Default Ac cooling intermittanly

2005 Lexus RX330
Front wheel drive
No tow package
Florida
Ac works sometime and then after driving a while warms up.
I can hear the compressor coming on
Both fans come on when the auto button is pushed.
Freon is good.

From the 05 RX330 Service Manual....
The best option would be to inspect refrigerant pressure with a Manifold Gauge Set to compare readings.

How do you know the refrigerant is "good"?
