Thanks AppleFritter,
Your method SHOULD work, but I am just now realizing that the  ->column_names method itself is not working for me- but using  ->print($csv_fh, $columns) does?
UPDATE: This is what I did for me to get it work, I am not sure why the column_names method isn't working for me though.. 
my $columns = [ keys $AoH_records->[0] ];
$csv->print( $csv_fh, $columns );
