I'm amazed by how difficult it is to get modern variable-speed heat pumps in California. You're lucky to get a two-speed unit, but they're only marginally better than single-speed. We're stuck with 80's technology because there's literally a list of what you're allowed to install. They claim it's to only allow energy efficient units, but the list is dominated by older inefficient models.

On top of that, you can't have just any contractor install it, they need to be certified to install heat pumps, and of course the ones who are certified will only install a heat pump they sell you.

If you want a modern energy efficient heat pump in California, without waiting forever and paying several times list price, you're going to have to install it illegally.

Are you in the same California that I am?

We have the same problem that the entire country has with mediocre, overpriced contractors. And we also have the same problem with ever-changing refrigerant rules. But heat pump availability seems just fine here, even for VRF systems. (Actually, VRF systems seem to be very common among new installations lately.)

you're about to be stuck with last-generation models that won't ever be updated, because the government has to renegotiate a contract with whomever and someone else will get upset and yada yada.
