A follow-up question, if I may: The system we installed in 2008 is now failing, is out of warranty, and the manufacturer just announced they are filing for bankruptcy. If I choose to replace the current equipment with new equipment, can I claim the 30% tax credit?
Yes. Repairs to the existing system are not eligible, but installation of new equipment (whether additional capacity or replacement of aging equipment) is eligible, even if you claimed the credit before on the same house.
