Growing up, my Dad had a someone for just about every issue that life could throw at him. Car’s making a funny sound? “Call Mr. Genese.” No hot water? “Call Mr. Martin.” Need a sport coat for my first job interview, “Call Mr. Antista.” Those people cared about my Dad and his family, they did great work, and most important, their advice could be trusted. Yellow Dog is bringing back old school customer service, with plumbers and HVAC technicians who are highly technically competent, and more important, who really care about your family and can be trusted to give you the best advice.

"Mike did two major projects on our home and we will hire him again without hesitation. One of our projects was particularly complex: converting a cinder block and steel structure into a studio an auxiliary space. We had incomplete and impossible architectural plans, but he was able to find workarounds to these shortcomings. He was always available for questions and we enjoyed working with all of his subcontractors. He also did a remodel of our kitchen, including taking down a wall. The result is perfect and he did the work quickly and without any issues. We get so many compliments on both projects. We also love working with Mike."

We work with some of the best tradesmen in the industry to deliver a quality finished product. From deck and porch builds to siding and windows, we can do it all. Contact us for an estimate on your project today! Check out our instagram for photos and updates @coenconstruction

"I recently hired Coen Brothers Construction on a thorough bathroom renovation, and the outcome was outstanding. Their quality was excellent, and I am delighted with the final result. Their sub-contractors were also great and worked at the same high standards as the Coen Brothers. Although we faced some communication issues at the outset, we eventually worked through them, and it significantly improved throughout the project. They paid attention to detail; when my project manager saw me stripping the trim for reuse, they recommended buying new trim and a lumber yard to get it. And it makes a big difference having new trim with clean, sharp lines. Their tile work took longer than expected, but the miter cuts the trim cuts, and the finish is excellent. They were consistently punctual, respectful of my home, and very tidy - tidying up at the end of each day. While the project took longer than anticipated, the reasonable cost and the team's meticulous attention to detail compensated for it. Coen Brothers Construction also expertly handled all necessary permits and inspections, keeping me informed every step of the way. Overall, I am satisfied with their work and would hire them again for my next project."

FAQs for tankless water heater installation projects in South-Weymouth, MA

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
