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.
A High-Efficiency Heat Pump: Tailored for Montreal's Unique Climate
At AirGreen, we take pride in transforming home comfort for our clients, and our recent installation of a Sharp BU TripleZone heat pump in Rosemont, Montreal, is a prime example of our dedication to excellence. This installation reflects the best in HVAC technology, offering advanced features, energy efficiency, and comfort for all seasons.
Why Choose the Sharp BU TripleZone Heat Pump?
The Sharp BU TripleZone heat pump is built to provide tailored comfort across different zones of a home. It’s designed for Montreal’s fluctuating weather, ensuring warmth during harsh winters and refreshing coolness in the hot summers. The model we installed is a 24,000 BTU compressor, which is connected to three indoor units, each with a 9,000 BTU capacity. This configuration is optimal for homes with multiple rooms requiring independent temperature control, providing consistent comfort throughout the residence.
Key Features of the Sharp BU TripleZone
Energy Efficiency Meets High Performance
- Cooling Capacity: 24,000 BTU
- Heating Capacity: Up to -27°C, ensuring reliable performance even in severe winter conditions
- Efficiency Rating: 24.0 SEER (Seasonal Energy Efficiency Ratio), highlighting its top-tier energy-saving capabilities
- WiFi Connectivity: Allows remote control and monitoring, offering convenience and enhanced energy management
This heat pump is Energy Star® certified, which means it not only reduces energy bills but also contributes to a lower environmental footprint. Furthermore, the unit operates using R-32 refrigerant, known for its lower Global Warming Potential (GWP), making it a more sustainable choice compared to traditional options.
Installation Details in Rosemont
Tailored Installation to Maximize Performance
The Rosemont project was particularly interesting due to the specific requirements of the building’s layout. The installation involved positioning the Sharp BU TripleZone’s outdoor compressor on a sturdy platform on the roof. This approach ensured the unit was elevated, offering optimal airflow and minimizing exposure to potential obstructions.
Each of the three indoor units was strategically placed:
- First Unit: Installed in the living room for a cool and comfortable main area.
- Second Unit: Located in the master bedroom to maintain a pleasant sleeping environment.
- Third Unit: Positioned in the home office, ensuring a comfortable work-from-home setup.
These zones were chosen based on the homeowner's needs for independent climate control in different parts of the home, offering flexibility and personalized comfort.
The LogisVert Grant: An Added Bonus
Residents of Quebec can benefit from the LogisVert grant provided by Hydro-Québec. This $3,000 grant is available for homes upgrading to energy-efficient systems like the Sharp BU TripleZone heat pump. Our client in Rosemont qualified for this grant, reducing the overall cost of the installation and making the upgrade more affordable.
Unique Technologies for Ultimate Comfort
Plasmacluster: Improving Indoor Air Quality
The Plasmacluster technology, exclusive to Sharp, is integrated into the TripleZone model to enhance indoor air quality. This technology emits positive and negative ions that neutralize airborne bacteria, viruses, and allergens. Not only does it ensure a healthier indoor environment, but it also helps eliminate odors, keeping the air fresh and clean.
Coanda Effect: Even Airflow Distribution
One of the standout features of this heat pump is the Coanda effect, which allows for even distribution of air across the room. Unlike traditional systems that direct air in one direction, this technology ensures that conditioned air travels along walls and ceilings, avoiding direct drafts on occupants. The result is a more natural and comfortable indoor climate.
Hot Gas Pipe System: Superior Winter Performance
Montreal winters can be brutal, but the Hot Gas Pipe system of the Sharp BU ensures uninterrupted performance even during the coldest days. This technology retains residual heat from defrost cycles, preventing ice buildup on the outdoor unit and maximizing efficiency even at temperatures as low as -27°C.

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.

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.
