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 unit

get the upstairs cooler, it stays around 78.
Thanks LW1717


Hot air rises and the upstairs will always be warmer. If you have poor
attic insulation, you'll be fighting a losing battle. Otherwise, close
most vents which lead to the downstairs and basement(if applicable).
Closing the vents to the other areas of the house will force more cool
air upward. I also suggest sealing all duct seams, if it's not already
done.

Ensure the vents are not covered upstairs. Clear any furniture and
clutter which may be blocking airflow.

Consider using a vent fan, box fan or ceiling fan to draw out the air.
