Great service! Friendly sales and install staff
Satisfied with the service. Chris, one of the service techs, is awesome and helpful!
The service man, I think his name is Chris, was very professional, easy to communicate with, and most efficient. Culligan is fortunate he represents the company.
Fill your 5 gallon Jug of water for $1.25, they have a self service in their front entrance. Best water hands down
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.
They have Xtra filter for hight ph levels and alkaline water
Both service reps that helped me were so friendly and knowledgeable. They answered all my questions! Thank you!
Great service and prompt delivery
Culligan has been great for my family.
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.
Fantastic customer service!
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!
Painless to have one installed and very cost effective. Didnt realize city water was not as filtered as I thought
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.
Nice sales person. I love that they deliver the salt, and will put it in the tank for you!
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
Great service & employees helpful when I call, I highly recommend Culligan for water softener & salt , delivery is outstanding!…
Great customer service
Great service.

Water Softener FAQs

Culligan Water offers a full-service installation to make getting started with your new system even easier.

The average installation takes about 2-4 hours.

Watch: What to expect at Your Water Softener Installation

The price of a Culligan water softener will depend on the system as well as its features, efficiency, durability, capacity and more. Culligan Water offers flexible payment plans whether you choose to rent, purchase or finance. Schedule a free, in-home consultation today and a Culligan Water expert will help you determine what your home needs.

Water softeners work through basic chemistry. The main tank of water softening systems is filled with negatively charged resin beads. Meanwhile, hard water is caused by high amounts of calcium and magnesium, which are both positively charged molecules. As hard water pumps through a water softener, the calcium and magnesium are attracted to the resin beads and removed from your water.

To help determine the appropriate size for your water softener, your local Culligan Water expert will assess factors like the hardness of your water, household water usage and flow rate. Schedule a free, in-home consultation today to get custom recommendations based on your home’s needs.

If you’re dealing with the unfavorable effects of hard water — like dry skin and hair, limescale buildup around faucets and showerheads, soap scum on shower walls or too much wear and tear on your water-using appliances — you may need a water softener. That said, remember that not all systems were created equal. With Culligan Water, you can rest assured that you’ll get a full-service partner, quality products with durability and an established brand you can trust.
