Great installation of a great generator, followed with good verbal instructions on the operation and features at the end of the project. I am very comfortable with the quality of workmanship, the personability of the employees, and their efforts to minimize any messes the job may create, especially if inside the house. I use Black Diamond now for all my electrical, plumbing, and HVAC needs. They may be a little pricey, but they are worth it, and they get to my projects very quickly with no long waits, so they are very convenient.
