David did great, professional work, communicated with us clearly along the way, and paid extra attention to details like cleaning up dust and testing for leaks. The team solved our pretty major plumbing issue in 2 days, replacing a number of old, leaky pipes (or badly installed ones) with new PVCs. Would recommend to all!

Ledi was very efficient and worked so quickly. Him and his team so professional. They completed the job in my home in less than 3 days. They stayed past their working hours to make sure I had my heat running in my home. 10/10 definitely recommend

Just had another great McMahon experience, having my heating problem resolved by Ledi. Troubleshooting, parts retrieval and installation all on Friday afternoon. Been withMcMahon for about 40 years, always pleased with results.

I highly recommend McMahon Plumbing & Heating, who provided a great customer experience from the beginning to the end.They installed heat pumps in our house, which included 2 outdoor condensers and 6 head units inside, as well as replaced our water heater with a new hybrid heat pump electric tank, and installed 2 electric base boards.The quality of the equipment and parts used, as well as the craftsmanship of their technicians and electricians was superb. Everything is amazing and of top quality, from the actual condensers and head units, to the pipes, wires, thermostats, etc etc. It's all of great quality!!We weren't sure how it would end up looking with all these pipes running along the outside walls of our house. But they did such a great job of blending and hiding everything to fit in and match the design of our house. I think our house looks even better since it is now updated with all this great technology and top quality equipment. And like I said, it was their top priority to make everything blend in and match the design of our house.Even before they began, they were very thorough when drawing up the diagram of our house and the work to be done, which included 30+ pages of a proposal, which included pictures and floor plans, and was very easy to follow, and they explained everything step by step.And when they first arrived, John, who was our head technician, walked through and explained the location of everything that was going to be installed both inside and outside. The head electrician, Eric, also did the same with all the electric work he was going to do. And they wanted to make sure I was 100% happy with everything. And they answered all my questions, throughout the whole install, and addressed all my concerns, and made all the custom modifications that I requested.I could honestly write so many more good things about the entire experience, even with how friendly they were with any questions I had after the work was done. I hope if you are considering any plumbing or heating work to be done at your house, to trust me when I say, this company is definitely worth your consideration. You will be very happy with your choice.

Water heater went so I called. They promptly sent 2 technicians, David and JDL who arrived on time and were friendly. They diagnosed the problem and clearly explained my options. They immediately went to work and had my water heater replaced in hours. I was expecting to wait days while they ordered one, etc. They both worked hard and quickly and worked through lunch to finish so I could get to work. Delightful guys. Very knowledgeable . Couldn’t be happier with the whole experience!!

Adam at McMahon Plumbing and Heating is absolutely fantastic! He did an amazing job replacing our corroded first-floor pipe that was causing a backup. Adam was incredibly polite and professional, always addressing me as "Sir." His work was efficient and he kept me informed every step of the way. We initially hoped for a simple cleaning to save some money, but Adam was honest and upfront about the pipe's condition. The replacement with PVC pipe was done perfectly, and we couldn't be happier with the results. If you need plumbing or heating services, look no further than McMahon Plumbing and Heating! We have used McMahon on another project as well and we plan to utilize their service for an evaporator coil box cleaning for the central AC as well. A++
