  • Michele Dinaso

    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.

    Extremely nice people on the phone. I wasn't on the delivery list for some reason and they fixed the issue and I received my water delivery. I can't say enough when a company goes above and beyond to make sure you are taken care of. Very rare in today's cancel culture we live in today. Highly recommend this store for all your water need .

    The technician that came out was very knowledgeable. He knew the ins and outs of my softer.

  • Gina Mary McDonnell

    My tech Justin was extremely thorough and helpful! He explained the entire process as he was going along and did not push for anything other than what we needed! He arrived promptly and was done in an hour. Thank you very much for your service today, I hope you continue your path with Culligan as we would like to have you back should we ever need you again!

    Dan the owner has been standing behind the Culligan product that I've only had for about 15 months since it was installed. I started having issues with the Iron cleaning tank around 11 months and he was on top of it. Chris is a phenomenal tech, he is very professional and knows the products very well, I would strongly recommend asking for Chris if you ever need service or a new install.Although I'm satisfied with the service that I'm receiving from Dan and Chris I'm however disappointed that I started having issues that early with the system and I hope that the issue has been finally taken care of and I won't have any problems for a long time.-Tony
