AC installation cost by system.
Installed pricing for Augusta, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Augusta, Maine, AC installation costs vary with system type and home age. A like-for-like central AC replacement typically runs $3,100–$6,100, while a new system with ductwork can cost $4,600–$9,900+. Ductless mini-splits range $2,300–$6,100, and heat pumps $3,800–$9,200+. Given Augusta's cold climate and median home age of 63 years, a dual-fuel system (heat pump paired with a furnace) is often recommended for efficient heating and cooling. Permits are required, and a Master Mechanical Tradesperson must apply. The federal 25C tax credit offers up to $2,000 for qualifying heat pumps and $600 for high-efficiency central AC, though homeowners should verify current availability.

Recommended unit for Augusta
Given Maine’s cold climate and mixed heating, dual-fuel (cold-climate heat pump + gas furnace) is the sensible default for most Augusta homes. The cooling season is short, so the budget is better spent on heating efficiency than on ultra-high SEER2. A pro can confirm the right size and system for your home with a load calculation.

What Augusta code requires
Installing or replacing an HVAC system in Augusta follows Maine 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: Maine winters require heat pumps rated for low-temperature performance (HSPF2/cold-climate spec), and permits/licensing vary by town with a Master Mechanical Tradesperson required as permit applicant.
