In Medford, Oregon, AC installation costs typically range from $3,900 to $12,800 depending on system type and complexity. With a median home age of 44 years, many homes require ductwork modifications or new duct systems.

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.
