Try using the SubTotals feature on the Data menu.
Your data will have to be sorted so that identical months are in adjacent rows.

I have a very large database of monthly meter readings. Some months have
multiple readings, which throws me off for using pivot table. Is there a way
to filter the table in a way that adds the values for repetitive months?
