How Much Does It Cost to Replace an HVAC System in 2026?
How the equipment is purchased can also make a meaningful difference. For a common full-system project—such as replacing a central air conditioner and gas furnace while keeping usable ductwork—a turnkey contractor-supplied project may cost **about $11,000 to $17,000**. Purchasing a matched system through HVACDirect and paying a typical **$1,500 to $3,000 for professional installation** may lower the estimated project total to **about $5,800 to $10,500**, including a planning allowance for standard materials, permits and disposal.
