There is a Federal Energy Efficiency Tax Credit on Qualifying Heaters, Furnaces, and Boilers.

For 2011, the Federal Tax Credit for energy efficiency drops to 10%, up to a $500 maximum. (2010 Federal Tax Credit information)

• Oil and gas furnace and boiler incentives are $150
• Additional $50 for efficient furnace fans
• Oil furnaces, boilers, and gas boilers must be 95% efficient. (It was 90% in 2010)
• $300 cap for air conditioners
• Existing home and principal residence.   New construction and rentals do not qualify.
• Expires December 31, 2011 – Consult the What other rebates are available? below for other possible rebates.

The 2011 tax credit reverted to  2005-2008 levels. Anyone who previously took advantage of the program can’t apply for incentives that exceed $500.  IE If you claimed $500 between 2005 – 2008 on a previous energy efficiency project, or at least $500 tax credit from 2009 – 2010, you are ineligible for the 2011 energy efficiency tax credit.

If you used say $200 of the $500 energy efficiency tax credit from 2005 – 2008, and did not utilize the 2009 – 2010 energy efficiency tax credit, you would still have a $300 credit available.

AFUE >= 95% to qualify for the tax credit. Oil Furnaces and as, Propane, or Oil Hot Water Boiler must have AFUE >= 95%. Not all ENERGY STAR products will qualify for the tax credit.
