GraybealHeating and A/C Service was opened in 1957 by brothers, Herman and Lloyd Graybeal. Both had been employees of Missoula Hardware and Plumbing. When that business closed, they formed a business that still runs strong, all these years later.

In 1986, then employee, Rick Cannon, became the new owner when Herman retired. Rick had attended the MT Vo-Tec in Billings and trained under the Graybeal leadership after graduation.

Rick's son, Vance, is a strong part of the business. He has been in charge of the construction and installation portion of the business for over 15 years.
