A Montréal home embraces smart ventilation and transforms its indoor comfort
At a time when indoor air quality has become a major concern in our living spaces, smart ventilation is emerging as an essential solution. In this residential home located in the heart of Montréal, the owners called on AirGreen to completely rethink their HVAC ventilation system, with the goal of maximizing comfort, energy efficiency, and smart home connectivity.
This project shows how a well-planned installation, paired with smart ventilation technology, can radically transform the everyday life of the occupants. Here’s a detailed look at this residential ventilation intervention in Montréal, from consultation to the tangible results experienced by the homeowners.
Why this home needed smart ventilation
The house, a century-old property recently renovated, suffered from several common issues:
-
Persistent humidity in the main bathroom.
-
Stale air and lingering odors in some closed-off rooms.
-
Temperature imbalances between floors.
-
Overall discomfort, especially during summer heatwaves or the winter cold.
Despite having a central air conditioning system, the lack of effective mechanical ventilation significantly affected air quality and the residents’ well-being. After a thorough technical assessment, our AirGreen team recommended a smart ventilation solution with automated control, tailored to a connected home.
Technical details of the ventilation system installed
To meet the specific needs of this residence, we installed a combination of:
-
High-efficiency HRV air exchanger with heat recovery (capacity: 150 CFM).
-
CO2 and humidity sensors placed in key zones (bathroom, bedroom, basement).
-
Smart Wi-Fi controller compatible with existing smart home systems (Google Home and Alexa).
-
Quiet high-flow ventilation grilles with motorized dampers, for automatic airflow adjustments.
Thanks to the installation of a centralized system using insulated rigid ductwork, we ensured optimal distribution throughout the house, including the finished basement and converted attic.
A custom installation in an older building
Integrating a modern ventilation system into a home built in the 1920s comes with its share of challenges. Our technicians had to:
-
Route the ducts through load-bearing walls without damaging the structure.
-
Create discreet access points for future maintenance, while preserving the interior design.
-
Insulate all ducts according to building code standards to prevent energy losses.
-
Install the sensors in strategic locations without compromising aesthetics.
The entire project was completed in less than three working days, in close coordination with the homeowners and with minimal disruption to their daily life.
Results observed within the first 30 days
The occupants began to notice tangible benefits within the first few weeks:
-
Over 60% reduction in humidity in the bathroom.
-
Noticeable improvement in air quality, especially in the bedrooms.
-
Stabilized temperatures between the ground floor and upper levels.
-
Less lingering odors in the kitchen and basement.
-
Better energy management thanks to a ventilation system that self-adjusts based on occupancy and needs.
Data collected via the mobile app shows reduced energy consumption for the ventilation system, with shorter but more efficient operation cycles.
A system built for the future
One of the key advantages of this setup is its scalable compatibility. Thanks to the smart controller, the system can integrate with other HVAC equipment:
-
Central or wall-mounted heat pump
-
Central dehumidifier
-
HEPA air purifier
-
Radiant or heated floor system
The home is now ready for a full transition to an eco-efficient smart energy system, aligned with Montréal’s carbon footprint reduction goals.
