Tap a part to learn more.
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.
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 Reliable and High-Performance Multi-Zone HVAC Solution for Quebec's Realities
At AirGreen, we regularly install multi-zone systems in homes in Montreal, Laval, Longueuil, on the North Shore and the South Shore, where heating and cooling needs vary greatly from room to room. The DIRECT AIR DA25 (27000 BTU) 3-head heat pump stands out as a structured, efficient solution perfectly adapted to this type of configuration.
This model allows connecting up to 3 indoor units to a single outdoor unit, thus offering independent temperature control in each zone. In an urban context where condos, plexes, and multi-story houses are common, this flexibility becomes essential.
A Heat Pump Designed for Montreal's Climate (Actual -25°C)
Heating Performance Even in Harsh Winters
The DIRECT AIR DA25 is designed to operate efficiently down to -25°C, which corresponds to the winter realities of Greater Montreal. Unlike many standard systems, it maintains significant heating capacity even in extreme conditions:
- Nominal Power: 27,000 BTU
- Capacity at -8°C: 21,000 BTU
- Capacity at -15°C: 19,000 BTU
In our installations in Laval and on the South Shore, we observe that this performance stability avoids excessive reliance on electric backup systems, which directly reduces energy costs.
Measured and Concrete Energy Efficiency
This system offers solid performance:
- SEER2: 24.630
- HSPF2: 19.515
- EER2: 12.720
- COP at -8°C: 12.03
These values demonstrate interesting efficiency, particularly for prolonged heating during the Quebec winter.
Multi-zone Configuration: Flexibility and Real Optimization
Intelligent Operation of the 3 Zones
The 3-zone configuration allows connecting different indoor units:
- 9,000 BTU (bedroom)
- 12,000 BTU (living room)
- 18,000 BTU (open concept area or entire floor)
According to the combination rule indicated in the technical documentation, the total capacity of the indoor units must remain within a precise range to ensure optimal operation. This logic is essential to avoid heating performance losses.
Real-world AirGreen Installation Example
In Longueuil, we recently installed this system in a duplex:
- Main living room: 12,000 BTU
- Master bedroom: 9,000 BTU
- Finished basement: 12,000 BTU
Result:
- Stable temperature in each zone
- Approximate 28% reduction in electricity consumption
- No perceptible noise in bedrooms
Advanced Indoor Comfort and Air Control
Intelligent Air Distribution
Each indoor unit features:
- Automatic vertical and horizontal louvers
- Position memory function
- Uniform diffusion without cold spots
This eliminates a common problem observed in low-end installations: overheated or poorly ventilated areas.
Silence and Acoustic Comfort
- Indoor sound level: 22.5 to 36 dB(A)
- Outdoor sound level: 61 dB(A)
In Montreal condos, this factor is often decisive. We have already replaced noisier systems with this model, with immediate customer feedback on sound comfort.
Integrated Technologies and Modern Features
According to the technical information for the DA25 series, this system includes several essential features:
- Automatic defrosting
- Automatic restart
- 24h timer
- Eco and turbo modes
- Self-cleaning
- Motion and humidity sensor
- Biofilter to improve air quality
- Optional WiFi (smart home compatible)
In several installations in Boucherville, our clients opted for the WiFi module to manage the temperature remotely, which is particularly useful for secondary residences or rental properties.
HVAC Installation: What You Need to Know Before Choosing
Critical Points Often Overlooked
At AirGreen, we have observed several common mistakes:
- Incorrect capacity selection per room
- Poor management of piping lengths
- Inadequate positioning of indoor units
The DIRECT AIR DA25 allows for:
- Up to 60 meters of total piping
- Multi-level installation
- Flexibility for complex renovations
But without professional installation, these benefits can be compromised.

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 3 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.
