We have several estimates on AC and furnace replacement. One of the contractor mentioned the tax credit. He said we need to make sure the combination of AC, Coil, and furnace is active in ARI database in order to get the tax credit on central AC in CEE tier 2 group (15 SEER).

Besides tax credit purpose, do I need to check ARI to make sure the contractor use the right combination of AC and furnace?

Thanks.
