I'm in Texas, and my HVAC guys all switched to heat pumps on their own houses a few years ago. The main problem is that most of are on electric AC and gas/propane heat; so, the switch to heat pump usually means throwing out either a perfectly good AC or a perfectly good heater, and installing a heat pump which is, generally about 50% more expensive than either: it's just a lot for a homeowner to swallow. For new builds, the entrenched builders have backlogs of old equipment that they don't want to lose capital on. It's a tough cycle to break.
