A multi-zone heat pump designed for Quebec's harsh winters
At AirGreen, we install HVAC systems adapted to the climatic conditions of Montreal, Laval, Longueuil, the North Shore, and the South Shore . The SHARP CU TripleZone Heat Pump | R32 -30°C is one of the models we regularly recommend for single-family homes, condos, and multi-unit dwellings seeking a high-performance, stable, and energy-efficient multi-zone solution.
The AE-X3M24CU outdoor unit (24,000 BTU) is designed to power up to three compatible indoor units (9,000, 12,000, or 18,000 BTU), allowing independent management of multiple rooms with a single outdoor compressor. This configuration is particularly advantageous for homes with a living room, bedrooms, and office that require separate air conditioning.
Heating performance down to -30°C
The advertised heating capacity down to -30°C meets the demands of Quebec winters. In our facilities on the South Shore and in Laval , we have observed excellent temperature stability even during prolonged cold spells.
Some key technical data:
-
Cooling capacity: 24,000 BTU
-
Power at -8°C: 25,000 BTU
-
Power at -15°C: 21,200 BTU
-
SEER2: 24.0
-
HSPF2: 11.5
-
EER2: 14.0
-
COP at -8°C: 12.33
-
Refrigerant: R-32
-
Voltage: 220V
-
MOP: 25A
-
Outdoor noise level: 54 dB(A)
This model is ENERGY STAR® and ENERGY STAR® Cold Climate certified, making it eligible for the LogisVert grant ($3,000) according to the applicable criteria.
In several projects in Montreal (Rosemont, Ahuntsic) , we replaced old R-410A systems with this R-32 heat pump, which is more efficient and has a lower environmental impact.
Advanced technology and controlled comfort
Sharp's CHU/CU series features air technologies designed for consistent comfort. It's important to note that the CU series does not include the motion sensor or automatic left-right oscillation , features reserved for the CHU series.
Coanda Airflow: long-range air diffusion
Coanda Airflow technology allows for air projection up to 50 feet in certain configurations. The air is directed towards the ceiling in cooling mode and towards the floor in heating mode, avoiding direct drafts.
In a project in Boucherville , a client with an open-plan kitchen and living room wanted to avoid direct airflow onto the dining table. Thanks to the strategic positioning of the wall unit and the management of the automatic vertical louvers, we achieved a gentle and even distribution of air.
Multi-Space Function
The Multi Space function allows you to extend air conditioning to adjacent rooms. In a home in Laval-des-Rapides , we installed a 9,000 + 9,000 + 12,000 BTU configuration connected to a 24,000 BTU AE-X3M24CU compressor. The main living room received 12,000 BTU, while two bedrooms each had independent control.
Result :
-
Improved thermal stability
-
Reduction of short cycles
-
Less electricity consumption compared to three independent systems
Simplified maintenance and increased reliability
One of the features appreciated by our HVAC maintenance technicians in Montreal and Longueuil is the ease of access to the filters and the After Care system.
After Care: Automatic internal drying
After the air conditioning system shuts down, the interior fan continues running briefly to dry the heat exchanger. This limits internal humidity and reduces the risk of mold growth.
In our HVAC maintenance contracts on the North Shore , we find that units using this function correctly exhibit less long-term biological accumulation.
SHARP AIR mobile application
WiFi is included. Users can:
-
Schedule times
-
Adjust the temperature remotely
-
Receive maintenance alerts
-
Monitor energy consumption
For owners of plexes in Montreal , this feature allows for efficient management of rental units without constant travel.
Defrosting technology and cold climate
The CU series uses a Hot Gas Pipe defrosting system, which reuses residual heat from the cycle to prevent the outdoor unit from freezing. Unlike systems using an additional electric heating element, this method improves energy efficiency.
During a particularly cold winter in Blainville , a similar installation maintained stable performance while several competing systems frequently entered prolonged defrost cycles.
Flexible multi-zone configuration
The AE-X3M24CU compressor allows for various combinations:
-
9,000 + 9,000 + 12,000 BTU
-
12,000 + 12,000
-
9,000 + 18,000
This flexibility is ideal for:
-
Intergenerational housing
-
Open-concept condos
-
Duplex and triplex
Each compatible indoor unit (AY-XPC9CU, AY-XPC12CU, AY-XPC18CU, AY-XPC18CU-B) offers quiet operation that can go down to 23 dB(A) depending on the model.
Warranty and protection
The heat pump is covered by:
-
10-year compressor warranty
-
10-year parts warranty
-
6-year labor warranty (straight from the distributor)
-
Additional warranty available through AirGreen
As a company with $5,000,000 liability insurance and RBQ license #5645-9605-01 , we ensure an installation that complies with Quebec standards.
Why choose AirGreen for the installation of your SHARP heat pump?
In the Montreal, Laval, Longueuil, North Shore and South Shore region, the installation of a multi-zone heat pump requires:
-
Precise calculation of thermal loads
-
Electrical panel check (MCA/MOP)
-
Proper sizing of refrigeration lines
-
Compliance with winter outdoor clearance requirements
We have corrected several installations carried out by non-specialized contractors where:
-

What people ask us about multi-zone systems.
Can I heat one room and cool another at the same time?
No. On a multi-zone system like this one, every head works in the same mode, heating or cooling. Each room still keeps its own set temperature.
What happens when every room calls for heat?
They share the outdoor unit’s capacity: 25,000 BTU/h at −8 °C, 21,200 at −15 °C.
How many heads can I connect?
Up to 3 on this outdoor unit. This product is configured for 3 heads.
How much is the LogisVert grant?
$3,000 according to Hydro-Québec’s list of October 1, 2026. The grant never exceeds 100 % of the cost before taxes; apply within 9 months of installation.
Is it ENERGY STAR certified?
Yes, cold climate, ID 4439340. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −30 °C.
Is it noisy?
Indoors, the reference head goes down to 23 dB(A). Outdoors, 54 dB(A): we place the unit away from bedroom windows.
Why a multi-zone instead of several wall units?
One outdoor unit on the wall and one circuit. In return, the rooms share the capacity, and if the outdoor unit stops, every zone stops.
What does the warranty cover?
Our sheet lists 10 years on the compressor and 10 years on parts. AirGreen extended warranty: possible.
A multi-zone system is planned room by room. At your home.
We measure every room, draw the line route and choose the right head for each zone. The on-site estimate is free and the quote arrives within 24 h.
