July 14, 2022
I've worked with HVAC contractors for a living and while I was surprised at the age of the installers when they arrived, I knew they were representing a company I've also worked with for decades, albeit under a different name, General. I was not surprised at the level of experience and expertise they showed during their work. I would hire them and Hooper again and recommend Hooper to a friend.
