Weird sound when I turn on car AC

Wadau, there’s a weird sound when I turn on the car AC. It’s just a one off sound coming from the engine bay right after I press the AC on button. After that the AC continues to function as normal. Diagnosis and solutions please?

Blower

ac loads the engine so it might grunt and shake.

Check the ac pump pulley bearing.

Is it some kinda hissing sound? Better still fafanua the sound kaka braza

Describe the sound. Could be a worn out ac compressor clutch

Service your A/C filters, check AC fan pulley, and tighten the fan v belt or replace

Service your AC by buying a new filter, checking the fan or replacing the fan pulley.For some models of vehicles , they have fan belts for the AC, tighten the belt or replace

If it’s a squeak it’s the belt or pulley
