buyers typically pay for a full air conditioning and furnace replacement, with costs driven by system size, efficiency, and ductwork upgrades. The following overview covers typical price ranges and key factors that affect the total cost of a combined AC and furnace replacement in the United States.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| System Price (AC + Furnace)** | $5,000 | $9,000 | $15,000 | Includes equipment, efficiency ratings (SEER and AFUE), and basic installation. |
| Labor & Installation | $1,500 | $3,000 | $5,000 | Crew time varies by house age and ductwork needs. |
| Ductwork & Air Distribution | $1,000 | $3,000 | $7,000 | New ducts or repairs add substantial value for performance. |
| Permits & Inspections | $100 | $500 | $1,000 | Local rules may vary; some jurisdictions require inspections. |
| Disposal & Delivery | $200 | $600 | $1,200 | Old equipment removal and hauling fees. |
| Warranty & Extras | $0 | $250 | $1,000 | Extended warranties and accessories add cost. |
Assumptions: region, system size (tons), SEER/AFUE, duct status, and labor hours.
Overview Of Costs
Total project range for a full AC condenser replacement combined with a gas furnace typically runs from approximately $6,000 to $16,000, depending on efficiency and installation challenges. For a mid-range, a common bundle is around $9,500-$12,500, including a 16 SEER air conditioner and 80+ AFUE furnace. Per-unit pricing can appear as $/ton for cooling capacity and $/AFUE point for furnace efficiency, which helps compare models quickly.

What Drives Price
System efficiency (SEER) and furnace AFUE are primary price levers. Upgrading from 14 SEER to 16–18 SEER typically adds $1,000–$3,000 in equipment cost but can save more on annual energy bills. A higher AFUE (e.g., 90%–96%) increases upfront cost by about $1,000–$2,500 but reduces long-term fuel use. Other drivers include system size in tons (3–5 tons common for homes with 1,500–2,800 sq ft) and existing duct condition (leaks or insufficient supply lines can require repairs).
Ways To Save
Strategies to reduce the total cost without sacrificing comfort include selecting a single indoor and outdoor unit pairing, choosing standard efficiency where appropriate, and bundling installation services to avoid duplicative labor. Contractors may offer seasonal promotions or bundled pricing for both cooling and heating replacements, which can shave several hundred to a few thousand dollars off the project total.
Regional Price Differences
Prices vary by location due to freight, labor markets, and permit costs. In the Northeast, total replacements may land toward the higher end of the range, while the Midwest can be mid-range. The Southeast often sees moderate pricing, and rural areas may be lower but require longer travel times. Regional deltas can be ±10–25% relative to national averages depending on the market and availability.
Labor & Installation Time
Typical installation takes 1–3 days, influenced by ductwork complexity, existing wiring, and indoor coil accessibility. A standard crew includes two technicians plus an electrician if electrical upgrades are needed. Labor hours often translate to $/hour rates around $75–$125, with higher rates in urban markets or for complex retrofits.
Additional & Hidden Costs
Hidden or extra charges can include replacing old duct components, sealing and insulating ductwork, refrigerant recovery charges, and potential electrical upgrades. If a home uses non-standard venting or requires a control system upgrade, anticipate added line items. Some utilities offer rebates for high-efficiency equipment, which can offset part of the upfront cost.
Real-World Pricing Examples
Three scenario cards illustrate typical outcomes for a standard single-family home. Each scenario shows specs, labor hours, per-unit prices, and totals to help buyers compare options.
- Basic: 2-ton, 14 SEER AC with 80% AFUE furnace; standard ducts; no major upgrades. Specs: 2-ton outdoor unit, gas furnace. Labor: 1.5 days. Total: around $6,500-$8,500.
- Mid-Range: 3.5-ton, 16 SEER AC, 95% AFUE furnace; minor duct sealing; upgraded thermostat. Specs: 3.5-ton unit, medium ductwork. Labor: ~2 days. Total: around $9,500-$12,500.
- Premium: 4-ton, 18 SEER AC, 97% AFUE furnace; full duct redesign, zoned system, smart controls. Labor: ~3 days. Total: around $14,000-$18,000.
Assumptions: region, specs, labor hours.
Maintenance & Ownership Costs
Annual maintenance for a new combined system typically costs $150–$400, depending on service plans and local rates. Expect higher maintenance costs if air filters require frequent replacement due to allergies or in homes with pets. Over a 5-year horizon, plan for potential minor refrigerant checks and coil cleanings in addition to standard inspections.
Price By Region
Regional variations can affect both equipment and labor costs. Market rate differentials may mean a 10–20% spread between cities with high HVAC demand and suburban areas with more competitive pricing. Budget for local taxes and disposal fees, which can add 3–6% to the overall project.
