What if your ventilation system was quietly making you feel happier at home?
Indoor air quality influences far more than just your breathing or thermal comfort. At AirGreen, we’ve observed a surprising phenomenon that’s still rarely discussed: a properly installed and calibrated air exchanger doesn’t just improve your sleep and health—it also boosts your daily mood. Across the South Shore, several families who recently replaced their old HRV with a more efficient model have reported positive changes in their emotional state, energy levels, and even family relationships.
Here’s what their real-life testimonials reveal—and what that means for your quality of life.
Customer testimonials: when ventilation transforms daily life
In a home in Carignan, the Tremblay family contacted AirGreen to replace a 15-year-old HRV. The system was noisy and inefficient, causing a constant feeling of stuffy air and frequent headaches among the children. We installed a Lifebreath 195 ECM, carefully calibrated to the home's square footage and equipped with a silent mode.
A few weeks later, the mother told us:
“Ever since we installed the new HRV, we sleep better, we wake up feeling fresher… but above all, we’re less irritable! Before, we argued all the time for no reason. Now, the atmosphere is much more relaxed.”
Another client in Brossard, the owner of a triplex, reported that his stress levels dropped significantly after installing a Venmar EVO5 700 HRV. The reduced background noise, fresher air, and elimination of stale odors transformed his remote work space into a peaceful retreat.
Why indoor air directly affects your mood
The link between air quality and mental balance is now confirmed by several scientific studies. A good air exchanger (HRV) plays a key role by acting on several critical factors:
-
Reducing CO₂ concentrations, which are known to cause mental fatigue and mood swings
-
Filtering fine particles and allergens, limiting chronic inflammation and focus issues
-
Stabilizing humidity levels, preventing discomfort, sinus congestion, and headaches
-
Improving sleep quality, which promotes a more stable and positive emotional state
At AirGreen, we’ve seen firsthand how even small improvements in air quality can have a noticeable impact on overall well-being, especially in family homes or shared living spaces.
Common mistakes that can affect your well-being
Many homes—even modern ones—suffer from poorly designed or neglected ventilation. Here are the frequent mistakes we’ve encountered during inspections in Longueuil, Saint-Bruno, and Sainte-Julie:
-
HRV installed without properly adjusted airflow based on the home's size and layout
-
No HEPA filters or dirty filters, leading to recirculation of pollutants
-
Improper placement of air supply vents, concentrated only in common areas
-
Lack of custom settings for daily life rhythms (night mode, remote work, pets in the home)
These issues often go unnoticed by homeowners, yet they cause a gradual but steady decline in indoor ambiance.

Case study: full transformation in Laval
A homeowner in Laval, who had been suffering from migraines and chronic fatigue for months, called on our team after suspecting her environment was the source of her symptoms. After analysis, her old air exchanger had several serious issues: clogged fans, saturated filter, and no maintenance for over five years.
We replaced it with a Venmar AVS E15 ECM, and added connected CO₂ and humidity sensors. Within just a few days, she reported a significant reduction in symptoms, and most notably, a noticeable improvement in her overall mood.
“I feel calmer, I breathe better, I’m more patient with my kids… I never would’ve thought it was the air we were breathing!”
Practical tips to improve your indoor vibe
Here are a few simple recommendations to complement a high-performance HRV:
-
Air out your home briefly morning and evening, even in winter
-
Avoid air fresheners and chemical-based deodorizers
-
Replace or clean your filters every 3 to 6 months
-
Schedule annual HVAC maintenance with a qualified professional
-
Invest in a hygrometer and a CO₂ detector to monitor your environment over time
These small steps, combined with a well-designed HVAC installation, can radically improve your quality of life.
