An invisible yet powerful solution: when performance meets discretion in Laval
In Laval, a couple living in a single-family home was facing a common but burdensome issue: skyrocketing heating bills every winter, despite regular maintenance of their old system. Dissatisfied with their thermal comfort and concerned about energy consumption, they reached out to AirGreen in search of a sustainable, discreet, and—above all—efficient solution. The result? A ducted HVAC system installation that allowed them to cut their electricity bills in half—without compromising the aesthetics of their interior.
Why choose a ducted system?
Total discretion, maximum efficiency
Unlike traditional systems like wall-mounted heat pumps or visible consoles, a ducted system is integrated into the walls or ceilings. Only discreet air vents hint at its presence. This type of solution is ideal for those seeking invisible comfort, without sacrificing performance.
Impressive energy performance
The model installed in this Laval home is a Bosch BOVA 36 ducted system with Inverter technology, running on R-32 refrigerant, known for its low environmental impact. With a capacity of 36,000 BTU, this system maintains a stable temperature throughout the house, even during Quebec’s harshest winter cold spells.
Installation steps: custom expertise from AirGreen
1. Thermal analysis and planning
Before even providing a quote, our team visited the home to carry out a comprehensive thermal analysis. The goal: calculate heat loss, understand the space layout, assess existing insulation, and design a custom duct network. This step is critical to ensure optimal performance and even airflow distribution in every room.
2. Project challenges
Like many homes in Laval, this one had finished ceilings and load-bearing walls in key areas. We had to design a duct route that navigated architectural constraints, without compromising aesthetics. This required installing compact distribution boxes and using high-performance flexible ducts to reduce pressure loss.
3. Installation of the ducted indoor unit
The indoor unit was discreetly placed in a drop ceiling in the basement, accessible for maintenance but invisible day-to-day. Air supply vents were strategically installed in the main living spaces, and optimized return vents were placed in hallways, ensuring smooth and balanced airflow circulation.
4. Connection to the outdoor unit
We connected this unit to a Bosch BOVA outdoor heat pump installed on a concrete slab, protected from the elements. With its Inverter compressor and low-temperature performance, this system runs efficiently down to -25°C, with no noticeable drop in performance.
Tangible results and satisfied customers
The couple immediately noticed a nearly 50% drop in their electricity bills compared to the previous winter. They also reported an unprecedented level of thermal comfort: no more temperature swings, no cold rooms, no overheating. Thanks to a centralized smart thermostat, they can now adjust room-by-room temperature using a mobile app.
They were also eligible for the LogisVert grant from Hydro-Québec, which reduced the cost of their HVAC system by almost $2,300. AirGreen handled all the administrative paperwork, ensuring a smooth process from start to finish.

Skipping the thermal analysis: Improper duct sizing can lead to poor performance.
-
Choosing an inexperienced contractor: This type of installation requires expertise well beyond standard wall-mounted systems.
-
Overlooking available grants: Many customers are unaware they can save thousands of dollars thanks to energy transition programs.
Practical tips for future clients
-
Schedule your installation in the off-season to benefit from the best lead times.
