"I moved into my new home on 7/8 and knew I needed to replace the 20 year old hot water heater. The water was warm in the shower and brown. Originally, I planned on getting a tankless unit, but that was prohibitively expensive and not allowed in my community. Taking the next prudent steps, I secured my three estimates. Not only was AquaFlow the least expensive, but when I met Enrique, I knew I wanted to work with him on this project and all future plumbing issues. He explained what needed to be done, secured the tank from the supply dealer, and showed up at 9:00 AM promptly as promised. It was originally planned to be a two man job, but the other person couldn’t make it. Enrique did the entire job on his own. I was amazed. He worked until 5:00 PM. I asked why he didn’t just reschedule with me, but he stuck to the date and time he gave me. He also installed my new touch-less faucet and adjusted the cartridge in the shower and I now can take hot (not warm) showers."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."
