Grumpy, are you staying warm?

Our home was built in 2016. We upgraded nearly everything to increase efficiency. We heat/cool about 3000 sq/ft.

We put a new furnace in 2007 and it was considered a high efficiency unit for the time.
The air conditioning unit was new a year before we bought the house in 1998.
Both units would be higher efficiency is we would replace them.
Our house is 1,100 sg/ft plus the basement so we heat and cool 2,200 sq/ft.

Our previous house was built in 1973 and it is 1200 sq feet on a crawl. We moved into our current house in 2008. The house was new in 2008 and is a 3000 sq feet ranch on a full unfinished basement.
The cost to heat and cool the new house was actually less than it was to heat and cool our previous house. More efficient heating and cooling equipment along with more efficient building material made the difference.

I have thought about adding a whole house generator but have not pursued it seriously at this point in time.
