How much does a new furnace cost in Illinois?

A new gas furnace installed in a typical Quincy-area home runs $2,500–$5,500 depending on the unit's efficiency rating (80% vs. 96% AFUE), the size needed for your home, and any ductwork modifications.

High-efficiency 96% AFUE units cost more upfront but reduce gas bills by 15–20% compared to 80% units — in Illinois winters, that difference adds up.

Vinson and Sill installs York systems and provides flat-rate quotes before any work starts.
