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.
Installation of a Sharp ZHU Wall-Mounted Mini Split in Pierrefonds, Montreal
At AirGreen, we pride ourselves on delivering top-notch HVAC services across Montreal, Laval, Longueuil, North Shore, and South Shore. Our latest installation project took us to the heart of Pierrefonds, Montreal, where we installed a state-of-the-art Sharp ZHU Wall-Mounted Heat Pump. This project was not just about installing an HVAC unit; it was about overcoming challenges, ensuring customer satisfaction, and enhancing the comfort of a home.
The Sharp ZHU Wall-Mounted Heat Pump
The Sharp ZHU is a wall-mounted heat pump that stands out for its exceptional energy efficiency and advanced features. This model is Energy Star® certified and comes with a cooling capacity of 18,000 BTU. It's equipped with WiFi for easy control and monitoring, and it operates with an impressive efficiency of 25.0 SEER. The Sharp ZHU is also designed for quiet operation, with a sound pressure level of just 52.0 dB(A) outside and 25 / 49 dB(A) inside.
This heat pump uses R-32 Freon, a modern refrigerant that reduces greenhouse gases and energy consumption by around 10%. The Sharp ZHU also boasts Plasmacluster technology for superior air purification, neutralizing bacteria, viruses, mold, and allergens.
The Installation Process
The installation of the Sharp ZHU in Pierrefonds was a challenging yet rewarding process. The location required us to navigate through a large layer of masonry and one room to install the unit in the center of the house, atop a stairway. This strategic placement allows for optimal heating and cooling across two floors.
Despite the complexity, our team was committed to ensuring a flawless installation. We took our time to ensure that every step was executed with precision, and the result was a perfectly installed heat pump that the customer was thrilled with.
The Benefits of the Sharp ZHU
The Sharp ZHU is not just an HVAC unit; it's a solution that enhances the comfort and quality of life in your home. It's designed to withstand extreme cold temperatures and includes a Multi Space Function and "Spot Air" mode for targeted cooling or heating.
The Sharp ZHU also comes with a generous warranty package (10-10-10), ensuring peace of mind for years to come. And with the Provincial Grant of $700 that this model is eligible for, it's an investment that truly pays off.

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.
