AC on, I get a hot air at the beginning

When I start the engine and turn the AC on, I get a hot air at the beginning until I drive the car then it starts cooling, but the cooling also is not that good with 90 degree outside.
This issue happens specifically in summer with the hot weather.
at night or around 75 degree the cooling you feel it better.

I changed the in cabin filter with new one but still the problem exist.

Kindly advise.

Thank you
