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

Question

Accepted Answer

The cost to install a new AC and furnace is confirmed after an in‑home assessment because homes and installation needs vary widely. Most pricing reflects the equipment selected and how complex the installation will be. Our team frequently retrofits Oak Park vintage homes and plans around plaster walls and tight chases to avoid unnecessary disruption. In many older homes, choosing small‑duct high‑velocity or ductless options can change the budget more than the brand itself. If both units are aging, replacing together often reduces labor overlap and ensures matched performance; if one unit is still healthy, a targeted replacement can be sensible. Free, no‑obligation installation estimates are available. Key factors that affect price: - Load‑based system size and efficiency ratings (SEER2, AFUE) - Ductwork condition or need for small‑duct high‑velocity/ductless solutions - Line‑set, venting/flue, gas, condensate, and electrical upgrades - Home age constraints and finish work to protect plaster or woodwork Schedule an in‑home evaluation to receive a firm, itemized quote tailored to your home.
