Installation of a SHARP ZU1 Wall-Mounted Heat Pump in Blainville
Discover how AirGreen transformed a Blainville home with the SHARP ZU1 heat pump, combining advanced air purification, energy efficiency, and superior comfort.
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 Modern Comfort Solution for Blainville Homes: Why This Installation Stands Out
At AirGreen, we pride ourselves on delivering outstanding CVAC solutions that not only offer modern technology but are also highly efficient and environmentally responsible. Our recent installation in Blainville showcases the SHARP ZU1 24,000 BTU wall-mounted heat pump—a true gem in energy-efficient heating and cooling.
This state-of-the-art system, equipped with Plasmacluster™ air purification and Coanda airflow technology, is changing how homeowners experience comfort. With a heating capacity down to -27°C and unmatched energy efficiency (22 SEER), this machine is the ultimate fit for Quebec’s harsh winters and sweltering summers.
The Story Behind the Installation
Our Blainville clients were ready to upgrade their outdated system to something that matched their modern lifestyle and growing energy-conscious needs. After assessing the property and considering their requirements, our team recommended the SHARP ZU1 24,000 BTU heat pump—a model that delivers exceptional comfort without compromise.
Our team executed the project seamlessly, ensuring the exterior unit was securely mounted with proper clearance and optimal drainage, while the interior unit was strategically placed for maximum efficiency and airflow distribution. Precision, expertise, and care guided us every step of the way.
Why the SHARP ZU1 24,000 BTU is the Perfect Choice
Unmatched Heating and Cooling Performance
The SHARP ZU1 isn’t just any wall-mounted heat pump; it’s an elite performer. It heats efficiently even at outdoor temperatures as low as -27°C, making it perfect for Blainville’s unpredictable winters. With a cooling capacity of 24,000 BTU, it also delivers fresh, consistent airflow during hot summer months.
State-of-the-Art Plasmacluster Technology
Indoor air quality is critical, and SHARP’s exclusive Plasmacluster™ technology sets this system apart. This unique feature neutralizes airborne viruses, bacteria, allergens, and mold spores, providing cleaner, healthier air throughout the home. With this advanced purification, families breathe easy knowing they are protected.
Key Benefits of Plasmacluster:
- Eliminates airborne contaminants.
- Reduces mold and odors.
- Neutralizes allergens and smoke residue.
The Coanda Airflow Effect
No one wants cold or hot air blowing directly onto them, which is why SHARP’s Coanda airflow control is such a game-changer. Inspired by natural fluid dynamics, this technology gently directs air upward during cooling and downward during heating, ensuring uniform temperature distribution.
Why it matters:
- No drafts or discomfort.
- Even temperature control across the entire room.
- Reduces energy waste by targeting strategic surfaces.
Eco-Friendly and Energy-Efficient
As HVAC specialists, we understand the importance of sustainability. The SHARP ZU1 uses the innovative R-32 refrigerant, which is not only more efficient but also drastically reduces greenhouse gas emissions compared to older refrigerants like R-22. This refrigerant supports environmental conservation without sacrificing performance.
Energy Savings with Inverter Technology
The ZU1’s inverter compressor ensures energy efficiency by maintaining consistent airflow without frequent stops and restarts. This smart operation reduces energy bills while keeping your home at the ideal temperature.
Technical Highlights:
- 22 SEER Efficiency: Maximum savings on energy bills.
- Noise Levels: 25 dB(A) indoors for whisper-quiet operation.
- Warranty: Industry-leading 10-10-10 warranty covering compressor, parts, and labor.
Seamless Installation in Blainville: Attention to Detail
Installing a 24,000 BTU wall-mounted heat pump requires precision, especially when working with cutting-edge equipment like the SHARP ZU1. At AirGreen, we ensure that every installation meets the highest industry standards.
- Exterior Placement: Mounted securely to the home’s façade, ensuring proper drainage and noise reduction.
- Interior Positioning: Optimized for maximum airflow and Plasmacluster distribution.
- Connectivity: Integrated Wi-Fi capabilities allow our clients to control their system remotely.
LogisVert Grant: A $2,688 Advantage
We understand the importance of affordability for Quebec homeowners. The SHARP ZU1 is eligible for the $2,688 LogisVert grant offered by Hydro-Québec. This substantial incentive makes upgrading to this energy-efficient heat pump an even more attractive option.

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.
