"Neo was excellent! My water heater went and a new one was installed by Neo and his team the next day. They were very professional, communicated instantly, and did a fantastic job. Will definitely use S.S Piping n Heat for all of my future plumbing and heating needs. Would recommend this company to anyone!"

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"JT called and asked if he could come earlier than expected, which was perfect for me. He was extremely thorough reviewing our electrical system and the finished product of the work he did (installing a new 220v line for an outdoor hot tub) was clean and efficient. He was a joy to meet and speak to, incredibly nice guy. Price was reasonable for the work. I would 100% recommend JT and Cotti-Johnson again!"

"By the time I found Joe’s business, the water heater had been deemed dead’s by the manufacturer, it was Sunday afternoon, a blizzard was to start around 8:00pm. Joe and his partner took out the old heater, drove with me to HD picked up the new one, installed it and I had hot water before the first snow flakes hit the ground. The price was very reasonable too, regardless of the circumstances. Two thumbs up and five stars."

"Addario's Services did a great job installing a new high efficiency combo boiler in our home. After I requested an estimate, I got a quick call from the office to schedule a time for one of their comfort advisors to come out to our home. Sam, my comfort advisor was very knowledgeable, and I appreciated his low pressure presentation. Once the work was booked, because our installation was complex, Joe came out and came up with a plan to vent the exhaust on the side of my house to minimize the number of pipes on the front of my house. The installation went very well, and they installed a temporary water heater so we were only without hot water for less than a day. For the day we were without heat, they brought in plenty of space heaters to make us comfortable for that night. When the installation was complete, the installation technicians took lots of time to explain the operation of the new system, and to answer any questions I had. The system is working great and there have b"
