“Very Knowledgeable”

We could not be happier with our experience with your company! The generator works perfectly, and you have always been responsive to any questions we have had. The young man who recently did the annual inspection of the generator was excellent. He was very personable and kind, and did a thorough job for us, explaining everything he did. We are very, very pleased with Karalis! Thank you!
