I had my AC compressor removed and replaced with a dummy pulley about a year ago. The reason was I had a long trip ahead of me and the compressor was making some funny noises, as if she was about to blow. I'd like to go ahead and put in a new compressor and have the system re-charged, however I'd like to make sure I don't set my new compressor up for failure. I am passingly familiar with the need to replace additional components in the system after a bad compressor, i.e. some sort of filter, as well as the need to flush the system, in order to remove foreign debris that will damage the new compressor.
I would like to know a few things:
1. Is it legal for a DIYer to attempt this sort of repair? 2. What are all of the components that need to be replaced to prevent problems down the line? 3. Can I complete the repair myself, or do I need a professional to perform the actual recharge of the system?
I am quite adept at automotive repairs, and don't mind attempting one that is a little more involved. I currently live in the Detroit metropolitan area, though I will be moving to the DC metro area shortly, if there any difference in legality between the two locations. The lines were capped when the dummy pulley was installed.
