Charged $100.00 because the Copeland junk only has a 1 year warranty. Made in China like everything else, no doubt.

Point of information. Compressors in Condensing units carry a five year warranty. Replacement compressor has a one year with an optional four year coverage pro rated. R410 A systems with 13 seer have a ten year warranty.  :)

1.What high side low side pressures is the compressor running?
2. Some compressor noises can be remedied with isolation pads installed.
3. You might try evacuating the system check the orifuce for an obstruction and recharge.
4. Do a acid test to see if the system is contaminated.

From HVACRInfo site on scroll compressors:
Loud, very loud, relief sound coming from the compressor.

Some model scrolls have an internal pressure relief (IPR) valve. This valve opens at a discharge to suction differential of 375 to 450 psi (R-22) or 550 to 625 psi (R-410A). Check for restrictions in the discharge line, overcharge of refrigerant or a faulty component.

I think what you need is someone who knows what they are doing. Not "Bevis and Butthead".  O0

If the unit is still operating but noisy have you tried adding compressor oil?
