Expected service life for 42 home systems benchmarked against 177 branded SKUs and 80+ material variants. Includes a 2026 replace-on-sight list (Federal Pacific panels & polybutylene plumbing) and an iframe embed widget at /embed/lifespan-database.
Why identical replacement work costs $54,990 more in Hawaii than Mississippi — labor scarcity, permitting, and material logistics.
