A company from Oyster Bay, NY - Oyster Bay, NY

"From replacement cost estimation to cleaning working space, in the end, everything was done in a fast, professional, courteous manner, the service was impeccably brisk. I got cost estimation from a few companies, O'Brien's price is very competitive. Great customer service, attentive to details and very friendly. From the beginning, it was a huge project. Not only old heater had to be broken up to pieces, because stairwell to the basement is very narrow, and replaced by the new one the team had to remove and reinstall my existing water tank because it was blocking the way. Everything was done in one day! By 6:30 pm I have heat and hot water in the house! Special thanks to Justin and his team. Hard work, ability to solve problems, great spirit!"
