What Clients Say
I recently had my old water softener replaced (different manufacturer) and I'm so glad I went with Culligan. Andy did a great job in explaining the differences, testing my water and set me up with the correct softener for my needs, setup the install(which was very quick), and kept in touch to ensure all went smoothly. Matt who did the install was very courteous and did a fantastic job on installing the new softener, upgrading the system much better then the previous install, went over the controls and by-pass and left a clean area as if they weren't even there. He also explained about the delivery of salt(which I really like as I'm getting too old to be lugging bags of salt around) and was very sincere if any problems arose. All in all it was a great experience form the start and highly recommend them.
