A reliable and efficient multi-zone solution for Quebec residences
At AirGreen, we regularly install multi-zone systems in homes, condos, and plexes in Montreal, Laval, Longueuil, on the North Shore, and the South Shore. The DIRECT AIR DA25 (18,000 BTU) 2-head heat pump stands out as a balanced solution between performance, ease of installation, and controlled cost.
Designed to operate down to -25°C, this heat pump meets Quebec's climatic requirements while efficiently air conditioning two distinct zones with a single outdoor unit.
Why choose a 2-zone heat pump like the DIRECT AIR DA25?
A solution adapted to the realities of Quebec homes
In many projects we undertake in Montreal and Montérégie, clients seek to air condition two strategic areas:
- Living room + master bedroom
- Ground floor + basement
- Office + open concept area
A dual-zone heat pump like the DA25 allows for:
- Independent temperature management
- A reduction in the number of outdoor units
- A cleaner and more aesthetic installation
AirGreen concrete example
During a project in Boucherville (South Shore), a client was hesitating between two independent wall-mounted systems or a multi-zone solution. After analysis:
- The 2-head configuration allowed for savings on electrical installation
- Less outdoor space used
- Better visual integration on the rear facade
Result: a more harmonious system and immediate customer satisfaction.
Performance and energy efficiency
Capacity and efficiency
- Nominal power: 18,000 BTU
- Capacity at -8°C: 14,300 BTU

HVAC installation: what you need to know
Dimensions and constraints
- Outdoor unit: 35.04 × 13.46 × 26.50 in
- Outdoor sound level: 58.5 dB(A)
- Voltage: 220V
- Maximum piping length: up to 40 m depending on configuration
Important rules in multi-zone
A frequently overlooked point:
The total capacity of the indoor units must remain between 66% and 133% of the outdoor capacity.
At AirGreen, we have already corrected poorly sized installations done by other contractors, causing:
- Loss of heating performance
- Inefficient cycles
- Premature wear
Our approach
For each project in Montreal or Laval, we:
- Calculate the actual thermal load
- Validate head combinations
- Optimize BTU distribution
Sound level and daily comfort
- Indoor: 22.5 to 36 dB(A)
- Outdoor: 58.5 dB(A)
This sound level is ideal for:
- Bedrooms
- Home offices
- Condos with close neighbors
In a project in Rosemont, a client working from home specifically chose this model for its quietness. After installation, no noise disturbance was reported.
Concrete advantages observed in our clients
1. Reduced energy costs
