They work differently
A furnace creates heat from its energy source, while a heat pump transfers heat. That difference affects system design and how homeowners compare the options.
The house matters
Electrical service, existing ductwork, current equipment, controls, insulation, and comfort goals all influence the practical choice.
Avoid universal answers
One system type is not automatically best for every property. A useful comparison is based on the home's conditions and the complete installation plan.
Safety note: If you smell gas, see smoke or fire, suspect carbon monoxide, or believe there is an immediate safety danger, leave the area as appropriate and contact the relevant emergency or utility service. Do not treat an active safety emergency as a routine HVAC appointment.
