Installation of a SHARP BU DoubleZone Wall-Mounted Heat Pump in Côte Saint-Luc

A custom HVAC project for year-round comfort in Côte Saint-Luc

At AirGreen, we believe every wall-mounted heat pump installation is an opportunity to create lasting, energy-efficient, and intelligent comfort for our clients. Recently, we had the privilege of completing an HVAC installation in Côte Saint-Luc, in the west end of the Island of Montreal, where we installed a SHARP BU DoubleZone wall-mounted heat pump, a premium solution for homes requiring independent heating and cooling management across multiple zones.

This project showcases our expertise in residential HVAC, our attention to detail, and our ability to deliver high-quality Japanese products tailored to the unique climate challenges of Quebec.

Why choose the SHARP BU DoubleZone? A perfect fit for Côte Saint-Luc

The SHARP BU DoubleZone wall-mounted heat pump is specifically designed to meet the needs of homes that want to control two separate zones with a single outdoor unit. It’s a multizone system, ENERGY STAR certified, offering not only high energy efficiency but also integrated air purification thanks to SHARP’s exclusive Plasmacluster technology.

Key technical features of the SHARP BU DoubleZone:

• Outdoor unit: AE-X3M24BU

• Capacity: 24,000 BTU cooling / 26,000 BTU heating

• Performance down to -27°C, thanks to Hot Gas Pipe technology

• R-32 refrigerant, eco-friendly and efficient

• Minimal noise level (49–50 dB outdoor)

• Two AY-XPC12BU indoor units with strong airflow (438 CFM)

• Compact dimensions: ideal for residential wall-mounted setups

Thanks to its inverter technology, this system quickly reaches the desired temperature in both zones while significantly reducing energy consumption once that temperature is achieved.

A well-planned installation in Côte Saint-Luc

This project was completed in a renovated bungalow in Côte Saint-Luc, where the homeowners were looking to upgrade their heating system while adding cooling capabilities for summer.

Here are the key steps of our installation:

1. Evaluating the client’s needs

We carried out a comprehensive thermal analysis of the two areas to be conditioned: the main living room on the ground floor and the family room in the basement. Each space required independent capacity for optimal comfort.

2. Strategic placement

The outdoor unit was installed on reinforced wall mounts at the back of the house, to minimize noise and ensure proper clearance. Thanks to smart planning, the unit doesn’t interfere with foot traffic or the home’s aesthetics.

3. Installing the indoor units

Two AY-XPC12BU wall-mounted units, sleek and discreet, were installed strategically:

• One in the basement family room, with optimized frost protection clearance

• One in the main living room, mounted high to maximize airflow

4. Connections and commissioning

We installed insulated copper refrigerant lines, protected electrical connections, and gravity-fed drainage in full compliance with all standards. We then conducted a nitrogen pressure test, a vacuum test, and performed a full R-32 refrigerant charge with care and precision.

5. Calibration, testing, and client training

After completing performance testing, we took the time to show the client how to use the remote control, configure smart scheduling, and take advantage of the eco-friendly mode and Plasmacluster air purification system.

Tangible benefits for the client

This Côte Saint-Luc family now enjoys:

• Comfort across two floors (basement and main level)

• Significant energy savings on their electric bill

• Cleaner indoor air, thanks to the triple filtration system: HEPA filter, activated carbon, and Plasmacluster ion technology

• A quiet, reliable unit built for Quebec’s extreme climate

A heat pump built for Quebec: performance down to -27°C

The AE-X3M24BU model truly stands out for its ability to heat effectively even in frigid temperatures. Thanks to SHARP’s exclusive Hot Gas Pipe system, defrosting is faster, more complete, and doesn’t compromise the unit’s overall efficiency.

Here are some heating performance numbers:

• -8.3°C: 25,000 BTU/h

• -15°C: 21,200 BTU/h

• -20°C: 18,600 BTU/h

• -25°C: 15,700 BTU/h

• -27°C: 14,600 BTU/h
