How much does it cost to install a new AC and furnace?

Installing a new AC and furnace with Ostrom is priced case-by-case after an in-home assessment, and you’ll get a firm, upfront quote before any work begins. Total cost reflects the system design and efficiency you choose, your home’s layout, and any needed upgrades to support safe, reliable operation. A matched replacement often improves comfort and lowers maintenance, though replacing just one unit can be sensible when the other is still in good shape. Our team regularly handles these installs in the Roanoke area with right-sizing and clean workmanship. Financing and available rebates can help lower the initial outlay.

Key price drivers include:

• Equipment type: heat pump + air handler vs AC + gas furnace
• Capacity and efficiency ratings (SEER2, HSPF2, AFUE)
• Ductwork condition, rerouting, or new zones
• Electrical, refrigerant lines, thermostat, or IAQ add-ons
