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 Residences and Multi-Unit Dwellings in Quebec
In Quebec's demanding climate, choosing a reliable and efficient multi-zone heat pump is not a decision to be taken lightly. At AirGreen, we regularly install the DIRECT AIR DA25 48000 BTU 5-head heat pump, a system designed to meet the real needs of multi-zone properties in Montreal, Laval, Longueuil, the North Shore, and the South Shore.
This model stands out for its ability to power up to 5 independent zones, offering precise comfort control in each room, while maintaining remarkable energy efficiency, even at winter temperatures reaching -25°C.
A Multi-Zone Heat Pump Designed for Quebec's Climate
Capacity and Performance in Real Conditions
The DIRECT AIR DA25 48000 BTU is designed to offer stable performance in heating and air conditioning:
- Cooling Capacity: 48,000 BTU
- Heating operation down to -25°C
- Power at -15°C: 33,000 BTU
- Power at -8°C: 34,000 BTU
- COP at -8°C: 11.83
These characteristics make it a strategic choice for owners looking for a lasting solution to face the winters of Montreal and its surroundings.
According to technical documentation, this model operates efficiently in a temperature range from -25°C to 50°C for cooling and up to 30°C for heating, ensuring year-round comfort.
An Ideal Configuration for Multi-Zone Dwellings
This system allows up to 5 indoor units to be connected, which is ideal for:
- Multi-story houses
- Duplexes and triplexes
- Condos with several closed rooms
- Light commercial spaces
At AirGreen, we recently installed this model in a property in Boucherville (South Shore) comprising:
- 2 bedrooms
- 1 main living room
- 1 office
- 1 finished basement
Result: independent temperature control in each zone, significantly reducing energy loss.

These features not only improve comfort but also indoor air quality — an often underestimated element in HVAC projects in Montreal.
HVAC Installation: What You Absolutely Need to Know
A multi-zone installation requires real expertise
Unlike simple systems, a multi-zone installation requires rigorous planning.
According to manufacturer rules:
- The total capacity of indoor units must fall within a specific range
- Overload can lead to a loss of heating performance
- Poor BTU distribution can unbalance zones
At AirGreen, we have corrected several poorly configured installations by other companies in Laval and Longueuil, where:
- The indoor units were oversized
- Piping lengths were not optimized
- Sound levels were poorly managed
Concrete Example of an Error to Avoid
A client in Repentigny (North Shore) had a poorly configured multi-zone system:
- 5 indoor units totaling more capacity than the outdoor unit
- Result: insufficient heating in winter
After our intervention:
- Rebalancing of zones
- Capacity adjustment
- Airflow optimization
The client noticed an immediate improvement in comfort and a reduction in their energy bill.

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 5 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.
