Fill your 5 gallon Jug of water for $1.25, they have a self service in their front entrance. Best water hands down

Jorge Ferguson

Peggy 1st apologized for how busy they were and set my expectation for tomorrow or early next week. What a pleasant surprise when I got there and Tony and Tyler arrived to provide service. It was not only faster than I expected but service above expectation. They replaced the machine older machine and really impressed me with how professional and exceptional the service was. Great water system.

Culligan has been great for my family.

John Pursley

Every person we had interaction with who is very personable, efficient, and extremely helpful. I would recommend Culligan products to anyone as the physical equipment is very high-quality, and the installers know exactly what they are doing.The big plus is you can rent their equipment for a very reasonable price every month as opposed to buying your own equipment at a big box store, spending a lot of money and then having to maintain it yourself and install it yourself. and, if the equipment malfunctions or breaks, Culligan will be out and repair or replace it for no extra charge.You can’t go wrong with the Culligan man.

I had a flood in my basement when I returned from vacation. Culligan helped handle, clean-up and made sure the unit was working to its optimum capacity. I was so grateful for their kindness, professionalism and excellent work!

Bryan Lautt

Painless to have one installed and very cost effective. Didnt realize city water was not as filtered as I thought

MirandaRightsAgain

I love my Culligan water! Very professional, all the way through the first contact with Harry, to the install, to one trouble shooting visit. Many thanks!

Easy self water refill in front lobby open 24 hours.

Liz Woodsend

Nice sales person. I love that they deliver the salt, and will put it in the tank for you!

Matthew Baucom

Been getting my water here for years, delivery service is always good, I live on third floor, and its at my door on time. Wait time from ordering can be a week or two, so i have to plan ahead and keep a bottle around. Prices aren't bad, a little more than filling them myself, but it tastes better, and I don't have to transport them
