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

Installing central air with new ductwork typically requires an in-home assessment; total cost varies based on home size, duct design, and equipment efficiency. The biggest drivers are how much ductwork your home needs and whether access is straightforward or tight in attics or crawlspaces. A proper load calculation and right-sized equipment prevent hot spots and short cycling, which protects comfort and energy bills. We handle full-system installs and provide testing plus a homeowner walkthrough at completion, with ductless options when ducts aren’t practical. Financing, specials, and manufacturer rebate guidance can help reduce upfront cost. Our team regularly installs systems in coastal South Florida homes and accounts for humidity and salt air when advising options.

Expect your quote to reflect:

  • Square footage and layout (rooms and stories)
  • Quantity/length of supply and return runs, and register locations
  • Duct material, insulation level, and attic/crawlspace access
  • Equipment type and efficiency rating, plus thermostat and electrical needs

An on-site evaluation is the only way to confirm scope, timeline, and a firm price for your home.
