I'm extremely picky and familiar with the kind of work they do so I can find things to harp on, however they did everything at a high level regardless (minus 1 star for my pickiness). I asked them to move a duct and they were very responsive and cooperative. I would recommend them to manage your HVAC solution. What I liked the most though is that I felt valued to them. They did a good job on managing the relationship and that's most important to me.
