The federal tax credit is not through Harmon Electric, and we do not guarantee any certain tax credit. You should consult your tax accountant if you have detailed or specific questions about your situation.
In general, though, you can receive a 30% tax credit on geothermal heat pumps. This means that 30% of the cost of the system can be used as a tax credit to pay your federal taxes. This is in addition to the Harmon Electric Rebates.
Cost of system * 30% = Federal Tax Credit
Cost of system = $20,000
$20,000 * 30% = $6,000 Tax Credit
