Testimonial from Carol M.

After spending a couple months doing research on different whole house water softening systems, whole house filtering systems and under the sink reverse osmosis systems, we decided to go with Mark McCoy, owner of Desert Water Services. I was really impressed with his knowledge of the subject. The system we went with which is made by a company based in Texas called Water Tech really impressed me as well. I love it all! Mark was very helpful in answering my myriad of questions as I continued with my research. He is always very responsive and very passionate about his work. I highly recommend him. The water quality we have now, verses what is was like before is night and day. He will let you know if he’s running a few minutes late, which is a rare thing these days! Everything was installed perfectly and everything completely tidy. You will not be disappointed if you decide to use Desert Water Services!

Testimonial from Lloyd Schermer

My wife and I tied our knot 69 years ago and during those years we have lived in eight homes in several cities. I was in the newspaper and TV business for 50 of those years. So, we have used the services of many plumbers.

I say with total candor, Mark is far and above the best we have ever used.

He knows what he is doing. He’s totally honest. He had some unique challenges in this old home in which we now live that he solved. We had to do some extensive fixing up and remodeling.

He also shows up when we call him for something that needs fixing PDQ.

Finally, he’s a nice guy.

Testimonial from Han Z

We recently finished out new home and wanted to invest in water treatment system. Mark was highly recommended by our Real Estate agent. The service provided by Mark throughout the whole buying process, installation, and now maintenance has been nothing short of amazing. Mark carefully provided many different plans that fit our budget. We decided to go big and it has been one of the best decisions so far as a new homeowners. Mark is super responsive to calls/text and he was able to quickly come by to make sure the system works as intended. I highly recommend using Mark!

Testimonial from J M

He went above and beyond to not only help us set up a customized house water filtration system that met my medical needs, but helped us through some other house challenges that came up unexpectedly. He’s been in this business for decades and it shows. We have trust and confidence that we have the best water system available and that his maintenance will help keep it that way.

AMAZING PRODUCTS AND SERVICE !!

Mark McCoy recently installed a reverse water osmosis system for drinking water under my kitchen sink. The water coming out of our RO dispenser is spectacular. It’s clear. The viscosity is lighter and smoother. There is no odor, taste or flavor other than just pure water like drinking out of a mountain creek. I can’t tell you how much I appreciate all the extra work he did at in order to accomplish the objectives of giving us clean, healthy water and ice. Anyone reading this review might find it interesting that 22 years ago Mark installed a whole house water softener in the house that I eventually bought. His original business sticker was still on the water softener, so I called him because I had decided to upgrade the water softener. When he came out here, he remembered at the house and the work that he had done. He’s a Get-to-it Guy and an expert. Thank you, Mark, for being professional, thorough, knowledgeable, clean and most of all honest.

Testimonial from William H

Had Mark come by my house to inspect my existing soft water and reverse osmosis systems. It turns out the systems were old and not working correctly. He also pointed out how the original install was not done correctly and displayed a vast knowledge of everything mechanical concerning a house and property. I wanted a quality product and Mark had what I was looking for. The install became difficult due to the improper original install, but Mark persevered and didn’t charge me for the extra hours required to get the job done right. Mark even installed a couple of ancillary upgrades to the homes water system at no charge. Mark is your guy! Knowledgeable, Professional, Hard working and a great guy. Plus…he gave me a great deal!

Testimonial from Dianne D

We recently had a house built in Oracle and purchased a “water treatment system” for the whole house. Spent $4000 for fresh water to come out of every faucet…H2O Concepts said no maintenance or salt needed and it was going to be awesome! 4 months later we noticed spots on everything! Our skin felt scaly and our fixtures needed the calcium scraped out on a regular basis. We called the company about it and they said that there was nothing they could do about it and that was the way the system worked. Well, we decided to bite the bullet and get a “real” water treatment system after getting ripped off from H2O Concepts. Found Mark through our plumber and he installed a new system and took the old one off our hands within days of calling him. We are so happy with our new system and how professional and prompt Mark is that we would recommend his services any day! Thank you SO much!

Testimonial from Kevin M

We were in the market for a water softener from the home. We received Mark McCoys name from our real estate agent. Mark came to the house and explained the pros and cons of the systems and did not try to oversell us on what we needed. Mark came and installed our system and the process was smooth and quick. I must say that it is working amazingly for us. We could not be happier with the service and caring Mark showed us and he also checked in with us to see how things were going a few months after installation. Thank you Mark!

Testimonial from Eve N

We just built a new Shea home in Trilogy at Verde River. Decided to wait until after close to put in a water system. We had several people come out and give us estimates with prices that ranged all over the place. Through a recommendation we contacted Desert Water Services and ultimately purchased the system through them. Mark McCoy is the owner and he did the installation. Before starting the project Mark walked through every step of the install and so we would understand exactly what he was doing and why. Mark is extremely knowledgeable, very experienced and very meticulous with his work. We did the whole home water system with reverse osmosis filtration and couldn’t be happier with choosing Desert Water Systems. 5 star service!
