"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."

"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..."

"This was the second time using South Shore Plumbing & Heating they installed a tankless water heater for me in March. 2020 and today Nick located and fixed a pin hole pipe leak under my house cement slab. From the time Nick started to make his first cut in my Sheetrock he used a level to make sure he was cutting a straight line ( thatâ s a professional who take pride in his work) when he drilled to open up my slab he made a small hole that was right where the pipe leak was. Cut out the bad pipe and installed new section of pipe no leaks and Nick re- cemented the hole closed and clean up all the debris. Anyone who needs excellent plumbing or heating call South Shore Plumbing and Heating ."

"Mr. Vitola  was a pleasure to do business with from the point we met to discuss estimates until the job was completed.  He gave me all the information I needed to make an informed decision and took time to answer all questions in a timely fashion.  His crew is knowledgeable, hard working, and professional.  I can honestly say that if you do business with APV, you will do so with confidence and peace of mind.  I would gladly do business with APV again and highly recommend.

"Heater was making a knocking sound and of course it was the holiday season. Braido came out right away and found a fan part needed replacement. The parts vendor was closed but they came out the next available day and had everything running smooth."
