My son has severe allergies, and we've worked hard to make our home a safe place free of allergens where he can breathe freely. So, when he began having allergy attacks at home, we were really worried. We thought we'd done everything, including installing high quality filters and using air purifiers, but the allergy attacks continued.
Eventually, an HVAC contractor suggested that we have our ducts cleaned. I was ready to try anything, so we agreed. It made a huge difference! All the dust and particles that had accumulated in the ductwork was responsible for the allergy attacks. Now that I know, I'll make sure that we have the ducts cleaned regularly so that my child can continue to breathe easily at home.
