Frank Lacny grew up working in his dad’s gas station. As automobiles began debuting air conditioning units, his dad sent him off to school to learn how to fix them.
From there, Lacny attended an HVACR trade school.
After graduating, he spent time working at a refrigeration company, which merged with a large boiler/burner company in Chicago. There, Lacny gained experience working on burners and large industrial boilers. Several years later, in 1984, he elected to start his own company, American Combustion Service Inc. (ACSI).
