Installation of a SHARP ZHU1 12,000 BTU Mini Split Heat Pump in Sainte-Thérèse
Experience ultimate comfort with the SHARP ZHU1 Mini Split Heat Pump! Installed by AirGreen in Sainte-Thérèse, this energy-efficient system thrives even at -27°C.

In summer, the outdoor unit rejects the house's heat outside.

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.
Transforming Comfort with Cutting-Edge HVAC Solutions
At AirGreen, we take pride in creating efficient, sustainable, and tailor-made HVAC solutions for our clients. This latest project in Sainte-Thérèse is no exception. The installation of the SHARP ZHU1 12,000 BTU Mini Split Heat Pump demonstrates our commitment to delivering high-performance systems capable of thriving in Quebec’s diverse climate.

Why the SHARP ZHU1 Stands Out
Energy Efficiency Meets Innovation
This 12,000 BTU ductless heat pump is an Energy Star® certified system, boasting an impressive 25.0 SEER rating. Its cutting-edge R-32 refrigerant minimizes environmental impact while maximizing energy savings. With a 10-year warranty on parts, labor, and the compressor, it’s not just an investment in comfort but in long-term reliability.
The SHARP ZHU1 is also eligible for the Hydro-Québec LogisVert grant, offering a rebate of up to $2,268, the highest for a 12,000 BTU model in Quebec. This incentive further emphasizes the energy-saving and eco-friendly capabilities of this heat pump.
Technical Mastery: Designed for Quebec Winters
The SHARP ZHU1 is no ordinary heat pump. Its heating capacity of -27°C ensures seamless operation during even the harshest Quebec winters. This feature alone makes it a popular choice for homes in the Greater Montreal area, including Laval, Longueuil, and beyond.
Key Specifications:

- Heating Capacity: -27°C
- Sound Levels:
- Indoor: 22-44 dB(A)
- Outdoor: 49 dB(A)
- WiFi Connectivity: Included

The Installation Journey: Customizing Comfort in Sainte-Thérèse
For this project, our team carefully evaluated the client’s home layout to determine the most efficient placement for the SHARP ZHU1 Mini Split Heat Pump. Our goal was to maximize comfort while ensuring a seamless integration with the property’s aesthetic.
Installation Highlights:
-
Strategic Placement:
The outdoor unit was securely mounted on a reinforced bracket to optimize airflow and reduce vibration. Its compact dimensions (30.72 x 10.59 x 21.25 inches) made it an ideal fit for the space. -
Silent Indoor Comfort:
The indoor unit was installed in the main living area, chosen for its quiet operation at just 22 dB(A), ensuring a peaceful environment for the homeowners. Its sleek design blended perfectly with the modern interior. -
Precise Piping and Electrical Work:
Our team utilized high-quality materials for the refrigerant piping and electrical connections, ensuring durability and efficiency. With the freon type R-32, this system achieves a 10% reduction in energy consumption compared to older refrigerants. -
Advanced Testing:
Before finalizing the installation, we conducted rigorous performance tests to confirm optimal heating and cooling across the home. The WiFi-enabled control system was configured, allowing the client to monitor and adjust settings conveniently from their smartphone.
Features That Enhance Daily Life
Plasmacluster Air Purification
One of the standout features of the SHARP ZHU1 is its Plasmacluster technology, which actively neutralizes airborne bacteria, viruses, and allergens. This ensures that the air circulating in the home is not only at the perfect temperature but also healthier to breathe.
Quiet Yet Powerful
Despite its powerful performance, the system operates at whisper-quiet levels. Whether heating or cooling, the SHARP ZHU1 creates a comfortable environment without the intrusive noise typical of older models.
Smart Connectivity
The included WiFi feature allows for real-time adjustments via the SHARP app. Users can track energy usage, set schedules, and even enable GPS-linked controls to optimize performance when they’re away from home.

Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

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.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
