A custom HVAC installation project in Laval: efficiency, discretion, and total comfort
In the HVAC field in Laval, every project represents a new challenge and a new opportunity to showcase our expertise. At AirGreen, we understand that our residential and commercial clients expect far more than just thermal comfort—they want energy efficiency, visual discretion, and above all, long-term reliability. In this article, we take you behind the scenes of a project we completed in Laval, where we installed a custom ducted system perfectly integrated into the building’s layout.
An invisible solution for all-around comfort
Ducted systems—often called "invisible centralized systems"—are increasingly popular among homeowners in Laval and beyond for their elegant integration into interior architecture. Unlike a wall-mounted air conditioner or mini split heat pump, the ducted unit is completely hidden in the ceiling or attic, with only discreet vents visible. This allows for even air distribution, without compromising the aesthetic of the space.
Technical details of the installation: brand, power, and configuration
For this project, we installed a FUJITSU AIRSTAGE R-32 central ducted heat pump, model ARXG36KMTB, paired with an outdoor unit AOUA36KBTB. This setup, with a capacity of 36,000 BTU, is perfectly suited for a large single-family home in Laval, spread over two floors with a basement.
This Fujitsu model runs on R-32 refrigerant, known for its low environmental impact (lower GWP than R-410A) and excellent energy efficiency. It is ENERGY STAR certified, making it eligible for generous government grants under the Hydro-Québec LogisVert program, including a rebate of up to $2,510, depending on the system’s layout and the home’s surface area.
Project stages: precision work
1. Thermal analysis and duct network design
Before installation, our technicians conducted a complete thermal analysis of the home: orientation, insulation, volume of air to treat by zone. Based on this data, our engineering team designed a custom duct layout, with independent zones for each floor, ensuring precise control and optimal comfort room by room.
2. Ceiling work and duct installation
The indoor unit was installed in a basement drop ceiling, near the mechanical room, for easy maintenance. We used insulated flexible ducts to minimize heat loss and reduce airflow noise. Supply and return grilles were discreetly integrated into the ceilings of both living and sleeping areas.
3. Electrical integration and zoned thermostats
Each zone was equipped with a digital wall-mounted thermostat, allowing the family to adjust the temperature based on actual needs. The Fujitsu outdoor unit, installed on a raised concrete pad at the back of the property, was connected using refrigerant lines carefully concealed along the back wall.
4. Commissioning and verification
After completing the installation, our team carried out a thorough inspection of every parameter: gas pressure, airflow at each vent, temperature balance, and thermostat calibration. A full report was provided to the client, along with maintenance recommendations.
Client testimonial: comfort without compromise
The owner of this recently renovated home in Laval shared his satisfaction:
“We were looking for a cooling system that wouldn’t ruin the design of our home. AirGreen came through with an invisible solution that’s incredibly efficient. The team was attentive from start to finish, and we can already feel the difference.”
Why choose a ducted system for your home in Laval?
The benefits of ducted systems are numerous:
-
Total discretion: no visible wall units.
-
Silent operation: compressor outside and soundproofed indoor unit.
-
Even air distribution: each room gets the right amount of air.
-
Zoned control: precise adjustment for every area.
-
Increased property value: hidden systems enhance the appeal of the home.
Specific challenges of this project
As often is the case in Laval, some homes come with structural constraints involving ceiling space or available utility room. Here, our challenge was to minimize the impact on the basement drop ceiling while maintaining optimal performance. We adapted duct sizes and enhanced sound insulation to eliminate noise issues.
