My home was built in 78 and with the previous owner smoking in the house it made me sick every time the air kicked on. I did some research on the cost of duct cleaning and what it entails, I found John on here with stellar reviews so I gave him a call. John is not just ethical and honest but, just a good person. Johns great attitude was constant in the 10 hours it took to clean both my systems, and the best part the smell is gone.
My wife liked John as well as he explained everything he was doing with out hesitation. I would most definitely recommend John the duct man to anyone.
