AC installation cost by system.
Installed pricing for Cornelius, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Cornelius, Oregon, a typical central AC like-for-like replacement runs $3,600–$7,200+, while a new system with ductwork costs $5,400–$11,700+. Ductless mini-splits range $2,700–$7,200, and heat pumps $4,500–$10,800+. Oregon requires a mechanical permit for all AC installations, even like-for-like changeouts, plus an electrical permit for heat pumps or AC units. With a median home age of 39 years, many homes may need ductwork upgrades or load calculations. Given the mild marine climate and moderate cooling demand, a heat pump is often a strong fit, especially with the federal 25C tax credit (30%, up to $2,000 for qualifying heat pumps, $600 for high-efficiency central AC).

What Cornelius code requires
Installing or replacing an HVAC system in Cornelius follows Oregon rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- 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.
