I have used Brandon before and since his merger with TSI. The friendly and knowledgeable service I used to get with Braco is still as good as it ever was. I won’t use anyone else.

What a wonderful experience. I was not able to give my full attention to the instillation of my generator. TSI took care of everything, freeing me to complete other tasks for a new home owner. The gentlemen were polite and extremely knowledgeable. Thank you for taking out the hassle of hooking up the generator.

I called TSI to help replace our garage door opener and upgrade our electrical panel. They had somebody over in just a few hours. They were respectful and I couldn't be happier and now I can open my garage from anywhere on my phone. If you need any electrical work done, call TSI
