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

Installing central air with new ductwork is priced case-by-case after a home evaluation, and Unique Indoor Comfort provides upfront pricing and free estimates for replacement quotes. The biggest driver is usually your home’s size and how complex the new duct layout must be to deliver even airflow room to room. If ducts already exist and are in good shape, costs drop; building a clean, sealed duct network from scratch adds labor, materials, and finish work. Our team regularly designs code-compliant ducted systems for Boston-area homes, including older layouts where access can be tight. One installer tip: well-placed return vents matter as much as supply runs for comfort and noise control.

What typically changes the price:

• Number of floors and rooms to serve (zones)
• Duct path difficulty and access (attic, crawlspace, finished walls)
• Equipment efficiency level and capacity selection
• Electrical upgrades and condensate/drain solutions
