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

The cost to install central air with new or updated ductwork varies by home and is confirmed only after an on-site assessment. The biggest driver is how much ductwork is needed and the size of the system your home requires.

A correct price reflects load needs, the scope of duct design, and the efficiency level you choose; a tech will also check access, electrical capacity, and any comfort add-ons. We often see that replacing undersized or leaky ducts during installation prevents hot and cold spots later.
