Quick answer
A heat pump can replace the heating role of a furnace in many homes, but climate, low-temperature capacity, ductwork, electrical service and existing fuel infrastructure determine whether heat-pump-only, dual-fuel or furnace + AC is the better comparison.
Where a heat pump, furnace or dual-fuel system fits
Compare system paths against the house you already have. Existing ducts, gas service, electrical capacity, climate and the need for cold-weather backup can make heat-pump-only, dual-fuel and furnace + AC materially different projects.
Dual Fuel HVAC System
Compare system paths against the house you already have. Existing ducts, gas service, electrical capacity, climate and the need for cold-weather backup can make heat-pump-only, dual-fuel and furnace + AC materially different projects.
At what temperature is a heat pump useless
Compare system paths against the house you already have. Existing ducts, gas service, electrical capacity, climate and the need for cold-weather backup can make heat-pump-only, dual-fuel and furnace + AC materially different projects.

How the HouseIt tool makes this more specific
The tool asks only for facts that can change the branch or result. Unknown answers stay unknown, and the result should become more cautious rather than inventing precision.
Safety and limitations
Do not open electrical or combustion compartments, bypass safety controls or handle refrigerants based on an online check.
