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.
No online serial lookup was found for Napoleon in our research. The manufacturer's customer service line, the installer's invoice, or a printed date on the plate are the remaining authorities.
What we could not confirm
- The era not stated format has no source we could check; it is shown for completeness only.
- The era not stated format is documented but not decodable here: no pattern (no date encoded, or format unknown).
- No official online lookup URL was verified for Napoleon.
- No building-center page (404 for /napoleon/, /napoleon-hvac/, /napoleon-hvac-age/) and napoleon.com returns 403 to curl. UNSOURCED - no rule.
