Overall it was a great experience, there were some minor issues immediately after installation that got dealt with quickly and efficiently. I think the list price was similar to what you were quoted, but in northern california (menlo park, peninsula clean energy) there were around $5000 of grants/tax incentives, and an interest free loan from pce for the rest, over 5 years meaning our monthly repayment should be about equal to the reduction in our gas bill.
We already had solar and batteries, otherwise I would NOT want to put myself at the mercy of PGE and their crazy electricity rates. But as they reduce the payment rates for solar electricity, the heat pump becomes a better deal.
