Heat pump vs central AC + gas furnace

Direct answer: a heat pump can provide both cooling and heating, while a conventional split setup pairs central AC with a furnace. The better fit depends on climate, utility/fuel economics, existing infrastructure, backup-heat strategy, equipment design and the installed price of the complete proposal.

FAQ

Is a heat pump always cheaper than gas heat?

No. Climate, utility rates, equipment performance, backup heat and usage determine operating economics.

Does choosing a heat pump mean I never need backup heat?

Not necessarily. System design and climate determine whether and how supplemental or backup heat is used.
