Outdoor unit
One compressor for the whole house. It supplies up to 5 heads and modulates from 13,000 to 37,000 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.
Pick the number of rooms and their size. The estimate targets a −15 °C day; it is a guide, the real calculation is done room by room at your home.

A Powerful and Reliable Multi-Zone Solution for Quebec Winters
At AirGreen, we regularly install multi-zone systems in residences and buildings in Montreal, Laval, Longueuil, the North Shore, and the South Shore, and the DIRECT AIR DA25 48,000 BTU 2-head heat pump is among the most requested configurations for properties requiring precise control of two distinct zones. This solution combines power, flexibility, and efficiency, while offering excellent value for demanding owners.
A Heat Pump Designed for Quebec's Climate
Performance Down to -25°C: An Essential Criterion
In the metropolitan region, winter temperatures regularly drop below -20°C. This DIRECT AIR heat pump is designed to maintain stable performance down to -25°C, making it a solution perfectly suited to the Quebec climate.
According to technical data from official documentation, the system offers:
- A heating operating range down to -25°C
- Stable capacity even in extreme conditions
- Reliable air conditioning operation up to 50°C
This concretely means that even during cold snaps in Montreal or Laval, the system continues to ensure constant comfort without relying entirely on auxiliary heating.
2-Zone Configuration: Flexible and Tailored Comfort
Why Choose a Dual-Zone Heat Pump?
A 2-head heat pump allows two independent indoor units to be connected to a single outdoor unit. This is an ideal solution for:
- Duplexes and triplexes
- Houses with an upper floor and basement
- Condos with separate living areas
- Offices or commercial spaces
Each zone can be controlled individually, allowing for:
- Personalized temperature management
- Reduced energy consumption
- Optimal comfort according to actual room occupancy
Concrete Example of an AirGreen Installation
In Boucherville (South Shore), we recently installed this model in a cottage with:
- A 12,000 BTU wall-mounted unit on the ground floor
- An 18,000 BTU wall-mounted unit upstairs
Result:
- 28% reduction in heating costs
- Uniform comfort throughout the house
- No need for an additional system in winter
Detailed Technical Specifications
Outdoor Unit: Power and Stability
- Cooling Capacity: 48,000 BTU
- Heating Capacity: up to -25°C
- Power at -15°C: 33,000 BTU
- Voltage: 220V
- Outdoor Sound Level: 64 dB(A)
- Refrigerant: R-410A
- AHRI: 207743782
Energy Efficiency
- SEER2: 123.43
- HSPF2: 18.715
- EER2: 112.52
- COP at -8°C: 11.83
These values demonstrate highly attractive energy efficiency for a multi-zone system of this capacity, particularly for large homes.
Advanced Technology and Features
Smart and Automated Comfort
Compatible indoor units offer several modern features:
- Automatic Restart
- Automatic Defrost
- 24-hour Programmable Timer
- Energy Saving Mode
- Turbo Mode for Rapid Heating/Cooling
- "Follow Me" Function to Adjust Temperature Based on User Location
Optimized Air Management
- Automatic directional vanes (vertical and horizontal)
- Uniform diffusion throughout the room
- Vane position memory
These elements help avoid cold or hot spots, a common problem in poorly designed systems.
Multi-Zone Installation: Rules and Expertise
Precise Sizing is Essential
A frequently overlooked point: the combination of indoor units must adhere to specific technical rules. As stated in the documentation:
- Total capacity of indoor units:
- Minimum: 66% of the outdoor unit
- Maximum: 133%
An incorrect combination can lead to:
- Loss of performance
- Excessive energy consumption
- Premature wear
AirGreen Expertise
At AirGreen, we systematically analyze:
- Exact surface area
- Building insulation
- Solar exposure
- Occupancy habits
This allows us to avoid common mistakes we observe when replacing poorly installed systems in Montreal and Laval.
Compatible Indoor Unit Types
A major advantage of this DIRECT AIR series is its compatibility with several unit types:
- Wall-mounted (most popular)
- Consoles
- 4-way ceiling cassettes
- Ducted units (concealed)
- Ceiling/floor
This allows for perfect adaptation according to architectural constraints.
Real Example
In Longueuil, we installed:
- A wall-mounted unit in the living room
- A console in the basement
The client wanted to avoid major work: this configuration allowed for quick installation without structural modification.
Sound Level and Acoustic Comfort
- Indoor: as low as 22.5 dB(A)
- Outdoor: approximately 64 dB(A)
In an urban context like Montreal, sound level is a key factor. This heat pump remains discreet, even during continuous operation.
Subsidies and Profitability
LogisVert Subsidy
- Estimated Amount: $1700
This significantly reduces the acquisition cost.

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: 34,000 BTU/h at −8 °C, 33,000 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?
$1,700 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, ID 2473854. It also meets the ENERGY STAR Most Efficient criteria, according to the ENERGY STAR database.
Down to what temperature does it heat?
Down to −25 °C.
Is it noisy?
Indoors, the reference head goes down to 22.5 dB(A). Outdoors, 64 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 5 years on the compressor and 5 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.
