Located in Greenfield, Ohio Weller’s Plumbing & Heating was established in 1943 by Charles Weller. In 1979, the business was purchased by John Weller and Stephen Hunter and was incorporated in 1982. Over the years, the company has grown substantially - starting out as a local heating and plumbing company with a small retail supply store and now, today one of the largest and most competitive mechanical contracting companies in Southern Ohio.
