A Heat Pump Designed for Quebec's Extreme Winters

At AirGreen, we know that an HVAC system must be reliable, efficient, and perfectly suited to Quebec's climatic realities. The DirectAir Heat Xtreme Pro 18,000 BTU wall-mounted heat pump stands out as a particularly attractive solution for residential properties and small commercial spaces in Montreal, Laval, Longueuil, on the North Shore and the South Shore.

This model is primarily distinguished by its ability to maintain heating performance down to -35 °C, an essential criterion in our market. Unlike many standard heat pumps that quickly lose efficiency below -20 °C, this unit ensures stable performance even during periods of extreme cold.

Technology and Smart Comfort in Everyday Life

Optimized Operation for the Quebec Climate

According to the manufacturer's brochure, this series can operate within the following ranges:

  • Air Conditioning: -30 °C to 50 °C
  • Heating: -35 °C to 30 °C

This means that even during periods of extreme cold in Montreal or Laval, the system continues to provide stable heat.

Integrated Smart Functions

This heat pump includes several advanced technologies:

  • Integrated WiFi (smart home compatible)
  • Automatic Restart
  • Automatic Defrost
  • Eco Mode and Turbo Mode
  • Motion Detector
  • Humidity Sensor for Optimal Comfort
  • Self-Cleaning

We have installed several similar units on the South Shore, notably in Boucherville and Longueuil, where customers particularly appreciate remote management via phone.

Precise Air Distribution Control

  • Vertical Louvers: Auto
  • Horizontal Louvers: Auto

This dual automatic control ensures uniform air distribution, preventing cold or overheated zones in the room.

Feedback: Real Installation in Laval

During a recent project in Laval, a client had an old heat pump that was inefficient below -15 °C. The result was:

  • High electricity consumption
  • Frequent use of auxiliary heating
  • Discomfort in distant rooms

After the installation of the DirectAir Heat Xtreme Pro 18,000 BTU, the results were immediate:

  • Reduction in energy bill by approximately 28%
  • Constant comfort even at -25 °C
  • Significantly improved air distribution thanks to automatic louvers

This type of transformation is typical when replacing a standard system with a heat pump adapted to the Canadian climate.
