I came down with allergy problems for the first time in my life, apparently from allergens and material that was in my ducts for over 35 years. It got so bad that I had to keep some windows open while I was running my central AC. I often felt that I didn t want to come home. But all of that ended after they finished their work. Thank God and Duct Diagnostics for that. And during the weeks after my ducts were cleaned, I ve noticed a lesser accumulation of dust on my furniture. maybe a lot of it was coming from my own ducts?
