How much does central air installation cost with existing ductwork?

Central air installation with existing ductwork is priced after an in-home assessment; final cost depends on the equipment selected and any prep needed to ensure the ducts and connections are ready. The biggest driver is system capacity and efficiency (SEER2), with duct condition often determining whether the job stays simple or needs added work. If your current condenser is failing and the ducts test out well, replacement typically beats sinking money into major repairs. We install central air, ductless mini-splits, and heat pumps with Straightforward Pricing, and our team regularly serves homeowners near Burley. Comfort Club members receive 5% off replacement systems.

Typical cost drivers our technicians evaluate:

  • Home size and required tonnage
  • SEER2 efficiency and equipment line
  • Duct sealing/repairs or transition fittings
  • Electrical needs, pad, drain, line set, and thermostat
