Heat pump or furnace and AC: how to compare
What changes in your home when you switch to a heat pump, what drives operating cost, and the questions worth asking before you decide.
What each system does
A furnace burns gas to make heat, and a separate air conditioner handles cooling. A heat pump does both with one outdoor unit, moving heat into the house in winter and out of it in summer.
What changes in your home
Switching usually touches more than the equipment itself.
- Electrical panel capacity and a dedicated circuit for the outdoor unit
- Ductwork sizing, since heat pumps often need more airflow
- Outdoor unit placement, clearances, and noise near neighbors
- Removing or capping the gas line to the furnace, if you go all-electric
What drives operating cost
Cost depends on your electricity and gas rates, the efficiency of the equipment, and whether the system is sized correctly for the house. Ask for a comparison based on your home and your utility rates rather than general averages.
When dual-fuel makes sense
A dual-fuel system pairs a heat pump with a gas furnace that runs only on the coldest days. It can be a step toward electrification when the furnace is still in good condition.
Questions to ask in an assessment
- Is the system sized from a load calculation for this house?
- Does my panel have room, or is an upgrade or load management needed?
- Can my existing ducts be reused?
- What is and isn’t included in each option?
