Rudolpho showed up on time and spent most of day out here working (almost 9 hours). We were showed many before and after pictures, what a difference! We live very close to the burn area from the Waldo Canyon Fire. As luck would have it, my neighbor had a different duct cleaning service at her house on the same day. They were less expensive, but in and out in less then two hours. Her house is twice the size of mine. Needless to say, she asked who I was using and planned on calling them in the future. By the way, dust is considerably less. THANKS!!!
