A Tailored Comfort Solution for Every Season
At AirGreen, we take pride in delivering HVAC solutions that go beyond simple climate control. This recent installation of a SHARP BU Double-Zone Heat Pump in the vibrant borough of Villeray–Saint-Michel–Parc-Extension is a testament to our dedication to combining performance, efficiency, and aesthetics. Featuring a 24,000 BTU compressor paired with two 12,000 BTU indoor units, this setup offers optimal comfort, unmatched energy savings, and a sleek, modern design.
A Closer Look at the SHARP BU Double-Zone Heat Pump
When it comes to ensuring year-round comfort, the SHARP BU heat pump is in a league of its own. Here's why this model is the perfect choice for Montreal's demanding climate:
- Heating Capacity: Reliable performance even at frigid temperatures as low as -27°C.
- Cooling Capacity: Effortless cooling with a capacity of 24,000 BTU, making it ideal for scorching summer days.
- Energy Efficiency: With a stellar 24.0 SEER rating, this system ensures low electricity consumption without compromising performance.
- Refrigerant: Equipped with R-32 refrigerant, the system boasts improved energy transfer, reduced environmental impact, and greater efficiency.
- Zones: This system supports two distinct zones, offering precise control over the temperature in different areas of the home, with a potential to expand to three zones if needed.
Why This Installation Stands Out
The homeowner in Villeray–Saint-Michel–Parc-Extension was looking for a heating and cooling solution that could address varying needs across two key areas of their home. The AirGreen team recommended the SHARP BU Double-Zone Heat Pump, a model perfectly suited to handle Montreal's temperature extremes while maintaining energy efficiency and environmental responsibility.
Custom Placement for Maximum Efficiency
To ensure optimal performance, we strategically placed the 24,000 BTU outdoor compressor in a well-ventilated location with easy access for future maintenance. The two indoor units, each with a capacity of 12,000 BTU, were carefully installed in high-traffic living spaces. Their placement ensures an even distribution of temperature and minimal disruption to the room’s aesthetics.
Noise-Free Operation
The SHARP BU is engineered for whisper-quiet performance, with the outdoor unit producing just 50 dB(A). This feature guarantees peace and tranquility, even during peak operation.
Grants and Energy Savings
One of the highlights of this installation is its eligibility for the $3,000 LogisVert Grant by Hydro-Québec. This significant financial incentive makes upgrading to energy-efficient systems like the SHARP BU not just environmentally smart but also economically rewarding.
The Energy Star® certification and high-efficiency operation mean lower monthly utility bills, allowing homeowners to recover their investment faster while reducing their carbon footprint.
Innovative Features of the SHARP BU Heat Pump
Plasmacluster Technology for Better Air Quality
Air purification is a cornerstone of the SHARP BU model. Its Plasmacluster technology releases positive and negative ions, neutralizing airborne particles like allergens, bacteria, and viruses. This ensures not just a comfortable but also a healthier indoor environment.
- Pathogen Neutralization: Reduction in airborne bacteria and viruses.
- Odor Control: Breaks down persistent odors, ensuring fresh indoor air.
- Allergy Relief: Filters out dust mites, pollen, and other common allergens.
Self-Cleaning Function
The SHARP BU system incorporates a self-cleaning mechanism that minimizes dust and mold accumulation, reducing maintenance needs and ensuring consistent performance over time.
Hot Gas Pipe System for Extreme Cold
Designed specifically for harsh winters, the hot gas pipe system prevents ice formation on the outdoor unit, maintaining efficient operation even in sub-zero temperatures.
WiFi Connectivity for Modern Convenience
With WiFi-enabled controls, the homeowner can easily manage their system remotely, fine-tuning temperature settings to match their schedule and preferences.

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.

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.
