Customers About Us

We had a really good experience with Johnson Water Conditioning. Fair price, good installation. We can now drink our water and it tastes great! We also like supporting local businesses and they were certainly worthy. Highly recommended.

Once again Johnson Water came out and solved my water problem! I have used them in the past and will continue to do so in the future. From the owner, to Jason and the rest of the staff… I highly recommend this company for their honesty, professionalism and ability to solve whatever my old house throws their way.
