Apt paying for mechanicals

We own the lower apartment in a 3-family coop. We’re paying utility costs for all basement mechanicals, as well as the stoop light and 1 of 2 hall lights. There are 3 apts and 3 meters — no separate meter for these shared items. Short of instaling an additional meter (etimated at $5,000 – $10,000) how can we properly judge what we have overpaid? Previous owner repeatedly denied we were paying basement costs, but we have confirmed it with a Cn Ed inspector.
