"Brian responded promptly, was professional and courteous. He came right away to do an assessment and returned within a few days to install a new water softener system. He presented me with a lower cost option that could have been done same day but I chose to replace a 17 year old system with a new system that is more accurate (better monitors water use) and less costly to operate because it uses less salt. He performed several preventative maintenance updates: re-piped and plumbed in a new particulate cartridge, cleaned the screen on the radon system and replaced the solenoids, all within the cost of what other companies quoted for only the water softener replacement. The last technician that serviced our water systems (Radon & RO) rushed through the job and left them in worse shape than they were before he "serviced" them. Brian recognized the issues and fixed them. I will now be using H20inthe603 for all of my water treatment service. Thank you Brian for a job well done!"

"I contacted Proactive to replace my water heater because my current oil system a 5 yr old system kept flooding my basement. The tech looked at the system and spent about two hours on his phone reviewing the system. finally he figured out that my return temp was set too low and was automatically expelling the hot water on the ground outside my water tank. I was elated. So many times I called plumbers and the oil company who swapped tanks and switches , costing me several thousands of dollars. when he left he didn't want to charge me even a hundred bucks, the time he spent researching the problem. I tipped him big time. He was worth it. He saved me from unnecessarily buying a multi thousand dollar new system, and he ended the constant and expensive flooding in my basement. Yes, if necessary, I will use Proactive Comfort again!"

"I had my full home repiped as I switched from electric to forced hot water heating. Fred was courteous, communicative, and timely in making the repairs. We ran into quite a few snafus and he took them in stride. His quote was MUCH lower (about half the price) of the original quote we got. Definitely recommend."

"George and his team did an excellent job with the install. I received quotes that were much higher for the same project and similar systems. As busy as George was he always answered my questions leading up to the install and was there right when he said he would be. George even helped me plumb a water line to my refrigerator and didn't charge me for the material he used! I have already recommended Absolute Water Systems to a friend and will certainly be using them for any future projects."

"Mitchell was very professional and great at the work he’s done on my 2 homes. I’ve had 2 bathroom remodels. Funace and hot water heater replaced. Put an expansion water tank on one of my homes. Hooked up my water for my new refrigerator and dishwasher. Have not had any issues with his work. Highly recommend."
