Outdoor unit
One compressor for the whole house. It supplies up to 3 heads and modulates from 8,400 to 22,600 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 powerful and practical multi-zone solution for homes in Greater Montreal
At AirGreen, we regularly install multi-zone systems in houses, condos, and duplexes in Montreal, Laval, Longueuil, North Shore, and South Shore. The DIRECT AIR DA25 (-25°C) | 27,000 BTU 2-head heat pump stands out as a balanced solution for clients who want to efficiently air condition and heat two distinct zones with a single outdoor compressor.
This model directly addresses a common real-world scenario: a house with an open ground floor and a closed upper floor, or a condo with a main living area + bedroom. In these situations, a single wall-mounted unit is insufficient, and a central installation is often too invasive or costly. This is precisely where this system excels.
A Heat Pump Designed for Quebec Winters
Performance down to -25°C: an essential criterion
The heating capacity down to -25°C is a crucial factor for our market. In the field, we've observed that several less efficient systems become ineffective at -15°C, forcing clients to compensate with electric baseboard heaters.
With this DIRECT AIR DA25 model:
- Heating maintained down to -25°C
- Heating capacity of 21,000 BTU at -8°C
- Approximately 19,000 BTU at -15°C
This significantly reduces electricity costs in winter, especially in exposed areas like the North Shore or certain open areas of the South Shore.
According to technical documentation, Direct Air systems are designed to operate within a full range of -25°C to 30°C for heating, which perfectly matches Quebec's climatic conditions.
Dual Zone Configuration: Flexibility and Real Comfort
2 independent zones, up to 3 zones possible
This model is a multi-zone heat pump with:
- 2 indoor units (standard)
- Possibility of up to 3 zones
- Outdoor unit: DIRM-27DA25-3Z
This allows for:
- Independent control of each room
- Different temperatures based on usage
- Reduction of energy waste
Real-world AirGreen installation example
In Boucherville, we installed this system in a cottage:
- 1 x 12,000 BTU unit on the ground floor
- 1 x 9,000 BTU unit upstairs
Result:
- Stable temperature throughout the house
- Elimination of cold zones upstairs
- Over 30% reduction in winter energy bill
Energy Efficiency and Technical Performance
Key Indicators
- SEER2: 24.6 (efficient air conditioning)
- HSPF2: 9.5+ (high-performance heating)
- EER2: 11.27
- COP at -8°C: 2.03
These values indicate good overall efficiency, particularly in heating mode.
According to the brochure, some models in the series reach up to 23.5 SEER and 11.5 HSPF, positioning this range among high-performance residential solutions.

HVAC Installation: What You Really Need to Know
Technical Requirements

Common Error Observed
We often see poorly sized installations:

At AirGreen, we systematically validate these calculations before installation.
Subsidies and Profitability

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: 21,000 BTU/h at −8 °C, 19,000 at −15 °C.
How many heads can I connect?
Up to 3 on this outdoor unit. This product is configured for 2 heads.
How much is the LogisVert grant?
$1,050 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 2473843. 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, 61 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.
