On: Heat pumps slash emissions even if powered by a dirty grid

The lifespan of a heat pump and a furnace is similar

My HVAC guy likes heat pumps, but he thinks their lifespan is about 1/2 or 2/3 the life of an HVAC unit; the equipment is the same (pumps, motors, etc), but the heat pump runs nonstop year-round. He still prefers heat pumps, since they're all electric, and can be solar powered (I'm in Texas); so, the combination makes a lot more sense, in the long-run.

My anecdotal observations from service providers in the space:

No. That’s very much not the case in practice… Not in the case of family homes and nonlinear demand, that is.

What breaks?

[rrr_oh_man → voisin]

Heat pumps, no matter the manufacturer, (anecdotally) seem to break within 1-5 years at a rate not comparable with oil or gas furnaces.

Most manufacturers offer 10 year warranties

1-5 years is ridiculous.

Lennox advertises that a heat pump lifespan is equivalent to an AC, which is 12 years vs 20 years for a furnace.
