Dunphy Plumbing & Heating

I had an excellent experience with Dunphy Plumbing and Heating and highly recommend them. They installed my new under-warranty electric hybrid water heater and made the entire process incredibly easy from start to finish. They handled everything — ordering the water heater, scheduling the installation, and hauling away the old unit. The communication was excellent throughout the process, and I really appreciated how tech-savvy they are with messaging and payments, which made everything simple and convenient. On the day of the installation, they worked efficiently and professionally. They completed the job in only about 2.5 hours and were so respectful of my home that I hardly even knew they were there. Another thing that stood out was how quickly they were able to help. I reached out on

We had a great experience with Dunphy Plumbing & Heating in South Dennis. Bill took care of our tankless water heater, handled some outdoor plumbing issues, and gave us clear advice on what to plan for down the line. It’s hard to find tradespeople this reliable on Cape Cod. We’ll definitely call him again for any future plumbing or heating needs.

Bill helped us when our gas furnace failed. He was able to come over and diagnosed the problem and gave us our options. We decided to go with a new furnace and matching a/c system. Bill placed the order and was able to have it installed in a week. Bill is an outstanding at his craft and ability to plan ahead for unexpected issues. We will use Bill if and when we need a five star plumber/gas fitter in the future. I would highly recommend Bill Dunphy Plumbing. Dennis Chatham
