We have had Dukes of Air out several times and they have always been honest, informative and thorough! This last visit was from Todd and Bray who ended up saving us a lot of money on what we thought was going to be an expensive replacement by identifying the root cause of the issue which were 2 internal parts. We had some other temperature and duct issues with specific rooms upstairs and Bray identified a solution for that at the same time. Couldn't be happier and we're a Dukes customer for life!
