How we localized this

We start from our national gas furnace replacement range of $2,800–$12,000 and adjust it for Miami, where costs run about the same as the national average. Evidence on Miami's cost level is genuinely mixed. A renovation-cost index (methodology: BLS wage data) puts Miami's home-improvement pricing about 5% below the U.S. average, citing a competitive general contractor market that offsets premium demand for electrical and plumbing trades. But broader cost-of-living data shows Miami running about 20% above the national average, driven mainly by housing and rent, not construction labor specifically. Separately, several contractor-marketing sites claim whole-home renovations run 35% above national — a figure we de-weight both because it's from lead-gen pages and because it conflicts sharply with the wage-based estimate. We treat Miami as about the national average pending cleaner local data, while flagging that hurricane-code compliance is a real, well-documented add-on cost for specific project types (see notes). Materials are priced roughly nationally, so treat this as an approximation — your actual price depends on your home, contractor, and project specifics.

Miami-Dade and Broward County's hurricane building code (the High-Velocity Hurricane Zone) requires impact-resistant windows and doors, which cost roughly 40–60% more than standard units — a mandatory add-on for many exterior projects, not a discretionary upgrade. Insurers increasingly require roofs under 15 years old to maintain coverage, which drives steady re-roofing demand regardless of a roof's actual condition. General labor costs are held in check by a large, competitive contractor pool for trades like painting, tile, and carpentry, while electrical and plumbing crews run busier and pricier. Permitting and effective cost can vary 10–20% by neighborhood — Coral Gables and Miami Beach, in particular, add architectural-review requirements that other parts of the metro don't have.

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: Miami×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.
