How Old Is My Heat Pump?
Heat pumps use the same serial codes as the same brand's air conditioners. Pick the brand and type the serial number from the outdoor unit to see when it was made and how much of a typical 10 to 15 year life is left.

The brand on the cabinet is not always the company that made it. Who makes what.
Where the serial number is
On the outdoor unit, look for the data plate on a side panel, usually near the electrical box. Heat pumps and air conditioners look alike; the model number or the plate will say "heat pump".
How long does a heat pump last?
Most heat pumps last 10 to 15 years. Yearly servicing, the local climate and how hard it works all move it within that range. Past 10 years, it is worth getting a replacement price before the unit fails, so you aren't forced into a rushed decision.
Heat pumps made before 2010 almost always use R-22. What that means.
