The cost to install central air with new ductwork is set after an in-home assessment because equipment size, your home’s layout, and the duct design determine the price. Most of the total comes from the labor to run, seal, and balance new ducts and from sizing the AC (tonnage) to the home’s cooling load so it runs efficiently. You’ll receive a free quote with upfront pricing from Summers Plumbing Heating & Cooling before any work begins. In the Indianapolis area, our teams often retrofit older homes where careful duct routing preserves ceilings and closets while improving airflow.
Expect your quote to reflect:
- Square footage and room count, which set AC size and number of vents.
- Duct material, insulation level, and access (attic, crawlspace, finished walls).
- Electrical panel capacity and outdoor unit location options.
- Reuse of any existing ducts vs a full new build, plus add-ons like air purification.
An on-site evaluation confirms the exact scope so you can choose between a full ducted system or a ductless/heat pump alternative if it fits your home better.
