I recently had a service call to change my filter. I have had your service for 18 years. I cannot commend your tech “Will” enough. He was amazing! He took his time and did a very thorough job. My facet was loose and I had asked the previous tech to fix it but he said that’s the way it was. Will fixed it prefectly. Thank you so much! Will is an outstanding employee to your organization.

I love my new water softener. My son has eczema; we have tried creams, lotion all of which were very expensive. I was told by a friend that a water softener may help. While it has not gone away completely the difference is night and day. Thank you Culligan!
