Full System Replacement in Niles, Illinois
Full System Replacement in Niles typically costs $9,000-$18,000 installed in 2026, depending on home size and efficiency tier.
Because Niles homes so often run a furnace and AC of the same vintage on the same ductwork, the two reach the end together. Replacing both as one matched system is the most cost-effective move for these postwar homes - a coil sized for both units, one installation, and the strongest position for stacked rebates.
| Smaller homes (under 1,500 sq ft) | $7,700-$15,800 |
| 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 Niles homes
When both units in a Niles home are near end of life, a matched replacement beats doing them piecemeal: the coil is sized correctly for both, the pairing runs at its rated efficiency, and you pay for one installation instead of two. We run a full load calculation, which in these tightened-up homes often points to slightly smaller, better-balanced equipment than the original - the fix for short-cycling and clammy summers.
The whole changeout is a single coordinated day. Licensed, insured installers set the furnace and condenser, match the coil, run venting and condensate to code, and verify the line set and electrical before confirming safe operation. They remove both old units and register the warranties, and we hand off the stacked Nicor and ComEd rebate paperwork the matched system qualifies for.

Why Niles homes need replacement planning
