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 Year-Round Comfort: A Seamless Heat Pump Installation in Montreal
At AirGreen, we understand that finding the perfect HVAC system for your home can make a world of difference, especially in a city like Montreal where temperatures fluctuate dramatically throughout the year. We recently completed the installation of a Sharp ZU1 24,000 BTU Mini Split Heat Pump for a customer in Montreal, and we’re excited to share how this energy-efficient system has transformed their home comfort.
Our client was looking for a solution that could handle Montreal’s icy winters and scorching summers with equal efficiency, and the Sharp ZU1 Mini Split fit the bill perfectly. Offering an impressive cooling capacity of 24,000 BTU and the ability to heat in temperatures as low as -27°C, this unit is a powerhouse of reliability and performance.
Why the Sharp ZU1? The Best Choice for Montreal’s Harsh Climate
The Sharp ZU1 isn’t just another heat pump; it’s a system designed to meet the needs of modern homeowners looking for advanced features, superior efficiency, and sustainability. Our customer was also thrilled to learn that this Sharp ZU1 model is eligible for the Hydro-Québec LogisVert Grant, allowing them to claim up to $2,688—the highest grant available for a 24,000 BTU unit!
But this installation wasn’t just about adding a new HVAC unit. It was about improving comfort, increasing energy efficiency, and ensuring long-term savings on energy bills.
Step-by-Step: The Installation Journey
For this installation, we focused on ensuring that every detail was executed to perfection. Here’s a quick breakdown of how we completed the process:
1. Initial Consultation
During our consultation, we discussed the customer’s requirements and evaluated their home’s heating and cooling needs. The 24,000 BTU Sharp ZU1 was chosen specifically for its ability to handle both larger rooms and extreme weather conditions.
2. Preparation and Planning
Since the Sharp ZU1 is known for its quiet operation and low energy consumption, we strategically placed the outdoor unit to minimize noise while maximizing efficiency. The compact dimensions of the outdoor unit (33.47 x 13 x 27.94 inches) allowed us to install it on the rooftop without compromising the space or aesthetics of the area.
3. Precision Installation
The installation included mounting the indoor unit, measuring 41.42 x 9.80 x 12.44 inches, in a central living area. The system was positioned for optimal air distribution and easy control through the built-in WiFi connectivity feature, which allows the client to adjust settings from their smartphone.
4. Energy Efficiency and Sustainability
The Sharp ZU1 uses the latest R-32 refrigerant, which reduces greenhouse gas emissions and cuts energy consumption by 10% compared to older systems. This aligns perfectly with our customer’s desire to lower their carbon footprint while benefiting from reliable heating and cooling all year round.
Advanced Features of the Sharp ZU1 24,000 BTU Heat Pump
Plasmacluster Technology: A Breath of Fresh Air
One of the standout features of the Sharp ZU1 is its Plasmacluster air purification system. Unlike most heat pumps, this technology not only regulates temperature but also purifies the air by eliminating mold, allergens, viruses, and bacteria. The client loved knowing that their air quality would improve while they stayed comfortable.
Coanda Airflow Control: Comfort Without the Drafts
The Coanda Airflow control system ensures that airflow is evenly distributed across the room. By directing air towards walls and ceilings, this feature prevents cold or hot drafts from blowing directly on people, which creates a more balanced and comfortable environment in every corner of the home.
Quiet Operation
At 53 dB(A) for the outdoor unit and as low as 25 dB(A) for the indoor unit, the Sharp ZU1 operates nearly silently, which was a major selling point for our client. They can now enjoy a peaceful environment without the usual hum of a typical HVAC system.
Ensuring Long-Term Performance
At AirGreen, we believe that a high-quality installation should last for years to come, which is why we offered our customer the 10-year extended warranty that covers the compressor, parts, and labor. The customer can rest easy knowing that their new Sharp ZU1 Heat Pump is backed by one of the best warranties in the industry.
A Greener Future with AirGreen and Sharp
By choosing the Sharp ZU1, our customer made an environmentally friendly decision. The unit’s use of the R-32 refrigerant and its Energy Star® certification reflect our commitment to helping customers lower their energy use and reduce their environmental impact.

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.
