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

At AirGreen, we regularly install multi-zone systems in residential properties and small apartment buildings in Montreal, Laval, Longueuil, on the North Shore, and the South Shore. The 2-zone DIRECT AIR HEAT XTREME PRO (-35°C) heat pump with a 36,000 BTU outdoor unit is one of the models we recommend when our clients are looking for an optimal balance between extreme winter performance, installation flexibility, and energy efficiency.

This system is specifically designed to operate in harsh climatic conditions, with heating capacity maintained down to -35°C, an essential feature in our Quebec reality.


Real Heating and Cooling Performance: Beyond the Numbers

Capacity tailored to the real needs of Quebec homes

With a nominal capacity of 36,000 BTU, this heat pump is ideal for:

  • Medium-sized single-family homes
  • Duplexes or triplexes with distinct zones
  • Condos with differentiated needs (living room + bedrooms)

In practice, we recently installed this model in a duplex in Boucherville, where the owners wanted to:

  • Efficiently heat two independent floors
  • Reduce their reliance on electric baseboard heaters
  • Maintain constant comfort even during cold spells

Result: a significant reduction in energy consumption and stable temperature even during a period of -27°C.

Advanced energy efficiency

This model offers high performance:

  • SEER2: 22+ (depending on configuration)
  • High HSPF2
  • COP of 1.93 at -8°C (according to provided data)

These indicators translate concretely into:

  • Significant energy savings
  • Improved efficiency in continuous heating
  • Eligibility for subsidy programs

Heat Xtreme PRO Technology: Designed for the Canadian Climate

Operation down to -35°C

Unlike many standard systems, this heat pump continues to provide efficient heating at very low temperatures. This means:

  • Less reliance on backup systems
  • Constant thermal comfort
  • Better long-term profitability

According to the brochure, the system operates within a range of:

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

Intelligent defrosting and restart

In our installations in Laval and Repentigny, we observe that:

  • Automatic defrosting reduces performance losses
  • Automatic restart protects the system during power outages

These technical details make a significant difference in winter.


Multi-zone Configuration: Maximum Flexibility

2 independent zones

This system allows connecting two indoor units, with individual control:

  • Independent temperature per room
  • Optimization of energy consumption
  • Personalized comfort

Possibility of expansion up to 4 zones

The DIRM-36HXPRO28-4Z outdoor unit allows for future expansion:

  • Up to 4 zones maximum
  • Ideal for scalable projects

In a project in Montreal (Rosemont), we initially installed this system with 2 zones, with preparation for a 3rd zone in the future. This strategy reduces short-term costs while maintaining flexibility.


Air Quality and Advanced Indoor Comfort

Intelligent air management

Compatible wall units offer:

  • Vertical and horizontal automatic louvers
  • Uniform air distribution
  • Elimination of cold zones

The louvers also have a position memory, improving daily comfort.

Integrated advanced functions

Among the important features:

  • Humidity sensor
  • Motion sensor
  • Energy-saving mode
  • Turbo mode
  • "Follow me" function (optimization based on remote control position)

These options are particularly useful in modern open-plan homes.


AirGreen Installation: What Makes the Difference

An installation adapted to each building

At AirGreen, we never perform standardized installations without analysis. For this type of heat pump, we evaluate:

  • Room distribution
  • Actual thermal load
  • Optimal unit positioning
  • Piping length (important for performance)

Concrete example on the North Shore

In a house in Blainville, we:

  • Installed a 12,000 BTU unit in the living room
  • Installed an 18,000 BTU unit upstairs
  • Optimized piping to minimize losses

Result:

  • Better heat distribution
  • Noise reduction
  • Maximum system efficiency

Subsidies and Return on Investment

LogisVert subsidy

This model is eligible for a subsidy of:

  • $3,960 (updated November 26, 2025)

This significantly reduces the acquisition cost.

Observed real savings

For several clients:

  • 30% to 50% reduction in heating costs
  • Payback in a few years
  • Increase in property value

Important Technical Characteristics to Consider

Key Data

  • Capacity: 36,000 BTU
  • Refrigerant: R-410A
  • Voltage: 220V
  • Outdoor sound level: 63 dB(A)
  • AHRI: 207743791
  • ENERGY STAR (cold climate): Yes

Dimensions and Installation

  • Exterior dimensions: 37.48 x 16.34 x 52.48 in
  • Wall-mounted or floor stand installation
  • Compatible with multiple indoor models

Common Mistakes to Avoid

1. Undersizing indoor units

An incorrect calculation can lead to:

  • Poor performance
  • Overconsumption
  • Premature wear

2. Incorrect multi-zone configuration

The brochure clearly states that:

  • The total capacity of indoor units must adhere to a specific ratio

Incorrect sizing reduces overall performance.

3. Non-optimized installation

We have often corrected installations where:

  • Units were poorly positioned
  • Refrigerant lines were too long
  • Drainage was poorly designed

Result: loss of efficiency and recurring problems.
