I've been in my new place for a year. I spent a few months planning. I replaced the 20+ year old A/C+furnace with a cold climate heat pump. I replaced the original aluminum clad windows and sliding doors with new Andersen ones. That alone cut the heating used by 70%! I had the loose blown attic insulation removed and added 4 inches of closed cell spray foam changing the attic to conditioned space. I changed the old gas hot water tank with a instant electric hot water unit. The attic doesn't warmer than 90 even in Arizona summers. In the past winter, it was reaching 100 in February. I updated all the electrical to meet the 2017 NEC or later swapping out every switch and receptacle. And this before I install a solar+battery system.
A lot. But the savings are a lot more than $80 per month. My summer electric bill is 75% less than my neighbors. No more gas bills. And I didn't even mention getting rid of the old bathtub surround and replacing it with a shower stall. Changing the attic to conditioned was important since that's where the indoor air handler lives.
