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

Central AC pricing with new or modified ductwork is confirmed after an on-site diagnostic. Central AC replacement starts from $10,000+, and ductwork design, materials, and access can add to the total. We provide flat-rate, up-front pricing after our $179 diagnostic (waived with approved work).

What affects cost:

  • New ducts vs. reusing existing
  • Home size and number of supply/return runs
  • Attic, crawlspace, or basement access
  • Zoning or smart thermostat options
  • Removal and disposal of old equipment
