How long do ground-source heat pumps last?

The ground loop piping is designed to last for up to 50 years or more. The indoor heat-pump unit has a life expectancy of around 20 years, similar to conventional heating and cooling systems. Some pumps, controls, or other components may require replacement sooner than the indoor unit.
