I've researched ground source heat pumps; and they only work if you've got room and a lot of extra cash up front, and live in a non-temperate climate.

In an efficiency-driven environment,National/ISO Building Codes could require their inclusion in new construction and retrofits,where applicable.They'd be embedded into the 30-year mortgage, and could be 'incentivized' by a government who's object was to get the best,lowest operating-cost technology into as many households as possible.
As of 2015,paybacks were: 4-years on a electric-resistance system replacement,
5-years for an oil-fired system,and 12-years for a natural gas unit.
If 'hidden costs' were incorporated into utility kW-h pricing,all paybacks would be accelerated.
I've got an operational,window unit that's 33-years old.I don't see any reason why the heat pump wouldn't last throughout and beyond the mortgage period,paying deep dividends long after break-even.
