Where the data plate is on an air conditioner
On the outdoor condenser: a metal or foil plate on the side or back of the cabinet, often near the refrigerant line connections. Some brands repeat it inside the electrical access panel.
General guidance, not brand-specific: the owner's manual or the installer can point to the exact spot. See the data plate guide.
For scale only: the InterNACHI Standard Estimated Life Expectancy Chart for Homes lists Air Conditioner (central) at 7 to 15 years of expected service (nachi.org). That chart is a guideline, not a prediction for your unit.

This site is a reference built from published tables. The manufacturer's own lookup wins whenever the two disagree.
