| Central AC + Gas Furnace | $5,000–$12,000 | Cold climates with existing ductwork |
| Heat Pump (Air Source) | $4,500–$10,000 | Mixed climates, max efficiency |
| Dual-Fuel Heat Pump | $6,000–$13,000 | Regions with cold winters + high AC demand |
| Ductless Mini-Split | $3,000–$9,000 | Additions, no ductwork, zoned comfort |
| Geothermal Heat Pump | $15,000–$30,000 | Maximum long-term efficiency; verify current incentive rules |
