MAD BOILER
Founded in 1998 by veteran technician and founder Ray Kowalski, MAD BOILER began after he was repeatedly turned away from sourcing parts for a 1960s-era steam boiler system in an historic Chicago warehouse. With no local support available, Ray spent months tracking down the exact valve components and eventually built a reputation for handling systems others considered obsolete. Today, his team continues to restore forgotten heating technologies that keep Chicago’s older neighborhoods warm.
