Heat Pump vs. Furnace (2026): Cost, Lifespan & Which to Choose
Both systems keep a home warm, but they do it very differently: a heat pump moves existing heat (and reverses to cool in summer), while a furnace generates heat by burning fuel or using electric resistance. The right pick hinges mostly on your climate and local energy prices — in mild regions a heat pump can do both jobs efficiently; in harsh, sub-freezing winters a furnace's raw heating power is hard to beat.
Side-by-side comparison
| Factor | Heat pump | Furnace |
|---|---|---|
| Upfront cost (installed) | $10,000 – $25,000+ (incl. cooling) | $3,500 – $7,500+ (with ducts) |
| Lifespan | 10 – 15 years | 15 – 30 years |
| Efficiency | Up to ~3× heat per unit of electricity (mild weather) | Gas 80–98.5% AFUE, steady in any cold |
| Heating + cooling | Both, year-round | Heating only (needs separate AC) |
| Cold-weather output | Drops in deep cold; cold-climate models to ~-13°F | Full output even sub-zero |
| Fuel source | Electricity only | Gas, propane, oil, or electric |
| Best for | Mild/southern climates; one system for both | Cold/northern climates, long winters |
Figures are typical national ranges — your numbers depend on your home and local market.
Pros & cons
Heat pump
Pros
- Heats and cools with one system
- Very efficient in moderate climates
- No on-site combustion or CO risk
- Runs on electricity (pairs with solar/clean grid)
Cons
- High whole-system upfront cost
- Efficiency and output drop in extreme cold
- Shorter 10–15 year lifespan
- May need backup heat in very cold regions
Furnace
Pros
- Lower upfront cost with existing ducts
- Strong, fast heat in any weather
- Long 15–30 year lifespan
- Natural gas is often the cheapest heat
Cons
- Heating only — needs a separate AC
- Combustion needs venting and carries CO risk
- Electric and propane units are costly to run
- Gas units need more maintenance
How to choose
In mild or moderate climates, a heat pump usually wins because it covers heating and cooling in one efficient system. In cold northern climates with sub-zero winters, a natural-gas furnace (paired with AC) typically delivers cheaper, more reliable heat. Compare your local electricity and gas rates, and factor in rebates and tax credits before deciding.

Frequently asked questions
Standard models lose efficiency as temperatures drop, but cold-climate heat pumps can operate to roughly -13°F; very cold regions often add backup heat.
In mild climates a heat pump often costs less to run than any furnace; where natural gas is cheap and winters are harsh, a gas furnace can be cheaper.
No — a furnace only heats, so cooling needs a separate air conditioner, whereas a heat pump does both.
