge, but our team was more than capable of meeting it. The selected location on the exterior red brick wall not only optimizes the unit's efficiency but also maintains the aesthetic integrity of the property. The Sharp ZU model, with its robust 18,000 BTU capacity, was an ideal choice for this setting, offering both cooling and heating capabilities suitable for Montreal’s diverse climate.
Technical Highlights and Features
State-of-the-Art Sharp ZU Series Attributes:
- Model Details: Sharp ZU1, with an interior dimension of 41.42 x 9.80 x 12.44 inches and an exterior dimension of 33.47 x 13 x 27.94 inches.
- Performance: Equipped to handle extremes with a cooling capacity of 18,000 BTU and heating down to -27°C.
- Energy Efficiency: Features a 24.0 SEER rating, ensuring optimal energy usage and compliance with upcoming 2025 energy regulations.
- Technology Integration: Includes WiFi connectivity and employs the revolutionary R-32 freon, marking a significant step towards environmental sustainability.
- Plasmacluster Technology: Unique to Sharp, this feature offers unmatched air purification, eliminating airborne viruses, allergens, and odors, thereby enhancing indoor air quality.
Installation Challenges and Solutions
Installing the compressor on an external wall posed specific challenges, particularly in ensuring stability and long-term reliability in a region known for its harsh weather conditions. Our team engineered a custom mounting solution that not only secured the unit impeccably against the brick facade but also allowed for easy maintenance and airflow optimization.
The strategic placement also took into account the noise levels, ensuring that the operational sound of the exterior unit, measured at 52 dB(A), did not intrude into the serene environment of our client’s home. This careful planning is crucial in densely populated areas where noise pollution can be a significant concern.
Client Satisfaction and System Benefits
The client was thoroughly impressed with the professional execution and the enhanced capabilities of their new heat pump system. The inclusion of a WiFi-enabled control system and Plasmacluster air purification technology particularly stood out, offering them a blend of convenience and health benefits not readily available with other systems.
This installation not only ensured a clutter-free balcony but also enhanced the property’s appeal and functionality, demonstrating AirGreen’s ability to tailor solutions to client needs without compromising on quality or performance.

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.
