Limits and deadlines:

  • You can’t claim more than a $500 credit for the year.
  • Save manufacture certifications and receipts in case you need them for filing.
  • You must have installed a relevant heating and cooling system by Dec. 31, 2011.

The Energy Star site has posted new guidelines on what heating and cooling systems are covered. It’s your safest bet for information on which kinds of systems and individual products get you the credit.

Don’t rely solely on contractors who may not know the details of the energy tax credit program or who promise their products will get the credit in order to make a sale.

As of January 2012, the feds haven’t extended the energy tax credits for heating and cooling systems beyond 2011.
