Yes, you would be able to divide the total cost of the HVAC system that you installed by three to use that number to enter in the tax return. The HE Furnace is probably the most expensive of the three components followed by the AC Unit. You could divide the total cost and place more of the dollar amounts for those two items. Just make sure that the total equals the total on the invoice.
