Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
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.
Bringing Year-Round Comfort to Rosemont–La Petite-Patrie
In one of the charming neighborhoods of Montreal, Rosemont–La Petite-Patrie, AirGreen recently completed an impressive installation of a Sharp ZU1 15,000 BTU mini split heat pump. This project not only brought a modern heating and cooling solution to the homeowners but also aligned perfectly with Hydro-Québec’s LogisVert grant for energy-efficient equipment, offering them a $2,172 rebate.
Our team at AirGreen takes pride in every installation, but this one in particular highlights how the right equipment and professional installation can make a real difference in home comfort—even in the harshest conditions.
Why the Sharp ZU1 is a Game-Changer for This Project
The Sharp ZU1 15,000 BTU heat pump is the first of its kind to use the innovative R-32 refrigerant, making it not only environmentally friendly but also future-proof with upcoming regulations. What makes this machine stand out from its competitors is its exceptional heating capacity, performing flawlessly down to an incredible -27°C. Perfect for Montreal’s icy winters, this unit ensures that no matter how cold it gets outside, the home stays cozy and warm inside.
Key Features of the Sharp ZU1 Mini Split Heat Pump:
- Cooling Capacity: 15,000 BTU
- Heating Capacity: Operates down to -27°C
- Energy Efficiency Rating: 24.0 SEER, making it one of the most efficient units on the market
- WiFi Connectivity: Control your unit remotely via your smartphone
- Plasmacluster Technology: Unique to Sharp, this feature purifies the air by eliminating allergens, mold, and viruses
With these standout features, it’s clear that the Sharp ZU1 is built not just for performance but for enhancing indoor air quality and energy savings.
The Story Behind the Installation: Tailoring Comfort to a Modern Home
This particular installation took place in a home that had previously relied on older, less efficient heating solutions. The homeowners were looking for an upgrade that would not only reduce their energy bills but also provide year-round comfort without sacrificing performance in extreme weather conditions.
After careful consultation, we recommended the Sharp ZU1 mini split system, as it offered the perfect balance of efficiency, power, and indoor air quality improvement. Given that the machine qualifies for both provincial and federal grants, the investment was an easy decision for the homeowners.
One of the unique aspects of this installation was the layout of the home. The Coanda airflow control feature of the Sharp ZU1 allowed us to optimize air distribution throughout the house, ensuring every room received uniform heating and cooling. This feature, coupled with the Plasmacluster technology, ensured that the air circulating inside the home was as clean and fresh as it was comfortable.
Installation Details: Precision, Performance, and Perfection
Our team worked meticulously to ensure that every aspect of the installation met our high standards. The indoor unit, with dimensions of 41.42 x 9.80 x 12.44 inches, was installed in the living area, strategically placed for maximum efficiency and airflow. Its sleek design blended seamlessly into the modern décor, offering both form and function.
For the exterior unit, which measured 30.72 x 10.59 x 21.25 inches, we chose a spot that allowed for optimal ventilation while minimizing sound levels. With an exterior noise level of only 49.0 dB(A), the homeowners were pleasantly surprised by how quiet the system was, even when operating at full capacity.
The installation also involved running new pipes—1/4" for liquid and 3/8" for gas—and wiring the system to a 220V power source. We ensured everything was properly insulated and secured, leaving the home with a clean, professional finish. This attention to detail is why AirGreen is a trusted name in HVAC installations across Montreal, Laval, Longueuil, North Shore, and South Shore.
Benefits of the Sharp ZU1 Heat Pump: More Than Just Temperature Control
Installing the Sharp ZU1 offers homeowners much more than simple temperature control. This mini split system is designed to provide:
- Superior Air Quality: With Plasmacluster technology, the air inside the home is purified of allergens, mold, viruses, and odors.
- Energy Savings: The unit’s high 24.0 SEER efficiency rating means lower energy consumption, which translates into reduced utility bills for the homeowners.
- Environmentally Friendly Refrigerant: The R-32 refrigerant used in this unit has a significantly lower global warming potential compared to traditional refrigerants, making it a more sustainable choice.
- Smart Technology: With WiFi connectivity, the homeowners can control the system from anywhere, ensuring their home is always at the perfect temperature.
A Future-Proof Investment with Government Support
In addition to the $2,172 provincial grant, this installation also qualified for a $2,500 federal grant, helping the homeowners significantly offset the initial cost. These grants are part of broader efforts by the government to encourage energy-efficient upgrades, making now the perfect time for homeowners to invest in systems like the Sharp ZU1.
By choosing this model, our clients in Rosemont–La Petite-Patrie not only improved their home’s comfort but also made a smart financial decision that will continue to pay dividends for years to come.

What would it look like 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.

Your own project, step by step
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
Is your home ready?
Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
