ATG came through! I hired them to redo a faulty, unsafe and also incomplete Navien Boiler installation. ATG Mechanical is licensed, experienced, and trained to install Navien Boilers and are listed on the Navien boiler website as certified. Victor came to review the incorrect installation from a previous unlicensed and inexperienced company and then organized a list of supplies and game plan of how they would redo the faulty work with a reasonable estimate. They were able to get me hot water after 23 days of not having hot water in about 6 hours! The difference between their work and the previous incorrect installation is shocking! I will never work with another plumbing company ever again... ATG is my go to from now on!!!

ATG is the company to choose for all your plumbing needs. My mother and I have been having issues with our brand new Navien combi-boiler units since 2016. The original plumber and follow-up plumbers did not install/pipe the units correctly which led to so many heat and hot water issues. We would have saved ourselves from so much lost time, money, and sleepless nights if ATG installed the units for us from the very beginning. This year, we decided enough was enough. We researched Navien and their website provided a list of Service Specialists. We placed our trust in ATG to install brand new Navien units and repipe the entire system. Andreas and his crew are the best. They are all skilled plumbers, trained Navien service specialists and professional. The two units were completed in 2 days. On the 2nd day of work, they were also able to fix 5 leaks in the house as well. You will not regret hiring ATG for your plumbing job. They will do the contracted work the right way, the first time. We will be lifetime customers. Andreas you can never retire! Shout out to his exemplary crew C, S, and V~

I cannot say enough good things about this company. Andreas, was very professional, very responsive to my calls/texts, and he really did such an amazing job. After hurricane Ida, Queens was destroyed with flooding in basements and first floors. My entire basement was flooded and it destroyed my washer, dryer hot water heater and of course, my boiler. Andreas managed to not only find me a boiler in record time when everyone was trying to find one and be put on a wait list, but he also came the day after it arrived to install. He made sure everything was wired correctly and that all was working properly and safe. Many people take advantage of other during times like these, but he was so kind and so helpful throughout this whole process. I cant thank him enough for all his hard work and I will look forward to working with him in the future! Thank you!

I have had the privilege of having Andreas and his team of certified and trained assistants take care of my plumbing and heating needs for many years. I haven't used anybody else for over 20 years nor would I. When you have the best nothing else will do. ATG has replaced water heaters, removed asbestos from my basement, replaced and upgraded all of the pipes in my basement, handled all my bathroom plumbing issues and provided me with new plumbing for a completely gutted kitchen renovation and I must be forgetting some other things they’ve done for me. My house was built in 1941 and ATG has provided my house with state of the art parts and technology. These guys are super professional, courteous and clean workers. They have always answered my calls and have super competitive pricing and have never left me hanging or unsatisfied with their work. I wish I had carpenters and electricians I could rely on like ATG.

Its been almost 1 month since ATG installed a new Navien boiler in my house. I'm not someone who goes out of there way and right a review. I have to now, because there work has been exceptional. Andrias, was very attentive to my needs and fair towards my price point for the job. This is the first part of the review, and will write a second during the winter months when heat is really needed. But currently the work I seen so far im very impressed and would recommend this company.

They did a terrific job installing our new tankless water heater. Most plumbers are not knowledgeable in these systems, but Andreas and his team are trained and certified. The project required drilling through the house to vent properly, and Anthony really made an extra effort to do the job correctly and not damage our house. We really appreciate it!
