Your AC compressor may be squealing due to a worn-out belt or a malfunctioning compressor. To fix it, you can try replacing the belt or having a professional inspect and repair the compressor if needed.

check a/c compressor and belt.
Yes, if the compressor's bearings are bad, usually accompanied by a roaring or squealing noise coming from the compressor's pulley.
Your air conditioner may be making a loud squealing noise because the AC compressor, which helps cool the air, could be malfunctioning. This could be causing the noise you are hearing.
your ac compressor could be seizing up. happened on my 2003 suburban.
Check for a slipping drive belt between encine crank pulley and AC compressor pulley.

Likely either the serpentine belt is squealing due to age and the extra stress put on it when the a/c compressor is activated, or the a/c compressor or it's pulley are failing.
Any of the following.......... 1. The compressor is locking up. 2. You have a bad a/c clutch. 3. You have a bad drive belt. 4. You have a bad tensioner. 5. The a/c system is overcharged.
Yes replace it using a qualified technician remember the ozone
usually those high pitch squealing sounds are cause by a loose/slipping belt. just check the tension on your belts. the ac compressor and the alternator belt. also the ac compressor belt tensioner tends too rust and also make squealing noise. wd40
