A well-designed ventilation system does more than just bring in fresh air — it plays a critical role in reducing allergens, especially in cities like Laval, where fluctuating weather, urban pollution, and abundant vegetation lead to significant allergy spikes in spring and fall. At AirGreen, we often work with families whose quality of life is impacted by allergies, and we implement custom HVAC ventilation solutions to help transform their day-to-day comfort.
Here are 5 practical tips, based on our real-life field experience in Laval, to improve indoor air quality and better protect your family from allergens.
The right ventilation system: your main weapon against allergens
Constant renewal of indoor air is your first line of defense against allergens. Unlike simply opening windows, a mechanical ventilation system (HRV/ERV) filters incoming air, expels stale air, and prevents outdoor allergens like pollen and dust from entering your home.
At AirGreen, we install central ventilation systems with heat recovery ventilators (HRV) that not only deliver a steady flow of fresh air but also ensure optimal energy recovery, making them an eco-friendly and comfortable choice — especially in the residential neighborhoods of Laval.
Tip 1: Install an air exchanger with HEPA filters
Allergy-prone families benefit immensely from installing a high-performance air exchanger equipped with HEPA filters. These filters capture 99.97% of fine particles, including mold spores, pet dander, and pollen.
Real installation example by AirGreen in Laval
In a bungalow in Chomedey, a family dealing with chronic allergies reached out to us. We installed a Venmar EVO5 700 HRV air exchanger with hospital-grade HEPA filters. The result: a noticeable drop in allergy symptoms in the children within just two weeks.
Tip 2: Regularly maintain your ventilation ducts
Even the best system loses efficiency if it's not regularly maintained. In Laval, it's common for dust, mold, and mites to accumulate in ducts — especially in older buildings found in areas like Pont-Viau or Laval-des-Rapides.
At AirGreen, we offer a full ventilation duct cleaning and disinfection service, recommended every 3 to 5 years. This service helps prevent allergens from recirculating and extends the life of your equipment.
Tip 3: Use a properly calibrated central humidifier
Low humidity levels dry out mucous membranes and worsen allergy symptoms, while too much humidity encourages mold growth. The ideal humidity range is between 35% and 50%.
We install Honeywell and GeneralAire central humidifiers that connect directly to your HVAC system in Laval. These units automatically adjust indoor humidity based on outdoor conditions, ensuring optimal comfort year-round.
Tip 4: Avoid noisy or poorly calibrated ventilation systems
A noisy or poorly adjusted system can create uncomfortable drafts and fail to distribute air evenly throughout the home. This leads to stagnant zones where allergens can build up.
At AirGreen, we perform a complete airflow analysis for every room and offer quiet ventilation solutions, such as variable air volume (VAV) systems. These are especially appreciated by families in quiet residential areas like Laval-sur-le-Lac or Sainte-Dorothée, where people want performance and discretion.
Tip 5: Choose a ventilation system integrated with a central heat pump
A well-integrated central heat pump paired with a smart ventilation system ensures not just consistent thermal comfort, but also continuous air filtration throughout the year.
Hybrid installation example in Laval
In a home in Fabreville, we recently installed a 36,000 BTU Bosch BOVA central heat pump, connected to an optimized ventilation system with HRV and MERV 13 filters. In addition to reducing energy costs, this setup significantly improved indoor air quality and helped the family reduce the use of antihistamines.
Common mistakes to avoid for effective allergy-fighting ventilation
-
Skipping annual maintenance of your system.
-
Using low-quality filters (below MERV 11).
-
Installing systems that are oversized or undersized, and not suited to the home.
-
Ignoring high-humidity areas like basements, where mold can silently develop.
