Reviews for Culligan of Merrillville
Overall rating: 4.9/5

We had a great experience with Culligan in St. John. We are new to the area and were not familiar with a water softening systems. We worked with Jon who explained the water softening process and the benefits of a reverse osmosis system for drinking water. We are very happy with our purchase and had a great experience. Thank you Jon for your exceptional service!

Dan Halsted and his Culligan team have done a great job in giving me the best quality water. They are responsive and courteous and always show a great deal of expertise in their work. I would highly recommend them!

Getting set up with Culligan drinking water was a great experience starting with meeting John in the store where he educated us on the Culligan water system and what we needed to have in our home. When the time for the installation came it was a fairly quick process (2 hours or so) and everything went very smoothly. Using the water has also been a great experience. Coming from Lake Michigan water we weren't sure exactly how the water would taste or feel. Thankfully it has exceeded our expectations. Drinking the reverse osmosis water is very comparable to drinking Lake Michigan water and using the soft water for things like dishes or washing clothes is pleasant and doesn't leave an odor behind.

Sales Rep Jon Turpa was AWESOME, he was a pleasure to work with! Very knowledgeable and patient in explaining and answering many questions about my new Culligan system. The company kept it's promise with my delivery/install date. They were the only company during my new home build able to deliver as promised during the panedemic.

Jon and Chris were very easy to work with, professional & easy going, as well as knowledgeable!
