I have a 1250 sq ft two story house, the upstairs is not cooling down

downstairs. It's 82f outside with 60% humidity, tstat set to 73 and my

can I
get the upstairs cooler, it stays around 78.
Thanks LW1717
Check your attic temp and if it's much warmer than outdoor ambient,
install some soffit vents and an attic fan.
An attic is always going to be much warmer than ambient in summer in full sun, seeing 30 Deg difference isn't unusual. That's what insulation is for. The attic should have adequate ventilation to keep the temperature from going to extremes and to prevent moisture. Most building experts today recommend ridge venting and not using fans.
