"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"They were quick to answer our inquiry and quick to schedule an appointment, quick to provide a proposal and after being hired they were quick to start and finish the installation. Very professional, easy to work with and a very high quality installation."

"Prompt, efficient service --- Technically knows gas furnace products --- More importantly knows the economics of keeping up with repairs on a 30 year old unit vs going with a new unit --- Not a sales pitch -- just facts ---- Went new and the cost including nicely done installing was much lower than I originally thought it would be .

"E-mailed for a quote inquiry for boiler install. Received a call and a visit same day. Ron fit us in for a combi boiler install within a week as we lost hot water. Roy and Austin were true professionals. Very knowledgeable, thorough and neat. A solid company that genuinely cares for its customers. Ron and crew... thank you for everything. You're all top notch guys. We're looking forward to our new mini split ."

"Very professional and diligent with the installation of our new heating and hot water system. We could not be happier with how we were treated by all we came in contact with at Onofreo."

"Technician arrived on time for appointment. Greg was wonderful!!!! Explained his process and patiently answered all my questions. Excited to have local business to maintain our boiler services."

"Excellent workmanship and very pleased with results. Heating and a/c also done with very efficient operation."

"I really enjoyed having the work done by East Coast. They were professional, and when I had questions, they took the time to answer them, even if it meant calling in someone else, or coming by on another day to demonstrate some of the features of the system. In my book, East Coast goes above and beyond the contract to really provide customer satisfaction."

"They did an exceptional job with installing my new warm air system. Would highly recommend!"

"It got done, unfortunately required a full system replacement."
