SHARP CU Wall-Mounted Heat Pump | 12,000 BTU | R32 -27°C

A high-performance wall-mounted heat pump designed for Quebec winters

At AirGreen , we install hundreds of HVAC systems every year across Montreal, Laval, Longueuil, the North Shore and the South Shore . Quebec's climate imposes specific requirements: a unit must be reliable in periods of extreme cold, quiet in dense urban environments, and efficient in cooling during humid summers.

The SHARP CU 12,000 BTU R32 -27°C wall-mounted heat pump perfectly meets these criteria. This model, composed of the AY-XPC12CU indoor unit and the AE-X12CU outdoor unit, combines energy efficiency, proven cold-climate technology, and smart features adapted to Quebec homes.

Real-world performance down to -27°C: what this means in practice

In the field of residential HVAC heating , one piece of data is crucial: the ability to maintain heat when the temperature drops below -20°C.

Certified heating capacity in cold climates

• Rated capacity: 12,000 BTU

• Power at -8°C: 15,000 BTU

• Power at -15°C: 12,700 BTU

• Stable operation down to -27°C

• ENERGY STAR® Cold Climate Certification

• AHRI: 217512740

• R-32 refrigerant gas

In practical terms, this means that a 700 to 900 sq ft condo in Montreal or a duplex floor in Laval can be heated efficiently without constant use of electric baseboard heaters.

During an installation in Boucherville (South Shore) last January, the outside temperature was -24°C with strong winds. The client was replacing an old R-410A system that was ineffective below -18°C. After installing the SHARP CU, the indoor temperature stabilized at 21°C without any additional electric heating.

It is precisely this type of thermal stability that makes the difference in winter.

Coanda Airflow Technology: Optimized air diffusion

The CU series incorporates Coanda Airflow technology, allowing for an air projection that can reach approximately 50 feet.

How does this improve comfort?

• In air conditioning: the air is directed towards the ceiling to avoid a direct blow.

• In heating mode: the air is directed towards the floor to promote natural stratification.

Unlike some low-end units that project air directly onto the occupants, this system ensures a gentle and even distribution.

Important to note:
The CU series lacks the motion detector and automatic left-right scanning features reserved for the CHU series. Here, horizontal control is manual, which nevertheless allows for precise adjustment according to the room's configuration.

Measurable energy efficiency

Energy performance is essential to maximize the $1,800 LogisVert grant currently offered (updated November 2025).

Effectiveness indicators:

• SEER2: 21.0

• HSPF2: 11.0

• EER2: 12.5

• COP at -8°C: 2.13

This means that at -8°C, the device produces more than twice the thermal energy consumed in electricity.

In a triplex in Rosemont , we replaced an old direct electrical system with this SHARP 12,000 BTU unit. The result on the first Hydro-Québec bill: an average decrease of 28% in winter consumption for the unit in question.

Reliability in extreme climates: Hot Gas Pipe technology

The AE-X12CU outdoor model is equipped with the patented Hot Gas Pipe system, which reuses residual heat from the heating cycle to prevent the outdoor unit from freezing.

Benefits :

• Fewer prolonged defrost cycles

• No additional external electrical resistance

• Increased stability during ice storms

• Protection against ice buildup

When installing on the North Shore (Terrebonne, Blainville) , we often recommend this type of system to owners exposed to open winds.

Technical installation: details that customers should know

A professional installation is not limited to simply fixing the unit to the wall.

Important technical specifications:

• Voltage: 220V

• MCA: compliant with the dedicated circuit

• MOP: 15A

• Piping: 1/4 – 3/8 in

• Standard length included: up to 25 feet (depending on configuration)

• Indoor noise level: 23 to 43 dB(A)

• Outdoor noise level: 50 dB(A)

The low noise level is particularly appreciated in condominiums in Montreal and Longueuil , where municipal regulations impose strict thresholds.

At AirGreen, each installation includes:

• Wall mount or anti-vibration base

• Clean drilling and external sealing

• Complete vacuum sealing

• Pressure test

• Airflow validation

• WiFi setup included

SHARP AIR mobile app: smart control

WiFi is included as standard. The app allows you to:

• Weekly programming

• Energy consumption monitoring

• Remote adjustment

• Maintenance alerts

For owners of rental plexes in Montreal , this feature facilitates energy management between tenants.

Simplified maintenance: Integrated AFTER CARE

The AFTER CARE function automatically activates the fan after each air conditioning cycle in order to dry the indoor heat exchanger.

Benefits:

• Reduction of internal humidity

• Reduced risk of mold

• Cleaner air

• Less frequent manual maintenance

During our annual HVAC interviews, we observe that units using AFTER CARE exhibit less microbial buildup.

Guarantee and security

• Warranty: 10 years compressor

• 10-year parts warranty

• Labor: 0 years (extension possible at AirGreen)

• Liability insurance: $5,000,000

• RBQ: 5645-9605-01

We also offer additional guarantees tailored to residential and multi-unit property owners.
