Installation of a Sharp ZU1 Mini Split Heat Pump in La Prairie
Discover how two neighbors in La Prairie upgraded their comfort with Sharp ZU1 heat pumps, benefiting from a $2,172 grant and our exclusive group discount.
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.
A Perfect Pairing: Comfort and Efficiency for Two Neighbors in La Prairie
When it comes to upgrading home comfort systems, our recent installation in La Prairie stands as a testament to the precision and care that AirGreen brings to every HVAC project. In this instance, we had the privilege of installing not just one but two separate 15,000 BTU Sharp ZU1 mini split heat pumps, serving two neighboring households. This was no ordinary job; it was a collaborative effort where two neighbors decided to seize the opportunity for a group discount, making their investment in home comfort not only smart but also cost-effective.
Why the Sharp ZU1 Stands Out
The Sharp ZU1 wall-mounted heat pump is more than just a heating and cooling unit; it is an energy-efficient solution designed for the Quebec climate, capable of operating at temperatures as low as -27°C. Equipped with the latest R-32 refrigerant, this model provides a greener alternative while improving energy efficiency by nearly 10%. The reduction in greenhouse gas emissions makes it not just an economical choice but also an environmentally conscious one.
Moreover, the Sharp ZU1’s advanced Plasmacluster technology offers superior air purification, neutralizing airborne bacteria, viruses, and allergens, and even eliminating odors and mold. It’s a feature that ensures not just comfort but also healthier indoor air quality, a significant factor for homeowners who value a safe living environment.
Dual Installations: Enhancing Comfort for Two Families
This project was not just about installing the Sharp ZU1 mini split; it was about enhancing the living experience of two families who made a joint decision to upgrade their homes. The dual installation allowed us to offer a group discount, which added to the value and satisfaction of our customers. Both units were meticulously placed to ensure optimal airflow and temperature control, with the interior units positioned for even temperature distribution across the living spaces.
The installation was carried out with precision, ensuring that the condensate drainage, electrical connections, and refrigerant piping were all flawlessly executed. The outdoor units, placed side by side, were installed on a raised platform to protect against ground-level moisture and debris, a common concern in La Prairie's variable weather conditions. This not only improves the longevity of the units but also facilitates easier maintenance down the road.
Maximizing Savings: The $2,172 LogisVert Grant
Homeowners are always on the lookout for ways to maximize their investment, and these neighbors were no exception. The Sharp ZU1 heat pump qualifies for the highest LogisVert Grant available for 15,000 BTU models in Quebec, amounting to an impressive $2,172. This significant rebate played a crucial role in the decision-making process, making the upgrade to a Sharp ZU1 system an even more attractive option. The grant not only offsets the initial installation cost but also ensures long-term savings on energy bills due to the system's high efficiency rating of 24.0 SEER.
Why Choose the Sharp ZU1 for Your Home?
1. Plasmacluster Technology for Superior Air Quality
Sharp’s exclusive Plasmacluster air purification system sets the ZU1 heat pump apart from the competition. It works by diffusing ions that actively target and neutralize airborne contaminants, including viruses, bacteria, and allergens. Unlike conventional air purifiers, Plasmacluster technology offers a natural approach to air cleaning, enhancing the quality of indoor air for healthier living.
2. Coanda Airflow Control for Uniform Temperature
The Sharp ZU1 is also equipped with Coanda airflow control, a feature that uses the natural tendencies of air movement to distribute heated or cooled air more evenly throughout the home. This means no more cold spots in winter or stifling heat in summer. The airflow is directed strategically, reaching deep into corners and larger spaces, ensuring that the temperature remains consistent in every room.
3. Inverter Technology for Energy Efficiency
Unlike traditional HVAC systems that switch on and off, the Sharp ZU1's inverter technology allows it to modulate its operation to maintain the desired temperature without the need for frequent stops and starts. This energy-saving feature reduces wear and tear on the system, making it more durable and cost-effective in the long run.
4. Built for Extreme Climates
Quebec’s winter is no match for the Sharp ZU1, which continues to perform efficiently down to -27°C. Its hot gas pipe system prevents the outdoor compressor from freezing, ensuring that you stay warm and comfortable even during the coldest months. Additionally, the defrost function is optimized to minimize downtime and keep the indoor temperature steady.
The Installation Experience: What Made It Special
This particular project was memorable not just for the quality of the equipment installed but for the community spirit it represented. Neighboring families coming together to enhance their home comfort speaks volumes about the power of collaboration and the value that AirGreen adds by offering group discounts for such installations. The satisfaction of knowing that two families can enjoy state-of-the-art heating and cooling systems while also benefiting from financial incentives makes our job all the more fulfilling.
Attention to Detail
We took every measure to ensure that both installations were done to the highest standards. This included using anti-vibration pads for the outdoor units to minimize noise, as well as installing protective covers for the refrigerant piping to shield them from UV damage. Every connection was double-checked, and extensive tests were conducted to confirm that each unit was functioning at its peak efficiency before we considered the job complete.
A Commitment to Customer Satisfaction
Both households expressed their gratitude for the personalized service and attention to detail that AirGreen provided. Our technicians took the time to explain the system’s features and demonstrate the mobile app controls, ensuring that the homeowners felt confident in using their new Sharp ZU1 heat pumps.
Sharp ZU1: The Ideal Choice for La Prairie Homes
Whether you’re looking to reduce energy costs, enhance indoor air quality, or simply enjoy a more comfortable living environment, the Sharp ZU1 mini split heat pump delivers on all fronts. Its combination of cutting-edge technologies like Plasmacluster and Coanda airflow control, paired with extreme cold performance, makes it one of the best HVAC solutions for homes in Quebec.

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.
