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

Installing central air with new ductwork is priced after an on-site assessment, because total cost depends on system size, the scope of ducting, and your home’s layout. The biggest driver is usually how much new ductwork is needed and how accessible the install paths are, followed by equipment efficiency and any code-required upgrades. We regularly design and install full ducted systems in the Ponte Vedra Beach area, where attic access and humidity control often shape the plan. In existing homes, labor hours swing most when we must add return paths without cutting soffits. Permits and a final inspection are part of a compliant install.

When we quote, we account for:

• Number and length of new supply/return runs and register locations
• Attic/crawlspace access, insulation needs, and sealing requirements
• Electrical panel or line-voltage upgrades and thermostat controls
• Equipment efficiency (SEER2), indoor air quality add-ons, and brand choices
