Take a tour of the installation
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.
A Perfect Heating and Cooling Solution for Comfort and Savings
In Anjou, AirGreen recently completed the installation of a SHARP BU Double Zone Heat Pump, a high-performance 24,000 BTU system designed to deliver optimal comfort throughout all seasons. Equipped with two 12,000 BTU indoor units, this setup is tailor-made to efficiently manage temperatures across two distinct zones of the home. This installation offers not only exceptional comfort but also impressive energy savings and cutting-edge technology suited for Montreal’s climate extremes.
Why SHARP’s Double Zone Heat Pump Stands Out
The SHARP BU Double Zone Heat Pump is not just another air conditioning system; it’s an innovation that prioritizes efficiency, performance, and sustainability. Designed to operate flawlessly even in the coldest conditions, it is a top choice for homeowners in Montreal, Laval, Longueuil, and across the North Shore and South Shore.
Key Features of the SHARP BU Model
- Capacity: 24,000 BTU compressor with two 12,000 BTU interior units
- Heating Capability: Effective up to -27°C
- Energy Efficiency: 24.0 SEER (Seasonal Energy Efficiency Ratio)
- Refrigerant: R-32, eco-friendly with a low environmental impact
- Noise Level: 50.0 dB(A) for the exterior unit
- Smart Controls: Integrated WiFi for convenient management
- Warranty: 10 years on the compressor, parts, and labor
- Eligible for the $3,000 LogisVert Grant by Hydro-Québec
An Installation Designed for Montreal’s Climate
The SHARP BU is a year-round solution. In the winter, it heats homes reliably, even during frigid temperatures as low as -27°C, a necessity in Montreal's harsh winters. In summer, it provides refreshing, energy-efficient cooling. Whether you’re tackling sweltering July days or chilly February nights, this system keeps your home perfectly comfortable.
A Smooth and Professional Installation in Anjou
The installation took place in a residential home in Anjou, where our client needed a solution to manage temperatures in two primary zones of their home: the living room and master bedroom. With a SHARP 24,000 BTU outdoor compressor and two sleek, efficient 12,000 BTU indoor units, the system was ideal for their needs.
Our team at AirGreen approached the project with precision and care:
- Site Assessment: We ensured the location for the outdoor unit met optimal airflow requirements. Mounted securely on a concrete wall with vibration-dampening brackets, the unit was positioned to minimize noise and maximize longevity.
- Interior Units: The two wall-mounted units were placed strategically in the main living areas to ensure efficient airflow. Thanks to the Coanda Effect, these units direct air seamlessly, avoiding cold drafts and creating an even temperature across the zones.
- Electrical Setup: With a 220V system, we installed dedicated wiring to support the heat pump’s power demands, ensuring safe and smooth operation.
What Makes the SHARP BU a Top Choice?
Unmatched Air Quality with Plasmacluster Technology
One of the standout features of the SHARP BU series is its Plasmacluster ion technology, a game-changer for indoor air quality. By releasing positive and negative ions, it actively neutralizes viruses, bacteria, allergens, and even odors, ensuring the air you breathe is not only clean but also fresh.
For families in Anjou, especially those with allergies, asthma, or pets, this feature brings immense value.
Sustainability and Efficiency with R-32 Refrigerant
The choice of R-32 refrigerant ensures the system remains eco-friendly while providing superior performance. R-32 offers:
- Lower global warming potential (GWP) compared to traditional refrigerants
- Higher energy efficiency, leading to reduced electricity bills
- Recyclability, contributing to sustainability efforts
Ultra-Quiet Operation
Operating at just 50 dB(A), the SHARP outdoor compressor ensures peace and quiet for homeowners and their neighbors. Whether it’s running during a summer evening or a cold winter morning, the system operates silently in the background.
Energy Efficiency That Saves You Money
With a 24.0 SEER rating, the SHARP BU is among the most efficient heat pumps on the market. This translates into significant energy savings year-round, especially when compared to traditional HVAC systems.
Eligible for Hydro-Québec’s $3,000 LogisVert Grant
A major incentive for homeowners in Montreal and surrounding areas is the LogisVert Grant by Hydro-Québec. The SHARP BU heat pump qualifies for up to $3,000 in rebates, making this installation an investment that pays off quickly.
Combined with its 10-year warranty on parts, labor, and the compressor, the SHARP BU offers incredible value and long-term peace of mind.

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.
