I had tried a DIY installation of a Third Generation Nest. There was an issue with the electric hookup of the thermostat in my house. I put in a work request for a Third Generation Nest installation for my home. Kevin from Charter Oak Mechanical was quick to respond and very helpful.
He was able to identify the issue and solution the installation of my Third Generation Nest. He was pleasant, knowledgeable and quick to complete the work request. He even assisted in the initial program setup for the Nest.
