A custom solution for invisible yet powerful comfort
Installing a ducted HVAC system in a typical North Shore bungalow is never a routine task. At AirGreen, we are often called upon to modernize single-story homes built before the era of centralized HVAC solutions. These projects require not only in-depth knowledge of the best brands on the market but also technical expertise to tailor the installation to the home’s architectural specifics. Here’s a concrete case study showing how we transformed a modest living space into an environment with optimal thermal comfort, thanks to the installation of a high-performance central ducted system.
A well-maintained home, but poorly air-conditioned
This project involved a bungalow built in the 1970s, located in Blainville, on the North Shore of Montréal. Despite being well maintained, the house suffered from uneven thermal comfort, especially in the summer. Over the years, the owner had installed individual wall-mounted units in different rooms, but the result was far from consistent: cold zones, overheated rooms, high energy consumption, and a lack of aesthetics due to multiple visible units.
Objective: centralized and discreet comfort
The client wanted to eliminate all wall units, adopt a centralized solution, and especially minimize visual impact inside the home. Our recommendation: a ducted system, an invisible solution that enables even air distribution throughout the house via discreet grilles built into the ceilings.
Equipment choice: efficiency, silence, and compactness
After evaluating the needs, we selected a GOODMAN ducted system with R-32 refrigerant, 36,000 BTU/h model, perfectly suited for the 100 m² of livable space in the bungalow. This model is known for its energy efficiency (SEER 17, HSPF 10), reliability, and low noise level — a key factor in a quiet residential environment.
The system is fully eligible for Hydro-Québec’s LogisVert rebates, which allowed the client to benefit from a $2,058 discount on the installation.
Key installation stages: expertise and adaptation
1. Full thermal analysis
First, our team conducted a comprehensive thermal assessment of the home, taking into account room orientation, insulation, windows, and space usage. This step helped us identify the needs of each zone and accurately size the duct network.
2. Ductwork design
The biggest challenge in this type of home is the lack of ceiling space. So we designed a compact network, entirely housed in the attic, with ultra-flat ceiling diffusers, painted the same color as the ceilings for invisible integration.
3. Installation of the main system
The GOODMAN central ducted unit was installed in an accessible technical corner of the attic, on an anti-vibration base, to minimize operational noise. The ducts were insulated with R8 materials to prevent thermal loss in the unheated attic.
4. Smart thermostat and zoning
We also installed a Wi-Fi-enabled smart thermostat, with optional individual zoning, allowing for different temperatures in the bedrooms, kitchen, and living room. This feature was a top priority for the client, who wanted to reduce energy bills while optimizing comfort.
Final result: comfort, silence, aesthetics
From the very first start-up, the results were impressive: even temperature throughout the house, no perceptible noise, and the complete disappearance of wall-mounted units. The homeowner immediately noticed an improvement in indoor air quality and increased comfort, especially at night.
A clear return on investment
With an estimated 35% reduction in annual energy consumption, the client expects a return on investment in less than 6 years, not to mention the increased property value thanks to a modern, energy-efficient central HVAC system.

Every installation comes with an optional HVAC maintenance contract that includes annual follow-ups, duct cleaning, airflow checks, and thermostat adjustments.
Practical advice for bungalow owners
-
Plan a dedicated technical space in the attic or a deep closet for the central unit installation.
-
Opt for a system compatible with smart thermostats, to benefit from multi-room zoning.
-
Make sure your attic insulation is adequate, especially if the ducts run through that area.
-
Think about resale value: a centralized system can increase your property’s value and appeal to energy-conscious buyers.
Conclusion
This HVAC modernization project in Blainville is a clear example of our tailored, technical, and comfort-focused approach. Thanks to the integration of a Goodman central ducted system, this North Shore bungalow gained value, comfort, and energy efficiency, all while preserving the aesthetic integrity of its rooms.
At AirGreen, we believe every HVAC installation should be as functional as it is discreet, and above all, perfectly adapted to the realities of Québec homes.
