Transformed into a true haven of peace, this basement in Laval had everything going for it after the expert intervention of our AirGreen team. This project, which perfectly demonstrates the direct impact of a well-chosen and properly installed air exchanger, illustrates how we transform problematic areas into pleasant, healthy living spaces — without compromise.
A common issue: a damp, poorly ventilated, and uncomfortable basement
In this single-family home in Laval, the homeowners were facing an increasingly troubling issue: their newly renovated basement was suffering from persistent humidity, unpleasant odours, and poor air quality. Despite adding a dehumidifier, the results were unimpressive.
This kind of situation is common in many homes on the North Shore: stagnant, damp air can lead to mold growth, damage construction materials, and even impact the occupants' health. As specialists in residential ventilation, we were called in to assess the situation and propose a durable, energy-efficient, and effective HVAC solution.
AirGreen’s assessment: inadequate ventilation that needed immediate correction
From our first inspection, we confirmed that the basement air was trapped, with no fresh air intake or proper renewal. The existing ventilation system — a simple portable fan — was not enough to ensure healthy, consistent air quality.
We therefore recommended installing a high-efficiency HRV (Heat Recovery Ventilator) specifically suited to the basement layout. This type of unit extracts stale air (loaded with moisture, odours, and pollutants) while bringing in filtered, tempered outside air.
Our solution: a Venmar AVS N Series air exchanger, custom installed
After a thorough analysis of the thermal needs, air volume, and ductwork configuration, we chose the Venmar AVS N Series 120 CFM with heat recovery, a model perfectly suited to mid-sized homes.
Technical specifications of the installed Venmar AVS N Series:
-
Airflow capacity: 120 CFM (cubic feet per minute)
-
Type: HRV (Heat Recovery Ventilator)
-
Heat recovery efficiency: up to 75%
-
Integrated MERV 8 filtration
-
Smart home compatible
-
Quiet and energy-efficient (ENERGY STAR® certified)
The unit was installed with insulated rigid ductwork, ensuring optimal performance even during the harsh Quebec winters. We chose a centralized layout, with intake and exhaust grilles strategically placed in different areas of the basement (family room, guest bedroom, bathroom).
Installation process: precision, efficiency, and cleanliness
The installation was completed in a single full day, without disrupting the daily routine of the occupants. Our two specialized technicians began by creating the necessary openings in the foundation for the air intake and exhaust, strictly following sealing and insulation standards.
Next, the unit was mounted in a designated mechanical space, with special attention given to soundproofing the housing. We also installed an electronic wall control, allowing the homeowners to adjust airflow rates, ventilation cycles, and heat recovery modes according to their needs.
Immediate results: fresh, dry, filtered, and pleasant air
Within just a few days of installation, the homeowners noticed a significant reduction in humidity, a complete disappearance of odours, and an overall increase in comfort. The air quality was noticeably improved, allowing even a family member with allergies to spend time in the basement without respiratory discomfort.
This project is a strong reminder of how proper ventilation is essential to comfort, health, and the durability of homes.
