Went for a callback install. Upon arrival customer stated that unit was vibrating. After inspection found inner casing around condenser fan blades misshaped and blades hitting the side. Took too off and listened mountainside mg screws then reformed plastic away from fan. Tightened everything back and remounted too. Started unit and allowed to run with no further issues. Also found too cap vibrating so put foam tape on underside of cap to help with vibration. System operational upon departure.
