Does it pump heat variably in both directions?
Most ACs are reverse cycle these days since it's a very minimal extra cost to allow it to both heat and cool - it just needs a four-way reversing valve. There's no point making it only cool when you can instead make it both heat and cool for a similar price.
The USA is weird though. Companies still make units that only cool, and strangely there's a big price difference between cooling-only systems vs reverse cycle systems. I haven't seen this in other countries.
Because heat pumps are popular now, and the government is helping people pay for them through inflation reduction act rebates. So they can jack up the price and price gouge the shit out of us, because they know they can and know that they will get away with it. And I bet they were never popular because the same people selling home AC units also sell gas powered furnaces for home heating. So they charge you for two appliances and two installations, with two maintenance calls every time something goes wrong and two upgrade cycles. But now that they come as one unit, they still have to find some way to return more money to shareholders than last quarter so the price goes up.
I just got whole home AC replaced with a heat pump with an integrated furnace backup because it can get very cold here, and also had all my baseboard heaters ripped out. Perfectly fine in the winter and it has freed up at least 1/4 of all my walls to have stuff right up against them if I so choose, but really annoyed that the whole thing costed $20k when it could and should have been built this way 60 years ago. Not to mention all the inefficiency of burning gas for heat when heat pumps move more energy than they consume, multiplied across decades for nearly every building on the planet.
