    James Wagner from Donnely was the technician. He was very professional and courteous. I had a bad transformer that was replaced. Overall, very satisfied. Samuel Russo performed a routine Electrical inspection of my property, and I could not be more satisfied with the experience. He was extremely diligent, professional and courteous throughout the entire process. I really appreciated how patient and clear he was when answering my questions. Overall a very positive experience.

    Absolutely positive experience. Very professional. Jim was amazing. Showed up at time stated and fixed the clog in the sewage line. After about 2 weeks it clogged again. They came back and fixed it again without hesitation or charging us a second time. They back their word. Highly recommended.
