Indy Soft Water
Website: indysoftwater.com
Address: 4148 W. 99th St.
Contact: (317) 228-9822
Hours: 24/7
Indy Soft Water stands out because it’s a certified woman-owned business that actually guarantees an average 20-minute response time on business days. That kind of speed isn’t common, but it’s very helpful when you have a water emergency.
I actually called them once when my old softener started making a weird noise, and they got back to me right away.
Their WQA-certified technicians really know their stuff and have over 26 years of experience. This reassures me that I can trust their treatments.
While they mostly focus on simple filtration solutions, they also offer specialized systems for both hard water conditioning and well water.
However, you do need to schedule a consultation before receiving standard pricing or financing details.
Customer Reviews:
We use Indy Soft Water for yearly maintenance and salt delivery, and they’ve been great every time. Austin recently serviced our system and was friendly, professional, and thorough. We really appreciate the dependable service and highly recommend them!

We bought an RO and water softener system one year ago. Today Austin and Jack (Indy Soft Water Service Techs) came to our home for a routine filter change and annual service. These guys were extremely professional, courteous, quick and skillful. Their focus was that our system was in tip top shape leaving us worry free.
Best provider and service company around.

American Aqua Solutions | An Alta Water Company
Website: americanaquasolutions.com
Areas served: Indianapolis, IN
Contact: (317) 954-2450
Hours: Mon – Fri: 8AM-6PM, Sat – Sun: 9AM – 4PM
American Aqua Solutions has a great mission. They partner directly with the Lifewater organization and donate a percentage of profits to support global water and sanitation crisis relief.
I also appreciate that they offer solid discounts for military personnel and first responders.
They use a patented Disinfecting Filtration System (DFS) technology that was originally developed with a US Military Grant. This system provides comprehensive air purification and water filtration.
Their drinking and softening systems are WQA-certified, and they do thorough testing before recommending anything.
A friend of mine used them and appreciated the detailed water analysis.
The main drawback is that they don’t have a designated physical street address for walk-in visits or parts purchasing.
Customer Reviews:
Lovely guys! They came highly recommended to me. Respected our home like their own. A nationwide company came and told me my softener wasn’t working— Jacob came right in and noticed the water was turned off from the softener and turned it on for me. The other company was just ready to pull the wool over my eyes to sell me a new system while Jacob had honesty and integrity to show me my current system and the way it worked. I ended up purchasing a full new water softening system and reverse osmosis system from Jacob.

My whole experience with American Aqua Solutions was great. From Jacob answering all of my questions and getting everything set up, to my tech David’s promptness and professionalism. David made sure to go over everything once the install was.complete and answer any questions I had. I would highly recommend them for anyone I know having issues with hard water.

Superior Water Treatment
Website: superiorindy.com
Areas Served: Indianapolis, IN
Contact: +317-207-6476
Hours: Flexible
Superior Water Treatment focuses heavily on integrating environmental responsibility and sustainable practices into its filtration technologies. If you’re eco-conscious, this is a major plus.
They handle both commercial and residential setups, emphasizing green practices across the board.
One of their best features is the automated salt delivery service, which ensures continuous, hands-off system maintenance. It’s very convenient not having to lug those heavy bags around yourself.
They also provide complimentary testing to verify your water’s mineral levels and check system safety. They even install and maintain commercial water heaters.
The company’s service footprint is strictly localized to the Central Indiana area. This means residents and businesses outside this region cannot access its system installations, maintenance, or bulk salt delivery programs.
Customer Reviews:
Excellent experience! Both the owner and the technicians are very knowledgeable and incredibly friendly. I had a water softener installed (to rent, although they also have the option to purchase) and it was done quickly for a reasonable price. I can’t speak highly enough of them – definitely worth giving them a shot for other products and services as well.

I have a water softener in my house from Superior and the deal they offer on it is pretty impressive. They installed it and removed my old box softener. There was an issue with our lines, which they were able to take care of in a very timely manner to get the softener up and running. Highly recommend!

Cooper’s Water
Website: cooperswater.com
Address: 9635 E. Park Davis Drive, Indianapolis, IN 46235
Contact: 317.268.8890
Hours: Flexible
Cooper’s Water is a family-owned operation with over 40 years of experience, and its main draw is that it uses exclusively American-made systems. They avoid cheap softening resins.
Even better, only their trained employees handle installations and repairs. They completely skip third-party contractors, so service is more consistent.
If you’re on a local well system, their specialized iron and chlorine filtration setups are highly effective.
They also maintain an A+ rating with the Better Business Bureau (BBB), which I think speaks volumes about their reliability.
They also offer a 12-month same-as-cash financing option, making new installations much easier to manage financially.
The company’s focus on premium, American-made water softening systems and components means their products tend to be on the pricier end. Budget-conscious customers may also find their product selection limited.
Customer Reviews:
Our experience working with these guys has been excellent! From our consult call with Doug, to our install with Abel, and our follow up visit with Mike they’ve all been so professional, friendly, and knowledgeable. No AI bots and long holds with annoying elevator music here. Just awesome people who care and provide great service! Loving the Hero water softener and filter along with our reverse osmosis system. Thanks so much!
- Angel Ampas | Google Review
Abel was great and came highly recommended, he answered all my questions and was very professional yet very personable during my install. In the beginning Doug was very detailed in explaining the different water systems and followed it up with an email with all the details including pricing. I Highly recommend Coopers Water!

Culligan Ultrapure of Indianapolis, IN
Website: culliganindianapolis.com
Address: 9220 Corporation Dr, Indianapolis, Indiana 46256
Contact: (317) 526-4305
Hours: Monday-Thursday 7:30am to 5:00pm, Friday 8:00am to 12:00pm
Culligan Ultrapure combines the serious technological backing of a global brand with local roots that date back to 1936.
Their standout feature is a complete 30-day money-back guarantee, which gives you a lot of peace of mind when investing in a new system.
They supply specialized equipment specifically engineered to target complex contaminants like PFAS, Chromium-6, and lead. Their systems are heavily tested under WQA industry standards and carry NSF Certification. They also offer a handy portable exchange service along with standard salt and bottled water delivery. The major downside is their highly restricted operating hours; they close at noon on Fridays and are shut completely over the weekend, limiting accessibility.
Customer Reviews:
The sales rep Nate was very informative which helped me make an informed decision as to which softener to go with.
The installation technician Zach was pleasant on the phone, moved us behind an appointment to accommodate my work schedule, he is also very knowledgeable as to how the softener works and what we can expect as our water will improve greatly.
- Terrell Hawkins | Google Review
Josh with Culligan was very informative and helpful. He knew the product and sold the value of the company. I had looked into other systems and he sold me. I also liked the 2 year same as cash offer. I also was sold on the HE system needing less salt and being able to take the system with me should I ever need to move, with culligan helping with the transfer for a small fee. I could tell the new system was working when I showered. Loving it 😊 !!
