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

Installing central air with new or upgraded ductwork is priced case‑by‑case after an in‑home assessment; final cost depends on system size and the scope of duct modifications. The biggest swing in price is usually how much ductwork must be added, resized, or sealed and how accessible those areas are. We install full systems in Scottsdale homes and bring airflow balancing into the bid so rooms cool evenly. Maintenance‑plan members receive 5% off single‑unit replacements and new installations carry a 2‑year workmanship warranty. A technician note: when a home has persistent hot rooms, costs often center on adding returns and correcting static pressure more than the outdoor unit itself.

Key price drivers we evaluate on site:

• Number of new supply/return runs and register locations
• Duct material choice, sealing, and insulation levels
• Equipment efficiency tier and airflow controls (e.g., variable‑speed)
• Electrical/thermostat updates and access in attic or crawl areas
