An optimized ventilation system to improve comfort and air quality in Longueuil
At AirGreen, our expertise in installing intelligent ventilation systems is demonstrated through concrete projects tailored to the specific needs of families across the South Shore. Today, we take you to Longueuil, where we recently installed a centralized smart ventilation system in a single-family home, providing its occupants with a durable, connected, and energy-efficient solution.
This project highlights our know-how in the HVAC field and our commitment to personalized service. In this particular case, the clients' needs went far beyond simple air circulation: they were looking for a system that could improve indoor air quality, reduce humidity, operate quietly, and be controlled remotely. Here's how we delivered on that request.
A unique smart ventilation project: context and objectives
Our clients, a family of four living in a quiet residential neighborhood in Longueuil, contacted AirGreen after experiencing recurring issues: excessive humidity in the basement, lingering odors in certain rooms, and an overall feeling of stale air. In addition, their outdated mechanical ventilation system no longer met energy efficiency standards or modern comfort expectations.
They wanted to install a smart ventilation system with a heat recovery air exchanger, capable of ensuring optimal air renewal, filtering pollutants, automatically managing airflow based on room occupancy, and integrating with their existing smart home system.
The AirGreen solution: a centralized, intelligent, and connected ventilation system
Equipment selection
After a detailed assessment of the home’s layout (square footage, number of rooms, insulation, orientation), we recommended the installation of a central ventilation system with a heat recovery ventilator (ERV), model Venmar AVS Nox 160 ECM. This model proved to be a perfect fit for their 2,400 sq. ft. home.
Key features of the installed system:
-
Model: Venmar AVS Nox 160 ECM
-
Type: Air exchanger with heat recovery (ERV)
-
Capacity: 160 CFM (cubic feet per minute)
-
High-efficiency ECM motor
-
Smart control via mobile app and voice assistants
-
MERV 13 filters for pollen, spores, and fine dust
-
Automatic variable airflow based on humidity and human presence
-
Compatible with existing home automation system (Z-Wave)
The installation process in Longueuil
Preparation and technical evaluation
The installation began with a full inspection of the existing ductwork and ventilation network. The old HRV (heat recovery ventilator) was located in a cramped, poorly ventilated area, which limited its performance. We proposed relocating it to the basement mechanical room for better accessibility and optimized airflow.
Technical installation and system startup
The installation was carried out over two days:
-
Day 1: Removal of the old system, adaptation of the ductwork, installation of new insulated flexible ducts to prevent thermal loss, and the addition of extra intake grilles in enclosed spaces (bedrooms, bathroom).
-
Day 2: Mounting the Venmar ERV, electrical wiring, integration with the smart home system, system calibration, airflow and noise testing, and occupant training on how to use the mobile app.
Everything was completed without major disruption to the occupants. We complied with all Quebec Construction Code standards for mechanical ventilation.
Results observed and client testimonial
After a few weeks of use, the family shared the initial results they observed:
-
Improved air quality: significant reduction in odors, fresher air in the bedrooms.
-
Controlled humidity: humidity levels remained stable at 40–45% even after showers and cooking.
-
Silent operation: unlike their previous system, the new unit is virtually silent.
-
Satisfaction with smart control: the smartphone control is intuitive, and the automatic scenarios (increased ventilation during cooking or at night) make daily life easier.
“We’ve rediscovered our home since the installation. The air feels lighter, more pleasant to breathe. And knowing that everything is handled automatically is a real relief.” – Mr. and Mrs. D., Longueuil
