True Stories: These Montréal Residents Saw Their Health Transformed by a Simple Air Exchanger

In Montréal, the right air exchanger can change your life – proven through real testimonials

At AirGreen, we know that indoor air quality goes far beyond comfort. It directly impacts health, concentration, sleep, and even mood. Across various areas of Montréal, Laval, Longueuil, the North Shore, and the South Shore, we’ve witnessed incredible transformations in families and professionals after installing a high-performance air exchanger. In this article, we share true stories, directly from the field, that reveal the often underestimated impact of a good HVAC ventilation system on health and well-being.

The invisible problems caused by poorly renewed air in Montréal

Allergies, migraines, chronic fatigue: symptoms often tied to poor ventilation

In Rosemont, a family of four was struggling with persistent allergies and frequent headaches, especially during winter. Their central heating filters were changed regularly, but nothing seemed to help. After our intervention, we discovered an old HRV system, poorly balanced, that wasn’t properly renewing stale indoor air. We replaced it with an Aldes InspirAIR Top 300, equipped with high-efficiency MERV 13 filters.

The result: symptoms practically disappeared within two weeks, and air quality levels were measured to be in line with hospital-grade standards.

Children with asthma and stagnant air: an all-too-common scenario

In a Longueuil home, parents of a child with asthma contacted us after several nighttime attacks. Their house, though well insulated, lacked proper air exchange. We installed a Venmar AVS S10 ERV, specially designed for cold climates, with energy recovery and controlled humidity.

Since then, asthma attacks have significantly decreased. The parents report fresher, more stable air with no humidity spikes – offering their child a new level of respiratory comfort.

Testimonial from a professional in Laval

Marc-Antoine, a graphic designer in Laval, had been working from a converted basement office for three years. He experienced afternoon drowsiness and frequent sore throats. He had tried air purifiers, but they didn’t offer lasting results. Upon inspection, we found extremely high CO₂ levels in his workspace.

We recommended a Fantech FLEX 100H air exchanger, perfectly suited for smaller spaces. The unit was discreetly installed in his office, with strategically placed intake and exhaust vents. In less than a week, Marc-Antoine reported improved energy levels, better focus, and complete relief from his symptoms.

Real case from the North Shore: a transformed daycare

A home-based daycare in Blainville received regular complaints from parents about children constantly catching colds during the winter. Our team was called in for an evaluation. The indoor air had 72% humidity, unstable temperature, and inadequate ventilation.

We installed a complete HVAC ventilation system including a Venmar N Series air exchanger, humidity control, and well-distributed vents in every room. In less than a month, the director reported a dramatic drop in sick days and a noticeably healthier atmosphere for both children and staff.

Technical aspects of the units installed by AirGreen

We select our air exchangers based on strict criteria:

• ENERGY STAR certification required

• High heat or energy recovery efficiency, above 75%

• Compatibility with LogisVert or Novoclimat subsidy programs

• High-efficiency ECM motors

• High-density filters (MERV 13 or higher) to remove allergens, dust, pollutants

All our systems are sized precisely based on living area, occupancy, and layout.

What a typical installation looks like with AirGreen

1. On-site evaluation: measuring humidity, CO₂ levels, airflow, and temperature

2. Customized equipment selection: based on real needs of the space

3. Installation by certified technicians: with full system balancing and setup

4. Post-installation inspection: to verify comfort, noise levels, and performance

5. Client follow-up and maintenance tips: to maintain long-term efficiency

What these stories have in common: cleaner air, better lives

Our clients in Montréal, Laval, Longueuil, the North Shore, and the South Shore trust us with their well-being – and we respond with expertise, transparency, and results.

Mistakes to avoid that can harm your health

• Neglecting to balance the system: creates negative pressure or lack of fresh air

• Installing an undersized exchanger: ineffective in large or multi-storey homes

• Neglecting filter maintenance: leads to bacterial contamination and motor overload

• Installing the unit too close to bedrooms without proper soundproofing
