I have been a customer of AC Doctors for years. I called yesterday regarding an odd noise coming from the attic thinking it could be duct work related. They were able to schedule me right away. Geraldo came out and was friendly as well as very professional. He did a thorough job going over every inch of the system in our attic. He helped in making the system more effective by straightening some of the kinks in some of the tubing. He also let us know that a few areas were starting to separate and that he would get us a quote to repair them. They have an excellent yearly maintenance program that I have always used. It is a great deal for the money. AC Doctor comes highly recommended by me.
