  • Donna Myers

    We are a Rock Quarry and with 5 guys working outside in this Hot weather we go through a lot of water.We use to go get our own water and bring it back to our office. That became a real pain for certain employee's. Finally we decided to start a Culligan Service. It has been the best decision we ever made. We are set up for a once a month delivery, they pick up empty bottles and bring new ones every month. With the weather getting warmer we were going through our bottles much faster, about 2 weeks before our delivery time. I called them on a Thursday (right before a holiday weekend)thinking I could set up delivery for the following week but they came out the next day (Friday) and took all the empty's, left us all full ones and then left us 4 bottles more then we normally get. Thank you Culligan for your fast and Friendly service and for keeping our guys hydrated.

    Awesome service and delivery...Exceptionally consistent for 9 yrs.!!! We're very appreciative to have this water source as our tap water is toxic. Thank You! Stiarwalt Electric

    Great service, will definitely use again. Matt provided great service in helping us with the water quality on our private well water. He was determined to find and fix the cause of our water issues. He discussed some expensive options to replace our softener system, but thought that overkill and recommended starting with a simpler, less expensive solution (pre-sediment filter). I appreciated the honesty. During the process he explained a lot about water quality and how it's impacted by our well, softener, and reverse osmosis system. That's paid dividends in letting me better maintain the systems since.

    I love the convenience of home delivery. Owning my own dispenser makes it affordable to enjoy great tasting water! Thanks, Culligan!!

    We had our Culligan system installed 15 years ago, when building our home. It's something we never have to spend time with, salt gets delivered always on time, and we're set.
