How much does it cost to install central air with ductwork?

The cost to install central air with new ductwork is confirmed only after an on-site evaluation because pricing varies by home layout and equipment choices. Most homeowners see the biggest swings in price from labor and materials needed to design and run ducts throughout the house. In the Indianapolis area, our team begins with a load calculation and full duct assessment to size the system correctly before providing a firm quote. From field experience, the duct layout often dictates comfort and noise more than the outdoor unit itself. Plan on a full day for the AC portion; new ductwork adds labor that we spell out in the proposal. Free air conditioning quotes, including instant replacement quotes, are available after we gather the right details.

Key factors that change price:

• Number and length of supply/return runs and duct material choice
• System tonnage and efficiency rating (SEER2)
• Access and complexity in attics, basements, or crawlspaces
• Needed upgrades: electrical, thermostat, condensate drain, or accessories (zoning/IAQ)

Schedule an in-home evaluation to get a firm, itemized price and timeline.
