Where the data plate is on a heat pump
On the outdoor unit, same place as a condenser: a plate on the side or back of the cabinet near the line set. The indoor air handler carries its own plate with its own serial.
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 Heat Pump at 10 to 15 years of expected service (nachi.org). That chart is a guideline, not a prediction for your unit.
