What Goodman air conditioners qualify for the 2010 tax credit?

You should get your certified copy from the manufacturer and the seller of the unit saying that it is a qualified unit for the energy saver tax credit and have it in your hand when you prepare your 1040 income tax return for the year that the unit is purchased and installed in your main home in the US.

Manufacturer's Certification Statement is required for this purpose.

Go to the Goodman air condition website and see if you can find the information that you need at the website or contact the seller of the unit for it.
