I have been a customer for many years. We believe the water purification is good for our health. Michael Kreiser is a trusted professional who quickly diagnosed the problem and made the repair to our system efficiently. His fast response is always greatly appreciated.

Michael Kreiser and his team did an excellent job with the installation a few years ago. They did an amazing job, work was done fast, clean, professionally and on time. Michael keeps a calendar of the next appointment to have the filters changed so I don’t have to worry about it. I definitely recommend Michael and his product and services.

Michael Kreiser is a man of his word. He calls before he arrives for the appointment, does his work efficiently and professionally, discusses what was done and takes time to answer any questions or concerns one may have. He wants to provide his customers with the best and most appropriate water treatment systems available and is up to date on current and upcoming technologies in order to do so. I trust him and his ability to keep my water as pure as possible and as a result my health as I live on property that was planted with tobacco for years and treated with chemicals that can probably still be detected in the soil. My water source is a well. Mr. Kreiser is honest and forthcoming about his systems. I never worry about anything he’s recommended in the past or present.

I was very hesitant. The only review available online was bad but there were several good ones on home advisor. So I took a chance and I'm glad I did. Replaced our softener, UV light, and particle filter for less than others quoted for just the softener. Went from quote to installed in less than a week. Clean, professional, and even nice enough to haul our old stuff up from the basement and out to the driveway. Thank you!!

We learned that there had been inadequate installation of our filter and that we had been overcharged for several years on unnecessary, expensive equipment. Found a reputable local water treatment system installer to properly configure and maintain our system.

Mike came out on a Saturday, spent about 2 hrs explaining our water, the science behind what we would be getting, how the system would work and helped find a system that would fit our home and water consumption. He then returned the same week to install our unit and again made sure we had all the information and education we would need to take care of our unit to guarantee our investment lasts.

Mr. Keiser called me on a Sunday evening shortly after my inquiry. He was polite and informative. He was available for the initial appointment in 3 days and had the job done 4 days later. He and his helpers were all very nice, polite, and punctual. They cleaned up afterward beautifully. Mr. Keiser is very knowledgeable, and it is important to him that you get exactly what you want and need. I cannot recommend him highly enough. I only wish he could handle all of my homeownership needs!

Very knowledgeable and thorough in regards to our water treatment system. Mike was able to answer all our questions and kind enough to explain how everything worked and what we should be looking for if an issue were to arise as this was an already existing system installed by the previous home owner. I would highly recommend Micheal Kreiser water systems for all your water needs. Very reasonably priced as well!

Michael was prompt with responding & squeezed us in early morning. Diagnosed the issue & got straight to work in replacing a worn down malfunctioning water softener. Very reasonable and a great guy overall. Definitely would recommend.
