Installation of a FUJITSU Aquila R32 Dual-Zone 36,000 BTU Heat Pump in Saint-Eustache

An HVAC Installation Designed to Withstand Quebec Winters in a Confined Space

In Saint-Eustache, we recently completed a particularly interesting HVAC installation featuring a FUJITSU Aquila R32 DoubleZone 36,000 BTU heat pump (model AOUH36KWAS4). This project stood out due to a challenging outdoor environment, a strategic multi-zone configuration, and meticulous attention to durability in winter conditions.

Upon arrival at the site, we observed a common challenge in homes on the North Shore: limited outdoor space, with significant proximity between walls, railings, and technical access points. In this context, every installation decision has a direct impact on equipment performance and longevity.


A Dual-Zone Configuration Perfectly Suited to the Building

Intelligent Distribution of Thermal Comfort

The chosen configuration for this residence in Saint-Eustache relies on a dual-zone heat pump, allowing for efficient air conditioning and heating of two distinct spaces. This approach offers several advantages:

  • Independent temperature control in each zone
  • Reduced energy consumption
  • Optimized comfort based on room occupancy

In this specific case, we installed:

  • An indoor unit for the main living area
  • A second unit for a floor or secondary zone requiring distinct control

This strategy is particularly relevant for family homes in Laval, Longueuil, or the South Shore, where needs vary depending on levels and room usage.


Technical Analysis of the FUJITSU Aquila R32 36,000 BTU

Energy Performance and Reliability

The installed model, AOUH36KWAS4, stands out for:

  • Cooling capacity: 36,000 BTU
  • Heating operation down to -15°C
  • R-32 refrigerant (more eco-friendly and efficient)
  • SEER2: 22.0 | HSPF2: 10.0 | EER2: 12.0
  • Outdoor sound level: 56 dB(A)

These characteristics make it a solid choice for residences in Montreal and the North Shore, where climatic variations demand reliable equipment year-round.

INVERTER Technology: Stability and Savings

Thanks to INVERTER technology, the heat pump continuously adjusts its power. The result:

  • Fewer on/off cycles
  • Reduced electricity consumption
  • Constant temperature without fluctuations

Challenges Encountered During Installation in Saint-Eustache

1. Winter Installation

As seen on the construction site, the installation was carried out with snow and ice on the ground. This implies:

  • Ground preparation to ensure a stable base
  • Drainage verification to prevent accumulation of frozen water
  • Strategic positioning to avoid being buried by snow

2. Elevated Support for Outdoor Unit

We installed the outdoor unit on an elevated metal support. This choice is crucial for:

  • Avoiding direct contact with snow
  • Protecting the equipment from freezing
  • Ensuring optimal air circulation

This is a practice we systematically recommend in cities like Terrebonne, Blainville, or Saint-Eustache, where snow accumulation is significant.

3. Management of Electrical and Refrigerant Connections

On this installation, the connections were visible on the right side of the building, which required:

  • Clean and secure cable organization
  • Protection against bad weather
  • Aesthetic integration with the existing wall

We used professional finishing techniques to ensure a result that is both functional and discreet.


Best Practices Applied by AirGreen

Vacuuming and Micron Test

As with all our installations, we performed:

  • A complete vacuum pull
  • A stable micron test

This eliminates all moisture from the system, thus preventing:

  • Microcracks
  • Loss of performance
  • Premature failures

Protection of Refrigerant Lines

The pipes were:

  • Properly insulated
  • Securely fastened
  • Protected against climatic variations

Precise Alignment and Leveling

A poorly leveled outdoor unit can lead to:

  • Excessive vibrations
  • Premature wear
  • Reduced efficiency

We therefore took the time to ensure a perfectly straight and stable installation.


Common Mistakes to Avoid During an HVAC Installation

Through our interventions in Montreal, Laval, and the South Shore, we often observe the same mistakes:

  • Installing the outdoor unit directly on the ground
  • Neglecting the vacuum pull
  • Underestimating the importance of location
  • Using supports not adapted to the Quebec climate

In this project in Saint-Eustache, every detail was considered to avoid these errors and guarantee optimal long-term performance.


Subsidies and Profitability

This FUJITSU Aquila R32 DoubleZone 36,000 BTU heat pump is eligible for a LogisVert subsidy of approximately $1,180 (according to current updates).

This allows for:

  • Reducing the initial cost
  • Improving return on investment
  • Encouraging a transition to cleaner energy

Field Feedback: A Silent and Efficient System

After commissioning, the results were immediate:

  • Silent operation despite the proximity of walls
  • Even temperature distribution
  • Quick system responsiveness

The client now enjoys stable comfort, even on typical cold days on the North Shore.
