Ladies and Gents, I did my due diligence and I love this place. I had Jerry as my sales guy and he gave me the most amazing deal and had the system installed exactly as I asked. Ray and Tyler are fantastic managers that are always ready to serve. The whole team at Culligan really does look out for the consumer. They aren't a fly-by-night scheme. Their products really improve your quality of life.

We recently had Dustin Broune come out and look at our clubhouse water softener. Dustin came out very quickly, was extremely knowledgeable and customer oriented. He took the time to explain what he thought we needed he did a free water test and also explained how the system worked. He told me that he would send a bid on Monday and by Monday (today ) before 10 am I had the bid. I would recommend Culligan Water of San Marcos 100 %. Thank you Dustin for your excellent customer services.

A Month ago, May 11, 2022, Jerry Gissiner came to gives us an assessment for a water softener system. My brother was here since he has had a Culligan system for many years. and would be able to ask the questions that I wouldn't think to ask. Jerry way very informative and was not a pushy salesman! I was very impressed. I was sold!!!.The installer, Jo Jo and his assistant came a few days later. They did an exceptional job. They were very efficient and professional. I was very pleased with their installation. I am vey happy with my Culligan Water Conditioning system.
