I'm in FL and have had heat pump cooling since 1992. It's the usual AC system here for, well, at least since the 1990s, if a house has 'central AC' that's a heat pump. There is no other sort of central AC I am aware of. It's not new technology, I am confused?
People usually talk about "heat pumps" when they're talking about using those systems to heat homes (and sometimes heating water), not cool homes. When they talk about the devices that cool homes, they generally just call it AC (even if it is technically a heat pump).
We as a country use far, far more energy heating homes than cooling homes.
The difference is that a heat pump is a two-in-one unit, so it's basically an air conditioner with a reverse switch.
