A/C only cool properly at high RPM's

Greetings..I am new to this site and is the proud owner of three Riviera's. I own two 95's and a 98..all supercharged.
One of the 95 and the 98 do not cool properly while idle. Your suggestions and or experiences are appreciated.

Look into automatically adjusting orifice tubes. They make the A/C perform better at low speeds/idle by stabilizing the balance between high/low pressure more efficiently. Rockauto sells them for the Riviera.
