Heat Pump vs. Central AC and Furnace
A heat pump works like an air conditioner that can run in reverse, so one system handles both cooling and heating. A traditional setup uses an AC for cooling and a separate furnace for heat.
Cost comparison
| System | Typical cost | What it covers |
|---|---|---|
| Heat pump | $4,200–$7,600 | Installed |
| Central AC | $3,900–$7,900 | Installed |
| Gas or oil furnace | $3,800–$10,000 | Installed |
| Electric furnace | $1,700–$7,100 | Installed |
| Furnace and AC with ductwork | $8,500–$19,200 | Project total |

How they compare
| Heat pump | AC + furnace | |
|---|---|---|
| Equipment | One outdoor unit plus an indoor air handler | Outdoor AC plus indoor furnace |
| Heating fuel | Electricity | Gas, oil, propane or electric |
| Cold climates | Cold-climate models heat well below freezing; many homes keep backup heat | Furnace output does not drop in the cold |
| Operating cost | Depends on local electricity prices; usually efficient in mild and moderate climates | Depends on local gas or oil prices |
| Dual-fuel option | Can pair with a gas furnace that takes over in very cold weather |
Which fits your home
- Heat pump: mild to moderate winters, no gas service, high gas prices, or you are replacing an AC and an electric furnace anyway.
- AC + gas furnace: very cold winters with affordable gas, or a furnace that is still in good shape.
- Dual fuel: cold climates where you want heat pump efficiency most of the year with gas backup.
Ask about current federal, state and utility rebates before you buy; programs change often. ENERGY STAR has a rebate finder by ZIP code.
Get the sizing right
Whichever you choose, ask for a load calculation (often called a Manual J) rather than matching the size of the old unit. See what an HVAC quote should include.
