TYLER seemed very informed Very kind and respectful. Got the job done. His helper was kind too They w worked well together read more

Discovered that my RO system was incorrectly installed. The drain line was installed to my dishwasher drain instead of to the inch and a half drain under the sink. Called Carroll Water to come fix it. Best they could do was an appointment in a week! I also discovered that Carroll Water has been bought out by a Private Equity Firm and is in fact NOT locally owned and operated. Lastly it seems that Carroll Water installs proprietary equipment and won't sell parts to customers or other plumbers so if you buy from Carroll Water - your either stuck to them or stuck replacing their equipment when it fails. VERY DISAPPOINTING My plumber yanked their RO system out and installed a new one that anyone can get parts for. read more

Matt and Carroll Water Systems, offered through Costco, is the worst in Maryland, MD. The scheduler and service provider in Maryland, MD don't communicate. Please don't buy the product from them; they lack total customer service. The scheduler doesn't communicate properly after aligning with the customer's request for a window of 4 hours. The technician arrives early, as they say the 15-minute wait time starts from the time he arrives. They are very arrogant and won't wait a minute extra. I would recommend investors not fund this company. read more

I love my RO system from Carroll Water. Years ago , they set it up correctly to accommodate my kitchen sink and refrigerator for ice and water! Matt, my most recent tech was very knowledge And professional. Where they loose me is in their scheduling department . Clearly all the schedulers are educated to do is make appts. As the front line call center they should have some 'basic knowledge ' of the systems and at least forward any technical questions to a tech ! The scheduling department failed me. I wasted Matt's time and my money on an unnecessary service visit. We will be building a new house and Matt gave me fantastic advice so we will consider Carroll Water based on his ability to service the system. I will welcome a call from a tech manager or a scheduling manager or even the CEO to discuss what would make this company top notch and receive 5 stars. read more

Jake & Ed provided excellent service for me. They answered every question and address any concerns that I had regarding a service that was provided today. I would highly recommend them. Thank you guys very much! read more

Mark Snyder from Carroll Water did a great job servicing my home water softener. He was on time, easy to talk to, and clearly knew what he was doing. He explained everything in a way that made sense, and the system has been working great since. read more

I paid over $14K to Caroll Water for installing a whole house water treatment system last October. I was told that there is a maintenance plan that Carrol water offers. I told the salesperson that I am interested in enrolling into the maintenance plan and requested written information on the maintenance plan. I even called Caroll Water office another 3 times requesting details on the maintenance plan. But so far I have received nothing. It is not published on its website either. Very disappointed! Not sure how they do business like this. read more

She did a great job was quick and pleasant to work with. We have used Carrol water systems for a while and are happy with the service. We

Mark and Brandon were an excellent team. Very professional, tidy, and efficient with their work. Thank you for your care during your service! read more

The technicians did an excellent job, leaving everything clean and ready to go. We are very happy with the service.

Ken offered exceptional service. He was professional, knowledgeable, and addressed all my questions and concerns.

The Carroll Water office staff was very responsive to our water flow problem with the well and tank in the house which occurred during the snowstorm the week of February 22, 2026. The technician team led by James arrived first thing the next day, assessed, diagnosed and corrected the problem, gave us an estimate for future repairs that might be needed, and our water is now flowing normally again. We appreciate their very prompt and highly professional service! read more

I just wanted to appreciate Tyler Biden and his co-worker for their superb work, including arriving on time, delivering three bags of salt, and replacing the sediment filter. Importantly, Tyler shared knowledge about maintaining the whole-house water softener system. He is an amiable and honest person to the customer. Kudos to Tyler and his co-worker!!! read more

Young lady was absolutely awesome knows her stuff, and very personable! We were worried about our system since it's been over 20 years ago that we installed syste, but Delaney assured us everything is good read more

Jack Pinkine and his crew were great and did a great job! They were very court and helpful!

