What we see in South Milwaukee homes
Much of South Milwaukee was built between the 1920s and 1960s: brick bungalows, Cape Cods, and duplexes near the lake and the old Bucyrus grounds. That means a lot of original or second-generation ductwork, 80% furnaces that were installed in the 1990s and 2000s and are now at end of life, and a fair number of hot-water boilers still running radiators.
Basements are often tight, which affects where a new furnace or condensing unit can safely vent. We know these houses because we work in them every week.
