Disclaimer

The data, calculators and comparisons on HeatSwap are provided for general informational purposes only. They are estimates of heating energy cost, not a quote, a guarantee of savings, or a professional engineering or energy-audit analysis.

Actual heating costs and heat-pump savings depend on factors this site cannot know: your home's insulation, air sealing, windows and size; the specific equipment, its sizing and controls; how you set your thermostat; the actual severity of the winter; and your specific utility's rates, fees and tariff structure. Our seasonal COP and AFUE figures are documented assumptions, and our fuel prices are statewide or regional averages from the EIA that change over time.

Before replacing a heating system or relying on any number here, consult a licensed HVAC professional, get a Manual J load calculation and quotes, and verify current prices and available rebates with your utility, your state energy office and the relevant federal programs.

HeatSwap accepts no responsibility for any loss or decision arising from reliance on the site. See our methodology for sources and limitations.
