House insulation.
I live in Australia where the minimum insulation required by law is a long way below inadequate, and many cheap contractors go below the minimum because it's so hard to prosecute them.
I already had solar and a house battery, so the next obvious step was replacing the insulation. With my already very low electricity bills I cant say that it literally paid for itself (although it would have without the solar and battery), but it has made the house so much more comfortable. On some summer days, the AC would be using 7kW and barely keeping the inside temperature down to 30°C/85°F. Now it uses 3-5kW and the whole house stays comfortable.
Also, finding and patching the massive gaps from the previous "landlord special" house extension made a huge difference to the temperature of that room, and explained how lizards had managed to get inside.
