Very pleased with the service from Culligan. All of our questions were addressed and the whole process was explained. We purchased the Water Softener, Whole House Filter, to include the Reverse Osmosis System. Professionally installed, and on time. We researched water softener’s for about six months and elected to go with Culligan. Yes, you can purchase these systems online, however, you do not get the local support, not to mention all of the negative reviews we have seen from these online retailers. You would also have to pay the install, and that can come with a hefty price. Five Stars for sure. Thank you Culligan!
