The importance of ventilation in Longueuil condominiums
Longueuil is experiencing rapid residential growth, with many modern and complex condominium buildings emerging. Yet behind these well-maintained facades, an invisible threat often compromises occupant comfort: inadequate or faulty ventilation. At AirGreen, we’ve been called on numerous occasions to service buildings in Longueuil where recurring air quality issues, excessive humidity, or even mold were directly tied to a lack of inspection and maintenance of the central ventilation system.
In this type of shared environment, where multiple units coexist in one building, the ventilation system becomes a critical component in ensuring healthy air for all residents. And yet, very few condo boards integrate mandatory annual inspections into their maintenance plans. This poses significant health, financial, and legal risks.
The consequences of neglected ventilation in residential buildings
1. Buildup of pollutants and degraded air quality
Without regular maintenance, ducts accumulate debris, air exchangers lose efficiency, and indoor air becomes saturated with particles, dust, pollen, and even mold. In several Longueuil cases we’ve handled, humidity levels exceeded 65%, creating a perfect breeding ground for allergens and fungi.
2. Mold growth inside ducts
We were recently called to a condo near Michel-Chartrand Park. A persistent odor had been bothering residents for months. Our inspection uncovered significant fungal growth in the ductwork, due to a non-functional air exchanger that hadn’t been serviced since it was installed—over eight years ago.
3. Avoidable mechanical failures
A faulty fan, a stuck damper, a non-functioning humidity sensor—these are simple failures that could have been prevented with yearly inspections. When ignored, these minor issues lead to costly repairs or full equipment replacement.
Why an annual inspection is not just logical, but essential
A minimum standard of vigilance in Longueuil
While municipal regulations don’t (yet) mandate annual HVAC ventilation inspections, the CAN/CSA F326 standard clearly recommends yearly preventive maintenance to ensure optimal system performance. At AirGreen, we firmly believe that every condo in Longueuil should adopt this frequency as an internal requirement.
A smart investment for condo boards
Instead of facing unexpected bills of several thousand dollars for air exchanger replacement or full duct decontamination, a proactive annual inspection—at a modest cost—offers:
-
Extended lifespan for HVAC equipment
-
Prevention of disputes between co-owners
-
Optimization of energy efficiency for ventilation
-
Preservation of the building’s real estate value

Real example: successful intervention in a Longueuil condo
Last January, a condominium on Saint-Georges Street hired AirGreen for a complete annual inspection of their central ventilation system. Our findings included three partially obstructed ducts, a misbalanced air exchanger, and filters that hadn’t been replaced since 2019. Thanks to our swift intervention, residents noticed an immediate improvement in air quality and a significant reduction in humidity-related complaints.
