The typical cost to replace a gas furnace and air conditioner combo falls in a wide range, driven by unit efficiency, system size, and installation complexity. The price you pay often hinges on equipment ratings, home ductwork, and local labor rates. This guide presents cost estimates in clear ranges and explains what factors shape the total project price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Gas furnace + air conditioner (new, mid-efficiency to high-efficiency) | $3,800 | $5,500 | $9,500 | Includes furnace + A/C unit, basic condenser coil, and standard installation |
| Labor & installation | $1,200 | $2,800 | $4,800 | Includes removal, relocation, ductwork tweaks |
| Comfort controls / thermostats | $100 | $350 | $1,000 | Smart thermostat options add features |
| Permits & inspections | $0 | $150 | $500 | Depends on local rules |
| Materials & supplies | $200 | $700 | $2,000 | Refrigerant lines, wiring, condensate upgrades |
| Delivery/ disposal | $50 | $180 | $450 | Removal of old equipment |
| Warranty & service plan | $0 | $200 | $600 | Optional extended coverage |
| Taxes | $0 | $350 | $1,000 | State/local taxes apply |
Assumptions: region, specs, labor hours.
Overview Of Costs
Cost ranges reflect typical 2025–2025 pricing in the United States for a gas furnace and central air conditioner replacement. A common mid-range project uses a 2.0–3.5 ton, 80–95% AFUE gas furnace paired with a 14–16 SEER A/C condenser. The total project may include additional work such as duct sealing or filter upgrades. Per-unit estimates help compare options: furnace $2,000–$4,500; A/C unit $2,000–$4,000; installation labor $1,200–$3,000.
Lower-cost scenario assumes basic equipment and straightforward installation: ~ $4,000–$6,000 total. data-formula=”labor_hours × hourly_rate”> A mid-range scenario with improved efficiency and smart controls runs about $6,000–$9,000. A premium setup with high-efficiency equipment, enhanced filtration, and advanced controls can exceed $9,000–$15,000.

| Labor | $1,200 | $2,800 | $4,800 | Removal, install, ductwork |
| Equipment & Supplies | $200 | $700 | $2,000 | Filters, wiring, controls |
| Permits | $0 | $150 | $500 | Local requirements vary |
| Delivery/Removal | $50 | $180 | $450 | Old unit haul-away |
| Warranty/Service | $0 | $200 | $600 | Optional plans |
| Taxes | $0 | $350 | $1,000 | Regional tax impact |
What Drives Price
System efficiency and size dominate pricing. A furnace’s AFUE rating and an A/C’s SEER directly affect equipment cost and operating savings. Gas furnace model types (condensing vs. non-condensing) change upfront price.
Labor intensity is a major factor. Homes with limited access, complex ductwork, or multiple stories require more labor hours. data-formula=”labor_hours × hourly_rate”> This raises the total beyond base equipment costs.
Permits and local codes can add 0–$500 or more, depending on city rules and inspection requirements. Regional variations in wage rates also shift the overall price.
Ways To Save
Shop equipment with standard efficiency if long-term energy savings are acceptable; this can reduce upfront costs by several hundred dollars. A mid-range SEER with a 80–90% AFUE furnace often balances cost and efficiency.
Bundle services with a single contractor for equipment, installation, and controls to minimize trips and markup. Ask for a single, itemized quote.
Ask about rebates and seasonal promotions. Local utility rebates can lower the effective price by hundreds, sometimes more for qualifying energy-efficient packages.
Regional Price Differences
Prices vary by region due to labor markets, permit costs, and utility incentives. In the Northeast, total project costs can be 5–12% higher than the national average due to denser housing and higher permitting expenses. The Southeast and Southwest may see 0–8% lower totals thanks to milder climates and streamlined permits. Rural areas often experience lower labor rates but higher delivery charges or limited contractor availability, affecting overall pricing.
Labor & Installation Time
Typical installation takes 1–2 days for a standard single-zone, gas furnace plus central A/C. Complex homes with limited attic access or extensive ductwork can extend to 3–4 days. Labor rates commonly range $60–$110 per hour, depending on region and crew experience. The data-formula=”hours × rate”> estimate will scale with project complexity and crew size.
Real-World Pricing Examples
Basic scenario: 2.0 ton 80% AFUE gas furnace + 14 SEER A/C, standard ductwork, one-zone, 1-day install. Total: $4,000–$6,000; equipment around $2,500, labor about $1,800, permits $0–$150.
Mid-Range scenario: 3.0 ton 90% AFUE furnace + 16 SEER A/C, modest duct upgrades, programmable thermostat. Total: $6,500–$9,000; equipment $3,800–$5,000, labor $2,000–$3,000, permits $100–$350.
Premium scenario: high-efficiency 96% AFUE furnace + 18–20 SEER A/C, enhanced filtration, smart zoning, and warranty plan. Total: $9,000–$14,500; equipment $5,000–$8,500, labor $3,000–$5,000, permits $200–$500.
