How we localized this

We start from our national gas furnace replacement range of $2,800–$12,000 and adjust it for Chicago, where costs run about 10% above the national average. Chicago construction costs run modestly above the national average — high union labor rates are the main driver, partly offset by a deep, competitive contractor market that keeps bids in check. Recent cost increases have tracked at or slightly below the national pace. Materials are priced roughly nationally, so treat this as an approximation — your actual price depends on your home, contractor, and project specifics.

Chicago's strong union labor presence raises wage rates above the national average, though a deep, competitive contractor market keeps bids from running away. Harsh winters are hard on roofs and make furnace reliability critical, and the short building season concentrates demand from spring through fall. Older housing stock means more electrical-panel upgrades and sewer-line work than in newer metros.

How we got this

Starts from our published gas furnace replacement range of $2,800–$12,000, adjusted for:

  • Efficiency (AFUE): Standard (80% AFUE)×1
  • Furnace size: Average (60k–80k BTU · ~1,600–2,000 sq ft)×1
  • Installation: Straight swap (same location)×1
  • Area: Chicago×1.1

These figures are planning estimates compiled from public cost data on the dates shown — not quotes, bids, or guarantees. Real prices vary widely with your home, location, materials, permits, and contractor. Always get itemized written quotes from licensed local pros before budgeting or hiring.

What changes the price

  • Efficiency (AFUE) — Raises cost

    96%+ AFUE units cost more and need different venting, but burn less gas.

  • Furnace size (BTU) — Raises cost

    Bigger homes need higher heat output, which raises unit and labor cost.

  • Venting & gas line changes — Raises cost

    Switching efficiency tiers or moving the unit can require new venting or gas work.

  • Brand & warranty — Raises cost

    Premium brands and longer warranties cost more.

  • Rebates & tax credits — Lowers cost

    High-efficiency furnaces may qualify for utility rebates or federal credits.

Gas furnace replacement cost — FAQ

How much does it cost to replace a gas furnace?
Most homeowners pay $4,000–$10,000 installed, within a broader range of about $2,800 to $12,000. A typical 1,600–2,000 sq ft home lands around $4,500–$7,000 for a standard unit. Efficiency (AFUE), size, and installation complexity are the main drivers.
Is a high-efficiency furnace worth the extra cost?
A 96%+ AFUE furnace costs more upfront but burns less gas; the payback depends on your climate and gas prices, and is faster in cold regions. High-efficiency models also need different (sealed) venting, which adds to the install cost.
How much is just the furnace unit?
The furnace itself runs roughly $700–$6,200 depending on size, brand, and efficiency; high-efficiency units alone are about $2,800–$6,200. The rest of the project is labor, venting, and permits.
Should I replace my furnace and AC at the same time?
If both are old, replacing them together is common — you pay one labor mobilization and the components stay matched. If only one has failed and the other is newer, replacing just the failed unit is usually fine.
