"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."

"Very professional. Affordable. Zach removed my 12 year old gas hot water tank and installed a new system. He worked diligently, answered all my questions, and afterward went over everything. The work was done well, and all was left clean, and neat. Great customer service and all done the same day I called. I will definitely call this company again."

"I had A&M service my On Demand hot water heater. He did a great job. I decided to have additional work done. I have an older home and decided to have some old valves and pipes replaced. I would definitely recommend A&M"

"For years I have wanted to update my very old and inefficient American Standard cast iron boiler. I was very fortunate to find Mr Joe Burriesci the owner of Mayjac Plumbing who took the time to evaluate the best options, since the old boiler handled two apartments. We collectively decided to go with two Navien Combi Condensing Boilers, but the best part of the entire process was how meticulous the installation was done. From start to finish Mayjac Plumbing kept every promise and timeline made. I highly recommend Mayjac Plumbing..."
