The cost to install a new AC and furnace is confirmed after an in-home evaluation because it depends on your home and the system options you choose. Most price differences come from the equipment you select, how your current setup is configured, and any upgrades needed for a clean, code-compliant installation. Our team regularly installs Carrier systems for homeowners across the Roanoke Valley. If your existing units are near end of life or repairs are stacking up, replacement is usually the better value; otherwise, a targeted repair may be reasonable. A system that’s sized correctly often outperforms an oversized unit that short-cycles.
Common factors that change price:
- Capacity and efficiency ratings (SEER2 for AC, AFUE for furnace)
- Ductwork condition, sealing, or modifications
- Electrical, refrigerant line-set, drain, or venting updates
- Add-ons like smart thermostats, zoning, or air quality upgrades
