A Multi-Zone HVAC Solution Designed for Quebec's Extreme Winters

In the demanding climate of Montreal, Laval, Longueuil, the North Shore, and the South Shore, choosing a heat pump capable of maintaining high heating performance down to -35°C is not a luxury, but a necessity. At AirGreen, we have installed several DIRECT AIR HEAT XTREME PRO systems in residences and multi-unit buildings, and this 2-zone 48,000 BTU model stands out as a reliable, high-performance, and cost-effective solution.

This multi-zone heat pump can power two distinct areas with a single outdoor unit, while maintaining flexibility for up to 5 zones maximum as needs evolve.


Real Heating and Cooling Performance: More Than Just a Spec Sheet

Capacity and Energy Efficiency

The DIRECT AIR HEAT XTREME PRO 48,000 BTU Heat Pump offers:

  • Cooling Capacity: 48,000 BTU
  • Power at -15°C: 45,000 BTU
  • Power at -8°C: 36,000 BTU
  • SEER2: 21.830
  • HSPF2: 19.815
  • EER2: 11.720
  • COP at -8°C: 12.03

These figures indicate excellent efficiency for an HVAC installation in Montreal, especially in winter. According to technical documentation, Heat Xtreme Pro systems maintain stable heating operation down to -35°C, with an operational range from -35°C to 30°C for heating and -30°C to 50°C for cooling.

Concrete Example of an AirGreen Installation

In Boucherville (South Shore), we recently installed this model in a multi-generational home. The client wanted:

  • Stable temperature in the main dwelling
  • Independent control for the basement

Thanks to the 2-zone configuration, we installed:

  • An 18,000 BTU wall-mounted unit on the ground floor
  • A 12,000 BTU wall-mounted unit in the basement

Result: a 32% reduction in heating bills from the first winter, while maintaining constant comfort, even during cold snaps.


Multi-zone Flexibility: An Evolving and Smart Solution

Configuration and Combination Rules

The DIRECT AIR multi-zone system allows different indoor units (wall-mounted, consoles, ceiling cassettes, etc.) to be connected. An essential rule to follow:

  • Total indoor capacity = between 66% and 133% of outdoor capacity

This optimizes overall performance without overloading the compressor.

Compatible Unit Types

  • Classic wall-mounted units (most commonly installed in Montreal)
  • Wall-mounted consoles for basements
  • 4-way ceiling cassettes for open spaces
  • Ducted units for more complex projects

At AirGreen, we always recommend a personalized analysis to choose the ideal combination based on the building's surface area and configuration.


Advanced Comfort: More Than Just Heating and Cooling

Smart Air Distribution

This model offers automatic control:

  • Vertical vanes: Auto
  • Horizontal vanes: Auto

This ensures uniform air distribution, preventing cold or hot spots.

Integrated Technologies

Indoor units include:

  • Automatic restart
  • Automatic defrost
  • 24h timer
  • Humidity sensor
  • "Follow me" function
  • Self-cleaning
  • Motion sensor

These features allow for intelligent comfort management, particularly useful in modern homes in Laval and Longueuil.


HVAC Installation: What Our Clients Absolutely Need to Know

AirGreen Standard Installation

When installing this 2-zone heat pump, we typically include:

  • Up to 15 feet of refrigerant tubing
  • Complete electrical connections
  • Wall or ground mount for the outdoor unit
  • Full commissioning

Common Mistakes to Avoid

After several hundred HVAC installations, we often observe:

  • Undersizing of indoor units
  • Incorrect positioning of wall-mounted units
  • Ignoring building heat losses

In Montreal, where temperature variations are significant, incorrect configuration can considerably reduce system performance.


Noise Level and Acoustic Comfort

  • Indoor: 28 to 41 dB(A) (very quiet)
  • Outdoor: 65 dB(A)

During a recent project in Laval, a client was replacing an old noisy heat pump. After installing the DIRECT AIR model:

  • Significant reduction in outdoor noise
  • Improved indoor comfort, especially at night

Subsidies and Profitability in Quebec

This model is eligible for:

  • LogisVert Subsidy: up to $4320

Thanks to its certification:

  • ENERGY STAR®
  • ENERGY STAR® Cold Climate
  • AHRI: 207743794

This makes it an excellent choice for maximizing savings in government programs.


Reliability, Warranty, and Durability

  • Warranty: 10 years compressor / 10 years parts / 0 year labor (standard)
  • Extended warranty option available

According to manufacturer specifications, Direct Air heat pumps are designed to high Canadian standards, offering superior durability and recognized reliability.

At AirGreen, we have observed:

  • Very few service calls for this range
  • Excellent stability even after several harsh winters
