A High-Performance Multi-Zone Solution for Precise Comfort in Every Space
At AirGreen, we regularly install multi-zone systems in homes and condos in Montreal, Laval, Longueuil, on the North Shore and the South Shore. The DIRECT AIR DA25 36,000 BTU 2-head heat pump stands out as a particularly attractive option for homeowners looking to efficiently and reliably control the temperature of two distinct zones, even in demanding winter conditions.
This model combines heating capacity down to -25°C, a flexible multi-zone configuration, and solid energy performance, adapted to Quebec's climatic realities.
Why choose a 2-head heat pump like the DIRECT AIR DA25?
Independent control of two zones
A 2-head installation allows two distinct indoor units to be connected to a single outdoor unit. This offers several concrete advantages:
- Precise temperature adjustment in each room
- Reduction of unnecessary energy loss
- Optimized comfort for different uses (e.g., living room vs. bedroom)
In several projects carried out in Boucherville and Laval, we have installed this type of system for multi-story homes, allowing for a thermal balance impossible to achieve with a classic central system.
Heating performance down to -25°C
Quebec's climate imposes high demands. The DA25 series is designed to operate efficiently:
- Heating down to -25°C
- Capacity maintenance at low temperatures
- Integrated automatic defrosting
According to technical data, this series operates within a range of -25°C to 30°C for heating and up to 50°C for air conditioning, ensuring reliable year-round use.

An HVAC Installation Adapted to Montreal's Realities
Real-world example: installation in Longueuil (renovated duplex)
We recently installed a DIRECT AIR DA25 2-head system in a duplex in Longueuil:
- Zone 1: living room + open kitchen (12,000 BTU)
- Zone 2: master bedroom (9,000 BTU)
Challenges encountered:
- Piping through a load-bearing wall
- Optimizing drainage without a pump
AirGreen Solution:
- Use of discreet exterior conduits
- Adjustment of positioning to maximize air circulation
Result:
- Stable comfort in both zones
- Significant reduction in short cycling
- Client satisfied with sound discretion (22.5 to 36 dB indoor)
Multi-zone Installation: Important Technical Rules
A commonly misunderstood point concerns the total capacity of the indoor units.
According to manufacturer specifications:
- Minimum capacity: 66% of outdoor capacity
- Maximum capacity: 133%
This means that improper sizing can lead to:
- Loss of heating performance
- Uneven air distribution
At AirGreen, we systematically analyze:
- The actual surface area
- Insulation
- Sun exposure
- Occupancy habits
Advanced Features That Make a Difference
Smart Comfort
- "Follow Me" function: adjusts temperature based on the remote control
- Humidity sensor: improves perceived comfort
- Biofilter: better indoor air quality
Connectivity (WiFi option)
Compatible with:
- Google Home
- Alexa
- Smart home systems
This allows for convenient remote control, especially for secondary residences or rental properties.
Points to Consider Before Installation
What many clients don't know
-
Unit positioning is critical
Improper vane orientation drastically reduces efficiency. -
Outdoor noise must be anticipated
At 63 dB(A), poor placement can disturb neighbors. -
Drainage must be planned from the start
A common mistake is ignoring the natural slope.
