We were not getting soft water from our water treatment equipment and I couldn’t figure out what was going wrong with it. The technician came out and determined the problem right away and has the parts right with him and was able to repair it and now we have beautiful, soft water again.

I have been a Culligan customer for 21 years. The service, the people, and the product are the best. Would not go to another company.

great team, excellent install of 3 sink RO systems in my triplex + water softening for entire building. great rental program that includes annual filter replacement (which are normally like $400). Writing this review today because I had a leak at one RO faucet on a Saturday, they immediately answered the emergency pickup line, was something they were able to walk me through to fix, took less than a minute. highly recommend!

We have horrible water from our well, so we need a high quality system to allow us to have safe/clean water coming through our house. We compared products and services, as well as pricing, with other local brands and found Culligan to be the best overall product for our household needs. They were extremely nice and thorough with their installation and removal of old equipment. Everything was cleaned up, and functioning properly when they left - and no problems since. We are now 10+ years satisfied with Culligan.

I appreciate the service so I don’t have to lift the heavy salt bags and my softener always works well. Also I have a water purification system in my kitchen and have had excellent service for that as well.
