How much does central air installation cost with existing ductwork?

Central air installation with existing ductwork from Del-Air is quoted after a free in-home estimate because total cost varies by system size, efficiency rating, and the condition of your existing ducts and connections. The most common cost driver is properly sized equipment matched to your home’s square footage and heat load.

A licensed technician will check airflow, inspect supply/return runs, and verify refrigerant line and electrical compatibility; a proper sizing calculation (Manual J) helps avoid paying for capacity you don’t need. Pricing is finalized once these details are confirmed and we review thermostat and ventilation needs. We install and replace central AC for homeowners throughout the DeLand area with upfront pricing. Financing is available, and current promotions include $500 off AC and heating system installations (conditions apply).
