working with Culligan was a complete joy easy to do. The staff knows what they are doing as far as how the equipment works and the installation. Steve really knows about the products they offer and can speak with a sense of authority about the products. Excellent person... Doug was also fully aware about their products and how they will work .... he was also just so nice and pleasant ............... I was not home when the salt was delivered but my husband tells me that was really a good experience . the at person was great about how that program works with the salt. Now perhaps with this new delivery system we will have more soft water than hard water we were ALWAYS out of salt . thank you so much cdagel
My experience with Culligan is absolutely 💯 great! The service is terrific, and I love their keeping track of when I will need more salt in my water softener! So very helpful, and the service staff that deliver the salt on time are prompt, kind, and helpful too. Thank you Culligan!

very professional…..ZERO mess left behind, after installation
I like getting credit towards my bill when I refer new customers to Culligan! They are always very friendly.
Great service!!!
We are very satisfied with culligan. They have given us great service. The only concern I have is the new $3.oo charge for sending the monthly bill for the rental of the RO system. I assume an option would be to pay that on an annual basis instead of monthly. Great business. Great service. Thank you
I never realized how good the service was in Watertown until I moved to Fargo. I highly recommend Watertown Culligan.
We love our Culligan service. reverse osmoses are severed every year and is the best water for drinking and making coffee. they even deliver the salt and fill the tank, which is hard for me due to back problems.
I am not very happy about being charge $3.00 for getting a bill in the mail.
I've had Culligan softeners for over thirty years, and have never been disappointed.I’ve known two generations of the family that owns the business. The service people are nice to deal with, and are knowledgeable. And they’re much better able to carry salt bags down to my softener than I am.I have confidence in who I’m dealing with,and that’s priceless!
Their service is top notch!
Great service . Always polite when they come to service our water softener. They also deliver our salt to our home . Been with them over 48 years !!
Quick removal of the old system and installation of the new improved softener! Knowledgeable technician and able to answer my questions during the installation.
Very thorough and professional people helped me with a new water softener!
The service is outstanding! Very friendly and knowledgeable. The representatives left everything clean and in good working order after installation of our Reverse Osmosis system. I highly recommend Culligan Water to anyone who wants to get drinking water that is free of chemicals, pharmaceuticals, heavy metals, and whatever else contaminates our water these days!
We love our reverse osmosis right there at our sink. Small town with very hard water- this makes me feel so much better about what my family is drinking- my ice maker and water from my refrigerator would never have lasted with this hard water - so it's well worth the money!They do all the maintenance free with rental and love the delivery service for soft water crystals too! Great local Culligan company!
Love that they deliver to our house and carry it downstairs! Also great service if their is a problem.😃
Quick response time from the time we asked for the service to the time it was installed. The difference in our water was very noticeable, from the dishwasher not leaving spots, to my hair and skin feeling softer after day 1!
They have always been so helpful and knowledgeable about the products. I love our softener and water filter.
Jason and his staff were very informative and gave exceptional service. We look forward to working with them in the future.
Excellent service
Love the personal service. Great products from great people.
Great service and very accommodating.
Did a great job, thanks
Had a problem with our water softener recently and placed a service call. This company was fast to respond and got us back on tract and our system repaired.
The Culligan staff are very courteous and efficient in their service and delivery. They are always conscientious about entering our home and wearing booties when going down our carpeted stairs. This is a plus! We highly recommend this company for your water needs!
Jason and everyone at Culligan are great to work with and super helpful!
