Hum inspect the fans. If it still sounds wrong let the techs check it out.

There are 2 fans an Aux and a main. The AC will turn on one of them. The Aux normally is on the pass side and it helps cool the AT tranny cooler if present.

They should be somewhat loud. Louder than the engine probably at idle,
