Installation of a SHARP ZU1 Wall-Mounted Heat Pump in Sainte-Marthe-sur-le-Lac
Discover how AirGreen brought year-round comfort to a Sainte-Marthe-sur-le-Lac home with the SHARP ZU1 Heat Pump—an efficient, eco-friendly solution for extreme weather!
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.

The Installation Process: Crafting Comfort
Step 1: Tailored Assessment
Our team began by analyzing the home’s layout and energy requirements. The goal was to ensure that the SHARP ZU1 would operate at peak efficiency while meeting the homeowner’s specific needs.
Step 2: Precision Installation
- The indoor unit, with its sleek design and dimensions of 41.42 x 9.80 x 12.44 inches, was carefully mounted to complement the interior decor while maximizing airflow.
- The outdoor unit, compact at 33.47 x 13 x 27.94 inches, was positioned strategically to optimize performance and minimize noise.
Step 3: Seamless Integration
Using high-quality pipes (1/4 - 3/8) and energy-efficient R-32 refrigerant, our technicians ensured a seamless connection between the indoor and outdoor units. The system was tested rigorously to guarantee optimal performance from day one.

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.
