This was an all around excellent experience, especially with 2 small kids in the house. We felt at ease with our serviceman and we were able to run errands while feeling secure there was a professional in our house. He worked 6 hours straight while having to work around a not-so-neat household and was very thorough, even closing an area in our ducts that a prior duct cleaning company had forgotten about prior to us owning the home. Thanks so much for an excellent and professional job, I have never seen such clean ducts and there was no chemical smell, just a very fresh clean feel! We are 110 satisfied!