I purchased this system last year. I got a call for a yearly maintenance service and found out it will coat over $800. At that rate in 4 years, I could by a whole new system. Initially I purchased the chlorine filter with it and afterwards I felt I was upsold. Now it feels worse since it adds to the service cost. read more

I have been a customer of Carroll Water Systems for 4 years. Carroll Water Systems provided a system check today. I was very pleased we with the service. Additionally I have been very pleased with the results of having the water treatment equipment from Carroll Water Systems. Great job! read more

Extremely poor value. Carroll Water Systems sold me an acid neutralizer that CANNOT be serviced by the homeowner as it needs to be completely disassembled just to add calcite, and want several hundred dollars to service it each and every year! A tech from a competing company looked at my system and pointed out that calcite can be added to their system without tearing the entire system apart. The previous system may or may not have needed replacement, but at least COULD be serviced by the homeowner at much less expense! read more

Carroll Water Systems has been taking care of our water system in our home for 20 years and we couldn't' be more satisfied with there entire organization! From there wonderful technicians (Matt) to their office manager (Kelly)! Matt is extremely knowledgeable of our entire system and always keeps it running perfectly. He comes in with a smile, explains what he has done and we always look forward to see him! Kelly is also extremely knowledgeable of all the inter workings not only in the office but of the equipment as well. She is always a pleasure to talk with and goes above and beyond to answer my questions and make sure we are happy! I highly recommend Carroll Water Systems! read more

I called Carroll water to refill my neutralizer and asked how much it would cost before I agreed to the appointment. I was told it would be $200. I agreed to the appointment then the next day o called to ask if they sold water heaters as well. The lady I spoke to told me they have electric water heaters. When I told her I was looking for a tankless or hybrid type she said they had those but only electric ones, so I agree to talk to a sales agent about buying one. When the agent calls he says they only have tank heaters and I could get one of those and they can install it and he didn't know how I could have been told otherwise. The next day the tech comes to service the neutralize and says it's 400. I called Carroll and asked to talk to a manager and was told "she was busy doing something and would call me back". It's been over 24 hours and I still haven't received a call. I called this company because I thought they would be reputable but all they are is a bait and switch corp looking to scam you. read more

Our installer Chris was awesome. In and out way faster than we were quoted time wise and his work is super clean and looks/functions great! Edit after 2nd visit: Ray explained everything and showed us what we've already been experiencing with our new system. Such an improvement in water quality all around. So worth it! We got a water softening unit and it's worth every penny. Great service all the way. read more

After knowing I needed a water softener and water filtration system i decided on Carroll Water. The day their service was coming they sent Tyler and two other techs. The entire team was fantastic. They were knowledgeable, professional, and completed the new installation seamlessly. I definitely recommend them, the service, and the product. So far so good. read more

I bought a water softener several years ago from Costco. Carroll Water was the company providing and servicing the unit. The unit came with a 10Y warranty. Annual service is required. The system has run great since it was first installed. The technicians are top-notch. There is truly a huge difference taking an over-chlorinated shower that drys your skin or taking a filtered shower that leaves your skin with moisture. If you have water quality issues or concerns, Carroll Water can help you. read more

Two filters were replaced at 3 pm of 10-30 Wednesday, over 65 hours have passed, the water after new filter is still blur. I don't have water meter to test the data, I regret that I didn't ask your technician to show me the data after new filters were replaced. The old data was just fine as I show your technician the WiFi indicator. I did not call for replacing filters, and actually i postponed your call to replace filters in August. I do believe we should follow the water indicator to determine when filters need to be changed, not by your schedule. If next few days the water is still blur, I will call you. read more

We had a whole home Eco Water softener and RO system installed without issue. My wife and I are very satisfied and the quality of work was excellent. read more

Outstanding customer service and reliability...no one comes close!! Had a an issue with water softener over a weekend. System was leaking water/not functioning properly. Contacted Carroll Water early Saturday morning. Technician (James) contacted me within minutes. Asked for a couple of pics so he could quickly assess the severity of the issue. Instructed me how to stop the leak and arranged for an onsite visit Monday morning. Technician (Mark) arrived... determined issue, addressed all my concerns, and quickly completed the repair at no cost (enrolled in maintenance program); extremely knowledgeable and professional. The best service ever! Highly recommended. read more

