The link above for the 2007 ASHRAE Applications Handbook, HVAC Applications seems to be broken.

Does anyone have information on how to determine the service life of a piece of HVAC equipment?

Thank You,
Evan

For anyone else who is wondering, I found my answer on pages 310/ 311 of the LEED v2009 Reference Guide.
