Creating Unmatched Comfort in Lorraine with the SHARP BU Double Zone Heat Pump
In the heart of Lorraine, where winters can be unrelenting and summers warm, achieving year-round comfort is more than just a luxury—it’s a necessity. AirGreen recently completed the installation of a SHARP BU Double Zone Heat Pump with impressive precision, and the results speak for themselves. This 24,000 BTU powerhouse, equipped with a 9,000 BTU indoor unit for smaller spaces and an 18,000 BTU indoor unit for larger zones, offers tailored climate control at its finest.
Not only is this model eligible for the $3,000 LogisVert Grant by Hydro-Québec, but it also holds the top position in our Guide des Thermopompes Murales 2025 for its outstanding efficiency and reliability. The SHARP BU isn’t just another heat pump—it’s a statement of comfort, sustainability, and innovation.
Why the SHARP BU Double Zone Heat Pump Stands Out
When we first met the homeowners in Lorraine, they were looking for a solution that would balance comfort and energy efficiency across multiple zones in their home. Their needs were specific: customized climate control, reliable performance during harsh winters, and a future-proof, eco-friendly system.
The SHARP BU checked every box:
- Cooling Capacity: 24,000 BTU, perfect for tackling hot summer days.
- Heating Capacity: Operational down to -27°C, ensuring warmth even in Quebec’s coldest months.
- Efficiency: 24.0 SEER rating, delivering exceptional energy savings.
- Noise Levels: Ultra-quiet operation at just 50 dB(A) for the outdoor unit—so peaceful, you’ll forget it’s running.
- Zones: Two distinct zones with room for expansion (supports up to three zones).
What’s more, its use of R-32 refrigerant ensures reduced environmental impact without compromising on performance.
Installation Overview: A Tailored HVAC Solution
Breaking Down the Project
For this project, we installed:
-
Exterior Unit
- Model: AE-X3M24BU
- Dimensions: 33.47" x 13" x 27.94"
- Features: Energy Star® certified, WiFi-enabled for seamless remote control, and AHRI-certified for guaranteed performance.
-
Interior Units
- AY-XPC9BU (9,000 BTU): Perfect for smaller rooms like offices or bedrooms, providing targeted cooling and heating.
- AY-XPC18BU (18,000 BTU): Ideal for larger areas such as living rooms or open spaces, ensuring even temperature distribution.
Our expert technicians tackled the installation with precision, ensuring minimal disruption to the homeowners. With clean, well-routed piping and careful placement of the units, we maintained the aesthetic integrity of the home. The result? A sleek, modern HVAC system that blends seamlessly into the space while delivering superior performance.
Performance in Extreme Climates: Ready for Lorraine Winters
Quebec winters are no joke, and heat pumps often struggle in sub-zero temperatures. The SHARP BU, however, is built for the challenge. Thanks to its patented HOT GAS PIPE system, this model prevents ice buildup on the exterior unit, ensuring uninterrupted heating—even at a bone-chilling -27°C.
This was a key selling point for the homeowners, who needed a system that wouldn’t fail when the mercury dipped. With this installation, they can now enjoy cozy interiors without the worry of system breakdowns.
Advanced Features for Ultimate Convenience
WiFi Integration
The SHARP BU Heat Pump comes with built-in WiFi connectivity, allowing the homeowners to control the temperature zones directly from their smartphones. Whether they’re cozy in bed or out for the day, they can easily adjust their home’s climate for maximum comfort and efficiency.
Energy Efficiency You Can Count On
The combination of a 24.0 SEER rating and R-32 refrigerant makes this heat pump an eco-conscious choice. Compared to older refrigerants, R-32 has a significantly lower Global Warming Potential (GWP), aligning with Hydro-Québec’s energy-saving initiatives.
10-Year Warranty (Compressor, Parts, Labor)
With a 10-10-10 warranty, the SHARP BU offers homeowners peace of mind. From parts and labor to the compressor, this warranty reflects the unit’s unmatched durability and our commitment to long-term reliability.
A Grant-Eligible Solution: $3,000 LogisVert Grant
This installation also highlights the value of the Hydro-Québec LogisVert Grant, which offers homeowners up to $3,000 for installing energy-efficient heat pumps like the SHARP BU. Not only does this grant reduce the initial investment cost, but it also reinforces the importance of making sustainable choices for home comfort.
For homeowners in Lorraine and beyond, accessing this grant is an excellent way to invest in an HVAC system that delivers both performance and savings.

The job tools
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.
How the job unfolds
The main steps of this kind of job at AirGreen. Every house has its quirks: the estimate brings them out.
We look at the room, the outside wall, the line route and where the outdoor unit will go. That is where the capacity gets chosen.
Model, capacity and price, in writing. We also check whether the model qualifies for assistance programs.
Floors and furniture protected, wall plate position marked level, wall opening located.
A single opening, with the slope the drain needs to flow outside.
Set on a stand raised above the snow, with the clearances the manufacturer requires.
Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.
Remote, modes, filters: we show you the essentials before we leave.

What we check on a job like this one
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.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
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.
The right pages, at the right time
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.