I would give this company zero stars if I could. PLEASE take my review seriously. This company came to our property this week to do some well work and drill a single line to our house. They were the most disrespectful and destructive team of contractors we have ever worked with. They used a backhoe to install what a trencher could have done, with far less damage; they installed the well through the septic field without checking with us (which means it's not to code and has to be redug); they broke our fence; damaged mature tree roots; and cut through a power line. It will take thousands of dollars or our entire summer to fix our yard, the latter if we do it ourselves. I am still shaking at the sight of it. I do not understand how these other reviews could be legitimate...this team was an absolute disaster and we are heartbroken. See my review on Google for photos. read more

Carroll Water did a great job, on time and on budget. A unique property built in 1943 had some challenges but Carroll's team worked with us to complete the job. We would certainly call on them again. - Essex Skypark Airport now has potable water for the first time. read more

I would not recommend these guys! They flooded my whole basement because they didn't hook up the unit right. Look for a different company or install something yourself. read more

worse service ever. They installed the water softener at my place in Ashburn which caused water leak. they dint even notice the water went all the way downstairs causing wall damage. after i informed they tried to fix it but dint turned out good after 3 visits. I hired a dry wall fix technician to fix it. They also broke the FLO device . I always turn off the FLO device by phone but never manually. They broke it by turning it manually but doesn't want to take the responsibility after lot of back and forth emails. The technicians are inexperienced. Now i asked to buy the FLO device by myself. read more

We started off requesting that Carroll water replace a valve in the past. The techs at the time warned us of the impending failure of our pressure tank. It has now failed and we called them back out to have a look at some pressure issues we were experiencing and ultimately replace the tank. James Pierce and his associate repaired the issue in under two hours and even had the tank on them when they arrived, I was impressed with the foresight. The quality surpassed my expectations and the materials used in the plumbing were changed from old junky plastic, which I am not a fan of, to stainless steel, which I love! I'm a relatively new homeowner so any repairs are going to seem expensive to me (at first) but I thought we got a pretty decent deal, paying a little over 2k. We also had a water quality check with them but I may leave a different review for that service after it has been rendered. read more

We got quotes from multiple companies for water filtering services. We've been very happy with Carroll thus far. Had a great experience with Joe and Big Red! read more

Have used this company for many years and have always been satisfied with the service. Mark our technician was prompt and answered all our questions. read more

Had to get a new well because the original well, which is only 28 feet deep, was going dry after over 100 years. They did a great job with our new well. It took a while, but that was mostly waiting on Carroll County for approval. Well digging took two days to get 300 feet, and it was hooked up another day. Very happy with the results. read more

Joe is amazing! We count on him to keep our well water perfectly filtered and softened. Joe is always available when we need him and he is very nice about answering my many questions. Thank you Carroll Watet! read more

Had some hiccups in the beginning, but they made things right. Matt T. was great and took the time to make sure our issue was resolved to our satisfaction. What else can you ask for? Got the softener system through Costco, so it came with a 10 year warranty as well. If you are in the DMV and are looking for a water softener, check it out! read more

my pressure was down to 22 PSI. I emailed Jones well drilling which they responded 10 minutes later. they came out the following Monday and replaced my well pump and wiring ($3700). the next day while showering my water dropped to 8 psi. my pressure would fluctuate between 40-8psi randomly. they returned the next day to check it out and said everything fine. I emailed back and said "but my pressure is less than before I had the pump replaced" and no response. my water is also brown now, I emailed and asked if this will go away in time. no response. they got my money so they don't care if it works right or if I have problems. I'll gladly pay another company double for my next wells issue before ever giving them a dime again read more

Our water dried up and it turned out we needed a came out and installed a new well pump for $11,000. The next day we noticed are usually very clean water looks like salad dressing. Carol water couldn't figure it out. Told me to hire a plumber and have a technician from another water treatment company flush the system. I paid to have both things done. The water still looks horrible. Carol water says it's not their fault. To prove it wasn't their fault they took a reading from the well Carroll water was supposed to send us a final reading on the water and they never did. read more
