We are a locally owned and operated company, with over 30 years of experience in the industry. Water Softeners eliminate the effects of hard water. They soften the water by removing the calcium and some forms water iron found there. This extends the useful life of water heaters, washing machines, dishwashers, coffee makers, humidifiers and household plumbing systems.

"great service"

Aquarius Home Services is the top home service provider in Minnesota and Wisconsin. Offering expert service in HVAC, Water Softeners, Plumbing and Electrical . Our work is backed by a 100% performance guarantee.

"Nick was waiting for me when I came back from an errand. He was very good at explaining what he was going to do, then did it, then explained what he found. Very professional! Aquarius should tweak their scheduling plan to incorporate windows of when the tech will arrive. The current method of announcing that the tech will be there without stating when is very inconvenient for the homeowner."

BWS Plumbing, Heating and Air Conditioning is a full-service Plumbing, Heating, and Air Conditioning company that provides a one-stop service experience for the business or home owner. Our team of professionals are among the most courteous and experienced in the Twin Cities. We will provide you with the very best service in a fast, efficient timeline at the most economical prices. We are known in the industry for our specialized service and installation of Heating, Air Conditioning, Plumbing, Electrical, and Energy Services. No project is too large or too small for our team.

"I have a home warranty on my recently purchased home. The home warranty company contracts with BWS. The tech, Ryan G, came to my house on 6/24/21 to assess the plumbing issues I discovered after I purchased my home. He told me on 6/24 he would be requesting approval from my home warranty company for the repairs/replacements, then they would need to order parts, and once the parts arrived, would be able to schedule the service. It is 7/8/21. I have been trying to find out from my home warranty company about the delay. I was informed today by my home warranty company "regarding your plumbing request, the technician has not submitted a full diagnosis, but he did call in to advise us that this was a flipper house that was purchased as is and there was no inspection done on the home. I have requested the diagnosis from them. I will follow up with you once it is received." This comes as a HUGE surprise to me as I purchased the home for myself, for me to live in. The housing market is tough right now and many buyers are bypassing inspections so their offers don't get passed-over by sellers. It is definitely a fixer-upper since it was a cat and hoarder house that had been neglected for over 5 years by the previous owner. Someone prior to that owner had done quite a few DIY projects. The house has good bones and needs cosmetic work (flooring, walls, trim). I previously owned and lived in a 110 year old house for over a decade and did many of the renovations myself. I have YEARS of plans to make my new house and yard exactly what I want and need. After the purchase of my house, I had ripped out all of the cat-hair-and-grime-covered flooring, window trim, baseboards, and window treatments. And then I broke my arm. Now most of the projects I had planned are on hold as I cannot use my left arm for anything for at least a few more months. In the meantime, for my home to be ready for me to move in, I need some plumbing issues fixed that I discovered after the purchase of my home. Hence the request for repair through my home warranty that was sent to BWS. While the tech was at my house, I was displeased with his attitude and the way he spoke with me. He treated me as though I were unintelligent, didn't know what I was asking about with my house, didn't know what my home warranty contract covers, and was very dismissive. BWS has not performed any service. They have not followed through with making the request for approval of repair/replacement through my home warranty company. The BWS tech instead took it upon himself to go out of his way to call the home warranty company make false statements to them about me, my house, and my property. I sure hope this is not the type of customer service BWS does for everyone. But then maybe he treated me this way because I am female and have a broken arm."

Water treatment & purification system repair or services FAQs

If your water softener is over 10 years old or if repair costs approach the price of a new unit, it might be time to replace it. Most water softeners last between 10 and 15 years. Replacing an aging unit can improve your water quality and help you avoid frequent repair costs. For a newer system with minor issues, repairing may be the best option. Consider the age and condition of your system to decide what's most cost-effective.

Water treatment systems remain dependable for 10 to 20 years with proper maintenance and care. A well-maintained system secures full performance by following a scheduled upkeep plan and professional inspections. Consistent maintenance guarantees continuous water purification, ensuring that the system operates at its peak efficiency and delivers high‑quality water throughout its lifespan.

Faulty water softeners exhibit clear symptoms that signal the need for immediate attention. Noticeable mineral build-up around faucets, discolored water, dry or itchy skin following a shower, and altered laundry texture indicate that the system is underperforming. Recognizing these issues early and addressing them promptly prevents further damage and maintains optimal water quality. Early intervention ensures that your water system continues to operate reliably and efficiently.
