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.
An Efficient and Elegant Solution for Year-Round Comfort
When it comes to creating a perfectly comfortable living space, AirGreen takes pride in delivering cutting-edge solutions tailored to the unique needs of every home. Recently, we installed a 12,000 BTU SHARP ZHU1 Mini Split Heat Pump in the heart of Dollard-des-Ormeaux, offering our customer an energy-efficient and environmentally friendly heating and cooling system. Let’s delve into the details of this project, from the high-performance features of the SHARP ZHU1 to the seamless installation process that left our customer thrilled.
Why Choose the SHARP ZHU1 Heat Pump?
The SHARP ZHU1 isn’t just any heat pump—it’s a system designed to endure and excel in Québec’s harsh climate. Whether it’s freezing at -27°C or sweltering in summer, this model guarantees year-round comfort. With an impressive 25.0 SEER rating and advanced features like the Plasmacluster ion technology, it offers unmatched efficiency and indoor air quality.
Key highlights of the SHARP ZHU1 include:
- Heating Capacity: Maintains a toasty 11,200 BTU/h even at -27°C.
- Cooling Capacity: A robust 12,000 BTU for peak summer days.
- Quiet Operation: With sound pressure as low as 22 dB(A) indoors, it ensures peace and tranquility.
- Energy Star Certified: Ensures optimal energy savings.
- WiFi Connectivity: Control your indoor climate anytime, anywhere.
- R32 Refrigerant: A greener choice that reduces environmental impact by lowering greenhouse gas emissions.
The Installation Process: Tailored to Perfection
Our team approached this project with precision, starting with a detailed consultation to understand the customer’s needs. The home in Dollard-des-Ormeaux presented a perfect setup for a ductless system, ideal for maintaining comfort without the need for extensive renovations.
Step 1: Strategic Placement for Maximum Efficiency
We began by selecting the ideal location for the outdoor condenser unit, ensuring it was mounted securely on a weather-resistant aluminum stand. This not only protects the unit from potential damage caused by debris and snow but also enhances its longevity. The placement also allowed for optimal airflow, critical for the heat pump's performance in extreme conditions.
Step 2: Indoor Unit Placement
The indoor unit was installed in a central location to evenly distribute air throughout the main living spaces. Its sleek and compact design blended seamlessly with the interior, proving that functionality and aesthetics can go hand in hand.
Step 3: High-Quality Piping and Insulation
Using premium materials, we carefully routed the refrigerant lines, ensuring efficient operation and minimal energy loss. Proper insulation was applied to maintain the integrity of the system and protect it from external temperature fluctuations.
Benefits of the SHARP ZHU1: Beyond Comfort
Our customer chose the SHARP ZHU1 not only for its performance but also for the incredible incentives available. This model qualifies for the $2,268 LogisVert grant by Hydro-Québec—the highest grant available for a 12,000 BTU heat pump in Québec. It’s not just a smart investment in comfort but also a step toward reducing energy bills and carbon footprints.
Unmatched Air Quality with Plasmacluster Technology
The SHARP ZHU1 is equipped with Plasmacluster ion technology, a proprietary feature that purifies indoor air by eliminating bacteria, viruses, and mold. This ensures a healthier environment, particularly for households with allergy sufferers or young children.
Durability and Reliability
Québec winters are no match for this unit. Thanks to its anti-corrosion coating and patented hot gas pipe system, the SHARP ZHU1 remains fully operational in temperatures as low as -27°C. The quick defrosting feature further ensures minimal downtime and uninterrupted heating.

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.
