It may be something as simple as a loose cabinet which can be repaired by tightening a couple of screws, but more likely the problem is something internal. The motor mount may be loose, the blower could be out of balance, or there could be a problem with the bearings. If the rattling comes from the outside unit, it may be a problem with the fan or the compressor. Most of these problems will require the skills of an HVAC professional.
