A Reliable and Efficient HVAC Solution for Quebec's Climate

At AirGreen, we install hundreds of wall-mounted heat pump systems in Montreal, Laval, Longueuil, on the North Shore and South Shore every year, and certain models stand out for their balance of cost, performance, and reliability. The DirectAir DA25 18,000 BTU Wall-Mounted Heat Pump is one of these solutions that we recommend in specific contexts.

This model offers solid heating capacity down to -25°C, stable performance, and modern features adapted to the real needs of Quebec residences.


Real Performance in Heating and Air Conditioning: What You Need to Know

Capacity Adapted to Montreal and Surrounding Areas

The DirectAir DA25 18,000 BTU is designed to offer consistent performance:

  • Cooling: 18,000 BTU
  • Heating down to -25°C
  • Power at -15°C: 11,300 BTU
  • Power at -8°C: 14,900 BTU

These figures are particularly important in our field reality. During several installations on the South Shore (Boucherville, Longueuil), we observed that this heat pump allowed for stable comfort even during cold periods without excessive reliance on auxiliary heating.

Energy Efficiency

  • SEER2: 23.5
  • HSPF2: 11.0
  • EER2: 12.5
  • COP at -8°C: 2.3

These performances ensure controlled electricity consumption, especially in mid-season, where savings are most significant.


Technical Design Focused on Durability

DirectAir heat pumps are designed according to high Canadian quality standards, with particular attention to durability and reliability.

Key Technical Specifications

  • Refrigerant: R-410A
  • Voltage: 220V
  • Piping: 1/4 - 1/2
  • Outdoor Sound Pressure: 58 dB(A)
  • Compact Dimensions (Indoor): 37.99 × 9.41 × 12.56 in

During a recent installation in Laval, a client was looking for a discreet unit for an open living room. The low noise level and compact size were decisive in their choice.


Smart Comfort and Advanced Features

Optimized Air Management

A point often overlooked by buyers: air direction.

  • Vertical Louvers: Auto
  • Horizontal Louvers: Auto

This means automatic and uniform air distribution, which prevents cold or hot spots in the room.

This series includes:

  • Automatic restart
  • Intelligent defrosting
  • Eco mode and turbo mode
  • Motion detector
  • Humidity sensor
  • "Follow Me" function

In several projects in Montreal, these features have improved comfort without constant client intervention.


Concrete Example of an AirGreen Installation

Real Project in Longueuil – Single-Family Home

We recently installed a DirectAir DA25 18,000 BTU in a 1,400 sq. ft. house:

Initial Situation:

  • Expensive electric heating
  • No air conditioning
  • Poor air circulation on the ground floor

Proposed Solution:

  • Wall-mounted installation in the central zone
  • 20-foot piping run (slight extra cost)
  • Outdoor wall bracket to prevent snow accumulation

Result:

  • Significant reduction in electricity costs
  • Uniform comfort throughout the main area
  • Very low indoor noise

Grants and Return on Investment

This heat pump is eligible for a LogisVert grant of $745 (updated 2025).

In our internal analyses, for a typical property in Montreal or Laval, this allows for:

  • A return on investment in 3 to 5 years
  • A significant reduction in reliance on electric baseboards

HVAC Installation: Critical Elements Not to Be Overlooked

Frequent Errors We Often Correct

  • Incorrect positioning of the indoor unit
  • Poorly designed drainage
  • Excessive piping length without recalibration
  • Inadequate outdoor support

At AirGreen, every HVAC installation is adapted:

  • Thermal analysis of the building
  • Strategic positioning
  • Compliance with RBQ standards
