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

A wall-mounted heat pump designed for Quebec winters and demanding summers

The SHARP CHU Wall Mounted Heat Pump | 12,000 BTU | R32 -30°C is aimed directly at residential owners in Montreal, Laval, Longueuil, North Shore and South Shore who are looking for a reliable, high-performance and energy-efficient solution to face extreme weather conditions.

At AirGreen , we've been installing HVAC systems in single-family homes, condos, duplexes, and multi-unit dwellings for years. This 12,000 BTU SHARP CHU model is one of the units we frequently recommend when:

• The area to be air-conditioned is around 500 to 900 sq ft (depending on the insulation).

• The customer wants an ENERGY STAR® Cold Climate certified appliance.

• Winter comfort down to -30°C is a real priority, not a theoretical one.

• The goal is to maximize LogisVert subsidies while maintaining modern R-32 technology.

Key technical specifications

Here are the most important technical elements we analyze during our submissions:

• Cooling capacity : 12,000 BTU

• Power at -8°C : 18,900 BTU

• Power at -15°C : 16,000 BTU

• Heating capacity down to -30°C

• Refrigerant : R-32 (more environmentally friendly than R-410A)

• SEER2 : 25.0

• HSPF2 : 11.0

• EER2 : 16.0

• COP at -8°C : 2.13

• Indoor noise level : as low as 22 dB(A)

• Voltage : 220V

• Piping : 1/4 – 3/8

• Warranty : 10 years compressor, 10 years parts

These figures are not simply marketing ploys. On the ground, we are seeing the concrete impact of these performance levels on electricity bills.

Cold climate performance: much more than just a "-30°C" rating

Many heat pumps boast a high nominal capacity but quickly lose efficiency when the temperature drops below -15°C. This SHARP CHU model is Cold Climate certified, meaning it has been designed to operate reliably in harsh winter conditions.

Cold resistance technology

The outdoor unit is equipped with an advanced defrosting system using Hot Gas Pipe technology, which recycles heat to prevent excessive freezing. In the Montreal and Laval area, where winter humidity is high, this detail makes a significant difference.

During a recent installation in Boucherville (South Shore) , a client was replacing an older heat pump that was constantly going into extended defrost mode. After installing the SHARP CHU model:

• The defrosting cycle has become shorter and more stable.

• The indoor temperature remained constant.

• Electricity consumption in January decreased by approximately 18% compared to the previous year.

Air diffusion comfort: Coanda and Multi Space technology

Comfort depends not only on BTU output, but also on how the air is distributed.

Coanda Airflow Technology (up to 50 feet)

The air distribution can reach up to 50 feet, which is especially useful in the open-concept condos common in Longueuil and on the North Shore . In cooling mode, the air is directed upwards along the ceiling before gently descending. In heating mode, the airflow descends towards the floor.

Result :

• Less sensation of a direct draft.

• More uniform temperature.

• Better thermal stratification in winter.

Multi-Space Function

This function allows air to be distributed to adjacent rooms such as a hallway or an open-plan dining room. Of course, this depends on the layout of the dwelling, but in several projects in Ahuntsic and Rosemont , we were able to avoid adding a second unit thanks to this air projection capability.

Air quality and simplified maintenance

AFTER CARE function

The AFTER CARE function automatically dries the indoor unit after the cooling mode is switched off. This reduces residual moisture, limiting the formation of internal mold.

For homeowners who neglect HVAC maintenance , this feature offers a real advantage. It doesn't replace annual professional servicing, but it helps prolong indoor cleanliness.

Easy cleaning

The filter is easily accessible without complex disassembly. During our service calls in Laval or on the South Shore , we often see units where access to the filters is complicated, which discourages owners.

Here, access is direct, and basic maintenance can be carried out in a few minutes.

Smart control and mobile app

The SHARP CHU 12,000 BTU includes built-in WiFi and works with the SHARP AIR mobile app.

Main features:

• Schedule.

• Remote temperature adjustment.

• Energy consumption monitoring.

• Filter cleaning alerts.

In several downtown Montreal locations, customers use this feature to preheat their condos before arriving home from work. This improves comfort without maintaining a high temperature all day.

Motion Sensor

This model includes a smart presence sensor:

• Automatic power reduction when the room is empty.

• Returns to normal mode as soon as movement is detected.

In a duplex in Laval , this system allowed an owner-occupier to optimize consumption in his home office, which was often unoccupied during certain hours.

LogisVert subsidy and eligibility

The LogisVert Provincial Grant can reach $2268 (updated November 2025).

At AirGreen, we:

• Let's verify full eligibility.

• Let's fill out the technical documentation.

• Let's use the official AHRI numbers (217512736).

• Let's validate the electrical requirements (MOP 20A).

Many errors in applications stem from non-compliant facilities or incorrect AHRI numbers. We have already reviewed cases where the grant was denied due to incorrect reporting.

Professional installation: what we do differently

A high-performance heat pump that is poorly installed quickly loses efficiency.

During our HVAC installations in Montreal and the Montérégie region , we:

1. Let's check the available electrical capacity.

2. Let's install a wall or slab mount suitable for winter conditions.

3. Let's use a complete vacuum to remove moisture from the circuit.

4. Let's calibrate the pressure according to R-32 specifications.

5. Let's test the heating and air conditioning performance.

We have corrected several installations done by other contractors where:

• The length of piping exceeded the recommendations.

• The drain was incorrectly angled.

• The circuit breaker was not suitable.

These details directly influence the lifespan of the compressor.

Dimensions and aesthetic integration

Indoor unit:
41.42 x 9.80 x 12.44 inches

Outdoor unit:
30.72 x 10.59 x 21.25 inches

Available in white and black depending on certain configurations.

In modern renovations in Plateau Mont-Royal , several clients choose the black version for a more discreet integration into contemporary decors.
