Our system started leaking last night and we had to turn the water off to the house. I called the emergency line and Dalton came out immediately even though it was 830 at night. He promptly fixed it and in fact, upgraded our parts so we wouldn’t have any problems in the future. He was pleasant And friendly. He was a real lifesaver.
Andrew was fantastic—friendly, professional, and easy to work with. He was extremely knowledgeable about the products and took the time to walk us through the options, ultimately helping us select the one that best fit our team’s needs. It’s been a perfect addition to our breakroom, and we couldn’t be happier!
Lisa High was our sales person. She was very personal and friendly. No pressure to make an immediate decision, she just explained options. Our Culligan water feels great, tastes great, and we no longer have to squeegee the shower doors!
Dalton came out today to service my water system. He was very friendly, knowledgeable, and timely. He went above and beyond for me. I truly appreciate the exceptional service that was provided by him and the company. I would recommend Dalton and Culligan to anyone looking for a water filtration system. Thanks for the great service!
