Breathe Better at Home Thanks to Proven Professional Advice on Residential Ventilation
At AirGreen, we understand that indoor air quality is a key factor for your health, comfort, and well-being. A well-designed residential ventilation system not only eliminates humidity, odors, and pollutants, but also ensures a continuous supply of fresh air. Whether you live in Montréal, Laval, Longueuil, on the North Shore or the South Shore, these 10 expert tips will help you improve the air quality in your home.
Why Is Good Ventilation Essential in a Home?
Indoor air can sometimes be up to five times more polluted than outdoor air, due to household cleaners, building materials, cooking fumes, and trapped humidity. Poor ventilation can lead to:
-
Mold growth
-
Lingering odors
-
Allergies or respiratory issues
-
Premature deterioration of your home
Our residential HVAC experts work daily throughout the Greater Montréal area to provide high-performance, long-lasting ventilation solutions tailored to each home.
1. Invest in a Certified, High-Performance Air Exchanger
Installing an air exchanger (such as a Venmar EVO5 or Lifebreath RNC model) helps remove stale air and bring in fresh air while minimizing heat loss. These systems are built to operate continuously and are ideal for well-insulated homes.
AirGreen regularly installs this type of system in modern homes in Laval and in renovated older homes in Montréal, with impressive results on ambient air quality.
2. Make Sure Your System Is Properly Balanced
Even the best ventilation system must be properly balanced to function optimally. This means that the amount of air coming in and going out must be equal. An imbalance can cause negative pressure, draw in humidity, or affect thermal comfort.
Our technicians use precision measurement tools to adjust each system during installation, especially in intergenerational homes in Longueuil and new builds on the North Shore.
3. Clean Filters and Ducts Regularly
Clogged filters or obstructed ducts reduce your system’s efficiency and may spread contaminants throughout the house. We recommend:
-
Replacing or cleaning filters every 3 months
-
A full duct cleaning every 3 to 5 years
AirGreen offers a complete HVAC maintenance service in all serviced regions, including indoor air quality diagnostics.
4. Control Humidity Accurately
An ideal indoor relative humidity is between 30% and 50%. Too low, it dries out mucous membranes; too high, it encourages mold growth.
Our experts can integrate humidifiers or dehumidifiers directly into your ventilation system for precise, automated control, as we've done in several family homes in Boucherville and Terrebonne.
5. Integrate a Heat Recovery Ventilation System (HRV)
A Heat Recovery Ventilator (HRV) is a smart solution to improve energy efficiency while ventilating effectively. It allows you to recover heat from outgoing air to warm incoming air without sacrificing air quality.
We’ve installed many high-performance HRVs in single-family homes in Saint-Lambert and condos in Laval, with excellent feedback from clients regarding comfort and energy savings.
6. Don’t Rely Solely on Opening Windows for Ventilation (This One Will Surprise You!)
Contrary to popular belief, opening windows is not enough to properly ventilate a house—especially in winter. It causes massive heat loss without truly refreshing the air in a controlled way. A mechanical ventilation system ensures constant, measured, filtered air exchange.
7. Add HEPA or Activated Carbon Filtration If Needed
If you or someone in your household suffers from allergies, asthma, or sensitivity to pollutants, advanced air filtration is essential. HEPA or activated carbon filters can trap:
-
Pollen
-
Fine particles (PM2.5)
-
Volatile Organic Compounds (VOCs)
We’ve implemented these solutions in homes in Saint-Eustache and Verdun, where residents saw a clear improvement in respiratory comfort.
8. Automate Your Ventilation with Smart Sensors
Some of the latest systems allow you to automatically adjust ventilation based on humidity, CO₂ levels, or room occupancy. This maximizes efficiency while ensuring consistent air quality.
We recently equipped a new home in Candiac with a Venmar AI system that adapts in real-time to household activity, reducing energy use by 18%.
9. Properly Ventilate High-Moisture Areas (Kitchen, Bathroom, Basement)
These areas generate the most humidity and pollutants. Make sure that:
-
The kitchen range hood is vented outside
-
Bathroom fans are strong and used regularly
-
The basement has an exhaust system or mini air exchanger
10. Have Your System Professionally Inspected at Least Once a Year
Even a well-designed system can degrade over time. An annual HVAC inspection allows you to:
-
Detect hidden issues
-
Optimize performance
-
Prevent costly breakdowns
AirGreen offers customized maintenance contracts with priority service and automatic reminders. Many loyal clients in Boisbriand, Brossard, and Ahuntsic enjoy this peace of mind.
