Full System Replacement in Highland Park, Illinois
Full System Replacement in Highland Park typically costs $9,000-$18,000 installed in 2026, depending on home size and efficiency tier.
Full-system replacement is common across Highland Park's inland neighborhoods, where forced-air furnaces and central air were installed together and now retire together. Replacing both as one matched, high-efficiency system is the most cost-effective move - and Highland Park homeowners are well-positioned to stack the utility rebates it unlocks.

| Typical homes (1,500-2,500 sq ft) | $9,000-$18,000 |
| Larger homes (2,500-4,000+ sq ft) | $10,100-$23,800 |

Full System Replacement for Highland Park homes
When a Highland Park home's furnace and AC are both near end of life, a matched system beats replacing them piecemeal: the coil is sized correctly for both units, the pairing runs at its rated efficiency, and you pay for one installation instead of two. We run a full load calculation on the home, which in these insulated, updated houses frequently points to smaller, better-matched equipment than what's coming out - the fix for short-cycling and uneven rooms.
The whole changeout happens in one coordinated visit. The install crew sets both units, matches the coil, handles venting and condensate, and verifies the electrical. A matched high-efficiency system is the strongest candidate for stacking Nicor and ComEd rebates, and when a heat pump anchors a dual-fuel setup it opens up ComEd's heat-pump rebate too - we size to those thresholds and hand off the paperwork so nothing is left on the table, with current amounts confirmed in your estimate.

Why Highland Park homes need replacement planning
Highland Park spans grand older homes in Ravinia and along the lake as well as mid-century and newer construction inland, so replacements run the full range - boilers in the historic core, furnace-and-AC systems in postwar neighborhoods, and heat pumps where homeowners want efficiency and rebates. Older systems here are common and frequently overdue.
