A & J Generator & Equipment helped us out last year during the storm and urgently fixed the issue with our generator. Sandra is simply AWESOME!!! She is super responsive, vey nice and professional and got someone out to immediately to fix our issue. She is a pleasure to work with and made the process easy for us. We also worked with the company (Tony and his team) to move our generator this year. They did a terrific and clean job. I will be referring them to my friends and family. Thank you Sandra and Tony! It is a pleasure working with you.

With all the crazy weather we’ve been experiencing, especially Connecticut of all places receiving hurricane strength wind, it was time to get prepared. My family and I purchased a generator from A&J last week. Tony and his team came, installed the generator, made sure it was functioning properly, squared up with us and then left. Everyone was extremely professional and friendly, made for a very easy experience. Now I won’t be sitting in the dark next storm. Thanks guys! Great work!
