Many good suggestions, but I didn’t see anyone bring up how well the house is holding the temperature, aka insulation or leaks. The best AC can’t keep it cool if that cool is going outside somehow. You say the vent air feels cold so it seems to be doing its best. Single pane windows, especially facing the direct afternoon sun will be hard to keep from undoing the cooling. Attic space that has little insulation will also defeat the efforts.
Yep, always my first thought. If you’re in the US you can get tax benefits by making your home more energy efficient. It’s doable yourself but hiring someone to do it will eventually pay for itself.
And for the attic don’t just pile on insulation, need a good air sealing first if that’s no good.
This. Lack of insulation, leaky doors and windows, etc. will give your system a lot of load. My sister has no insulation and her electric bill in the summer is double mine, and I live in a bigger house.
