“Even though I have a Commers unit, I chose to work with your company due to your great reviews (Commers didn’t have particularly good reviews) – Your honest, no-pressure sales/service approach is appreciated!”

Victoria - Mounds View

“Great! They delivered salt for a softener that they installed for me a few years ago. They were on-time and polite. They stacked the salt bags next to the softener for me so it would be easy for me to pour the bags in if the grandkids can’t come over! Nice guys.”

Janice - Plymouth

“I like their smaller 25 lb. salt bags because I can lift them and price is fair. Repairs have been prompt, efficient and done right the first time. We feel well taken care of by Peterson.”

Virginia - Wayzata

“I was very pleased with my experience as a whole with your company, especially A.J. who did the install this morning. He was on time and did a good job installing my unit efficiently as well as being very personable and answering all my questions cheerfully. I will recommend your company and equipment whenever the chance arises. Thank you for the great service and reasonable prices.”

Matt - Shakopee

“On-time and fast installation. I will be requesting salt delivery through them. It is just as cheap as getting it myself, but with no heavy lifting for me!”

Doreen - Maple Grove

“We had an awesome experience with Peterson Salt Co. We found them online as we needed to replace our water softener. From John’s expertise in explaining and answering my questions for the sale to AJ’s knowledge and professionalism at the install, we couldn’t be more pleased with their service. We will recommend them to our friends and family.”
