The family

Stan, Mike and Danny.

Walter Kowalczyk opened the shop in 1952. His son, grandson and great-grandson still run it, from the same garage behind the same house on the South Side.

Stan Kowalczyk

Second generation · 1971

Took over from his father in 1971 and ran the shop until 2009. Now answers the Saturday phone, does the books, and gets called in for the oldest steam systems because he’s probably worked on them before.

What “and Sons” means for you

When you call, you get a Kowalczyk. When we give you a price, the person who gave it is the person who does the work, and the person whose name is on the van. Nobody is working to a sales quota.

Mon–Fri, 7 to 5. Saturdays, it’s Stan.
