How Much Does HVAC Installation Cost With Ductwork Included?

HVAC installation with new ductwork is priced after an in‑home assessment; final cost depends most on system size, the home’s layout, and how much ducting must be added or replaced. The biggest driver is usually the scope of duct design and fabrication, since ducts must be sized and routed to deliver proper airflow to each room.

What typically changes the price:

• System type and efficiency (Carrier options, heat pump vs furnace/AC pairing)
• Ductwork scope (full new trunks/branches vs sealing or replacing leaky sections)
• Home access and complexity (attic, crawlspace, long runs, or tight chases)
• Required electrical, controls, and thermostat upgrades

We regularly design and install ductwork in homes around Leo and the greater Fort Wayne area, and a long trunk run in a tight crawlspace can add labor faster than upsizing the equipment. If existing ducts are sound, repairing and sealing may be more cost‑effective than full replacement.
