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

Installing central air with all-new ductwork is priced case by case after an in-person assessment, and final pricing is confirmed on site. The biggest cost driver is the size of the home and how complex the new duct design must be to cool rooms evenly.

Our team regularly installs complete systems in the West Valley, including homes around Litchfield Park, and we size equipment and ducts for efficiency and quiet operation; in older attics, undersized return ducts often add noise and higher bills more than people expect. Free in-home estimates are available, and qualifying new systems may offer payments as low as $4.35 per day with a lifetime installation guarantee and 10-year parts and 10-year labor options.

Typical price drivers include:

• Square footage and required system tonnage
• Number and length of new supply/return runs and attic/crawlspace access
• Duct materials, sealing level, and thermostat/electrical upgrades
• Indoor air quality add-ons or insulation improvements you choose
