A black wall-mounted heat pump designed for the Quebec climate

At AirGreen, we install wall-mounted heat pumps throughout Montreal, Laval, Longueuil, and on the North and South Shores . The SHARP CU-B Black 15,000 BTU has quickly established itself as a strategic choice for homeowners who want to combine heating performance down to -30°C , distinctive design, and certified energy efficiency.

The AY-XP15CU-B indoor unit paired with the AE-X15CU outdoor unit (AHRI 217508926) is designed to withstand Quebec's harsh winters while providing precise air conditioning comfort during the summer. It is an ENERGY STAR® Cold Climate system, eligible for the LogisVert grant ($2,172 – updated November 26, 2025) , making it a worthwhile investment in the medium and long term.

Actual heating performance down to -30°C: what this means in practice

Capacity and yield measured

The technical specifications confirm solid data:

• Rated capacity: 15,000 BTU

• Power at -8°C: 18,100 BTU

• Power at -15°C: 15,300 BTU

• Guaranteed operation down to -30°C

• COP at -8 °C: 12.13

• R-32 refrigerant

• SEER2: 24.0

• HSPF2: 11.0

In practice, this means that in Montreal or Laval , for a well-insulated condo of 800 to 1,200 sq ft, this unit can cover the majority of heating needs without constant recourse to an electric backup.

We recently installed this model in a triplex in Longueuil (Old Longueuil sector) . The client previously used electric baseboard heaters as their primary heating source. After installation, winter energy consumption decreased by approximately 35% during January and February, while maintaining a stable temperature of 21°C even during a cold snap below -20°C.

Hot Gas Pipe Technology: Intelligent freeze protection

The AE-X15CU outdoor unit features a Hot Gas Pipe defrosting system, which reuses the generated heat to prevent excessive freezing of the coil. Unlike some entry-level systems, it does not have a separate, energy-intensive electric heating element.

For properties on the North Shore , exposed to more direct winds, this technology ensures increased stability and limits prolonged defrosting cycles.

Optimized air distribution: uniform comfort without unpleasant drafts

Coanda Airflow – range up to 50 feet

The CHU/CU series incorporates Coanda Airflow technology. In cooling mode, air is projected towards the ceiling, along the surface, and then gradually descends. In heating mode, the airflow is directed towards the floor.

Result :

• Less sensation of direct current

• Better heat distribution

• Consistent comfort in open spaces

In a bungalow in Laval (Chomedey) , we installed this unit in a living room open to the dining room. Thanks to this technology, the heat spreads efficiently into the adjacent hallway, reducing the need for a second unit.

Multi-Space Function

The Multi Space function optimizes circulation to connected rooms (hallway, mezzanine, open area). This is particularly relevant for open-concept condos in Montreal (Plateau, Rosemont, Griffintown) .

Precision of the shutters

• Automatic vertical shutter

• Manual horizontal adjustment

Important: Unlike the CHU series, the CU-B series does not have a motion sensor or automatic left-right adjustment . This distinction is crucial to avoid confusion when choosing the model.

Energy efficiency and R-32 refrigerant: a responsible choice

The SHARP CU-B Black 15,000 BTU operates with R-32 refrigerant, known for:

• Its global warming potential is lower than that of R-410A

• Its improved thermal efficiency

• A reduced refrigerant charge

In a context where homeowners in Boucherville, Brossard or Terrebonne are seeking to reduce their energy footprint, this criterion becomes crucial.

The unit is ENERGY STAR® and Cold Climate certified, which confirms its compliance with North American performance standards in severe winter conditions.

Noise level: an often underestimated criterion

• Indoor unit: 23 to 46 dB(A)

• Outdoor unit: 50 dB(A)

At 23 dB(A), the level is comparable to a slight hum. For a bedroom or home office, this changes the daily experience.

We installed this model in a condo in Ville-Marie where the client worked remotely. Its quiet operation was a deciding factor compared to other brands we tested.

WiFi connectivity and smart control

The heat pump includes built-in WiFi and the SHARP AIR mobile app:

• Remote adjustment

• Timetable

• Consumption tracking

• Maintenance alerts

For owners of second homes on the South Shore , this allows the property to be preheated before arrival, optimizing comfort and energy management.

Professional HVAC Installation: What Makes the Difference

Key technical specifications

• Voltage: 220V

• MOP: 20A

• Piping: 1/4 – 3/8 in

• Interior dimensions: 41.42 x 9.80 x 12.44 in

• External dimensions: 30.72 x 10.59 x 21.25 in

At AirGreen, each HVAC installation includes:

1. Electrical panel check

2. Installation of the dedicated circuit breaker

3. Anti-vibration wall mount or base

4. Complete vacuum sealing

5. Leak test and calibration

We carry $5,000,000 in liability insurance and operate under RBQ license #5645-9605-01 .

Simplified HVAC maintenance: practical design

The series includes:

• After Care function to dry the indoor unit after use

• Easy access to filters

• Simplified diagnostics for technicians

During our annual HVAC maintenance in Montreal and Laval , this model stands out for its speed of cleaning and stability of performance after 2 to 3 years of use.

Distinctive black design: successful architectural integration

The matte black finish is particularly popular in:

• Modern lofts

• Minimalist decor

• The dark accent walls

In Boucherville , a client replaced a standard white unit to harmonize the aesthetics of their contemporary living room. The visual impact is significant without compromising performance.

Guarantee and peace of mind

• 10-year compressor warranty

• 10-year parts warranty

• 0 years standard labor (extension option available)

At AirGreen, we offer labor warranty extensions to secure your investment.
