Outdoor unit
One compressor for the whole house. It supplies up to 4 heads and modulates from 10,000 to 35,200 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 Multi-Zone HVAC Solution Designed to Withstand Quebec's Extreme Winters
In Quebec's climate, choosing a heat pump capable of maintaining stable performance at very low temperatures is not a luxury, but a necessity. At AirGreen, we regularly install multi-zone systems in Montreal, Laval, Longueuil, the North Shore, and the South Shore, and the DIRECT AIR HEAT XTREME PRO 4-Zone Heat Pump (-35°C) clearly stands out in this category.
This 36,000 BTU model was designed to power up to 4 independent zones, allowing for precise comfort management in each room. This flexibility is particularly sought after in multi-story homes, plexes, or renovation projects where a centralized solution is difficult to implement.
Reliable Performance Down to -35°C: An Essential Criterion in Quebec
Extreme Heating Without Compromise
One of the most critical points when choosing a heat pump is its actual ability to heat effectively in winter. This model stands out for:
- Guaranteed operation down to -35°C
- Heating capacity maintained even at -15°C and -8°C
- Inverter technology for dynamic power adjustment
According to the official brochure, the HX PRO series heat pumps offer an operating range from -35°C to 30°C for heating, which largely covers the conditions encountered in the greater Montreal area.
AirGreen Case Study
We recently installed this model in a duplex in Longueuil. The client previously used expensive electric baseboards. After installation:
- Estimated consumption reduction: 35 to 45%
- Uniform comfort on 3 floors
- No reliance on auxiliary heating down to -25°C
Intelligent Comfort Management with 4 Independent Zones
Why Multi-Zone Changes Everything
A quad-zone heat pump allows you to connect up to 4 different indoor units (wall-mounted, consoles, ceiling cassettes, etc.), each controlled independently.
Concrete Advantages:
- Heating only used rooms
- Reduced energy costs
- Personalized comfort for each occupant
Essential Installation Rule
As indicated in the technical documentation, the total capacity of the indoor units must comply with a specific range:
- Minimum: 66% of outdoor capacity
- Maximum: 133% of outdoor capacity
At AirGreen, we systematically validate these parameters to avoid performance losses, particularly in heating mode.
Complete Technical Specifications
Here are the key features of this model:
- Cooling Capacity: 36,000 BTU
- Heating Capacity: up to -35°C
- AHRI: 207743791
- ENERGY STAR®: Yes (Cold Climate)
- SEER2: 22.3
- HSPF2: 10.3
- EER2: 13.6
- COP at -8°C: 1.93
- Refrigerant: R-410A
- Outdoor Sound Level: 63 dB(A)
- Voltage: 220V
These performances ensure excellent energy efficiency, essential for maximizing available subsidies in Quebec.
Subsidies and Real Savings
LogisVert Subsidy
This model is eligible for a provincial subsidy of up to:
- $3,960 (updated November 2025)
This significantly reduces the initial cost and accelerates the return on investment.
Concrete Example
In a project carried out in Laval:
- Total cost after subsidy: reduced by almost 30%
- Estimated return on investment: 3 to 5 years
- Immediate improvement in thermal comfort
Designed for Durability and Comfort

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: 33,000 BTU/h at −8 °C, 36,000 at −15 °C.
How many heads can I connect?
Up to 4 on this outdoor unit. This product is configured for 4 heads.
How much is the LogisVert grant?
$3,960 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 3996075. 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, 63 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.
