Dust accumulating on furniture in just a few days, allergies worsening, and a feeling of stuffy air despite frequent cleaning... This is the daily reality for many households in Montréal, Laval, Longueuil, as well as the North Shore and South Shore. At AirGreen, we often meet customers frustrated by the excessive dust in their homes, not realizing that their ventilation system is often the root cause — or their best solution.
An Overlooked Truth: Dust is Primarily a Ventilation Issue
In the collective imagination, dust mostly comes from the outside. However, a large portion of this dust is produced inside the home itself: dead skin cells, textile fibers, dust mites, pet hair, cooking particles, etc. Without an effective ventilation system, these particles stagnate, circulate without being filtered, and end up on your floors, furniture, and in your airways.
The Importance of an Air Exchanger in Fighting Dust
An air exchanger, when installed and properly calibrated, plays a key role in the continuous renewal of indoor air. At AirGreen, we primarily install high-performance models from well-known brands such as Venmar, Aldes, Lifebreath, and Fantech, always tailored to the home’s configuration and its occupants' needs.
Here’s how these systems contribute to a cleaner, healthier home:
-
Filtering fine particles: Integrated filters capture dust before it accumulates.
-
Balancing humidity: Proper humidity levels reduce the proliferation of dust mites, which are often dust allergens.
-
Reducing contaminants: Fresh outdoor air is filtered, and dust-laden stale air is expelled.
Case Study: Air Exchanger Installation in Longueuil in a Century-Old Home
We were recently called by a family living in a home built in 1925 in Longueuil. Despite their thorough cleaning, dust kept reappearing. AirGreen’s experts quickly diagnosed the issue: the house had no mechanical ventilation, and the stagnant air was promoting the accumulation of dust, mold, and odors.
Our Intervention:
-
Installation of a Venmar EVO5 500 HRV air exchanger, a high-efficiency model suited for older homes.
-
Discreet work: minimal wall drilling, ducts concealed in the attic.
-
Integration of a MERV 13 filter, ideal for capturing the finest particles.
Result:
Within the first week, the homeowners noticed a visible reduction in dust and a significant improvement in air quality. The allergy-prone children slept without nasal congestion for the first time in months.
Why Choosing the Right Device is Critical
Not all air exchangers are the same. At AirGreen, we perform a complete analysis of the required airflow, the home’s layout, seasonal needs, and local ventilation standards in Montréal, Laval, Longueuil, North Shore, and South Shore. We prefer devices that are:
-
ENERGY STAR certified.
-
Equipped with smart sensors for humidity and CO₂.
-
Suitable for Novoclimat standards or government rebates like LogisVert from Hydro-Québec.
HVAC Maintenance: A Frequently Overlooked Yet Essential Factor
A poorly maintained air exchanger can itself become a source of dust. We recommend:
-
Cleaning filters every 3 months.
-
Annual inspections by AirGreen, including the ducts, heat recovery core, and motors.
In 2024, we assisted over 500 households in the greater Montreal area with air exchanger installation or maintenance. The common factor? All of them reported that dust reduction was one of the most noticeable benefits.
Dust, Allergies, Humidity: A Vicious Cycle You Can Avoid
Dust is not just an aesthetic nuisance: it is often the cause of chronic allergies, respiratory issues, premature furniture degradation, and mold if humidity is poorly managed. A good ventilation system breaks this cycle by:
-
Eliminating pollutants.
-
Controlling humidity levels.
-
Boosting the home’s energy efficiency.
