AirGreen case study: installation in Longueuil

We recently installed a DirectAir DA25 12,000 BTU in a condo in Longueuil.

Initial situation

• 600 sq. ft. condo
• Inefficient old electric system
• Uneven heating issues in winter

Proposed solution

• Wall-mounted installation in the living room
• Standard piping run (15 feet)
• Optimized positioning to cover living room + bedroom

Result

• Energy bill reduction of approximately 30%
• Stable temperature throughout the space
• Very low indoor sound level

This type of project represents exactly the ideal use case for this heat pump.

HVAC installation: what you need to know

At AirGreen, a standard installation includes:

• Wall bracket or outdoor base
• Up to 15 feet of piping
• Electrical connection
• Complete commissioning
• Performance test

Important technical points

• The model uses a 1/4 - 1/2 line, standard for this type of unit
• Compact dimensions:
  • Indoor: 31.30 × 8.86 × 11.61 in
  • Outdoor: 30.12 × 11.93 × 21.85 in

These dimensions facilitate installation in confined spaces, particularly on balconies in Montreal.

Common mistakes to avoid

1. Incorrect sizing

A 12,000 BTU unit is perfect for a specific space. Installing this model in too large an area will result in:

• Premature wear
• Insufficient comfort in winter

2. Poor indoor unit placement

An installation that is too low or poorly oriented reduces the efficiency of air diffusion.

3. Neglecting HVAC maintenance

Even a reliable unit like the DirectAir DA25 requires:

• Annual cleaning
• Filter check
• Drainage inspection

At AirGreen, we offer HVAC maintenance plans tailored to all our clients on the North Shore and South Shore.

Subsidies and savings

This model is eligible for a LogisVert grant of $450 (updated November 2025).
