Our History

The company was founded by Norman A. Williams in 1946 after he returned from serving in the U.S Navy during WWII. Originally known as Norman Williams Refrigeration, the company was operated as a small family-owned sales and service company for 25 years in downtown Murphysboro, Illinois. Eventually, the business changed its name to Williams Air Conditioning and Heating, Inc. (WAC).

After attending Southern Illinois University at Carbondale, Norman’s son, Ted Williams, joined the company in 1972. As the market for residential and commercial air-conditioning grew, so did the company. In 1985, the offices and sheet metal shop were relocated from downtown Murphysboro to their current locations. That same year Norman Williams retired and Ted Williams assumed the role of President and CEO.

The company experienced significant growth during the mid-1980’s and early 1990’s and, as operational space became a limiting factor to future growth, it was decided to move the residential division to a separate building. For several years, WAC operated with the separate divisions working out of different locations. In 1999, it was decided to incorporate the commercial division as a separate company, thus Heartland Mechanical Contractors, Inc. (HMC) was born.

As HMC continued to grow, Ted realized the need to narrow his focus in order to continue providing the quality of service HMC and WAC were known for. In 2005, Ted sold the residential arm of the company, WAC, so that each division could have its own team, each able to focus more directly on their customers. After a number of years of operating as completely independent companies, Williams Air Conditioning and Heating, Inc. was brought back under the wing of Heartland Mechanical Contractors and re-branded as Heartland Heating & Air Conditioning in 2013.
