      T.F. O'Brien replaced my hot water heater with a new heat pump hot water heater. Their staff was clean, courteous and professional. I'm very pleased with the work.

      The team was professional and responsive. They managed to remove a huge nearly 100 year old furnace from our home, install a new furnace, and clean up all in about 5 hours. When we had an issue after, my email was responded to quickly and a technician came first thing the next morning to resolve the issue. I’d highly recommend this company!

      Response from the owner

      Jay, thank you for writing this review and for recommending us! We hope you're enjoying your new furnace now.

      TF O’Brien is amazing to work with because their service is professional, friendly, and seamless from start to finish. We wanted a second zone installed in our attic, which we knew would be a costly and invasive job. Brendan Sihler (who handles sales and is overall awesome) was on time for our consult, thorough, and patient in answering all our questions and concerns from pricing options and understanding how the system would work to transparent questions about how messy the job would be. He was also great about correspondence for further questions and helped us find a pricing package that matched our needs with our budget. When Andre and his team came to do the work, they were on time every day, very friendly, tolerant of our very barky dog (ha), and extremely clean and conscientious considering how invasive the job was. I had proactively covered all of our upstairs bedroom furniture with plastic sheeting so as not to get dust and plaster all over them, but the guys still did an extra layer, covering everything from the doorway to the stairs and cleaned up at the end of each day. We’ve had other contractors in our home to do other jobs, and no one else was as neat as they were. It really was such a great help not having to do major clean up at the end of each day and they even finished ahead of schedule. The work itself was neat and seamless as if the system and all the vents and the return had always been there. We are very pleased and are glad we chose to work with them. Would recommend them to everyone hands down.
