SHARP CU Wall-Mounted Heat Pump | 24,000 BTU | R32 -30°C

A 24,000 BTU wall-mounted heat pump designed for Quebec's harsh winters

In Greater Montreal, choosing a 24,000 BTU wall-mounted heat pump isn't just about comparing numbers on a spec sheet. You have to consider the local climate: cold winds on the North Shore , high humidity in Longueuil , large open spaces in Laval , and the typical duplexes and triplexes of Montreal .

At AirGreen, we install the SHARP CU Wall-Mounted Heat Pump | 24,000 BTU | R32 -30°C in a wide variety of settings: modern open-concept condos, 1970s single-family homes, local businesses, and multi-unit dwellings. This model is part of Sharp's CU series, designed to deliver stable heating performance down to -30°C while maintaining excellent energy efficiency.

Unlike the CHU series, the CU series does not include a motion sensor or automatic left-right horizontal oscillation . This allows investment to be focused on thermal performance, mechanical reliability, and build quality, rather than on advanced features that are not essential for all users.

Actual performance: heating down to -30°C and certified efficiency

Capacity and yield in cold climates

This SHARP 24,000 BTU wall-mounted heat pump is distinguished by:

• Cooling capacity: 24,000 BTU

• Power at -8°C: 22,400 BTU

• Power at -15°C: 19,000 BTU

• Reliable operation down to -30°C

• R-32 refrigerant, more environmentally friendly and more efficient than R-410A

• ENERGY STAR® and ENERGY STAR® Cold Climate certification

• AHRI: 217508895

• SEER2: 21.0

• HSPF2: 9.5

• EER2: 12.5

• COP at -8 °C: 12.23

In several installations completed by our team in Boucherville (South Shore) and Blainville (North Shore) , we measured very stable performance even during cold spells below -20°C. The system maintained the indoor temperature without excessive reliance on supplemental heating.

Hot Gas Pipe Technology: Frost protection

One element often overlooked by homeowners is defrost management. The CU series incorporates a Hot Gas Pipe system that reuses the generated heat to prevent the outdoor unit from freezing.

In a project in Ahuntsic (Montreal) , an older heat pump from another brand was entering defrost cycles too frequently, causing temperature fluctuations. After replacing it with the SHARP CU 24,000 BTU, thermal stability improved significantly.

Indoor comfort: optimized air distribution without unnecessary complexity

Coanda Airflow Technology (up to 50 feet)

Coanda Airflow technology allows air to be projected up to 50 feet.

• In air conditioning: the air is directed towards the ceiling.

• In heating mode: the air is directed downwards for better stratification.

In an open-concept 1,100 sq ft condo in Laval , this feature effectively covered the living room and adjacent kitchen without creating a direct draft on the occupants.

Multi-Space Function

The Multi Space function helps to distribute air to connected spaces, such as a hallway or an adjacent dining room.

This is particularly useful in Montreal plexes where the main area opens onto several rooms.

Shutter control

• Vertical shutter: automatic

• Horizontal panel: manual

We always explain this nuance to our customers: the CU series offers reliable control, but without automatic motorized horizontal adjustment. For many homeowners, this isn't a problem, as the initial orientation is set during installation.

Simplified maintenance and durability

AFTER CARE function

After each air conditioning cycle, the AFTER CARE function activates the fan to dry the inside of the unit.

This reduces:

• The accumulation of moisture

• The development of mold

• The smells

In our HVAC maintenance contracts in Montreal and Longueuil , we observe that units equipped with this function show less biofilm accumulation on the evaporator.

Easy cleaning

The filter is easily accessible and can be cleaned without complex disassembly. For busy families on the South Shore , this simplicity is a real advantage.

Smart control with built-in WiFi

The SHARP CU 24,000 BTU heat pump includes built-in WiFi via the SHARP AIR app:

• Remote adjustment

• Timetable

• Consumption tracking

• Cleaning alerts

A homeowner in Vimont (Laval) uses programming to reduce the temperature during the day and raise it again before returning home, thus optimizing consumption.

Key technical specifications for installation

Dimensions

• Interior dimensions: 41.42 x 9.80 x 12.44 in

• Exterior dimensions: 33.47 x 13 x 27.94 in

Piping

• 1/4 – 3/8 in

Noise level

• Indoor: 25 to 49 dB(A)

• Outdoor: 54 dB(A)

Electric

• 220V

• MOP: 25A

During every HVAC installation in Montreal or on the North Shore , we check:

1. Electrical panel capacity

2. Actual pipe length

3. Adequate drainage

4. Wall mount or anti-vibration base

LogisVert subsidy and profitability

This heat pump is eligible for the LogisVert Provincial Grant: $2,688 (updated November 2025).

We support our clients in:

• Eligibility check

• AHRI Number

• Complete documentation

• Conforming submission

In several projects in Longueuil and Brossard , the subsidy significantly reduced the net cost, making the investment very competitive compared to a traditional electrical system.

Guarantee and peace of mind

• 10-year compressor warranty

• 10-year parts warranty

• Labor: 0 years (extension possible)

At AirGreen, we offer extended warranties and a structured after-sales service with:

• $5M liability insurance

• Certified refrigeration technicians

• Post-installation follow-up

AirGreen Experience: Beyond Installation

We installed this model in:

• A single-family home in Terrebonne

• A condo in Griffintown

• A business in Boucherville

In each case, our approach includes:

• Accurate thermal load calculation

• Clear explanation of capabilities at -15°C and -20°C

• Custom adjustment of settings

A common mistake we often correct is installing an 18,000 BTU unit in a space that actually requires a 24,000 BTU unit. Undersizing a system in a Quebec climate results in reduced heating performance.

Why choose the SHARP CU 24,000 BTU Wall Mounted Heat Pump?

• Excellent performance in cold climates

• R-32 refrigerant is more environmentally friendly

• Built-in WiFi

• Robust design

• Cold Climate Certification

• LogisVert subsidy available

• Professional installation by AirGreen

If you are looking for a wall-mounted heat pump in Montreal, Laval, Longueuil, North Shore or South Shore capable of providing heating and air conditioning all year round, this model represents a balanced choice between performance and reliability.
