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.

High-Performance Multi-Zone Solution for Constant Comfort in Montreal, Laval, and the South Shore
At AirGreen, we regularly install multi-zone HVAC systems tailored to Quebec's climatic realities. The DIRECT AIR DA25 (48,000 BTU) 4-head heat pump represents a strategic solution for homeowners who want to air condition and heat multiple rooms with a single outdoor system, while maintaining excellent energy efficiency.
This model is designed to meet the needs of single-family homes, plexes, and modern condos in areas like Montreal, Laval, Longueuil, the North Shore, and the South Shore, where temperature variations demand reliable performance down to -25°C.
Real Performance in Quebec's Climate: What We See on the Ground
Reliable Heating Down to -25°C
This heat pump's heating capacity reaches -25°C, which is essential for Quebec's harsh winters. During our installations in areas like Boucherville or Laval-des-Rapides, we have observed that this model maintains stable performance even during prolonged periods of cold.
According to technical data from the manufacturer's brochure, Direct Air systems operate in an extended range from -25°C to 30°C for heating and up to 50°C for air conditioning. This confirms their adaptability to local seasonal extremes.
Capacity and Smart Distribution
- Total Capacity: 48,000 BTU
- Up to 4 independent zones (expandable to 5)
- Compatible with several indoor units (9K, 12K, 18K, 24K)
Concretely, this allows to serve:
- A main living room
- 2 to 3 bedrooms
- An office or finished basement
Each zone can be controlled individually, reducing unnecessary energy consumption.
A Well-Thought-Out Multi-Zone Installation: AirGreen Expertise
Real Installation Example in Longueuil
We recently installed this model in a house in Longueuil (Saint-Hubert sector). The client wanted to air condition:
- 3 upstairs bedrooms
- 1 open-plan area on the ground floor
Challenges encountered:
- Significant distance between units
- Aesthetic constraints (condo with visible facade)
AirGreen Solution:
- Optimized duct routing (fewer losses)
- Use of discreet pipe covers
- Load balancing according to the multi-zone rule (0.66 to 1.33 of total capacity)
Result:
- Uniform comfort throughout the house
- Significant reduction in energy costs from the first season
Detailed Technical Specifications
Energy Efficiency
- SEER2: 123.430
- HSPF2: 18.715
- EER2: 112.520
- ENERGY STAR® certified
These performances ensure optimized consumption, particularly for summer air conditioning in Montreal.
Heating Performance
- Power at -8°C: 34,000 BTU
- Power at -15°C: 33,000 BTU
- COP at -8°C: 11.83
This level of performance reduces reliance on electric auxiliary systems.
Advanced Indoor Comfort and Integrated Technologies
Smart Air Distribution
- Automatic vertical louvers
- Automatic horizontal louvers
- Louver position memory
This allows for homogeneous air diffusion, avoiding cold or overheated zones.
Key Features
Indoor units include:
- Turbo mode for rapid cooling
- Eco mode for energy savings
- Motion and humidity sensor
- "Follow me" function for personalized comfort
- Self-cleaning and biofilter
These elements significantly improve indoor air quality, a crucial point in urban environments like Montreal.
Noise Level: An Often Underestimated Advantage
- Indoor: as low as 22.5 dB(A)
- Outdoor: approximately 64 dB(A)
During our installations in condos in Laval or Brossard, this low noise level is particularly appreciated, especially for bedrooms.
HVAC Installation: Common Mistakes to Avoid
At AirGreen, we have identified several common mistakes:
Incorrect Zone Sizing
Incorrect BTU calculation per room leads to:
- Overconsumption
- Thermal discomfort
Excessive Duct Length
Even if the system allows up to 80 meters of total piping, poor planning reduces efficiency.
Inadequate Unit Positioning
A poorly placed unit can:
- Create dead zones
- Reduce overall performance
We systematically correct these errors through a complete analysis before installation.

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 4 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.
