A Multizone HVAC Solution Designed for Quebec's Demanding Climate

At AirGreen, we daily install HVAC systems tailored to the climatic realities of Montreal, Laval, Longueuil, the North Shore, and the South Shore. The DIRECT AIR HEAT XTREME PRO (-35°C) 2-zone heat pump stands out as a reliable solution for properties requiring precise control of two distinct spaces, while maintaining stable performance even during harsh winters.

This model, featuring an 18,000 BTU outdoor unit, allows for the connection of two wall-mounted indoor units (6,000, 9,000, or 12,000 BTU), offering true flexibility for multi-story homes, condos, or duplexes.


Extreme Performance Down to -35°C: An Essential Criterion in Quebec

Advanced Heating Capacity for the Canadian Winter

The main strength of this heat pump lies in its ability to maintain efficient performance down to -35°C, a critical threshold for installations in Montérégie, Laval, or on the North Shore.

Unlike many standard models that rapidly lose efficiency below -15°C, this system:

  • Still provides 15,000 BTU at -8°C
  • Can reach up to 19,700 BTU at -15°C
  • Maintains thermal stability even during long cold spells

According to the manufacturer's technical specifications, the Heat Xtreme Pro series is specifically designed to operate within a range of -35°C to 30°C for heating, making it a perfectly suited option for the Quebec climate.

Energy Efficiency and Certifications

This model is certified:

  • ENERGY STAR®
  • ENERGY STAR® Cold Climate
  • AHRI: 207743785

With solid performance:

  • SEER2: 22+ (up to 25 depending on the series)
  • HSPF2: 19.815
  • COP at -8°C: 1.93

This means real savings on energy bills, especially for homeowners replacing traditional electric heating.


2-Zone Configuration: Flexibility and Personalized Comfort

Smart Heat and Air Conditioning Distribution

A 2-zone heat pump allows independent control of two distinct spaces:

  • Master bedroom + living room
  • Ground floor + upstairs
  • Office + living area

Each indoor unit can be adjusted according to specific needs, avoiding energy losses associated with uniform heating.

Combination Rules and Optimization

The system adheres to precise capacity rules to ensure optimal performance:

  • Total indoor capacity between 66% and 133% of outdoor capacity
  • Common example installed by AirGreen:
    • 1 x 12,000 BTU + 1 x 9,000 BTU on an 18,000 BTU unit

In our installations in Longueuil and Boucherville, this configuration is frequently used to maximize comfort without oversizing the system.

  • Result:
    • 35% reduction in heating costs
    • Uniform thermal comfort
    • Very low noise level in the bedrooms

Critical Points Mastered by Our Teams

During installation, several errors must be avoided:

  • Incorrect BTU distribution between zones
  • Excessive piping length
  • Inadequate positioning of wall units
  • Poorly designed drainage

At AirGreen, our certified refrigeration technicians ensure:

  • Installation compliant with RBQ standards
  • Optimization of energy efficiency
  • A clean and durable finish

Subsidies and Return on Investment

Medium-Term Profitability

For a typical household in Montreal:

  • Annual savings: $800 to $1,500
  • Return on investment: 3 to 5 years
  • Average lifespan: 12 to 15 years

Connectivity and Modern Comfort

The system offers a WiFi option compatible with Google Home and Alexa, allowing for:

  • Remote control
  • Smart programming
  • Real-time energy optimization

In several installations on the South Shore, our customers use this feature to adjust the temperature before returning home.
