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.
Tell us your rooms. We tell you if this size is enough.

A Multi-Zone HVAC Solution Designed for Quebec's Extreme Winters
In the demanding climate of Montreal, Laval, Longueuil, the North Shore, and the South Shore, choosing a heat pump capable of maintaining high heating performance down to -35°C is not a luxury, but a necessity. At AirGreen, we have installed several DIRECT AIR HEAT XTREME PRO systems in residences and multi-unit buildings, and this 2-zone 48,000 BTU model stands out as a reliable, high-performance, and cost-effective solution.
This multi-zone heat pump can power two distinct areas with a single outdoor unit, while maintaining flexibility for up to 5 zones maximum as needs evolve.
Real Heating and Cooling Performance: More Than Just a Spec Sheet
Capacity and Energy Efficiency
The DIRECT AIR HEAT XTREME PRO 48,000 BTU Heat Pump offers:
- Cooling Capacity: 48,000 BTU
- Power at -15°C: 45,000 BTU
- Power at -8°C: 36,000 BTU
- SEER2: 21.830
- HSPF2: 19.815
- EER2: 11.720
- COP at -8°C: 12.03
These figures indicate excellent efficiency for an HVAC installation in Montreal, especially in winter. According to technical documentation, Heat Xtreme Pro systems maintain stable heating operation down to -35°C, with an operational range from -35°C to 30°C for heating and -30°C to 50°C for cooling.
Concrete Example of an AirGreen Installation
In Boucherville (South Shore), we recently installed this model in a multi-generational home. The client wanted:
- Stable temperature in the main dwelling
- Independent control for the basement
Thanks to the 2-zone configuration, we installed:
- An 18,000 BTU wall-mounted unit on the ground floor
- A 12,000 BTU wall-mounted unit in the basement
Result: a 32% reduction in heating bills from the first winter, while maintaining constant comfort, even during cold snaps.
Multi-zone Flexibility: An Evolving and Smart Solution
Configuration and Combination Rules
The DIRECT AIR multi-zone system allows different indoor units (wall-mounted, consoles, ceiling cassettes, etc.) to be connected. An essential rule to follow:
- Total indoor capacity = between 66% and 133% of outdoor capacity
This optimizes overall performance without overloading the compressor.
Compatible Unit Types
- Classic wall-mounted units (most commonly installed in Montreal)
- Wall-mounted consoles for basements
- 4-way ceiling cassettes for open spaces
- Ducted units for more complex projects
At AirGreen, we always recommend a personalized analysis to choose the ideal combination based on the building's surface area and configuration.
Advanced Comfort: More Than Just Heating and Cooling
Smart Air Distribution
This model offers automatic control:
- Vertical vanes: Auto
- Horizontal vanes: Auto
This ensures uniform air distribution, preventing cold or hot spots.
Integrated Technologies
Indoor units include:
- Automatic restart
- Automatic defrost
- 24h timer
- Humidity sensor
- "Follow me" function
- Self-cleaning
- Motion sensor
These features allow for intelligent comfort management, particularly useful in modern homes in Laval and Longueuil.
HVAC Installation: What Our Clients Absolutely Need to Know
AirGreen Standard Installation
When installing this 2-zone heat pump, we typically include:
- Up to 15 feet of refrigerant tubing
- Complete electrical connections
- Wall or ground mount for the outdoor unit
- Full commissioning
Common Mistakes to Avoid
After several hundred HVAC installations, we often observe:
- Undersizing of indoor units
- Incorrect positioning of wall-mounted units
- Ignoring building heat losses
In Montreal, where temperature variations are significant, incorrect configuration can considerably reduce system performance.
Noise Level and Acoustic Comfort
- Indoor: 28 to 41 dB(A) (very quiet)
- Outdoor: 65 dB(A)
During a recent project in Laval, a client was replacing an old noisy heat pump. After installing the DIRECT AIR model:
- Significant reduction in outdoor noise
- Improved indoor comfort, especially at night
Subsidies and Profitability in Quebec
This model is eligible for:
- LogisVert Subsidy: up to $4320
Thanks to its certification:
- ENERGY STAR®
- ENERGY STAR® Cold Climate
- AHRI: 207743794
This makes it an excellent choice for maximizing savings in government programs.

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 2 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.
