How Much Does HVAC Installation Cost With Ductwork Included?

Question

Accepted Answer

HVAC installation with ductwork included is quoted after an in-home consultation because total cost depends on the equipment and the scope of duct design and build. The biggest swing is usually how much new ducting is needed and how accessible the attic or crawlspace is. We verify sizing with Manual J (and related S/D design), handle permits, and meet California Title 24, then test performance and register warranties. Installations include a Lifetime Craftsmanship Warranty and a five-year labor warranty. Free estimates are available. Our team frequently completes full-system projects in the Inland Empire and plans for local permit timelines. Key cost drivers we evaluate on site: - Home size and room count that set system capacity. - Ductwork scope: new vs reuse, reroutes, sealing, insulation, and access. - Equipment type and efficiency (central AC, heat pump, ductless) and thermostat/zoning. - Electrical, code, and permit needs under Title 24.
