Mine was subsidized by Ameren. They have a program where you put some money up front but the rest of the cost is paid through the savings you get by it being more efficient. They also put in more insulation in my attic.

The crazy thing is, now my wife works from home so we actually keep it more comfortable during work hours than we used to. We still saw a big decrease in electricity.

I'm hoping at some point they will have a deal for solar panels or a home battery.
