I ONLY install equipment that I sell, so I can stand behind it., Water Treatment and Purification
"We got the water softener system and the RO installed by Zach from Quality Water LLC. Zach was very detailed and helpful in explaining each and everything he was doing and educating us about both the systems. I am very happy that we went with Quality water as we got quotes from other vendors like Costco and all and they were really really expensive. We are really enjoying the soft water for our house and the purified drinking water."

Water heaters, Water Purification
"Very pleased with our experience with Terry and his team...from initial phone call, through visit to provide estimate and do water test, all the way through scheduling and installation. You can easily tell that the work product and customer satisfaction matters to him and that says a lot about a company. The team was well prepared and meticulous while being efficient during the installation process, including a nice cleanup job. It looked like they were never there other than the new equipment up and running well! I made lots of calls and inquiries trying to find the right fit for our needs, and I'm very pleased with our decision to select Pure Water Pure Air. Highly recommend!"

Additions and Remodels
"Jairo and his assistant did a great job opening up the wall between our family room and living room. We were nervous about the wall since there were some HVAC ducts, but Jairo knew how best to move the duct that needed to be moved. He had to open additional drywall in the basement to access it, but he patched everything up and left it as if it had never been touched. We were very impressed by his craftsmanship and the wall opening was exactly what we wanted. We will be using him for other remodeling projects and will be recommending him to everyone we know."
