EXCELLENT Based on 37 reviews Posted on Google Michael SolomonTrustindex verifies that the original source of the review is Google. Mark is a true master of his craft. The customer service, product quality, and competitive pricing Desert Water Services provides is top tier!Posted on Google Kim BostonTrustindex verifies that the original source of the review is Google. We were fortunate to meet Mark of Desert Water Services through our builder. Since our home was under construction Mark had the added issue of coordinating with the project management team and plumber. Mark really went out of his way to install the soft water system parts at the right time to get us the very best outcome. He added a water filtration system to complete the job and we couldn't be happier with the outcome. Our first day in the new home he even came out to help us with an issue related to the contractor accidentally turning off our water to the dishwasher. We are so pleased and grateful to have met Mark! The whole system is wonderful and we have already referred friends to him. We had our first service appointment after purchasing our systems. Mark continues to offer the very highest quality service. We're so pleased with our systems!Posted on Google Sherry LeaTrustindex verifies that the original source of the review is Google. Mark rebuilt my home water treatment system five years ago which saved me many $$$. Mark works conscientiously with attention to detail. I was shocked to see he polished my water softener on the outside to make it look new. I also had him install a reverse osmosis system under my kitchen sink which he did neatly, this allows me to utilize the space underneath effectively. I can recommend Mark's work confidently.Posted on Google Gary ThomasTrustindex verifies that the original source of the review is Google. It was a pleasure working with Mark to install our RO and water treatment system at our house. I received quotes from four different vendors, and the prices varied greatly. One vendor didn’t even bother to visit the site to discuss it with me. We chose Desert Water Service because it offered the best value. During Mark’s visit, we discussed what we needed in a system. He provided several options and explained the maintenance and future costs associated with each. He clearly aimed to engineer a solution that met our needs, rather than just selling a pre-made kit like the others seemed to do. He arrived on time, did professional work, left the work site spotless, and followed up in the following days to ensure everything was functioning as expected. I highly recommend Desert Water Services based on the quality of their work for our purchase.Posted on Google robert weathersTrustindex verifies that the original source of the review is Google. Mark is a wealth of water knowledge! He just designed and installed a water system with softening, RO ice and RO drinking water for us. It is fantastic to not have to buy and lug home heavy flats of spring water anymore. It’s some of the best tasting water I’ve ever had. I cannot recommend Mark and Desert Water Services highly enough. Thank you Mark!Posted on Google AmyTrustindex verifies that the original source of the review is Google. On recommendation of a well specialist I purchased a spin filter that ‘cleans itself’ for our well water. It didn’t. Within a few months it was clogged beyond what frequent manual cleaning would improve. Consulted with several plumbers who in turn consulted with water specialists - the solutions were wide ranging and all cost prohibitive. Van Marke plumbing supply has provided great customer service so I called to gain insight into what I really needed that wouldn’t break the bank. “If we have water quality questions we call Desert Water Services. Nice guy, knowledgeable, good prices”. So I called DWS, owner Mark McCoy arranged to meet me that afternoon (👍🏻). That visit was a cursory assessment for him but I learned exactly the information I’d been seeking for a year. Once he had reviewed our well water quality results we discussed filtration options. The system was installed within two weeks (!). Filtration units are well protected and the system actually looks great - very professional. Could not be more pleased with the outcome. Quality of workmanship: outstanding. Cost: very reasonable. Satisfied ?: extremely Recommend DWS without reservation.Posted on Google Mary DuerksenTrustindex verifies that the original source of the review is Google. It was a pleasure to work with Mark. He understood my concerns and provided me with the best possible equipment solution. There was never any pressure to purchase unnecessary products. Mark was detailed in the install, explained the process at a highly professional level. He was mindful of my property and after the clean up it was like he was never there. I highly recommend Mark to everyone residential or commercial.Posted on Google George SharpTrustindex verifies that the original source of the review is Google. Couldn’t ask for a more knowledgeable and professional person than Mark- his installation of the equipment and cleanup was something you don’t often see anymore and he didn’t leave until he was certain we understood the workings of the new equipmentPosted on Google james nesciTrustindex verifies that the original source of the review is Google. I've known Mark for years. He's done plenty of work at my home and he recently installed a new whole house water softener. The installation was quick, neat and economical. His attention to detail is great (that's why I use no one else) and we've never had softer water. He knows what he's doing and he takes care of his customers. Thanks Mark!Posted on Google Carol NavarretteTrustindex verifies that the original source of the review is Google. I have known Mark since 1995 when he installed my first water softener. Loved it. We moved in 2003 and had him install the reionator once again. We have been pleased with his service and honesty. He loves this product and stands behind it.
