We finally decided to get a water-softener and whole house filtration system about 3.5 years after moving into our new home un San Marcos. We interviewed several companies and decided to go with Culligan Water. Jerry came out to test our water and was very friendly and knowledgeable. We also opted for the under sink RO filtration for food and drinking water. Culligan is a full service company that stands behind its products. We can count on their being there for us when we need them, including salt delivery and 10 point inspection every three months (for a small fee and cost of salt). Chris and Zach were very polite and did a great job of installing and explaining our system and how it worked. They even worked in the very hot attic on a very hot day to connect the plumbing, including running a connection to the drain in the laundry room. At the completion of the installation they made sure every thing worked well and that there were no leeks. And cleaned up everything really well. Overall and A+ job by Culligan and its crew!culligan

My experience with Zach and Kevin was excellent. They are very professional, respectful and strived for a quality installation. They made sure to clean up the worksite before leaving. The quality of your employees reflects on the quality of your company and earns you the great reputation you have.
