AC installation cost by system.
Installed pricing for Corvallis, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Corvallis, Oregon, where the median home was built in 1979, many homes need AC installation or upgrades. Local installed costs for central AC like-for-like range from $3,900 to $7,700+, while new systems with ductwork run $5,800–$12,500+. Ductless mini-splits cost $2,900–$7,700, and heat pumps $4,800–$11,600+.

- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended

- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Oregon does not exempt like-for-like residential changeouts; a mechanical permit (plus an electrical permit for heat pumps/AC) and final inspection are required, even for owner-occupants.
