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.
Enhancing Comfort and Efficiency with a SHARP BU Double Zone Heat Pump in Plateau-Mont-Royal
A Fresh Start for Comfort and Air Quality in Montreal Homes

This SHARP BU Double Zone Heat Pump installation in Plateau-Mont-Royal perfectly demonstrates our dedication to top-tier service, energy efficiency, and customer satisfaction.
The Project: A Modern Solution for a Classic Plateau Home
Nestled in the heart of Plateau-Mont-Royal, one of Montreal's most iconic neighborhoods, this charming residence was ready for a major upgrade. The homeowners reached out to us, seeking a system that could effectively heat and cool their home across two distinct zones while meeting their long-term energy-saving goals.
With the region’s diverse climate—hot summers and freezing winters—it was essential to choose a system that offered both high performance and reliability in extreme weather conditions. The SHARP BU Double Zone Heat Pump emerged as the clear choice.

Installation Details: Precision and Care
Our team worked diligently to ensure this installation met the highest standards.
Step 1: Strategic Placement of Indoor Units
The two 12,000 BTU indoor units were positioned carefully to maximize airflow efficiency while complementing the aesthetics of the home. One unit was installed in the living room, where family members gather, ensuring a comfortable environment year-round. The second unit was placed in the bedroom, guaranteeing restful nights no matter the season.
Step 2: Exterior Unit Installation
The 24,000 BTU outdoor compressor was installed with precision, ensuring optimal operation even in frigid Montreal winters. This unit, boasting SHARP’s patented “HOT GAS PIPE” system, prevents ice buildup and maintains high efficiency at temperatures as low as -27°C—essential for homes in Quebec’s unpredictable winters.
Step 3: Custom Piping and Finishing
Attention to detail matters. Our team used clean, discrete piping to connect the indoor and outdoor units, blending seamlessly into the home’s architecture. We take pride in ensuring that our installations look as good as they perform.

Among the year’s most efficient according to ENERGY STAR, on top of its cold-climate certification.
Minimum certified capacity (NEEP): it slows down instead of stopping when a single room calls.
NEEP still lists 14,600 BTU/h at a COP of 1.84 at −17 °F.

The big day, step by step
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 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.
