The Culligan Chicago difference
We've been leasing a high-end sulfur filter from Culligan of Wheaton for the past five years or so, after we bought one of those from them sixteen years ago but then it died after many years of continues use. The leased unit never gave us problems until recently (or so we thought). We detected a slight sulfur odor in our water so we called Culligan of Wheaton. They came promptly, assessed the situation, and couldn't find any strange odors. However, they did notice that our filter was not the latest model so they replaced it for the latest, state-of-the-art, one. This model does not require a bottle of bleach every month. It's self-cleaning. It's great not having to refill the bleach bottle anymore! By the way, the sulfur odor is now gone! I'd highly recommend Culligan of Wheaton to anyone who needs ANY type of water work done. They have been great doing professional installations and pipe work too for us for the past sixteen years--and counting!
Every step of the process was painless. The initial sales appointment was informative and easy to understand. I never felt Ike I was being pressured but only educated in my options. The sales rep Gary was an absolute pleasure to deal with. Installation also could not have gone better. As someone who works in the trades it was refreshing to see that there was care and effort put into to the layout of the pipe routing and placement of the unit. The installer was prompt and professional and completed the job in a timely manner. The space was left clean and free of any scraps or garbage. In dealing with the office since the installation everyone I have talked to has been cheerful as well as helpful. I would recommend Culligan of Crystal Lake to anyone who is struggling with water purity issues. Gary made the process so easy and informative that choosing the correct product for our needs was very simple. Keep up the good work Culligan of Crystal Lake!!
