Company Background

Ralph's Heating & Cooling is a 3rd generation, family-owned and operated company founded by Ralph J. Heritage in 1945. The company was established with the intentions of operating a business of honesty and customer appreciation.  These are characteristics which we still adhere to today 70 years later.

In the 1970’s Ralph and his wife Jody had stepped aside and their children Robert (Bob) and Carol Jean had taken over full operations. In 2002, Ralph's grandsons Joseph and John assumed full operations of the company where they still remain today.
