Ava Heartwell

I’m Ava Hartwell, and I created IndoorAirInsights.com after surviving something I never imagined could happen in a brand-new, “dream” custom home. Hidden leaks, poor construction, and months of mysterious symptoms I couldn’t explain eventually revealed the truth: my house was making me sick. What followed was a long, messy, emotional fight to understand mold, environmental toxins, and what it takes to reclaim your health when your own home becomes unsafe. Today, I write to help you avoid what I went through—or navigate it with far more clarity than I ever had. My work blends lived experience, research, practical guidance, and the raw honesty I wish someone had given me in the beginning. Whether you’re dealing with mold, unexplained symptoms, or just trying to create a healthier home for your family, you’re not alone here. I’ve walked this road, and I’m determined to make it easier for the next person who has to.
