Just want to thank you for sending David and Simon out for wiring and ceiling fan installation. They were the best – explained, asked for our input, etc. Real professionals. And very customer focused. Again, thank you!

Terry W.

I am very pleased with the response I received from the office personnel. The installer of the Generac Unit was very personable and answered all of my questions. The electricians were efficient and also took the time to explain the fuse box to me and what happens when the electricity goes off. They went above and beyond to help me program the Mobile Link monitoring system. I really appreciate how pleasant, efficient, and personable everyone was.

Quality work. Need to better coordinate site estimate details with installing electrician. Otherwise, the final solution exceeded expectations.

Matt H.

Your service man Cal did me a service, and he was solid with his ethical take on doing his job well and he did. He literally went the extra mile by going to the hardware store for a part for me, rather than disconnecting a hanging lamp and taking it in. What he did with tools-of-the-trade would have been beyond me at any time. Skilled, polite, and aimed to please. It speaks well of YOUR company that you employ people of his caliber.
