"They care! They stopped by to address a hot water heater on the blink but the weather was brutally cold and Mikey saw me working on the boiler… After addressing a plan to convert to tankless, he helped me make the decision to switch to a tankless combi solution. Very happy how the team took the time to complete the job timely. I will use them for other projects for sure"

"Ralf and Peter provide exceptional plumbing services. They happily and intelligently answered all of my questions and concerns about our sixty year old heating system. Ralf and Peter transformed our heating system and brought all the components up to code. They also did a beautiful job of installing our new water heater. I highly recommend Ralf and Peter of Ralf Maresca Mechanical. Their pricing is reasonable and their work is outstanding."

"Service Tech Ed DeMore, who had originally installed our tankless water heater, responded and realised the unit had to be reset and recalibrated after an error message caused the unit to stop and not restart during the snowstorm of last Monday. He had us up and running in just a short amount of time. Eddie is an excellent and knowledgable employee with a great attitude. He is very pleasant and we hope A. J. Perry realises what a great asset they have in Ed."

"EVERYTHING WAS GREAT .ON TIME. WORKED WELL TO REMOVE OLD AND BRING IN NEW WATER HEATER. MY DISAPPOINTMENT WAS THE PRICE. QUOTED TO LOW. GAVE ME A 50 GAL. WHEN I REPLACED A 40 GAL. JUST SAW AN ADD FOR THE SAME TANK FOR 800.00 VS MY 1300.00 I DID NOT NEED A 50 GAL FOR ONE PERSON. 40 GAL WOULD HAVE BEEN FINE. THAT DISAPPOINTED ME A BIT. MY BILL CAME TO OVER 1900.00 VS THE 1300.00 I ANTICIPATED. HAVE OTHER CONSTRUCTION BILLS GOING ON THAT DAY. THIS WAS TOTALLY UNEXPECTED PROBLEM. BUT I AM GLAD I TOOK CARE OF IT BECAUSE I WILL BE GONE FOR 2 MONTHS IN 2 DAYS.. WOULD NOT WANT A FLOOD TO RUN BACK TOO. ALSO I AS TOLD IT WAS A 10 YEAR WARRANTY WHEN IT IS ONLY A 6 YEAR WARRANTY. I DID NOT HAVE ENOUGH TIME TO SORT ALL I NEEDED TO KNOW ABOUT A HOT WATER TANK REPLACEMENT.. MY FAULT FOR BEING IN A VERY BIG HURRY TO FIX THE PROBLEM FOR MY TENANT, I STILL FEELTHEY ARE GOOD. CALLED THEM TODAY BUT NO ANSWERE. HAD SOME QUESTIONS FOR ROLANDO. HOPE THEY CALL ME BY MONDAY."

"This was probably my best experience on Angie's List. I woke up and noticed there was no hot water in the house. Went to the basement and noticed the hot water heater was leaking. I called up Advanced Professional Plumbing, told them what was going on and gave them the specs of the hot water heater. 20 minutes later a technician showed up (a very nice guy named Joey). He inspected everything and showed us the cause of the issue. He gave us a few options on what to do and we decided to replace the 75 gallon hot water heater. Within an hour, Joey came back with Sam and they replaced the old water heater with a new one. They were both professional and got the old hot water heater without making a mess and replaced with a new one. After the job was done, Joey tested all the bathrooms out to make sure the pressure was good and we paid and they were on their way. They were fast, efficient, explained everything and it was a great price. You really can't beat that. Your hot water heater breaks down on a Saturday you are not expecting hot water for the rest of the weekend but Advanced Professional Plumbing delivered. I appreciated the office following with me to make sure everything went. Just an overall class business."

"Stephen and team did an excellent job. He called almost immediately after we submitted our request on AL and tried to help us solve our problem ourselves. When we realized we couldn't fix our issue on our own, he guided us in getting the right parts from our manufacturer for the warranty on our water heater. Installation was quick, the rate was very competitive, we really appreciated the friendly and professional service. Really responsive via text/phone, would call again!"
