Having LI Clean Water Service, Inc. install clean water... into my home has been a dream come true. We had the installation done about a month ago and it's the best thing we could have done. My skin and hair have seriously improved. This water is medicine for your health. I am pleased with the service. Anthony came to our home and he was such a delight in showing and explaining the facets of the quality of our water. He took us down the yellow brick road and we were excited to plan the next step which was the installation. When James and Reynaldo came to install the filtration system, we knew we hit Emerald City. Both technicians are fabulous. They really care about their work and about Clean Water. I felt confident about the whole process. It was really hot that day and they persevered. Afterwards there was a small issue under the sink but it was because of the humidity and I got nervous.. well Justin came the next day to check it out and everything was fine. Talk about family caring, well LI Clean Water definitely proved that. I wouldn't recommend anyone else. LI Clean Water Service is top notch in my book. Even the cats love the clean water, their water fountains stay cleaner because of it.read more

Mark recently serviced my water filter for an annual... replacement filter. He was efficient, knowledgeable and friendly and did a great job! My only negative comment (hence 4 stars, not 5) has nothing to do with Mark, but with the way that service appointments work at LI Filter. When my filter stopped working and I called for an appointment, they only offered a window of 9-3. One can call the morning of the appointment to narrow it down to maybe a 3 hour window, but that is often too late to fix my schedule. This was fine during Covid-times when I was home all the time, but is very inconvenient now that I am out working and busy. I wish appointments could be set up in a more customer-friendly manner. Otherwise, LI Filter is great. I am happy with the filter and with the service.read more

Many residents in our town have recommended LICWS Inc...we... are beyond happy with the product. We had the entire house serviced and the results are beyond my expectations. The plants are even thankful... Highly recommend it. We had a slight innocent install issue which could have caused other issues. They immediately took action to mitigate the situation and took the right measures to support the customer. Drinking 8oz of water daily is a non issue. My husband is also happy that the recycle bins are less full. Jay is great!read more

Have been very satisfied with the service and security in... knowing the water I drink is being filtered with reverse osmosis, particularly as a lung cancer survivor. The two service technicians who just replaced the filters and did an annual maintenance on the units for me and my daughters fridge’s were both neat, professional and prompt.read more

Excellent Service and Product. I hated drinking water due... to the taste of some water. This water tastes like nothing making it very easy to drink. System works great. Less hardness and i can tell from my showers to my coffee machines. The deliveries for salt come even when i forget. Every time a delivery with salt arrives they fill the salt, check the equipment and do a water test. So happy I converted my house to this.read more

Long Island Clean Water is an excellent business. I have... been a very satisfied client for several years. The office staff is friendly, helpful and knowledgeable. This past visit with Mark and Paul went very well, they called in advance of their visit, remembered I like the bleach tab, tested the Ph of the water, made adjustments so the water flowed more quickly from the spigot and cleaned up thoroughly after themselves. i would recommend LICW to anymore looking for a superior water filtration system. Most importantly the water tastes great!!read more
