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

Installing central air with new ductwork has a wide price range and is finalized only after an in‑home assessment of your home’s size, layout, and efficiency goals. The biggest cost driver is how much new ductwork is needed versus what can be reused, followed by system size from a proper load calculation. Our team frequently installs central air and ductwork in the Champaign area, including retrofits in older homes where access and sealing needs can influence labor hours. A technician-level note: when homes lack return air pathways, creating balanced returns can add materials and time but pays off in comfort and noise control. After we design the right system, we provide flat-rate pricing and can discuss available financing options.

For a precise quote, we look at these specifics during your evaluation:

• New vs. reused ducts and the number of supply/return runs
• Cooling load, tonnage, and number of comfort zones
• Efficiency tier and features (single-stage, multi-stage, variable, or heat pump)
• Add-ons like IAQ upgrades, duct cleaning, smart thermostats, or zoning
