A faulty ventilation system can affect your comfort—but more importantly, your health. Here’s what we often see in Longueuil.
At AirGreen, we provide daily service calls in Longueuil to diagnose, repair, or install residential and commercial ventilation systems. While many people think of ventilation as a luxury or a simple comfort add-on, we know that it plays a critical role in indoor air quality—an often overlooked element that can directly impact your health, your family’s, or your employees’.
In this article, we’re revealing 3 common ventilation issues that are often ignored in Longueuil—but that can seriously harm your well-being. We’ll show you how to spot them, how to avoid them, and most importantly, how our HVAC experts handle them effectively.
1. Invisible buildup of contaminants: mold, fine dust, and VOCs
The hidden threat behind a neglected system
In many homes and businesses in Longueuil, we regularly uncover ventilation ducts that are clogged—or even infested with mold that’s invisible to the naked eye. This often results from ventilation systems that haven’t been maintained, are improperly sized, or poorly installed.
Fine dust particles, spores, bacteria, and volatile organic compounds (VOCs) build up and circulate through indoor air. These pollutants are particularly dangerous for:
-
People with asthma or allergies
-
Young children
-
Seniors or anyone with a weakened immune system
-
Employees working in closed environments
What we do at AirGreen
When we’re called for a ventilation service in Longueuil, we start with a full diagnosis: air quality analysis, duct inspection, filter condition, relative humidity, and more. We use professional-grade tools to identify contamination and offer tailored solutions: cleaning, HEPA filter replacements, decontamination, or upgrading your current system.
2. Poor air exchange: that stuffy feeling and chronic fatigue
The effect of stagnant CO₂ on your brain
One of the most frequent issues we see in Longueuil is inadequate air exchange in buildings. This often manifests as:
-
Stale or stuffy air
-
Trouble concentrating
-
End-of-day headaches
-
Ongoing fatigue
This is usually caused by an excess of trapped CO₂, especially in well-insulated homes or offices without controlled fresh air supply. Outdated or poorly configured equipment can make this worse.
Our approach to improve your comfort
Our technicians install heat recovery ventilation systems (HRVs) or energy recovery ventilation systems (ERVs). These systems:
-
Continuously refresh indoor air without heat loss
-
Regulate humidity levels to maintain a healthy balance
-
Provide customized airflow rates based on the space and occupancy
We install trusted brands like Venmar, Lifebreath, Broan, Aldes, carefully sized for optimal performance across Longueuil.
3. Excessive noise and thermal discomfort: signs of a poorly designed system
Acoustic and thermal comfort often get ignored
Some clients reach out because their ventilation system is too noisy, or it creates cold drafts in winter—or too much heat in summer. These discomforts are usually due to:
-
A system that’s not properly sized for the room’s volume
-
Improper installation (poor grille placement, misaligned ductwork)
-
Lack of room-by-room airflow regulation
These issues are more than just annoying—they often cause people to stop using their system, waste energy, and live in constant discomfort.

Case study: full residential ventilation retrofit in Longueuil
One of our recent projects involved a single-family home in the Fatima neighborhood. The homeowner suffered from chronic allergies and complained of heavy, stale air—especially in winter. Our diagnostic revealed a complete absence of mechanical ventilation, and the windows stayed shut due to the cold.
We installed a Venmar EVO5 700 HRV dual-flow ventilation system, discreetly tucked into the basement. The setup included:
-
4 extraction vents in the kitchen, bathroom, laundry room, and mechanical room
-
6 supply vents in bedrooms and living areas
-
Insulated ducts for maximum energy efficiency
-
A smart programmable control system
The result: a dramatic improvement in indoor air quality, allergy symptoms disappeared, humidity levels stabilized—and a very satisfied customer.
