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.
Transforming Home Comfort with the SHARP BU Double-Zone Heat Pump
In the vibrant and dynamic suburb of Dollard-des-Ormeaux, our team at AirGreen recently completed a remarkable HVAC installation. We had the privilege of equipping a home with the SHARP BU Double-Zone Heat Pump, a cutting-edge system designed for optimal comfort and efficiency. With its advanced features and robust performance, this installation was not just a routine task but a step towards redefining home heating and cooling for our client.
Why the SHARP BU Double-Zone Heat Pump Stands Out
This installation features the SHARP BU 24,000 BTU compressor, paired with two 12,000 BTU indoor units, creating a perfectly balanced system to manage distinct zones within the home. The SHARP BU is more than a heat pump; it's an energy-efficient, environmentally conscious solution tailored for Quebec's fluctuating climate.
Key Features of the SHARP BU Heat Pump
- Cooling Capacity: A robust 24,000 BTU capacity ensures exceptional cooling during even the hottest summers.
- Heating Performance: Operating efficiently in temperatures as low as -27°C, this system is a reliable ally against Montreal's harsh winters.
- Efficiency Rating: With an impressive 24.0 SEER, this model guarantees energy savings while maintaining optimal performance.
- WiFi Connectivity: The built-in WiFi module allows seamless control from your smartphone or other devices.
- Environmental Responsibility: Powered by the eco-friendly R-32 refrigerant, the SHARP BU aligns with global sustainability goals.
The Installation Process: Tailored Precision in Dollard-des-Ormeaux
The installation was strategically planned to enhance both functionality and aesthetics. The exterior unit, measuring 33.47 x 13 x 27.94 inches, was securely mounted on a sturdy bracket to ensure stability and minimize vibrations. Inside the home, the two 12,000 BTU indoor units were placed in key areas to provide maximum comfort for the family.
Our technicians paid meticulous attention to every detail, from aligning the units to ensuring optimal airflow. The exterior unit was installed at a height that protects it from snow accumulation, a critical factor given Montreal's snowy winters. The piping and wiring were neatly organized, maintaining the home’s visual appeal.
The Benefits of a Double-Zone System
The SHARP BU's double-zone capability allows homeowners to customize temperatures in two separate areas of the house. Whether it's a cozy bedroom or a bustling living room, each space can have its ideal climate, ensuring unparalleled comfort.
- Enhanced Comfort: Tailor the climate in different areas based on preferences or usage.
- Energy Efficiency: By targeting specific zones, homeowners avoid wasting energy on unoccupied spaces.
- Flexibility: The system is designed to handle up to three zones, offering the potential for future expansion.
Admissible for a $3,000 LogisVert Grant
One of the highlights of this project is that the SHARP BU model qualifies for the $3,000 LogisVert Grant by Hydro-Québec. This grant significantly offsets the installation cost, making it a financially savvy choice for homeowners. By investing in this high-efficiency system, the client not only enjoys long-term savings on energy bills but also contributes to a greener future.
Durability and Innovation: Built to Last
The SHARP BU Heat Pump comes with a comprehensive 10-10-10 warranty—10 years on the compressor, parts, and labor. This ensures peace of mind for our clients, knowing their investment is protected. Moreover, the 50.0 dB(A) sound pressure level of the exterior unit ensures quiet operation, making it ideal for residential areas.
Patented "Hot Gas Pipe" Technology
Unique to SHARP, this feature ensures consistent performance even during extreme winter conditions. By preventing ice buildup on the exterior unit, the system remains efficient and reliable, regardless of the weather.
Client Feedback: A Happy Homeowner
The homeowner was thrilled with the results, particularly the system's quiet operation and the ability to control it remotely via WiFi. They noted an immediate improvement in air quality and overall comfort, expressing gratitude for our team's professionalism and attention to detail.

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.
