"The Rinnai water heater was installed on 12/16 as agreed. I was absolutely amazed at the quality of the work that was done. The technicians arrived on schedule and completed the work ahead of the estimated time. They left the furnace room cleaner than when they arrived. The gas lines, air induction and venting PCV and water lines were neatly routed and installed. Everyone from the owner to his technicians were courteous and super helpful. The were expertly knowledgeable and follow through on all commitments. I could not have asked for anything more. I would categorically recommend Lorenz Plumbing ."

"My 21 year old Gas Water Heater finally has stopped working and I started getting quotes for the replacement. I contacted 4-5 companies via Angi and 3 more from Google. I texted pictures of my old Water Heater to potential contractors and had multiple phone and text conversations. Rob, the owner of R.A. Plumbing & Mechanical, offered me a competitive, but not the lowest price, but our 2 phone calls and his detailed explanation and answering my questions - that's what convinced me to give this project to him and his team. Rob explained me the difference between brands, models, and tank sizes, discussed a tankless solution, and offered to do the work on the same day, which was important for me on December 1st in Chicago. Rob emailed me the detailed estimate with a convenient way to accept it electronically and after I accepted it, he sent the team who did a great job. I highly recommend R.A. Plumbing & Mechanical and personally Rob for any plumbing projects you may have."
