What our clients say

There’s a reason Knoxville Culligan is the best water treatment company in with over 35 4.4-Stars Google Reviews.

It is a pleasure working with Culligan Water!! Greg is always respectful, friendly and has impeccable timing delivering our water while we are on our last bottle. We are grateful for your services and highly recommend.
They have always provided great customer service since the first time I dealt with them. I have dealt with Culligan for over 20 years. It really improves the quality of the water. The reverse osmosis system turns any water into bottled water quality. So you eliminate all of the plastic bottles. I have dealt with the same honest, knowledgeable and friendly people the entire time.
Friendly knowledge staff
New customer. The installation was quick and professional. Super impressed already seeing results.
Courteous and responsive.
Very thorough, good communication skills, would highly recommend
New customer review. Bret was great. He did the initial assessment and let us now what we needed to have done prior to the installation. The installation went smooth with no issues and everything was installed with ease of access in mind. Service and product are amazing. Can not recommend Bret and Culligan enough. Thanks for the soft water!!
Brett came to troubleshoot our Culligan water softener in the home we purchased approximately 8 months ago. He was able to diagnose the problem quickly and had our water softener up and running in less than half an hour. He was so friendly and helpful and we definitely will contact Knoxville Culligan for any future needs.
Culligan provided excellent service and continue to be available when I have questions. The water quality has improved in the house. Culligan was almost $4,000 cheaper then another company that provided the same service.Appreciated the estimate was very responsible and we did not have to banter to get the price down to something reasonable.
I recommend this system to anyone with hard water.
We have had our water system serviced yearly and replaced once by Knoxville Colligan. They have always done an excellent job. Show up when they say they will, and clean up after themselves. I also choose to go to their office to pick up my extra salt, and they always load my car for me. Great guys!!
We had a whole house water treatment system installed in 2009, and the performance has been outstanding.The water taste is very good and it’s eliminated the significant deposits and discoloring around sink and shower fixtures.The Culligan Team has always been very responsive to questions and routine maintenance needs over the last 9 years!
Mike and Daryl are straight shooters and meticulous with thier professional services. I love my water systems. I have both a water softener and RO system in two locations. My coffee is wonderful. Because we have hard water my skin was drying out. My skin loves the water softener system.
The products are a game changer and Mike was awesome to work with, very professional.
We have had our system for going on two year now. Installation was professional. In addition to whole house system, we had reversed osmosis system installed. It was hooked up to a faucet on our kitchen sink as well as our refrigerator, so ice and cold water from there are perfect. Follow up service/maintenance has also been stellar. Highly recommend.
Installed professionally and works perfect. Water is soft: dishes cleaner and clothes cleaner.
We had a great experience from start to finish. Our installer (who also sold us the unit) was professional and courteous and followed through on every promise. We are very happy with the results. I've always hated our tap water, but am happy not to have to buy bottled water anymore!
Great service and very thorough ✅
I'm not sure how long I've had Culligan BUT the service has been impeccable.!!! From the Installation to just Regular Maintenance - everything is Perfect.!I do my best to deal with Mike but the other techs have been awesome, too.!!!Contacting, Responses, and Professionalism is Always Better than expected.!I have ALWAYS had soft water and I always will.!!!Thanks Culligan.!!!Hey, Culligan Man.!!!

Mike provided me a great product at a great price.
Outstanding customer service. Mike was very attentive and professional. I highly recommend Culligan for your water treatment needs.
I have had occasion to work with Mike at Knoxville Culligan Systems several times this fall. Before he even came to the house he was so helpful on the phone to make sure I didn't have any issues before he arrived. He's always been prompt, courteous and thorough in explaining my system to me and ways I might improve upon it. I absolutely highly recommend them.
Very professional
We have Culligan water softener and drinking water system in our home. I can't express how great our water is now. Staff is very polite and very professional.
We have used Culligan's for several years. The staff is professional and courteous. Our driver is unbelievably kind and helpful in loading and unloading the water jugs. Everyone is friendly and easy to work with. I am very impressed with the quality of the water (and we are particular!) and the quality of the staff.
This water makes city water taste like pool water. Its worth the money especially for making coffee. I couldn't figure out why the coffee at work tasted so bad until we got Culligan.

Water Softener FAQs

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.
