Our Company History

Carl M. Lieber was born in October of 1894. After working for Hanson Brothers Plumbing in Oklahoma City for a number of years, he ventured out on his own and began Lieber Plumbing, Heating and Air Conditioning in 1949. He operated his company out of his residence and garage at 1010 W. Park Place in Oklahoma City until he was 81 years old.

Carl Lieber's original HVAC repair trust, a reliable 1949 Dodge.

In 1972, Carl’s son-in-law, William E. “Bill” Carroll, joined the business. A year later, Bill’s 14 year old son, Craig, began helping his father.

Craig learned the trades working weekends, summers and holidays through high school and then college. He obtained his Journeyman Plumber’s license, Natural Gas Fitter’s license, Mechanical Contractor’s License and Refrigeration license.

After graduating from the University of Oklahoma with a Bachelor’s of Science Degree in Construction Management in 1983, Craig went to work full time in the family business. He continued with Lieber Plumbing, Heating and Air Conditioning for another five years after graduation. At that time, being more interested in new construction, Craig left the family business to work for larger mechanical contractors.

Bill Carroll carried on Carl Lieber’s tradition and continued operating the business until he was 79 years old. In 2008, Craig Carroll decided to rejoin and rebuild the family business with a new company name of Lieber Mechanical LLC. The name changed, but the company continued to operate in a way that honored the legacy of the Lieber name… a foundation built on our F.O.U.R. Core Values … Family, Opportunity, United and Respect.

Craig, like his grandfather, began working out of his home with a 1,200 square foot shop. He quickly outgrew this and in two years, relocated to a 6,000 square foot office/warehouse at 9700 NW 6th Street in Oklahoma City.

In July of 2012, Craig acquired his current location, a 7,000 square foot office/warehouse, at 1105 First Place Blvd in Yukon, OK. He recently added on another 5,000 square foot warehouse and acquired 2 additional acres of adjacent land for future growth.

Craig Carroll is the owner and operator of Lieber Mechanical.
