"We have used Quality Water on two different occasions. Zach on the first appointment and Timothy on the second. They both were very professional, knowledgeable, and courteous. They both explained how our water treatment system works and didn't try and push other things that we didn't need. My wife and I learned more from them, then we did from the company who installed it 15 years a go. We highly recommend this company. Thanks again for the great service."

"Excellent service! They were able to come out the day I called to evaluate our well that evening. They were able to a**** the problem and detect exactly what the root cause instead of masking it with a water filtration system as another professional had recommended. Dexter's plumbing went above & beyond helping us and we greatly appreciate it. We highly recommend them."

"Our 40 year old furnace went out during a cold snap this spring and Moises was able to replace our whole system with a Trane dual fuel furnace system that works with our solar and gas as well as new AC unit. We were delighted by the significantly reduced power consumption this summer on AC down from $500 to $75 a month! The whole system cost us about half of what my co-worker paid for theirs. Moises and his crew were timely, professional and kind. Later this summer, my Ecobee for controlling my mom's HAVC system went out and Moises was there within two hours to fix it. I wholeheartedly recommend Tyler, Moises and crew. I have known Tyler and Moises for years and their integrity, honesty and work ethic are exceptional. This is the trusted team I welcome into my home and fully recommend"

"They were very prompt and courteous. They were very efficient and had our water heater and water pressure values replaced with less than hour of work. Best of all , the cost was 60% less than the amount the large A/c and Plumbing company was going to charge us."

"WT was great! Diagnosed the problem pretty quickly and fixed the issue of water pressure. Went an extra step and took samples of water. Great to have an experienced friendly person come out on a Friday afternoon which was less than 24 hours from my call."
