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

The cost to install central air with new ductwork varies by home and is confirmed after an on-site evaluation. The biggest price driver is how much ductwork is needed and how accessible your attic or crawlspace is, followed by the efficiency and size of the equipment.

We install systems across the Apopka area and see wide ranges based on layout and comfort goals; if existing ducts are usable, pricing centers on the new system and minor modifications, while full duct design and fabrication increases labor and materials. A common field finding is older homes needing added return air paths to balance airflow, which changes labor hours more than the brand you choose. Free estimates and financing options are available, and current offers may include $500 off qualifying system installations.

• Key factors that change price: full vs. partial ductwork, home square footage, equipment efficiency/size, and electrical or thermostat upgrades.
• Signs you may need full ductwork: hot/cold rooms, undersized returns, or damaged/flex-duct with kinks or tears.
• Typical next step: load calculation and duct design to right-size equipment and verify airflow targets.
