What this estimate does and does not include
The calculator models energy savings using a planning install cost and local electricity rate. It does not subtract a utility program maximum automatically, because a published maximum is not the same as an approved benefit. Confirm equipment, income, contractor, application, and funding rules with the source above.
In Honolulu's warm climate, compare cooling efficiency, installer sizing, and utility requirements alongside heating savings.

How much can a heat pump save on heating in Honolulu?
There is no single city-wide savings figure. Fuel cost, electricity rate, system efficiency, climate, and the installation quote all matter. Heat pumps in warm climates also provide efficient cooling. Use the calculator with your monthly heating cost, then replace its planning assumptions with your bills and an itemized quote.
Does a heat pump in Honolulu qualify for a federal tax credit in 2026?
Do not assume it does. Current IRS guidance says the federal home-energy credits generally do not apply to qualifying property placed in service or expenditures after December 31, 2025. Check the IRS guidance and a tax professional for your project's dates.
