Founded in 1945 by Frank Mallek, Tri-City was purchased by Denis and Carole Virnig in 1974. Denis and Carole owned Tri-City Refrigeration since 1974, over half of Tri-City's life.

Since Denis' passing in late 2009, two of their three children, who grew up in the business, now operate the business. Andrea (Virnig) Jensen is President and General Manager, Scott Virnig is Vice-President and Senior Service Technician and Sue (Virnig) Lockman also works for the company and is Construction Coordinator.

Tri-City Refrigeration has earned Women-Owned Business Enterprise (WBE) Distinction with the State of Wisconsin! Tri-City Refrigeration has received certification as a Women-Owned Business (WBE) through the State of Wisconsin Department of Commerce. This designation is pursuant to the state administrative rule requirements of Comm 104 which provides validation that we meet the requirements of being at least 51% women-owned, controlled and managed. This qualifies us to be considered for contracts with corporations and government entities that seek vendor relationships with businesses owned and operated by women.
