Problem

My A/C is buzzing very loudly outside.

Possible Cause:

This is almost always the contactor. The contactor is a relay that turns off and on a compressor. If it's buzzing loudly that means that something is stuck in the contractor or the contactor itself has failed. Because this is 220v we recommend a professional work on it.
