On time service, friendly and professional personnel and always in communication with us in regards to deliveries.
We’re so grateful for Anthony & the team at Culligan! The difference between our water, drinking and showers is night and day. My husband even noticed how soft our skin feels after a shower. Thank you so much, welll worth the price!!
Fair price and excellent service
Everything was seamless from the sales rep to the installer. They all seam to have good knowledge of the product. I really didn’t think Culligan would make as big of difference as it did . Our water softness and less iron is amazing. Thank you again.
I have dealt with Culligan for years with salt delivery for the water softener. Now purchased a water cooler with bottom loading. Love it😁 2/17/25 Had slight issue, with tube freezing, but they handled it. Naomi was very patient with me. Very good customer service.
Flexible delivery schedule. Friendly employees. Quality product.
Everyone has been incredibly helpful and super nice! We love our new water filtration system. I no longer fear to drink our water! Thank you!!!!
The gentleman was very knowledgeable and did his job well. Thank you.
Tony is fantastic to work with!!
Great service and follow up and always friendly!
Softener was not working and softening our water.
On time. customer service. communications
Great and dependable service. Down to earth people with no pressure sales involved. Have been servicing our equipment for years. NEVER an issue or concern with Culligan. The only thing they could do better is to bring the donuts with the salt delivery (just kidding!). Highly recommend them for your soft water needs.
Tony with Metzners was like a scientist with all his vials, droppers, test tubes! It was very helpful to see the differences in water quality from different sources in my house.Thanks for helping me clean up my water.
Tony at Culligan’s has a vast amount of knowledge and experience with water and water filtration systems. Can’t go wrong with Tony and Culligan!

100 % satisfied
Very friendly and dependable service. If you aren't home for a delivery (and feel comfortable doing so) you can leave an entry open for them,let them know how to get in, and they deliver and fill your salt tank. They also take care of your equipment (if needed) in a timely manner.
I have been a water softening customer of Metzner's for a couple of years and recently decided to add a RO system to our home. From the initial call, the consult with Tony, the install with Chad and the follow up visits Metzner's delivered exactly what they said they would. The consult was thorough, the install was professional and not only did they do an onsight follow up to ensure no issues / leaks; they also did a phone follow up to ensure I was satisfied. I strongly recommend Metzner's Culligan to anyone looking for a water softening or RO solution. Thank you!!
Excellent service and attention to detail.
Reliable and always conscientious
For many years have had reliable salt delivery and periodic inspections for my water softener. All good and no complaints.
Great service. Great water. No issues. Culligan is extremely professional and kind.We have had Metzner’s Culligan drinking water for 5 years. How many plastic water bottles is that? Saved. Handled. Purchased.We liked it so much we now have their water softener, which has also been working so much better than our other one that just didn’t meet our needs. (Kaukauna)
Very satisfied as they are so knowledgeable and very good to work with.
Will recommend them to everyone
Great service and excellent that they carry it down the basement steps for us!
