A Legacy of Expertise in New Jersey Mechanical Contracting

Sunnyfield Corporation has been delivering expert HVAC, plumbing, and commercial construction services across New Jersey since 1989. The company’s story began when Nick Sapnar started working at Muirfield Co. at just 19 years old. Over the years, Nick partnered with Ed Dobson, creating Muirfield/Sunnyfield, combining decades of experience and a shared commitment to quality and reliability.

Eventually the company became Sunnyfield Corporation, a small, client-focused business that continues to uphold the same dedication to excellence. Today, Sunnyfield operates as a team of highly skilled office and contracted union workers, allowing us to deliver personalized service while handling projects ranging from $150,000 to $25 million.

At Sunnyfield, safety, quality, and client satisfaction are at the core of everything we do. As a small business, we provide the hands-on attention that larger companies can’t, ensuring every project meets our high standards and is delivered on time and on budget.

We are a union contractor certified in General Construction, Plumbing, Heating, and Air Conditioning (HVACR), LEED-certified, and experienced in historic preservation. Most of our work is as prime contractor, though we frequently collaborate with other general contractors as a subcontractor. Our clients include schools, hospitals, correctional facilities, and commercial institutions — demonstrating our ability to manage complex projects with professionalism and precision.
