John the Duct Man is the best service professional I have ever had in my home. He takes pride in his work, and takes time to do the job right. This is the 2nd time I have used his services. Two years ago I had my dryer duct cleaned- I was really impressed with his work. Last week we had all the ducts, air conditioners, and furnaces cleaned and serviced. I couldn't be happier! Talk about a breath of fresh air!!! Thanks again Duct Man!!!
