Tailor-made comfort for four distinct zones thanks to FUJITSU Aquila R32 technology
When your cooling and heating needs extend beyond a single room, the solution becomes clear: a reliable, high-performance multi-zone heat pump that's adapted to Quebec's climate. This is exactly what the FUJITSU Aquila R32 | 45,000 BTU QuadZone Heat Pump offers, a highly flexible system designed to serve up to four zones in your home or business in Montreal, Laval, the South Shore and the North Shore .
45,000 BTUs of power for comfort in all weather conditions
Performance is at the heart of this AOUH45KWAS5 outdoor unit, which delivers a cooling capacity of 45,000 BTU and maintains a heating capacity down to -15 °C . It works with an INVERTER compressor , ensuring precise and constant adjustments according to the needs of each room. Thanks to its environmentally friendly R-32 refrigerant , this system not only offers better energy performance, but also reduces its environmental impact.
Why choose a QuadZone heat pump?
Installing a 4-zone heat pump maximizes comfort while avoiding the energy losses often associated with centralized systems. Each wall-mounted heat pump operates independently, providing a customized temperature in each room: living room, bedroom, basement, office, etc.
At AirGreen, we have installed this model in many different configurations throughout Boucherville, Sainte-Thérèse, Verdun and Saint-Lambert . One client in Laval opted for a 7+7+12+18 combination, ideal for his living spaces, master bedroom, and a renovated basement playroom. The result? Total temperature control , room by room, without conflict between family members.

A design thought out for the Quebec climate
Designed to operate from -15°C to +50°C , this heat pump easily withstands the region's harsh winters and humid summers. Its Blue Fin coated heat exchanger provides increased corrosion resistance, essential in urban environments like Montreal or along the river on the South Shore .
Thanks to its low-noise helical fan , the outdoor units can be installed near homes without disturbing the peace and quiet of the neighborhood.
Reliability backed by a solid guarantee
The heat pump is covered by a standard 10-year warranty on the compressor and parts . An extended warranty (10-10-10) is also available for those who wish to include labor. This type of coverage is particularly appreciated by rental property owners on the North Shore .

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: 31,000 BTU/h at −8 °C, 36,000 at −15 °C.
How many heads can I connect?
Up to 5 on this outdoor unit. This product is configured for 4 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 68 combinations, from 7+7+7+7 to 9+18+18+18 (in thousands of BTU). Each head is sized for its room.
How much is the LogisVert grant?
$3,720 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 3630083. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −15 °C.
Is it noisy?
Indoors, the reference head goes down to 19 dB(A). Outdoors, 56 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 12 years on the compressor and 12 years on parts; labour is not included by the manufacturer. 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.
