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 Next-Level Comfort with a SHARP ZU1 Installation in Saint-Lambert
A Modern HVAC Solution Tailored for Extreme Weather Conditions
At AirGreen, we pride ourselves on providing cutting-edge solutions to meet the unique heating and cooling needs of our customers. Our recent installation of the SHARP ZU1 15,000 BTU Wall-Mounted Heat Pump in Saint-Lambert is a testament to our commitment to delivering unparalleled comfort, energy efficiency, and reliability.
Why the SHARP ZU1 Stands Out
The SHARP ZU1 series is not just another mini split heat pump. It combines advanced technology, sleek design, and unmatched performance to create a perfect balance of functionality and aesthetics. Here’s what makes this model special:
- Extreme Weather Performance: With a heating capacity of up to -27°C, this heat pump is ideal for Quebec’s harsh winters.
- Energy Efficiency: Boasting an impressive 24.0 SEER rating, it ensures lower energy bills without compromising performance.
- Environmentally Friendly Refrigerant: Utilizing R-32 freon, the SHARP ZU1 reduces greenhouse gas emissions and complies with upcoming energy regulations.
- Quiet Operation: At just 23 dB(A) indoors, it’s whisper-quiet, making it perfect for bedrooms or study areas.
The Saint-Lambert Installation Story
Every installation tells a unique story, and this one is no exception. The homeowner approached us seeking a reliable solution to maintain optimal indoor temperatures year-round. Their primary requirements were energy efficiency, compatibility with government grants, and the ability to withstand extreme cold.
A Seamless Process
Our expert technicians began with a comprehensive assessment of the home, identifying the perfect location for the indoor and outdoor units. The indoor unit, with its sleek dimensions of 41.42 x 9.80 x 12.44 inches, was installed above a doorframe to maximize airflow without disrupting the room’s aesthetics. The outdoor unit, compact yet robust, was strategically placed to ensure optimal performance while minimizing noise.
Government Grants Made Easy
The homeowner was thrilled to learn that the SHARP ZU1 qualifies for the $2,172 LogisVert grant—the highest grant available for a 15,000 BTU heat pump. We guided them through the application process, ensuring they could take full advantage of this incentive.

Data read live from the airgreen.ca page of each size (NEEP / AHRI certified performance). When the title names the installed size, it is highlighted; otherwise the whole range is shown. The aid shown is today’s, using Hydro-Québec’s rule ($120 per 1,000 BTU/h at −8 °C); amounts quoted in the article date from its publication. Only Hydro-Québec confirms the assistance granted.
And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Baseboards and electric furnaces turn 1 kWh of electricity into 1 kWh of heat. A heat pump delivers more: that is its COP. At Hydro-Québec’s rate D (11.142¢/kWh above 40 kWh a day, since 1 April 2026):
Hydro-Québec: a heat pump can be up to three times more efficient than baseboards for heating in the colder months.
Estimate per kWh of heat, at the chosen temperature, using the certified COP from the product page. Taxes, access charge and backup heat not included.
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.
