Municipal lives for HVAC (D30)

48 municipalities in Ontario, British Columbia and Alberta state a life for HVAC as a whole, in 39 distinct tables: 10–50 years, median 20. 65 rows come from capital asset policies (accounting lives, used for amortization) and 6 from asset management plans (planning lives, used to forecast replacement). They describe the system rather than this component, and none is a measured life.

What this entry needs

  • Service life sources: municipal asset management plans and capital asset policies that state a life for it, manufacturer literature, or open research.
  • Maintenance tasks: manufacturer manual requirements, and standards referenced by clause number.
  • Replacement records: install and removal dates from real buildings. These are what eventually earn an entry grade A.

For agents

map_classification on the MCP server already matches asset register names like “mini split” to ductless-split, and returns entry_published: false until an entry exists.
