“My water softener installation was scheduled for 10:00 – 11:00 a.m. Peterson Salt’s installer arrived at 10:00 a.m., got right to work, and was finished a little after 11:00 a.m. He also took out the old unit, cleaned the work area and delivered 6 bags of salt. He was gone by 11:30 a.m. The unit works great and the installation was efficient and professional–I couldn’t have asked for more!”

Eric – Chanhassen

“I thought I had to replace my water softener; Peterson Salt came out and fixed it for me in less than an hour. I was ready to have them install a new one and was very pleased that they even offered to fix my system rather than replace it! They were very reasonably priced and polite, and I plan on using them again when it’s time to replace my water softener system.”

Chris – St. Louis Park

“I really like these guys! They were very careful in their work, gave me a fair price and discouraged me from buying more than I needed.  I checked the Web and thought I got a great price on a high-quality unit.”
