I had my ducts cleaned by Wil through this company. He did a great job and was in and out in a flash. He kept me informed about what he would do and how he was going to do it. Joe the owner with whom I set up the appointment was very friendly and accommodating with my schedule. It's hard to guage the cleanliness of the air other then to say that it smells clean and the ducts are free of the dust/debris that used to be there. Thanks for the great service guys!
