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.
Maximizing Comfort and Efficiency in Every Room
At AirGreen, we specialize in high-quality HVAC installations designed to meet the specific needs of homes across Montréal, Laval, Longueuil, the North Shore, and South Shore. Our recent project in Laval showcases our commitment to energy efficiency, environmental responsibility, and unparalleled indoor comfort. In this installation, we outfitted a home with a Sharp BU Triple Zone Heat Pump, a cutting-edge system designed to heat and cool up to three different zones independently, offering maximum flexibility and savings for homeowners.
Overview of the Installation
This particular home in Laval required a versatile solution that could maintain optimal comfort levels in multiple areas of the house, regardless of the season. With our expertise, we selected the Sharp BU Triple Zone Heat Pump, which boasts a 24,000 BTU compressor paired with three indoor units, each with a 9,000 BTU capacity. This setup allows the homeowner to independently control the climate in up to three rooms, ensuring customized comfort throughout the year.
The Sharp BU system is ideal for the cold Canadian climate, as it continues to operate efficiently even at temperatures as low as -27°C, thanks to its Hot Gas Pipe system—a feature that prevents ice build-up on the outdoor unit. This ensures that the system remains reliable and functional during even the harshest winter days.
Key Features of the Sharp BU Triple Zone Heat Pump
- Heating Capacity: With the ability to operate down to -27°C, this system ensures year-round comfort, even in frigid winter conditions.
- Cooling Capacity: The 24,000 BTU compressor is more than capable of cooling the home efficiently during the summer months, providing relief from the heat without excessive energy consumption.
- Triple Zone Technology: Each of the three indoor units can be controlled independently, allowing the homeowner to set different temperatures in different rooms. This not only improves comfort but also enhances energy efficiency.
- Eco-Friendly Refrigerant: The Sharp BU system uses R-32 refrigerant, which is both more energy-efficient and environmentally friendly compared to older refrigerants like R-22 or R-410A.
- Plasmacluster Technology: This innovative feature purifies the air by emitting ions that neutralize bacteria, viruses, and allergens, significantly improving indoor air quality.
Why Choose a Triple Zone Heat Pump?
One of the primary advantages of a Triple Zone Heat Pump is its ability to heat or cool multiple areas of your home without having to install separate systems for each room. This installation in Laval is a prime example of how you can improve both comfort and efficiency with one comprehensive system. Whether it's your living room, bedrooms, or office space, each area can be maintained at the perfect temperature, tailored to the specific preferences of the occupants.
The independent control feature is particularly useful for larger homes, where heating and cooling requirements can vary between different rooms. For instance, you may want to keep your bedroom cooler at night while maintaining a warmer temperature in your living area. With the Sharp BU system, this kind of flexibility is built-in, providing comfort where it's needed most, when it's needed most.
Benefits of the R-32 Refrigerant
Environmental responsibility is a cornerstone of modern HVAC solutions, and the Sharp BU Triple Zone Heat Pump excels in this area by utilizing R-32 refrigerant. This refrigerant has a lower global warming potential (GWP) than its predecessors, making it a more sustainable choice for homeowners who are conscious of their environmental impact.
In addition to being eco-friendly, R-32 also improves the overall energy efficiency of the system. This means that the homeowner will experience lower energy bills while also contributing to a greener future.
Comfort, Quiet Operation, and Energy Savings
The homeowner in Laval was particularly impressed by the quiet operation of the Sharp BU system. With a sound pressure level of just 50 dB(A) for the outdoor unit, the system operates almost silently, ensuring that it doesn’t disrupt the peaceful atmosphere of the home.
Moreover, the high SEER rating of 24.0 is a testament to the system's efficiency. This Seasonal Energy Efficiency Ratio (SEER) ensures that the system maximizes cooling output while minimizing energy input, translating into significant cost savings for the homeowner over the long term.
Eligibility for Grants and Rebates
One of the most appealing aspects of this installation is the financial incentives available to the homeowner. The Sharp BU Triple Zone Heat Pump qualifies for multiple grants, including:
- Hydro-Québec’s LogisVert Grant: Offering up to $3,000 in rebates.
- Federal Grants: Up to $2,500 in additional savings through energy efficiency programs.
These grants not only reduce the upfront cost of the installation but also make it easier for homeowners to invest in energy-efficient solutions that benefit both their wallets and the environment.

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.
