ALEXANDRIA, Va. — The Air Conditioning Contractors of America (ACCA) announced the passing of ACCA past Chairman, Mike Callahan, president of Callahan Roach & Garofolo Inc. on July 26, 2022.

Callahan was an active HVACR industry champion, working both on the state and national level to fight for contractors. He, along with six other contractors in Ohio, came together to form what is now known as the Air Conditioning Contractors of Ohio (ACCO) over concerns about mechanics lien laws. He was the first elected leader of the group in 1977 and through their efforts defeated the law. On the national level, Callahan served on ACCA’s Board of Directors in the 1980s and as ACCA Chairman of the Board in 1988.

After his time on ACCA’s Board of Directors, Callahan founded Callahan Roach & Associates with Mike Hajduk and introduced the concept of flat rate pricing to the HVACR industry. Over the years this concept revolutionized how contractors sold their services and became more profitable. Along with the flat rate pricing program, Callahan was a business coach for many contracting companies across the United States.

His generosity did not end within the industry. For the past two years he volunteered for Meals-on-Wheels and the ACS's Road to Recovery, providing transportation to cancer treatment centers for patients in need.

“ACCA is saddened by the loss of such a profound member of our community,” said Barton James, ACCA president and CEO. “Mr. Callahan was a champion for contractors not only on the national level, but also on the state and local levels. He walked the walk and talked the talk when it came to fighting for what was in the best interest of contractors. Losing such a significant force leaves a hole in our industry that will not quickly be filled.”

Services for Callahan will take place on August 13, 2022 at Resurrection Cemetery in St. Petersburg, Florida. The family asks that in lieu of flowers, please consider donations in Callahan’s name to either Empath Suncoast or The James Cancer Hospital.
