Installation of a Sharp ZHU1 12,000 BTU Heat Pump in Laval
Discover how AirGreen’s expert installation of the Sharp ZHU1 heat pump in Laval ensures year-round comfort, incredible energy savings, and eligibility for the Hydro-Québec LogisVert Grant.
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.
Expert Installation of a Sharp ZHU1 Heat Pump in Laval
When it comes to choosing an HVAC system, homeowners in Laval are increasingly turning to AirGreen for reliable, energy-efficient solutions. In our latest project, we had the pleasure of installing the Sharp ZHU1 12,000 BTU Heat Pump, an advanced system designed to keep homes comfortable through the harshest Quebec winters and hottest summers.
A Heat Pump Built for Quebec's Climate
The Sharp ZHU1 is no ordinary heat pump—it’s a system tailored to meet the unique demands of Quebec’s extreme weather conditions. This high-efficiency heat pump is capable of operating at temperatures as low as -27°C, ensuring your home stays warm even during those deep winter freezes.
What sets this model apart is its Energy Star® certification, meaning it adheres to strict energy efficiency guidelines, helping homeowners save on energy bills while also reducing their carbon footprint. With an impressive 25.0 SEER rating, it is one of the most energy-efficient systems available on the market today.
Key Features of the Sharp ZHU1 Heat Pump:
- WiFi connectivity: Control your home’s temperature from anywhere with an easy-to-use app.
- Low noise operation: Indoor noise levels between 22 dB and 44 dB make it quieter than many competing models.
- Powerful cooling and heating capabilities: 12,000 BTU cooling capacity and strong heating performance down to -27°C.
- Environmentally friendly refrigerant: Uses R-32 refrigerant, which is not only more efficient but also reduces greenhouse gas emissions by up to 10%.
- 10-10-10 Warranty: Enjoy peace of mind with 10 years on the compressor, parts, and labor.
The Installation Process: A Professional Approach
At AirGreen, we understand that a quality heat pump requires not only a superior product but also precise installation. For this project in Laval, our team began by evaluating the layout of the home to determine the optimal placement for both the indoor unit and the outdoor compressor. The Sharp ZHU1 is a compact unit, making it ideal for urban homes where space is limited, and its sleek design fits seamlessly with modern aesthetics.
We took care to ensure the piping was installed correctly, using 1/4 - 3/8-inch copper piping to guarantee efficient operation. The system operates at 220V, making it compatible with most residential electrical setups.
One of the more critical components of the installation was ensuring the outdoor unit would remain stable during the cold winter months. By mounting it on a reinforced steel frame, we ensured the unit would stay secure and efficient, even in heavy snowfall.
Fine-Tuning for Optimal Performance
Once the system was physically installed, our technicians calibrated the heat pump to ensure it was running at peak efficiency. Using the AHRI certification (213238803) as a benchmark, we tested the system’s performance in both heating and cooling modes. The 49 dB(A) outdoor noise level was well within acceptable limits, ensuring the unit would not disturb the neighbors, a frequent concern in denser neighborhoods.
Maximizing Savings with Hydro-Québec's LogisVert Grant
One of the major advantages of installing the Sharp ZHU1 heat pump is its eligibility for Hydro-Québec’s LogisVert Grant, which offers up to $2,268 in savings. This grant is designed to incentivize homeowners to switch to more energy-efficient systems, making the Sharp ZHU1 an even more attractive option for budget-conscious customers.
At AirGreen, we assist our clients in navigating the application process for the LogisVert grant, ensuring they get the full financial benefits available to them. This, combined with the long-term energy savings from the Energy Star® certification, makes the Sharp ZHU1 an unbeatable value proposition.

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.
