Might cost you less to seal some windows or something than the cost of running the AC 24/7
You forget that American houses, especially lower class ones, are made out of practically cardboard or literally foam. While sealing can help a decent amount most older homes are lucky to have R10 insulation total from drywall to whatever external sheeting exists. Even now most new construction only has to be R15.
That means at best you'd be running the AC 24/7 during the summer months if you live in the 80% of the US that gets above 32c for days at a time.
To be fair, OP said their house is "old and busted". I live in a century old farm house so I know old and busted.
We run our furnace fan sometimes when it gets hot out as our dug basement stays cool so it'll blow that cold air through our house. But we have made sure to seal windows better, use black out curtains on the south side of our house (Where the sun tends to be most of the summer) and do what we can without needing to use our Heat Pump or AC units.
plant shade trees to the south and wait a few years for them to grow?
Working on it! We have a small hill on the south side that leads to our south hay field. We want to start growing stuff on that hill in the next year or two.
simple solutions are the best solutions.
keep it far enough from the house so that you don't have tree trimming issues when the tree gets big or when a storm hits..
