Outdoor unit
One compressor for the whole house. It supplies up to 2 heads and modulates from 5,700 to 19,000 BTU/h depending on what the rooms call for (NEEP).
Base pan heater
A heater keeps the outdoor unit’s base pan free of ice below 1 °C and during defrost (NEEP).
Refrigerant lines
One pair of lines per head.
Indoor heads
One head per room, each with its own remote and temperature. The combination is chosen in the “Zones” menu.
Control
Each zone is set separately.
Turn rooms on and off. Watch the power being shared.
One outdoor unit supplies every head: when several rooms call at once, they share its capacity. Pick an outdoor temperature.

A Multizone HVAC Solution Designed for Quebec's Demanding Climate
At AirGreen, we daily install HVAC systems tailored to the climatic realities of Montreal, Laval, Longueuil, the North Shore, and the South Shore. The DIRECT AIR HEAT XTREME PRO (-35°C) 2-zone heat pump stands out as a reliable solution for properties requiring precise control of two distinct spaces, while maintaining stable performance even during harsh winters.
This model, featuring an 18,000 BTU outdoor unit, allows for the connection of two wall-mounted indoor units (6,000, 9,000, or 12,000 BTU), offering true flexibility for multi-story homes, condos, or duplexes.
Extreme Performance Down to -35°C: An Essential Criterion in Quebec
Advanced Heating Capacity for the Canadian Winter
The main strength of this heat pump lies in its ability to maintain efficient performance down to -35°C, a critical threshold for installations in Montérégie, Laval, or on the North Shore.
Unlike many standard models that rapidly lose efficiency below -15°C, this system:
- Still provides 15,000 BTU at -8°C
- Can reach up to 19,700 BTU at -15°C
- Maintains thermal stability even during long cold spells
According to the manufacturer's technical specifications, the Heat Xtreme Pro series is specifically designed to operate within a range of -35°C to 30°C for heating, making it a perfectly suited option for the Quebec climate.
Energy Efficiency and Certifications
This model is certified:
- ENERGY STAR®
- ENERGY STAR® Cold Climate
- AHRI: 207743785
With solid performance:
- SEER2: 22+ (up to 25 depending on the series)
- HSPF2: 19.815
- COP at -8°C: 1.93
This means real savings on energy bills, especially for homeowners replacing traditional electric heating.
2-Zone Configuration: Flexibility and Personalized Comfort
Smart Heat and Air Conditioning Distribution
A 2-zone heat pump allows independent control of two distinct spaces:
- Master bedroom + living room
- Ground floor + upstairs
- Office + living area
Each indoor unit can be adjusted according to specific needs, avoiding energy losses associated with uniform heating.
Combination Rules and Optimization
The system adheres to precise capacity rules to ensure optimal performance:
- Total indoor capacity between 66% and 133% of outdoor capacity
- Common example installed by AirGreen:
- 1 x 12,000 BTU + 1 x 9,000 BTU on an 18,000 BTU unit
In our installations in Longueuil and Boucherville, this configuration is frequently used to maximize comfort without oversizing the system.

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: 15,000 BTU/h at −8 °C, 19,700 at −15 °C.
How many heads can I connect?
Up to 2 on this outdoor unit. This product is configured for 2 heads.
How much is the LogisVert grant?
$1,800 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 2473908. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −35 °C.
Is it noisy?
Indoors, the reference head goes down to 28 dB(A). Outdoors, 61 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; 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.
