Bob Miller and his employees are top notch, very professional, and go the extra mile for their customers. I have been using him for over 5 years and have never had an issue. I would give them 100 stars if I could.Services: HVAC system maintenance

We have the heat go out on a rental property on Christmas Eve. Out of the 20 companies in Knoxville that I call Duo-Tech answered the call. They were responsive, honest, and dependable. I highly recommend them. You won't find better in town
