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

Question

Accepted Answer

Installing central air with new ductwork is priced after an in-home assessment because total cost depends on your home’s size, duct layout, and the efficiency level of the equipment you choose. The single biggest driver is how much new ducting is needed and how complex it is to route and balance. We provide an upfront estimate after evaluating your space, then install to manufacturer specs and local code; our Colorado team also sizes systems with altitude in mind for steady comfort. If you’re considering a heat pump, available electrification rebates can reach up to $8,000, which may lower your net project cost. Key factors that move the price up or down: - Home square footage and required cooling capacity (tonnage) - Scope of ductwork (new runs, returns, sealing, and balancing) - System type and efficiency rating - Electrical, thermostat, and drainage needs - Attic, crawlspace, or closet access constraints Schedule an on-site evaluation to receive a firm, line-item quote tailored to your home.
