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.
An AC is an “air heat pump”. The only difference between an AC and what we call a “heat pump” is a reversing valve, which can send refrigerant the other way to heat the interior instead of cooling it.
They’re literally the same thing.
A traditional air conditioner provides only cooling by moving heat out of your home, primarily contributing to summer electricity peaks. In contrast, a heat pump offers both heating and cooling by simply reversing the refrigerant flow, making it a more versatile and energy-efficient solution for year-round comfort. While heat pumps increase overall electricity demand by electrifying heating, they also shift energy consumption patterns, creating a new winter peak for the grid to manage. However, this increased electrical load presents an opportunity for demand response, allowing smart heat pumps to adjust usage during peak times to balance the grid. Ultimately, widespread heat pump adoption, powered by a decarbonising electricity supply, is crucial for reducing fossil fuel reliance and achieving a greener energy system, albeit requiring significant grid infrastructure upgrades.
