Improving Indoor Air Quality in London Ontario Homes – 2026 Solutions
Breathe cleaner, healthier air year-round – expert guide by Abdullah Ghzail
Book Your IAQ Assessment TodayIndoor air quality (IAQ) in London, Ontario homes is more important than ever in 2026. With tight modern construction, pollen-heavy springs, humid summers, and dry forced-air heating in winter, many families deal with dust, allergens, mold risk, and stale air. Poor IAQ can trigger allergies, asthma, fatigue, and long-term health issues — especially for kids and seniors. As owner and lead TSSA-certified technician at Hawana HVAC Solutions, I help homeowners fix these problems every week. Here’s your complete 2026 guide to improving IAQ in Southwestern Ontario homes.
Why Indoor Air Quality Matters in London Ontario
- Ontario homes spend 90% of time indoors — air can be 2–5× more polluted than outside
- Winter dryness (20–30% humidity) causes dry skin, nosebleeds, and virus spread
- Summer humidity (60%+) breeds dust mites, mold, and allergens
- Pollen, pet dander, VOCs from furniture/paint, and wildfire smoke from Western Canada affect us

Brings fresh outdoor air in while removing stale indoor air. HRV recovers heat; ERV recovers heat + moisture (best for Ontario’s humid summers).
