SHARP CHU-B Black Wall-Mounted Heat Pump | 12,000 BTU | R32 -30°C

A high-end wall-mounted heat pump designed for Quebec's harsh winters

At AirGreen, we install hundreds of wall-mounted heat pump systems every year in Montreal, Laval, Longueuil, as well as on the North and South Shores. Among the models that are particularly popular for single-family homes, condos, and multi-unit dwellings, the SHARP CHU-B Black 12,000 BTU Wall-Mounted Heat Pump stands out for its combination of energy efficiency, cold-climate performance, and distinctive design.

This model, equipped with R-32 refrigerant, is ENERGY STAR® Cold Climate certified and offers heating capacity down to -30°C , an essential criterion for Quebec's climate. It's not simply an air conditioner with a heating option: it's a complete HVAC system designed to operate 12 months a year.

Actual heating performance at -30°C: a decisive criterion in Quebec

Heating capacity adapted to the winters of Montreal and Laval

The SHARP CHU-B 12,000 BTU displays:

• Rated power: 12,000 BTU

• Power at -8°C: 18,900 BTU

• Power at -15°C: 16,000 BTU

• Operating capacity down to -30°C

In practical terms, this means that at -15°C , a common temperature in Montreal and on the South Shore in January, the unit maintains a power output well above its nominal capacity. For our customers in Laval and the Montérégie region who want to reduce their use of baseboard heaters, this performance makes a real difference to their Hydro-Québec bill.

We recently installed this model in a condo in Boucherville (South Shore), approximately 950 sq ft, with an open-concept living room and kitchen. The old system struggled below -20°C. With the SHARP CHU-B, the client experienced significantly improved thermal stability, even during the February cold snaps.

Advanced air diffusion technology: uniform and targeted comfort

Coanda Airflow Technology – Range up to 50 feet

The CHU/CU series incorporates Coanda Airflow technology, capable of projecting air up to 50 feet . In cooling mode, the air is directed towards the ceiling for gentle and even distribution. In heating mode, it is directed towards the floor to counteract the stratification effect.

In open-concept apartments in Montreal or townhouses in Longueuil, this feature is particularly appreciated:

• Fewer cold zones

• More stable temperature

• A feeling of comfort without direct drafts

Multi-Space Function

The Multi Space function allows you to extend comfort to adjacent rooms (hallway, dining room, office space). This sometimes reduces the need to install a second indoor unit, thus lowering HVAC installation costs.

Spot Air (depending on configuration)

For some customers who wish to direct the air towards a specific area (home office corner, living room area), the Spot Air function allows for more targeted control.

Energy efficiency and LogisVert subsidies

High energy efficiency

• SEER2: 25.0

• HSPF2: 11.0

• EER2: 16.0

• COP at -8°C: 12.13

These indicators confirm excellent performance in air conditioning and seasonal heating. For owners of multi-unit dwellings in Montreal looking to optimize the overall energy efficiency of their building, these figures are crucial.

LogisVert Subsidy

As of the update date (November 26, 2025), the LogisVert provincial subsidy associated with this model can reach $2,268 .

At AirGreen, we systematically support our clients in validating eligibility and preparing the required documents (AHRI number 217512733, ENERGY STAR Cold Climate compliance).

R-32 refrigerant: performance and reduced environmental impact

R-32 gas offers:

• Better energy efficiency

• A lower global warming potential (GWP) than R-410A

• A more efficient refrigerant charge

For our clients concerned about reducing their environmental footprint, particularly in residential areas of the North Shore such as Blainville or Terrebonne, this factor is becoming increasingly important.

Intelligent design and simplified maintenance

Simplified cleaning and AFTER CARE function

The indoor unit is designed for easy maintenance:

• Quickly accessible filter

• Easy cleaning

• AFTER CARE function: automatic drying of the indoor unit after use in air conditioning mode, reducing humidity and the risk of mold.

During our HVAC maintenance visits in Montreal, we observe that systems equipped with this function exhibit less odor accumulation and internal deposits.

SHARP AIR Mobile App: Complete remote control

Integrated WiFi connectivity allows:

• Remote adjustment

• Timetable

• Energy consumption monitoring

• Maintenance alerts

For a homeowner in Laval who leaves their home for the weekend, it becomes possible to lower the temperature and then raise it again before returning. This contributes to more precise energy management.
