For equipment installed between January 1, 2011 and December 31, 2011, the following tax credits are available:

• High efficiency furnaces and boilers – $150
• Air Conditioners and heat pumps – $300
• Main air circulating fans – $50
• Energy efficient water heaters – $300

The $500 cap will apply to anyone who received the credit from Jan. 1, 2005 to present. Thus if you’ve claimed a cumulative credit of $500 or more of the tax credit since Jan. 1, 2005, you won’t be eligible for the 2011 extension. If you’ve claimed less than $500, you are eligible for the difference with qualifying equipment.
