what is the estimated cost to replace a ac compressor. cost for part and install

a/c system needs to be repl as a complete system approx 1000.00 to get a parts warranty on compressor. you can replace compressor only at approx cost of 500.00

If there is no internal damage to the compressor and the compressor nose is/does not get damaged when removing the old clutch (bearing is part of it) or coil, then it could be as little as $200.00in parts (R-134 included)and 2-3 hours total labor Labor $ depends on the hourly rate in your area -where I'm at it's $120.00 an hour.
