Absolutely not! The government extended tax credits through this year. From now until December 31, 2011 you can still claim federal tax credits when purchasing and installing a new energy efficient heating and cooling system within this year. If this is something you’re considering make sure to act soon. This will expire in December and with the economy in the state it is, we don’t anticipate this being extended. The 2011 tax credits are slightly different than the prior 2009-2010 ones. The general provision is 10% of installed cost, up to $500.
