Why Dollard-des-Ormeaux? The Perfect Place for a TripleZone System
Dollard-des-Ormeaux, located in the heart of Montreal’s West Island, is known for its diverse weather patterns. This residence required a system capable of delivering consistent heating and cooling, no matter the external conditions. The TripleZone model was the perfect fit, given its adaptability and high efficiency. Our client, keen on creating a comfortable living environment while keeping energy costs low, opted for this solution after evaluating several options.
Detailed Installation Overview
Exterior Unit Specifications
- Model: AE-X3M24BU
- Dimensions: 33.47 x 13 x 27.94 inches
- Sound Pressure Level: 50.0 dB(A)
- Gas: R-32
- Voltage: 220V
The exterior unit was strategically placed to minimize noise while maximizing performance. With its compact design and sound pressure level of only 50 dB(A), it is exceptionally quiet, making it suitable for residential neighborhoods like Dollard-des-Ormeaux. The unit’s design ensures effective cooling and heating distribution throughout the home.
Interior Units Specifications
- Interior Model Numbers: AY-XPC9BU, AY-XPC12BU, and AY-XPC18BU
- Zones: Three zones, each managed by a 9,000 BTU indoor unit
- Smart Controls: Wi-Fi-enabled, allowing seamless operation from mobile devices
The indoor units were strategically positioned to cover the living room, master bedroom, and home office—each receiving an individual unit for customized temperature control. The sleek design of these units complemented the home’s interior while providing discreet but effective climate control.
Eco-Friendly Advantages: R-32 Refrigerant
One of the standout features of this installation is the use of R-32 refrigerant, a more sustainable option compared to traditional refrigerants like R-410A. R-32 is not only more efficient but also has a lower Global Warming Potential (GWP), reducing the overall carbon footprint of the home’s HVAC system.
This choice aligns with AirGreen’s commitment to offering eco-conscious solutions, allowing homeowners to reduce their impact on the environment without sacrificing comfort.
Plasmacluster Technology for Superior Indoor Air Quality
Another highlight of the Sharp BU TripleZone model is its Plasmacluster technology, which enhances indoor air quality. This feature emits positive and negative ions, similar to those found in nature, to help neutralize viruses, bacteria, and allergens.
Benefits of Plasmacluster Technology:
- Healthier Air: Reduces airborne pathogens, contributing to better respiratory health.
- Odor Control: Effectively neutralizes odors, ensuring fresh-smelling indoor air.
- Allergy Relief: Helps in reducing allergens, making it an excellent choice for households with allergy sufferers.
Energy Efficiency and Cost Savings
With an impressive 24.0 SEER rating, the Sharp BU TripleZone is designed to be one of the most energy-efficient models on the market. This rating ensures significant savings on electricity bills, especially during peak heating and cooling months. For the homeowner in Dollard-des-Ormeaux, this means a more comfortable home without the stress of high energy costs.
Additionally, this model qualifies for the $3,000 LogisVert grant by Hydro-Québec, further reducing the initial installation costs and making it an economically sound investment.
Winter Performance: Heating Down to -27°C
The Sharp BU TripleZone was selected not only for its cooling capacity but also for its exceptional heating performance. With the ability to operate efficiently in temperatures as low as -27°C, this heat pump is built for Montreal’s severe winters. Its patented Hot Gas Pipe system minimizes heat loss during defrost cycles, ensuring a consistent indoor temperature even in the coldest conditions.
How It Works:
- Defrost Cycle Efficiency: Utilizes residual heat to prevent ice buildup on the exterior unit, maintaining heating efficiency.
- Reduced Heat Loss: The innovative design minimizes energy waste, contributing to overall cost savings and enhanced comfort.
Quiet Operation for Peaceful Living
A common concern with HVAC systems is noise, especially in quiet residential areas like Dollard-des-Ormeaux. The Sharp BU TripleZone Heat Pump is engineered for whisper-quiet operation, both indoors and outdoors. With a noise level of just 50 dB(A), it’s as quiet as a normal conversation, allowing homeowners to enjoy a peaceful living environment.

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.
