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.

A high-performance multi-zone solution for Quebec's climate realities
At AirGreen, we install HVAC systems daily that are adapted to the demanding climatic conditions of Montreal, Laval, Longueuil, North Shore, and South Shore. The DIRECT AIR DA25 3-head heat pump (-25°C) with an outdoor unit of 48,000 BTU fits perfectly into this reality: a reliable multi-zone solution, capable of heating efficiently even during the most rigorous Quebec winters.
This system can power up to 3 distinct zones, while offering impressive flexibility that can extend up to 5 zones maximum, depending on the chosen configuration. This capability is particularly sought after in intergenerational homes, duplexes, or properties with multiple floors.
Real performance in heating and air conditioning
Capacity adapted to modern residential needs
The DIRECT AIR DA25 heat pump offers a cooling capacity of 48,000 BTU and a heating capacity maintained down to -25°C, making it a solid choice for homes in Greater Montreal.
In a recent project in Boucherville (South Shore), we installed this model in an open-plan house with three main zones:
- Main living room (18,000 BTU)
- Master bedroom (12,000 BTU)
- Finished basement (18,000 BTU)
Result: a stable temperature throughout the house, without overloading the system, even during a cold snap reaching -22°C.
Optimized energy efficiency
- SEER2: 23.43
- HSPF2: 18.71
- EER2: 11.25
- COP at -8°C: 11.83
These performances ensure an excellent balance between comfort and energy consumption, which concretely translates into savings on electricity bills.
According to the official brochure, some models in the series can achieve up to 23.5 SEER and 11.5 HSPF, confirming their overall efficiency.
Smart multi-zone technology: flexibility and control
Uniform air distribution thanks to automatic louvers
An often underestimated advantage: the system integrates automatic vertical and horizontal directional louvers. This allows for homogeneous air diffusion in each room, eliminating cold or overheated zones.
In several installations in Laval, we have observed that this system significantly improves comfort in enclosed spaces, especially bedrooms.
Compatibility with several types of indoor units
The DA25 series allows for great installation freedom:
- Wall-mounted units
- Consoles
- 4-way ceiling cassettes
- Ducted units
- Floor/ceiling
This means that we can adapt each project according to the building's architecture, without compromising on aesthetics or performance.
As indicated in the technical documentation, all indoor units are compatible with single and multi-zone configurations.
HVAC Installation: AirGreen's field expertise
Concrete example: triplex in Montreal
We recently installed this system in a triplex in Montreal East. The main challenges were:
- Restricted spaces for ducts
- Need for independent air conditioning per floor
- Minimal noise required
Solution implemented:
- One DIRM-48DA25-5Z outdoor unit
- Three strategically positioned wall-mounted units
- Reinforced acoustic insulation
Result:
- Indoor sound level as low as 22.5 dB(A)
- Uniform thermal comfort
- Installation completed in one day
Advanced features for optimal comfort
Smart options and automation
- Optional WiFi (Google and Alexa compatible)
- "Follow Me" function to adjust temperature based on your location
- Motion and humidity sensor
- Integrated self-cleaning
- Turbo and eco modes
These features allow for precise control and intelligent management of your HVAC system.
Reliability and durability
DIRECT AIR systems are designed to high quality standards, offering increased reliability and a long lifespan.
Multi-zone installation: rules to follow (AirGreen expertise)
A crucial technical point often overlooked:
The total capacity of the indoor units must be within a range of 66% and 133% of the outdoor capacity.
In several cases, we have corrected poorly sized installations carried out by other contractors. A bad combination can lead to:
- Loss of heating performance
- Inefficient operating cycle
- Premature compressor wear
At AirGreen, each project is precisely calculated to avoid these errors.
Grant and profitability
LogisVert Program
This heat pump is eligible for a $1,700 subsidy, which significantly improves the return on investment.

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 3 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.
