There was an interesting article on heat pumps in the NY Times yesterday - they are similar to AC units but far more efficient, requiring far less electricity to run. Plus they work as heaters in the winter. I use heat pumps coupled to solar panels and draw very little power from the grid, if any.
Ya, Im very confused when people talk about heat pumps as separate from ACs. My new tenant got super excited when I used the word "heat pump" to refer to my AC.
