That's great, it pencils out for you financially. It doesn't for us.
In San Diego, we run the AC about 6-8 weeks per year. We run the heat about 10 weeks per year. Rest of the time we might turn on the whole-house fan to pull some air through and provide a breeze, but that's it. The "payback" period because of the short utilization is very long for Heat Pumps. I'll do it when our HVAC units die, but they are only 6 years old, so it's going to be a while. We have over-provisioned solar so that we can run the AC whenever we want (from our powerwalls directly, this isn't a net-metering swap, we touch the grid for less than 500 kWh per year).
Our gas usage for the stove and hot water (tankless) heater are so small ($10/mo) that replacing either of them will NEVER, not in 30 years, not at 5X the current gas prices, pay for itself. Labor and appliances are expensive here (as in most of Cali), it's a large hurdle to jump to make it pencil out, especially when we are already in a new house with all new appliances (we couldn't pick them, they were already picked before we found the house or we would have put in much less natural gas stuff). If I was getting back some of my taxes for this rebate, I would do it. But it looks like they are going to exclude high-income earners in this move. That's not surprising given the political optics.
I'm 100% behind being environmentally friendly, but I won't do it when it doesn't pencil out financially. Otherwise you are just giving a blank check to the equipment manufacturers and installers.
