AC installation cost by system.
Installed pricing for Columbus, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Columbus, Indiana, homeowners typically pay between $4,100 and $8,200 for a like-for-like central AC installation, with new systems including ductwork ranging from $6,100 to $13,300. Ductless mini-splits run $3,100–$8,200, and heat pumps $5,100–$12,300. Given the mixed-humid climate with cold winters, a gas furnace paired with a central AC is a common and efficient choice. Indiana requires a mechanical permit for AC installation, and equipment must be sized per ACCA Manual J/S. The 2018 Indiana Residential Code also mandates that any gas furnace changeout brings flue and venting up to current Mechanical Code. Local labor rates reflect the median household income of $75,114, and the typical home age (1981) often means older ductwork may need inspection or modification.

- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRequired (Manual J)
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—
Indiana Residential Code (2018 IRC base) requires HVAC equipment to be sized per ACCA Manual J/S, and gas-furnace changeouts must bring flue/venting up to current Mechanical Code even on like-for-like swaps.

AC Installation in Columbus, explained.
What Affects AC Installation Costs in Columbus
In Columbus, the final price depends on system type and efficiency. A like-for-like central AC replacement is more affordable than a full system with new ductwork. Ductless mini-splits are a strong fit for homes without existing ducts. Heat pumps cost more upfront but may qualify for federal tax credits. Older homes (median built 1981) may require duct modifications or upgrades to meet current codes, adding to labor. Permit fees and load calculations are required by Indiana code, which also affect the total.
Common AC Installation Issues in Columbus
Older Ductwork
Homes built around 1981 often have undersized or leaky ducts that need repair or replacement, increasing costs.
Code Compliance for Gas Furnaces
If replacing a gas furnace alongside AC, Indiana code requires bringing flue and venting up to current Mechanical Code, even on like-for-like swaps.
Load Calculation Requirements
Indiana mandates a Manual J load calculation to size equipment correctly, which can add to the initial assessment time and cost.
What to Expect During AC Installation in Columbus
A licensed contractor will first perform a Manual J load calculation to determine the correct system size. After obtaining a mechanical permit from the local building department, installation typically takes one to two days. The crew will remove old equipment, install the new unit, and ensure ductwork and electrical connections meet current code. Finally, they will test the system and provide upfront pricing before starting work.
