A high-performance and discreet ducted solution for optimal comfort in Montreal

At AirGreen, we regularly install ducted HVAC systems in properties where aesthetics, performance, and uniform comfort are essential. The DIRECT AIR DA25 | 18000 BTU ducted heat pump (vertical) stands out as a particularly suitable solution for modern homes, high-end condos, and small commercial spaces in Montreal, Laval, Longueuil, on the North Shore and the South Shore.

This model combines centralized air distribution, heating capacity down to -25°C, and flexible installation, making it a strategic choice for demanding homeowners.


Why choose a DIRECT AIR DA25 vertical ducted heat pump?

Invisible integration, but very real performance

Unlike wall-mounted units, this ducted heat pump is installed in a ceiling, a technical closet, or a mechanical room. It feeds a duct network, allowing for homogeneous air diffusion in several rooms.

Key Advantages:

  • No visible devices in main rooms
  • Uniform temperature distribution
  • Ideal for high-end renovations or new constructions
  • Compatible with existing centralized systems

During a recent project in Boucherville (South Shore), we replaced an old electric system with this DIRECT AIR unit. The result: a significant reduction in temperature variations between floors, and an immediate improvement in perceived comfort.


Detailed technical specifications: DIRECT AIR DA25 18000 BTU

Performance adapted to the Quebec climate

This heat pump is designed to operate efficiently in Quebec's climate conditions:

  • Heating capacity: up to -25°C
  • Cooling capacity: 18,000 BTU
  • Power at -15°C: 13,000 BTU
  • COP at -8°C: 12.43
  • Refrigerant: R-410A
  • Voltage: 220V

According to the official brochure, DIRECT AIR systems offer stable operation for heating down to -25°C and cooling up to 50°C, which largely covers the needs of residences in Montreal, Laval, and Longueuil.


Energy efficiency and performance

Even if this model is not Energy Star Cold Climate certified, it remains efficient:

  • SEER2: 120.030
  • HSPF2: 110.615
  • EER2: 112.520

These values demonstrate solid efficiency for a ducted system, particularly in the context of a well-sized installation.


Dimensions and installation

Indoor unit (vertical):

  • 34.65 × 28.53 × 8.27 inches

Outdoor unit:

  • 35.04 × 13.46 × 26.50 inches

Piping:

  • 1/4 – 1/2 inches

This configuration allows for a relatively compact installation for a ducted unit, a major advantage in townhouses or condos.


Integrated technologies and features

Smart comfort and automation

The DIRECT AIR series offers several useful functions:

  • Auto Restart
  • Auto Defrost
  • 24-hour Timer
  • Optional WiFi (smart home compatible)

During an installation in Laval, a client wanted to control their system remotely via their phone. Adding the WiFi module allowed for complete temperature management, even when on the go.


Advanced air management and static pressure

A key advantage of ducted units is their ability to manage static pressure:

  • Adjustable external static pressure
  • Optimized distribution according to the duct network
  • Adaptability to complex configurations

This allows AirGreen to customize each installation according to the building's reality.


AirGreen Installation: Field Expertise and Technical Precision

Real-life example of installation in Montreal

In a duplex in Montreal (Rosemont), we installed this unit to replace an electric baseboard system:

Challenges encountered:

  • Limited mechanical space
  • Duct network to be created entirely
  • Insulation to be optimized

Solutions provided:

  • Vertical installation in a technical closet
  • Compact ducts with reinforced thermal insulation
  • Static pressure adjustment for perfect balancing

Result:

  • Uniform comfort in all rooms
  • Significant reduction in energy consumption
  • No visual impact in living spaces

Common mistakes to avoid

In the field of HVAC in Montreal, certain mistakes often recur:

  • Undersizing BTU capacity
  • Neglecting duct network design
  • Ignoring required static pressure
  • Installing without precise thermal load calculation

At AirGreen, every project is preceded by a complete analysis, which guarantees optimal system performance.


Subsidies and profitability

LogisVert Subsidy

This model is eligible for a subsidy of:

  • $630 (updated: November 26, 2025)

Even though this aid is more modest than for some Cold Climate models, it helps reduce the overall cost of the project.


Return on investment

In several projects carried out in Longueuil and on the North Shore, clients observe:

  • Decrease in heating costs
  • Improvement in overall comfort
  • Property value appreciation

A well-installed ducted system represents a sustainable investment.
