Furnace and AC Unit - Residential Energy Tax Credit

[Mcb050032]

Need help confirming if the following Model numbers qualify for the residential energy tax credit, these were installed last year.

Furnace: American Standard S8X2D120M5PSCA

AC Unit: Bosch B64-392 BOVB-36HDN1-M18M

Based on searching I believe the AC unit tax credit is only available for "South Territories" and not north.

The furnace I believe is eligible based on the CEE directory list. Is the max credit $600 for each?

Thanks in advance.
