Get matched with top tankless water heater repair pros in Ossining, NY

"Aldo was great. Communicated about when he expected to be there. Was polite and prepared with mask etc to enter the house. Found that he was able to simply repair my valve rather than go through the expensive process of replacing. Impressed with his professionalism and honesty. Would definitely recommend him."

"Anji recommended four plumbers. Cassidy was the first to respond on Friday afternoon. One other plumber responded but I could not understand his heavy accent, and he asked me if I wanted him to replace the whole burner assembly. That made no sense to me and I questioned him about it. Suddenly he became "too busy" and hung up the phone. Another plumber didn't respond until Monday morning. Too late. The fourth plumber never responded at all. Cassidy asked if it was an emergency or could wait until Monday. I said Monday. and asked what time? I did not get an answer on Friday. Around 8:30P I called and got an answering service which told me that I wouldn't get a response until Monday because their office closed at 8:00P. I had asked about what time on Monday before 6:00P George arrived Monday morning. He was friendly. He knew what he was doing. He replaced the thermocouple. All work was done neatly and professionally. We have hot water again. I'd use Cassidy again."

"Bob and Tom are great contractors. They not only did an awesome job replacing my water heater, they also identified issues in my chimney while they were connecting the vent pipe for the water heater. I will hire them again for separate HVAC projects."

"Wilson was extremely professional. He came to my condo to make repairs to two toilets. Wilson did a great job. He explained what needed repair, showed me the parts he replaced and cleaned up after himself. I would definitely hire him again."

The final cost was exactly as stated, with no hidden or additional fees. I was very happy with the quality of their work, and would recommend them to anyone."

"I recently had Nick out to fix my oil burner, and I couldn’t be happier with the experience. My heating system suddenly stopped working properly during a cold snap, leaving us without heat. From the first call, the team was responsive, professional, and got someone out quickly. Nick arrived on time, was polite, knowledgeable, and took the time to thoroughly diagnose the issue. He explained everything clearly, what was wrong, why it happened, and what needed to be done without any upsell pressure or confusing language. The repair was done efficiently and cleanly; he left the area spotless, which I really appreciated. My oil burner is now running better than ever. Heat is consistent, and I feel much more confident going into the rest of the cold weather. Honest, skilled work at a fair price."

"Dave worked with us on annual maintenance and some repairs on our oil boiler. Recently moved in and the prior owner did not maintain the system. They did a thorough inspection and clean and it's running great now. Ended up with a few part repairs needed which were thoroughly explained and fixed quickly. Will be coming back to again, and found Dave to be trustworthy and thoughtful."

"John and Jason were perfect! They’ve done amazing work to my new homes 2 full bathrooms. It’s hard to find reliable & professional work these days. These guys deserve this review and then some!"

"I utilized Flo techs, many years ago. They serviced my old hot water heater. They were able to solve the problem at the time. I called them recently for a free estimate. The company does not seem to offer this service any longer."
