A Discreet and High-Performance HVAC Solution for Quebec's Harsh Winters

In the field of HVAC in Montreal, Laval, Longueuil, North Shore, and South Shore, certain solutions clearly stand out when it comes to combining performance, discretion, and energy efficiency. The DIRECT AIR Heat Xtreme Pro -35°C | 24000 BTU ceiling cassette is one of those systems that we regularly recommend at AirGreen, especially for high-end residential projects, businesses, and multi-unit dwellings.

This specific model addresses a well-known reality in Quebec: demanding winters, where the real performance of a heat pump makes all the difference between constant comfort and costly discomfort.


Why choose a ceiling cassette rather than a classic wall-mounted unit?

Optimal Aesthetic Integration

Unlike visible wall-mounted units, the ceiling cassette integrates directly into the suspended ceiling. The result:

  • No visual impact on walls
  • Uniform 360° air distribution
  • Ideal for open spaces (living rooms, offices, businesses)

During an HVAC installation in Laval at a recently renovated restaurant, our team chose this model precisely to eliminate any visual obstruction. The client wanted an invisible… and effective system. Mission accomplished.


Extreme performance down to -35°C: an essential criterion in Quebec

One of the most decisive elements of this model is its ability to maintain stable heating down to -35°C.

Specifically:

  • Reliable heating even during extreme cold spells
  • Significant reduction in reliance on auxiliary systems
  • Constant comfort in all areas

According to manufacturer data, the Heat Xtreme Pro series operates in an impressive temperature range from -35°C to 30°C for heating.

At AirGreen, we installed this model in a house in Longueuil, where the client previously experienced significant heat loss with an old heat pump. After installation, thermal stability was immediate, even in January.
