Switch all traditional AC to being powered by Heat Pumps, destroy all private jets, ban recreational flights and power AI responsibly or not at all.

Switch all traditional AC to being powered by Heat Pumps

Aren't traditional AC's (assuming you are somewhere where AC is a thing used to cool the air) already heat pumps?

In my attempt at brevity, I articulated myself wrong, totally my bad. I would like the old school systems replaced with either air source heat pumps or ground source heat pumps, backed up with on-site solar and batteries. Modern heat pump systems can heat and cool and are much more efficient than AC as generally installed.

The efficiency gains from an air source heat pumps are on the heating cycle, not the cooling cycle, since you are moving heat around instead of having to generate heat via combustion or big heating elements. When acting as an air conditioner, the efficiency is the same.

Ground source heat pumps (GSHPs) are generally the most efficient, achieving 350-500% efficiency by leveraging stable underground temperatures, though they have higher installation costs. Air source heat pumps (ASHPs) are also highly efficient at 250-400%, extracting heat from the air, but their performance can be affected by extreme outdoor temperatures. In contrast, a traditional gas boiler for heating is around 90-95% efficient, while separate air conditioning units cool, but neither offers the combined, high-efficiency performance of a heat pump. Therefore, for overall energy savings and reduced environmental impact, heat pumps are the superior choice for both heating and cooling.
