Hi: It was a special energy offer just in years 2009 and 2010 for windows up to $1500 credit on form 5695. We got the full credit of $1500 on this form in 2010 for purchasing $10,600 on windows.
Thanks, that was very helpful. In looking at the actual law in question (26 U.S. Code § 25C - Nonbusiness energy property) I find that for 2009 and 2010, the maximum lifetime credit was $1500. The limit dropped to $500 in 2011. The current $500 limit is not a separate limit, so since you have already exceeded the $500 limit, you aren't eligible for any credits on your new heating system.
