I think the IRS form and the energystar.gov website are not in agreement with each other. Energystar.gov says in bold letters, when you click on the "air source heat pump', "You can claim 30% of Project cost $2,000 maximum amount credited". So my $6,000 air-conditioned should have provided a tax credit on $1800, but the form limits it to $600. Another example of unclear government bureaucracy.
