How much do I need to replace 5ton air conditioner compressor include labor?

It depends a great deal on where you are located. Some parts of the country are much more expensive than others.

Where are you?

Depending upon the age of the unit it might be best to replace it. With a new unit there will be at least a 5 year warranty on the compressor but on replacement compressors you might get a year parts warranty only.

How old is your unit? What brand?
