Furnace Replacement in Evanston, Illinois
Furnace Replacement in Evanston typically costs $4,500-$9,000 installed in 2026, depending on home size and efficiency tier.
Most of Evanston's heat comes from boilers, but the city's converted two-flats and homes that had ductwork added over the decades run gas furnaces that are now well past their prime. Where a forced-air system exists in an Evanston house, it's usually a retrofit into a structure never designed around it - exactly the kind of furnace replacement that rewards careful sizing over a like-for-like swap.
| Smaller homes (under 1,500 sq ft) | $3,800-$7,900 |
| Typical homes (1,500-2,500 sq ft) | $4,500-$9,000 |
| Larger homes (2,500-4,000+ sq ft) | $5,000-$11,900 |

Furnace Replacement for Evanston homes
Evanston's forced-air homes tend to fall into two camps: postwar houses on the west and south sides built with ductwork from the start, and older brick homes where a gravity furnace was converted or heating was shoehorned in later. In both, the original equipment is frequently a builder-grade 80% AFUE unit that has outlived its efficient years. We begin with a load calculation rather than copying the old nameplate, because additions, insulation upgrades, and closed-off rooms change how much furnace a house actually needs today.
Replacing that furnace with a high-efficiency 90-98% AFUE condensing unit cuts gas use through a Chicago winter, but the install has to respect the house. Condensing furnaces need proper condensate drainage and PVC venting, which takes planning in a finished Evanston basement or a tight utility closet. Licensed, insured installers route the venting cleanly, haul the old unit away, and register the warranty - then point you toward the Nicor and ComEd rebates the new equipment qualifies for.

Why Evanston homes need replacement planning
Evanston is the largest city on the North Shore, dense with pre-war brick homes, two-flats, and courtyard buildings - a huge share of them still heated by steam or hot-water boilers and radiators. Much of that equipment is decades old, so the work here leans heavily toward boiler replacement and modernization, plus converting radiator homes to high-efficiency systems and adding cooling where there was never ductwork.
