AC installation cost by system.
Installed pricing for Star, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Star, Idaho, AC installation costs typically range from $3,700 to $7,300 for a like-for-like central AC replacement, while a new system with ductwork runs $5,500 to $11,900+. Ductless mini-splits and heat pumps are also common, with heat pumps priced between $4,600 and $11,000+. Because Star is in IECC zones 5-6, cold-climate sizing is essential, and many homeowners opt for dual-fuel systems to handle hard winters. Permits are required—mechanical permits must be purchased online, and a final inspection is typically needed. The federal 25C tax credit offers up to $2,000 for qualifying heat pumps and up to $600 for high-efficiency central AC, helping offset costs.

What Star code requires
Installing or replacing an HVAC system in Star follows Idaho 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—
Cold-climate sizing matters: much of Idaho is in IECC zones 5-6, so equipment must handle hard winters; permits must be purchased online and a final inspection is typically required.

What Affects AC Installation Cost in Star?
Installation costs vary based on system type (central AC, heat pump, or ductless), efficiency rating (SEER2 minimum 13.4), and whether ductwork is needed.

Choosing a dual-fuel system or higher-efficiency equipment can increase upfront cost but may qualify for federal tax credits.

Refrigerant Transition
As R-410A is phased down, new systems use R-454B or R-32. Homeowners should confirm their installer uses approved refrigerants and that the system is compatible with future service.
