Fan coil unit
Also called FCU, fan coil
Service life
Years in service. One stated life so far; the band will widen as sources are added.
One source. This value rests on a single document (CNA e-Tool Estimated Useful Life Table, p12). Treat it as that source's figure, not a settled life, until others confirm it.
Basis
- 30 years · CNA e-Tool Estimated Useful Life Table, p12 · HUD CNA 3.4.2.2.11 “Fan Coil Unit, Hydronic” — U.S. Department of Housing and Urban Development (planning life)Same life for family and elderly properties. US multifamily housing. HUD's row is for hydronic fan coil units.

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.
Years. Each dot is one stated life and each bar a stated range; equal values stack. Hollow marks are planning lives from asset management plans; filled marks are accounting lives from policies. The dashed line is the median. Policies that copy the same table count once.

Open questions
- Only one source so far, HUD's 30 years for hydronic fan coil units, and other published tables commonly give fan coils shorter lives. HUD's single row does not separate the coil and cabinet, which can last decades, from the fan motor, valves and controls, which usually do not. A second openly licensed source is needed before relying on 30 years.
- Only one source so far: HUD planning lives for US multifamily housing. Canadian and observed sources are needed.
- Furnace tasks come from Army TM 5-642 (1990); equipment and practice may have changed since.
