An Efficient HVAC Solution Adapted to Quebec Winters

At AirGreen, we see daily how choosing an efficient wall-mounted heat pump can transform a home's comfort, particularly in demanding regions like Montreal, Laval, Longueuil, the North Shore, and the South Shore. The DirectAir 23 SEER Wall-Mounted Heat Pump – 18,000 BTU fits perfectly into this logic: offering a solid balance between energy efficiency, reliability, and controlled acquisition cost.

This model is for owners looking for a reliable HVAC solution capable of operating efficiently down to -25°C, while maintaining optimized energy consumption thanks to its ENERGY STAR® and Cold Climate certifications.


Detailed Technical Analysis: What This Model Truly Offers

Energy Performance and Efficiency

The DirectAir 23 SEER boasts remarkable performance in its category:

  • SEER2: 23 (up to 25.5 depending on configuration)
  • HSPF2: 18.615
  • EER2: 13.020
  • COP at -8°C: 11.83

These figures concretely translate to:

  • A significant reduction in electricity costs
  • An ability to maintain stable performance even during cold periods
  • Consistent air conditioning performance during the humid summers of Montreal and Longueuil

Actual Capacity and Power

  • Nominal Power: 18,000 BTU
  • Heating at -15°C: 11,900 BTU
  • Heating at -8°C: 10,000 BTU
  • Cooling: 18,000 BTU

In practice, this capacity is perfectly suited for:

  • Condos
  • Medium-sized single-family homes
  • Entire floors requiring independent thermal management

A Design Focused on Daily Comfort

Intelligent Air Distribution

A point often underestimated by clients is airflow management. On this model:

  • Vertical Louvers: Auto
  • Horizontal Louvers: Auto

This allows for:

  • Uniform air distribution
  • Fewer cold or hot spots
  • Constant comfort without frequent manual adjustments

During our installations in Laval, several clients noted an immediate improvement in comfort in open-plan areas, particularly in kitchen-living room spaces.


Advanced Operating Modes

The DirectAir DA25 series integrates several practical modes:

  • ECO Mode: automatic consumption reduction
  • Turbo Mode: rapid temperature rise or fall
  • Sleep Mode: quiet and optimized night operation
  • 24h Timer
  • Automatic Restart
  • Automatic Defrost

An important detail: the integrated humidity sensor automatically adjusts parameters to maintain a stable comfort level, particularly useful during humid summers on the South Shore.


HVAC Installation: AirGreen Field Experience Feedback

Real Case – Installation in Boucherville (South Shore)

We recently installed this model in a semi-detached house in Boucherville. The client had three priorities:

  1. Reduce heating costs
  2. Eliminate temperature variations
  3. Obtain a quiet solution

Result after installation:

  • Noticeable decrease in energy bill from the first month
  • Stable temperature between floors
  • Outdoor noise level of 55 dB(A) deemed very discreet

What We Include in a Standard Installation

At AirGreen, a professional HVAC installation includes:

  • Complete electrical connection
  • Up to 15 feet of tubing (1/4 - 1/2)
  • Wall bracket or ground base
  • Startup and full calibration
  • Performance testing under real conditions

Common mistakes to avoid:

  • Under-sizing the BTU capacity
  • Installing the indoor unit too close to the ceiling
  • Neglecting drainage evacuation

These errors can significantly reduce the actual performance of the heat pump.


Subsidy and Profitability in Quebec

This model is eligible for:

  • LogisVert Subsidy: $500

Even if this amount may seem modest, combined with:

  • Reduced consumption
  • High efficiency

The overall profitability remains attractive, especially over a 5 to 10-year horizon.
