A High-Performance Multi-Zone HVAC Solution Designed for Quebec Winters

In the harsh climate of Montreal, Laval, Longueuil, the North Shore, and the South Shore, choosing a heat pump capable of maintaining stable performance in extreme conditions is not a luxury, but a necessity. At AirGreen, we have repeatedly installed the 3-zone DIRECT AIR HEAT XTREME PRO 36,000 BTU heat pump, and its real-world performance confirms its reputation: reliability, constant power, and excellent multi-zone management.

This model is specifically designed to provide uniform comfort in multiple rooms, while maintaining remarkable energy efficiency, even when temperatures drop to -35°C.


Real Heating and Cooling Performance: What the Numbers Truly Mean

Capacity and Energy Efficiency

The DIRECT AIR HEAT XTREME PRO heat pump features:

  • Cooling Capacity: 36,000 BTU
  • Heating Power at -8°C: 33,000 BTU
  • Heating Power at -15°C: 36,000 BTU
  • SEER2: 22.3
  • HSPF2: 10.3
  • COP at -8°C: 1.93
  • Certifications: ENERGY STAR® + Cold Climate + AHRI (207743791)

This data is not merely technical: it reflects a real-world performance that we regularly observe. In several projects in Boucherville and Laval, this unit has replaced expensive electric systems, significantly reducing winter energy consumption.

According to the official brochure, the HX PRO series achieves performance levels of up to SEER 25 and HSPF 12, placing it among the high-efficiency systems available on the market.


Operation in Extreme Conditions

One of the most important aspects for our customers is heating stability in winter. This heat pump:

  • Operates efficiently down to -35°C
  • Maintains constant performance without sudden drops
  • Features an intelligent automatic defrosting system

In a recent installation in Longueuil, a customer previously had a system that practically stopped heating at -20°C. After installing this model, the indoor temperature remained stable even on the coldest days of January.


Multi-zone Configuration: Flexibility and Personalized Comfort

3 Independent Zones

This model allows connecting up to 3 indoor units (expandable to 4 zones), offering:

  • Independent control of each room
  • Reduced energy loss
  • Personalized comfort for each occupant

According to the manufacturer's combination rules, the total capacity of the indoor units must be between 66% and 133% of the outdoor unit's capacity. This rule is essential to ensure optimal performance.

Compatible Unit Types

The HEAT XTREME PRO series offers great flexibility:

  • Wall-mounted units
  • Consoles
  • 4-way ceiling cassettes
  • Ducted units
  • Ceiling/floor units

In a project in Montreal (Rosemont), we combined:

  • 2 wall-mounted units
  • 1 low-profile console

This type of configuration allows the system to be adapted to architectural constraints without compromising performance.


Smart Comfort and Advanced Features

Automatic Airflow Management

The indoor units offer:

  • Automatic vertical louvers
  • Automatic horizontal louvers
  • Louver position memory
  • Optimized air distribution

Result: homogeneous temperature distribution, without cold or overheated zones.


Integrated Technologies

The heat pump includes several advanced functions:

  • Automatic restart
  • 24-hour timer
  • Eco mode and turbo mode
  • Humidity sensor
  • Self-cleaning
  • Motion sensor
  • "Follow Me" function

These elements are not theoretical: during our HVAC maintenance in Laval, we observe that these functions genuinely help extend the lifespan of the units and improve daily comfort.


Wi-Fi and Smart Home

Wi-Fi is available as an option and is compatible with:

  • Google Home
  • Alexa
  • Home automation systems

This allows owners to control their system remotely, which is particularly useful for secondary residences or rental properties.


HVAC Installation: AirGreen's On-Site Expertise

What a Typical Installation Includes

At AirGreen, a standard installation includes:

  • Wall or ground mounts
  • Complete electrical connection
  • Refrigerant piping (up to 15 feet)
  • Full commissioning
  • Performance testing

Real-World Example: South Shore Installation

Project carried out in Saint-Hubert:

  • 2-story single-family home
  • 3 zones: living room, master bedroom, basement
  • Previous system: electric baseboards + wall-mounted air conditioner

Result after installation:

  • Uniform comfort throughout the house
  • Significant reduction in energy costs
  • Appreciated quiet operation (28 to 41 dB indoors)

Common Mistakes to Avoid

We often encounter problematic installations carried out without expertise:

  • Incorrect sizing of zones
  • Excessive piping length
  • Inadequate unit positioning

These errors drastically reduce performance. This is why a professional analysis is essential before any HVAC installation.


Noise Level and Acoustic Comfort

  • Indoor: 28 to 41 dB(A)
  • Outdoor: 63 dB(A)

In a project in Montreal (Plateau), a client was concerned about noise. After installation, the system proved quieter than their old wall-mounted air conditioner.


Reliability, Warranty, and Durability

The DIRECT AIR HEAT XTREME PRO heat pump offers:

  • Warranty: 10 years compressor / 10 years parts / 0 year labor
  • Extended warranty available
  • Manufactured to high Canadian standards

These elements ensure a secure long-term investment.


Available Subsidies in Quebec

This model is eligible for the subsidy:

  • LogisVert: up to $3,960

At AirGreen, we assist our clients with all the procedures to maximize available financial aid.
