Outdoor unit
One compressor for the whole house. It supplies up to 5 heads and modulates from 13,000 to 45,000 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 High-Performance Multi-Zone HVAC Solution for Quebec's Harsh Winters
At AirGreen, we regularly install high-performance multi-zone systems to meet the specific needs of residences and multiplexes in Montreal, Laval, Longueuil, the North Shore, and the South Shore. The DIRECT AIR HEAT XTREME PRO 48,000 BTU 3-zone heat pump clearly stands out for its ability to maintain reliable heating down to -35°C, while also offering stable air conditioning in the summer.
This model represents a strategic solution for homeowners looking to optimize their comfort in multiple rooms without installing several independent systems.
A Heat Pump Designed for Extreme Climatic Conditions
Heating Performance down to -35°C
In the Quebec context, low-temperature heating capacity is a decisive factor. This DIRECT AIR HEAT XTREME PRO model is specifically designed to operate efficiently down to -35°C, making it an ideal option for winters in Montreal and Montérégie.
According to technical documentation, these systems maintain stable heating capacity even at -15°C and -8°C, ensuring constant comfort in the serviced areas.
Certified Energy Efficiency
- ENERGY STAR® (Cold Climate): Yes
- SEER2: 21.5 (up to 25 depending on the series)
- HSPF2: up to 12
- COP at -8°C: 12.03
These values demonstrate high energy efficiency, which is essential for reducing electricity costs, especially with Hydro-Québec's rates.
Multi-Zone Configuration: Maximum Flexibility for Your Home
3-Zone System (expandable up to 5)
This model is designed to power 3 distinct zones, with a maximum capacity of up to 5 indoor units. This allows for:
- Heating and cooling multiple rooms independently
- Adjusting the temperature according to the use of each space
- Reducing overall energy consumption
Compatible Indoor Unit Types
The HEAT XTREME PRO series offers great flexibility:
- Wall-mounted units (most common)
- Consoles

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: 36,000 BTU/h at −8 °C, 45,000 at −15 °C.
How many heads can I connect?
Up to 5 on this outdoor unit. This product is configured for 3 heads.
How much is the LogisVert grant?
$4,320 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 2473685. 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, 65 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.
