ASHRAE is the industry organization that sets the standards and guidelines for most HVAC-R equipment. They have published a chart that lists estimated life expectancy for various HVAC equipment.
Below you can see ASHRAE chart of HVAC Equipment Life Expectancy. The chart includes a list of median life expectancy for the following types of equipment:
