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

The cost to install central air with ductwork is set case by case after an in‑home assessment of your layout, sizing, and system choice. Sierra Air Conditioning & Plumbing offers financing as low as $199 per month and provides free estimates and second opinions. Costs vary because a ducted system combines equipment, custom duct design, and installation labor into one project, and the final scope depends on your home and comfort goals. Our crews regularly complete full‑system installs across the Las Vegas area near Jean, so we right‑size equipment and route ducts to handle desert heat. A seasoned installer can sometimes reuse sound trunk lines and redesign only branch runs to improve airflow and reduce noise.

What drives your final price:

• Square footage and number of supply/return runs
• Attic/crawlspace access and any needed drywall work
• Electrical capacity, pad/line‑set requirements, and thermostat upgrades
• Equipment efficiency tier and any IAQ or zoning add‑ons
