Car Pollution in Laval: Is Your Home Ventilation Really Protecting Your Health?

Understanding the Stakes of Residential Ventilation in Urban Laval Pollution

In Laval, as in many suburbs near Montréal, the density of car traffic has a direct impact on the air we breathe outside… and inside our homes. What many people don’t realize is that home ventilation plays a key role in protecting our health against these invisible pollutants.

At AirGreen, we’ve observed that the majority of homes in Laval—especially those located near major roads like Highway 440 or the 15—suffer from serious gaps in their controlled mechanical ventilation (CMV). Without a well-designed and properly maintained HVAC ventilation system, residents are exposed daily to fine particles, nitrogen dioxide, and volatile organic compounds (VOCs) that seep indoors.

The Invisible Dangers of Car Pollution for Laval Homes

What Particles Are Entering Your Home?

Gasoline and diesel vehicles emit large amounts of microscopic pollutants. Among them:

• PM2.5 (fine particles): small enough to slip through basic filters and reach deep into your lungs.

• Nitrogen dioxide (NO₂): linked to respiratory irritation and an increase in asthma attacks.

• VOCs: found in exhaust fumes and harmful over the long term.

Without a high-performance ventilation system, these pollutants enter and accumulate inside homes, reducing air quality and posing serious risks to children, seniors, and anyone with respiratory issues.

Real Case: Upgrading a Ventilation System in Laval-sur-le-Lac

Last March, we were contacted by a family living near the railway in Laval-sur-le-Lac. They reported frequent headaches and a heavy indoor air quality. Our team conducted a full assessment of their ventilation system, revealing that their heat recovery ventilator (HRV) was over 15 years old and no longer met standards.

We replaced their old unit with a VENMAR EVO5 700 HRV unit, equipped with high-efficiency MERV-13 filters and an automatic humidity control. In just a few days, the air quality improved dramatically, and the symptoms disappeared.

What Solutions Does AirGreen Offer for Homes in Laval?

Dual-Flow Ventilation with Advanced Filtration

We recommend dual-flow systems, especially from trusted brands like Venmar, Lifebreath, and Aldes, which provide:

• Efficient heat recovery

• Effective filtration of outdoor pollutants

• Even distribution of clean air throughout the home

Filter Maintenance and Replacement: A Vital Service

Even the best system loses efficiency without regular maintenance. At AirGreen, we offer annual service packages that include:

• Full system cleaning

• Replacement of HEPA or MERV filters

• Inspection of ductwork and humidity levels

Integration with Heat Pumps: Comfort Meets Efficiency

One of the key benefits of integrated HVAC systems is their compatibility with wall-mounted or central heat pumps. This enables:

• Better air circulation

• Consistent, comfortable temperatures

• Significant energy savings

Common Mistakes to Avoid

• Neglecting filters: a clogged filter can worsen your air quality.

• DIY HRV installation without proper balancing: poor calibration can create depressurization and draw in more pollutants.

• Ignoring home orientation: an improperly placed air intake can pull in exhaust fumes from parked vehicles.
