The cost to install central air with new ductwork is confirmed after an on-site assessment because total price depends on home size, system capacity, and how extensive the duct design must be. The largest driver is labor for duct layout and attic or crawlspace access, followed by equipment efficiency (SEER2) and the number of supply and return runs needed. We perform full ducted installs in the Weston area using a Free 99 Point A/C System Engineering Assessment and a free in-home estimate to build an itemized quote.
What most affects your final price:
- Duct scope: new trunk lines, returns, and register count
- Home factors: attic height, access, insulation, and existing electrical
- Equipment choices: tonnage, SEER2 rating, and indoor air quality add-ons
- Code items: permits, pads, drains, and safety float switches
A practical tech note: in older homes, truss height and clear attic pathways usually set the duct labor time more than square footage does. Current promotion: $500 off A/C installation (eligibility applies). Schedule an in-home assessment to receive a firm, written quote before any work begins.
