No service life yet. No published source that meets our sourcing policy states a life for this component, so we give none rather than guess. The maintenance tasks below are sourced. Know a public-domain or openly licensed source? Send it to [email protected].

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.

Open questions

  • No service life yet: no published source that meets the sourcing policy states one. The maintenance tasks are sourced.
  • Written for GSA contracted O&M in US federal buildings; job plans are generic and defer to manufacturer instructions, and the fire extinguisher plans only point to NFPA 10.
