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

Good afternoon.

It may be as simple as low Freon but needs to be confirmed. You need a set of gauges to read the high and low side pressures to be sure.

Do you have gauges? The readings would be very helpful for me to help you get the correct information.
