Boiler & Radiant Heat in St. Louis: what's different
Boiler & Radiant Heat in St. Louis is shaped by local conditions. Older boilers: Boilers need annual service.
Brick rowhouses and two-family flats are common, often with boilers or older furnaces. Mini-splits are a popular cooling upgrade. Many St. Louis homes are brick two-family flats and single-family houses from the late 1800s to the 1940s, often with basement furnaces or boilers. Central AC is common in post-war homes, but older homes frequently rely on mini-splits or window units. Older chimneys may need liners when switching to a new furnace or water heater. For boiler & Radiant Heat, that means the contractor should start with system check and confirm what is actually installed before quoting. Another local pattern worth mentioning to the tech: historic brick homes. Thick walls and plaster make ductless systems practical.
The City of St. Louis Building Division issues mechanical permits in the city, and St. Louis County and its municipalities handle their own. Schedule furnace or boiler service in fall and AC service in spring.
