Overall rating: 5⁄ 5

  • Geo Man

    The best service, equipment and no pressure sales. The quarterly salt deliveries are full service, they bring the salt and load it into the softener for us. I recommend this Culligan for all your hard water needs.

  • Jo Bax

    Great service, friendly people, and a good value. We love our in-home salt delivery service too.

  • don wiesinger

    Use the salt drop off and it has worked well over the years as well as the tech always checks the system to make sure everything is working correctly. Great Service.

  • MsMerryland

    I love Culligan. The equipment works great and most of all I love that I don’t have to mess with it at all. They take care of all the upkeep and refills and whatever I need which is perfect for me.

  • barbara reitz

    The staff are experienced and patient, helping me to understand the principals and value of using various components of their filtering system. The owner has been very responsive regarding delivery needs and also responded quickly and responsibly to some property damage done by a delivery truck . That speaks volumes!!
