Does heat pump cost cost more in Illinois?

+9% versus the national baseline

Chicago runs its own building code and licensed-trade requirements distinct from the rest of Illinois, so city and suburban pricing diverge substantially. Permit fees here run about 10% off the national average, and Homeowner permits allowed in most jurisdictions, restricted in Chicago

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.
