The formula
Net cost = (tons x cost per ton x efficiency) + permit − tax credit; Payback = net cost / annual savings
The federal 25C credit covers 30% of qualifying heat pump costs up to $2,000 per year. Savings depend on what you are replacing — the swing is largest when displacing electric resistance heat.
