I've had excellent service from Dan Dunn Plumbing & Heating throughout the past year. A host of new systems were installed during an extensive renovation. New and existing equipment has also undergone regular annual maintenance. Dan and his crews are responsive, efficient, and courteous. They stand by their work and do a great job communicating with me as well as internally, to my benefit. Thank you!

Moving into our beautiful new home 22 months ago, built by Don Madore of Don Madore, LLC, was a dream come true. From the very beginning, Dan Dunn Plumbing & Heating LLC played an essential role in bringing that dream to life. Their expertise spanned the plumbing systems, furnace installation, heated flooring, ventilation connections for both the kitchen and BBQ hoods, and even the custom black gas pipe work for our lighting. I am sure they did more than listed here. They added modern elegance to the driveway gate with expertly installed wiring conduits made of matching black gas pipes to house the wiring. Even the same for the front and rear porch lighting.
At every stage, the team at Dan Dunn Plumbing & Heating LLC took the time to explain how each component worked, ensuring we understood and felt confident in the systems they put in place or repaired. Their meticulous attention to detail never wavered. Most importantly, they gave us something rare in a process as complex as building a home—peace of mind. We knew that every detail had been handled with care and precision.Their commitment did not end when the work was complete. Through ongoing preventive maintenance, their skilled technicians have kept everything running seamlessly, preserving both the comfort and functionality of our home. It is a rare pleasure to work with a company that combines technical excellence with genuine care. To the entire Dan Dunn Plumbing & Heating LLC Team—thank you for being the very best at what you do.
