A high-performance multi-zone solution designed for Quebec's harsh winters

At AirGreen, we daily install systems capable of meeting the climatic realities of Montreal, Laval, Longueuil, the North Shore, and the South Shore. The 4-zone DIRECT AIR HEAT XTREME PRO 48,000 BTU heat pump precisely fits this logic: offering reliable heating down to -35°C, while ensuring efficient air conditioning in summer.

This multi-zone model can power up to 4 distinct zones (expandable to 5) with a single outdoor unit. This means independent temperature management in different rooms — an ideal solution for multi-story homes, multiplexes, or ductless renovations.


Extreme performance and advanced energy efficiency

Guaranteed operation down to -35°C

One of the main challenges our Quebec clients face is the performance of heat pumps during severe cold spells. This HEAT XTREME PRO model is designed to operate efficiently even in extreme conditions.

According to the official brochure, the heating operating range extends from -35°C to 30°C, positioning it among the most reliable systems for our climate.

Key data:

  • Heating capacity at -15°C: 45,000 BTU
  • Capacity at -8°C: 36,000 BTU
  • COP at -8°C: 12.03
  • HSPF2: 19.815
  • SEER2: 121.830

These performances significantly reduce reliance on electric auxiliary systems, leading to real savings on energy bills.


ENERGY STAR® Certification and Grant Eligibility

This heat pump is ENERGY STAR® and ENERGY STAR® Cold Climate certified, making it eligible for programs such as LogisVert.

  • Estimated grant: $4320 (2025 update)
  • AHRI Number: 207743794
  • ENERGY STAR ID: 2473685

At AirGreen, we assist our clients with all procedures to maximize these financial aids, particularly in Montreal and Montérégie, where programs are particularly advantageous.


Multi-zone flexibility: personalized comfort in every room

4-zone configuration (up to 5 zones)

This heat pump allows connecting multiple indoor units:

  • Wall-mounted
  • Consoles
  • Ceiling cassettes
  • Ducted (concealed)

As indicated in the brochure, all indoor units are compatible with multi-zone systems, offering maximum flexibility.

Real AirGreen example:
We recently installed this system in a duplex in Laval:

  • 1 unit in the living room
  • 1 in each bedroom (2)
  • 1 in the basement

Result:

  • Stable temperature in each space
  • 38% reduction in annual energy bill
  • No perceptible noise in the bedrooms

Critical sizing rule

A point often overlooked by inexperienced installers concerns the capacity distribution between zones.

The brochure clearly specifies the following rule:

Outdoor capacity × 0.66 ≤ indoor total ≤ Outdoor capacity × 1.33

At AirGreen, we consistently adhere to this rule to avoid:

  • Loss of heating performance
  • Inefficient cycles
  • Premature compressor wear

Everyday comfort and technology

Smart Air Distribution

This heat pump is equipped with:

  • Automatic vertical louvers
  • Automatic horizontal louvers
  • Position memory function

This allows for homogeneous air distribution in each room, without cold spots or unpleasant drafts.


Silence and discretion

  • Indoor sound level: 28 to 41 dB(A)
  • Outdoor sound level: 65 dB(A)

In several installations in Longueuil, our clients have been surprised by the system's quietness, especially in night mode.


Advanced Features

Indoor units include (according to the brochure):

  • Auto restart
  • Smart defrost
  • Turbo mode
  • Eco mode
  • Motion detector
  • Humidity detector
  • "Follow me" function
  • Self-cleaning
  • Biofiltration

WiFi is available as an option, compatible with smart home systems like Google and Alexa.

Concrete example on the South Shore

In a single-family home in Boucherville, we replaced an aging central system with this multi-zone heat pump.

Challenges encountered:

  • Absence of ducts
  • Uneven heat distribution
  • Loud noise from the old system

Solution:

  • Installation of 4 wall-mounted units
  • Optimization of refrigerant lines
