  • Carolyn Pavlovic

    We have been using our Culligan water softener and reverse osmosis system for a month now and love it! The installer did an excellent job, using all his plumbing skills to successfully install both systems with our "challenging" plumbing! He also connected bypasses to our outdoor water faucets. We've lived in this house since 2004 and can finally take baths. Something we didn't want to do with our untreated well water. We also enjoy using the "button" to access the reverse osmosis water through our kitchen faucet. Our humidifiers work much better with the RO water. We are very satisfied customers and look forward to many years of good quality water!

    We moved into this house a year ago and didn’t realize how hard the water was. The previous owners of 20 years never installed a water softener, so I thought, how bad can it be? I immediately noticed a difference, my hair and skin were dry, my clothes were fading fast and there was the water stains all over the sinks and showers. I lasted about a year, then called Culligan of Merrillville. The experience start to finish was excellent. I had a couple estimates and their pricing was competitive. Everyone I came in contact with was knowledgeable, friendly, polite and professional. I love the water softener and the reverse osmosis system. I highly recommend Culligan of Merrillville.

    I moved to Cedar Lake Indiana in October 2020. I was referred to get Culligan to install my water softener system. I am very pleased with everything so far. The person who hooked it up did a great job and he explained everything in detail how it operates. I also like the fact that they will deliver salt right to my home and even install it for me.

    We just moved to the Dyer/St.John location beginning of July. We never had to deal with water softeners and didn’t know too much information about it. The Culligan team was very helpful, informative, and professional. We have no complaints about our service and we see a big difference in our water since the install. We chose Culligan based off of reviews and we are happy we chose them. Happy customers!
