What our clients say

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!

We are extremely pleased with Culligan for the excellent work they do and for the awesome customer service. From the time we received our mailed reminder, to our phone conversation, to our Service guy - Chris C. He was very respectful and courteous, and took his time explaining water system and water softener. He was quick and had an answer for every question I asked regarding our system. Thank you so much for always providing great service. We definitely recommend your company to all our friends and family.

Your service man, Marco Hernandez, did an exceptional job replacing filters and restoring the drinking water quality of our home! Thank you Culligan Water. We appreciate the quality of service you have provided these last few years.
