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 3 heads.
Can I mix head sizes?
Yes. The “Zones” menu offers 15 combinations, from 12+12+12 to 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.
