Tim did an excellent job quickly diagnosing the electrical issue in our home and repairing it right away. He was very respectful and maintained safe social-distancing for COVID.

We put in a request for service with American Home Shield. Tim was sent to help us with our issue. He was extremely knowledgeable.

Highly recommend and would definitely use again!
