Commonly Asked Questions FAQ
How long do boilers last?
20-35 years. In older NYC buildings, it’s not unusual to still find cast iron boilers from the 1960s–1980s running, especially in brownstones and multifamily buildings. The issue is usually not whether they still operate — it’s efficiency, reliability, parts availability, and safety.
What shortens boiler life?
Poor water quality or untreated system water
Frequent fresh water makeup from leaks
Improper near-boiler piping
Lack of annual combustion/service
Oversized boilers short-cycling
Dirty burner operation
Chimney drafting issues
Steam systems converted improperly to hot water
Expansion tank failures causing pressure stress
