A Custom Comfort Solution Tailored for Montréal-Nord Homes
When it comes to modern home comfort, we believe in delivering personalized solutions that fit our clients' unique needs. Recently, we completed the installation of a SHARP BU Double-Zone Heat Pump in Montréal-Nord, an exceptional system designed to perform optimally in Canada’s harsh climate while offering unmatched energy efficiency and comfort.
This cutting-edge heat pump features a 24,000 BTU compressor paired with two 12,000 BTU indoor units, perfectly suited for maintaining consistent temperatures across two distinct zones. With eligibility for the $3,000 LogisVert Grant by Hydro-Québec, this installation underscores our commitment to combining top-tier technology with affordability for our valued clients.
Why the SHARP BU Heat Pump Stands Out

Key Features:
- Heating Capacity: Operates seamlessly in temperatures as low as -27°C, ensuring warmth even in extreme winters.
- Cooling Capacity: Provides a robust 24,000 BTU cooling output for comfort during the hottest days.
- Zones: Supports two individual zones for personalized temperature control, with the flexibility to add a third zone if needed.
- Efficiency Rating: Delivers an impressive 24.0 SEER, ensuring reduced energy consumption and lower utility bills.
- WiFi Integration: Offers remote control convenience, enabling homeowners to manage their comfort from anywhere.
- Quiet Operation: Exterior sound pressure level of just 50.0 dB(A) ensures peaceful operation.
Installation Details and Challenges
Strategic Placement for Optimal Performance
In this project, we carefully installed the outdoor compressor unit, measuring 33.47 x 13 x 27.94 inches, in a shaded yet accessible location. This placement ensures efficient operation while simplifying maintenance. The two 12,000 BTU wall-mounted indoor units were strategically positioned to maximize air circulation and maintain uniform temperatures in the home’s living and sleeping areas.
Navigating Montréal-Nord’s Urban Landscape
Montréal-Nord homes often present unique challenges due to their compact spaces and proximity to neighboring properties. Our team conducted a detailed site assessment, accounting for factors like airflow dynamics, electrical accessibility, and noise reduction, ensuring a seamless installation that harmonizes with the home’s layout.
A Sustainable Choice
The SHARP BU system utilizes R-32 refrigerant, which has a significantly lower Global Warming Potential (GWP) compared to traditional refrigerants. This not only reduces the system’s environmental impact but also ensures compliance with modern sustainability standards.
Plasmacluster Technology: Clean Air, Always
The inclusion of Plasmacluster Ion Technology elevates this heat pump’s performance by providing continuous air purification. This advanced feature releases positive and negative ions that:
- Neutralize Allergens: Effectively reduce dust, pollen, and other allergens, making the home safer for residents with sensitivities.
- Eliminate Odors: Remove lingering odors from pets, cooking, or smoke, ensuring fresher indoor air.
- Combat Pathogens: Diminish airborne bacteria and viruses, fostering a healthier living environment.
Performance in Extreme Canadian Winters
One of the standout features of the SHARP BU Heat Pump is its patented "HOT GAS PIPE" system, designed specifically to handle harsh climates like those in Montréal-Nord. This innovation prevents ice buildup on the outdoor unit, ensuring uninterrupted operation and peak efficiency during freezing conditions.
Why This Matters
For homeowners in Montréal-Nord, where winter temperatures can plunge well below freezing, the HOT GAS PIPE system eliminates the frustration of frequent defrost cycles and keeps the system running reliably.
Customer Benefits of the Installation
Energy Savings and Grants
Thanks to the 24.0 SEER rating and the environmentally friendly R-32 refrigerant, this SHARP BU heat pump offers substantial savings on energy bills. Additionally, the eligibility for the $3,000 LogisVert Grant further offsets the installation costs, making it a financially smart choice.
Enhanced Comfort and Convenience
With WiFi-enabled controls, homeowners can customize their comfort settings remotely. Whether it’s pre-warming the house during the commute home or cooling the bedrooms during a heatwave, this feature adds unmatched convenience.

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.

- 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.
