I had a flood in my basement & thought it was coming from water softener. I called Guthrie & Frey &…read morethey sent Aaron out that same day. He came prepared with anything he needed, even if he had to rebuilt it. Turned out it was not my softener. Aaron took a quick look around, found the leak was the float switch on sump pump, told me the size, so I could let a plumber know & recommended a couple in the area. I actually found one exactly the same on Amazon & replaced it myself! If not for Aaron, I probably still would not know where this flood was coming from. He is a great asset to your company! I really appreciated him going above & beyond, when most contractors do what they come to do & they're out the door. It only took him a minute, but it saved me from more headaches & a lot of money. I can't recommend Aaron enough!!!! 10 stars!

No mention about a refund of my prepaid amount and one week's prior notice. I had to call to find out what was going on and they blamed corporate. Typical of their usual poor customer service. They're only concerned with money -- and they nickel and dime you for everything and you never know what's included and what's extra. I had been a customer for 17 years. No more. Do yourself a favor and find a better company.

We have had numerous techs do this over the past 12 years and he is by far the most thorough person I have seen do the requested service and check over the system. The quality of his work was A-1.

On top of it all he had salt in his truck he was able to deliver. That worked out very well! MAR North Prairie, WI

While it worked better than tap water, it still left too much residue. The five-gallon bottles are heavy, unwieldy, and nearly impossible to open. Overall, the service is too expensive. It would be cheaper in the long run to have a reverse osmosis system installed. Customer service operators can be rude.

I am guessing we will need to end up replacing the water softener soon and they will be the ones we always use and recommend after today!

WARNING! Do not do business with this company. Zero Stars is not an option, unfortunately. They…read morewere sent out by my also worthless home warranty company last summer to assess a well pump issue. Without doing any kind of testing, he tells me I needed a new well dug! First, that's not a covered item and to dig a new well the depth that we have would cost me well over $25,000 (not a typo). When I balked at that idea he said, "Okay, I can put it in as a well pump replacement". RED FLAGS!! I decided to postpone doing any work. Fast forward to this year, I filed another claim and thankfully another company was sent out. They diagnosed it as a well pump replacement. I asked if I needed a new well dug and they looked at me like I was nuts. They did the work, and I paid my out-of-pocket share of $1,600 to him and HSA would cover $1,500, the limit for covered well pump work. I thought that was it until I get a call from the contractor saying HSA only paid him $1,000 because HSA told him they paid $500 to Krizan Well last year. Shortly after a heated conversation with HSA, Krizan Well called me because HSA asked him to (???) but didn't tell him the reason and thought I wanted to complete the new well pump (which is admitting that he did not do any work for me last year). When I asked why he charged HSA $500 when he did zero work he said "I did a lot of work" and when I pressed him to tell me what he did for $500 he said "I had to spend a lot of time on the internet looking up stuff to give you an estimate". SERIOUSLY??? $500 to look up the cost of a well pump and to send me an email estimate? DO NOT DO BUSINESS WITH THIS COMPANY. If your warranty company assigns them, insist that they assign a different company.
