Installing central air with new ductwork is priced after an on‑site evaluation because total cost depends on system size, duct design, and efficiency level. Most bids hinge on the duct scope first, then equipment tonnage and SEER2; a professional load calculation ($550, credited toward installation) sets the right size. Eligible high‑efficiency systems may qualify for up to $600 in federal tax credits, and certain instant rebates can apply at invoice. We routinely design ducted installs for coastal Pinellas homes, so we account for humidity and tight attics without cutting corners.
Expect these factors to shape your bid:
- Duct layout details: number of supply/return runs, material type, insulation R‑value, and sealing method.
- Home conditions: attic or crawl access, demo/patch needs, and return‑air upgrades.
- Electrical readiness: panel capacity, dedicated circuits, and surge protection with a volt monitor.
- Options: UV light, Media Filter $100, Drain IV $100, or smart‑thermostat wiring.
