The cost to install central air with new ductwork is confirmed only after an on-site evaluation because price depends on your home’s size and the scope of the duct design. The biggest driver is how much ducting is needed and how complex the routing is through your attic, crawlspace, or walls. A straight, short trunk line costs far less than snaking ducts through tight chases with multiple branches. If existing ducts are sound, we may reuse portions; if they’re undersized or leaky, full replacement is the smarter long-term choice. We routinely design and install complete systems in homes across the Greentown area. New installs include a manufacturer’s warranty; financing options are available for qualifying projects.
Key factors that set your final price:
- Required system capacity (load/tonnage) based on home size and insulation
- Duct length, material, and number of branches, turns, and returns
- Access limits in attics or crawlspaces and any structural accommodations
- Efficiency rating, zoning, and indoor-air upgrades like HEPA or UV
