Full System Replacement in Evanston, Illinois
Full System Replacement in Evanston typically costs $9,000-$18,000 installed in 2026, depending on home size and efficiency tier.
In the Evanston homes that run forced air - postwar houses and older properties retrofitted for central heat and cooling - the furnace and AC were usually installed together and now age out together. Replacing both as one matched system is the most efficient way to buy comfort and the strongest candidate for stacking Evanston's available rebates.

Full System Replacement for Evanston homes
When both units in an Evanston home are near end of life, doing them separately means paying for two installations and living with a mismatched pairing in between. A matched furnace and AC share a properly sized coil and are engineered to work as a unit, so the efficiency you pay for actually shows up in performance. We run a full load calculation on the home - accounting for additions, insulation, and the closed-off rooms common in older Evanston houses - and size the whole system to the house rather than to the equipment coming out.
The changeout happens in one visit, which matters in a dense home where basement and utility space is tight. Licensed, insured installers set the furnace and condenser, match the coil, run PVC venting and condensate to code, verify the line set and electrical. Because a matched high-efficiency system is the best candidate for stacked Nicor and ComEd rebates, we size to hit those thresholds and hand off the paperwork so the rebates actually land, with current amounts confirmed in your written estimate.

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.
