My own heating system is "geothermal" (GSHP - ground source heat pump), installed in 2011. The only failure thus far was the water valve (not even part of the heat pump), a couple of years in. I replaced that myself for short money, one with an improved design. Service? I slide a new air filter in now and then. Otherwise it just runs, winter and summer, and I hardly think about it.
