Average Cost of Furnace and Air Conditioner Replacement 2026
Replacing a furnace and air conditioner is a major home upgrade with price swings driven by equipment efficiency, system size, and installation complexity. Typical costs hinge on the furnace type, AC tonnage, SEER rating, and local labor rates. The following figures focus on installed costs in the United States and include common price drivers to help buyers budget accurately.
Assumptions: regional labor markets, standard 14- to 16-SEER air conditioner, mid-range furnace with 80–95 AFUE, skilled install crew, and standard ductwork.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace (Gas or Electric) | $3,000 | $5,000 | $8,000 | Mid-range efficiency; includes basic installation |
| Air Conditioner (Central, 3–5 ton) | $2,500 | $4,500 | $9,000 | Standard 14–16 SEER; higher SEER adds $1,000–$2,000 |
| System Installation | $1,000 | $2,500 | $4,000 | Labor, permits, disposal, and system integration |
| Controls & Accessories | $200 | $600 | $2,000 | Thermostats, zoning, smart features |
| Delivery/Disposal | $100 | $300 | $1,000 | Disposal of old equipment; refrigerant handling |
| Permits & Codes | $0 | $150 | $1,000 | Local permit requirements vary |
Overview Of Costs
Total project ranges typically fall between about $5,500 and $15,000, with most homes spending $9,000–$12,000 for a mid-range furnace and 16 SEER AC. Per-unit estimates commonly appear as $1,800–$2,500 per ton for AC plus $3,000–$6,000 for a mid-range furnace, depending on efficiency and installation complexity. Assumptions include a standard two-unit replacement (furnace + AC) in a single home with existing ductwork in good condition.
Cost Breakdown
Table shows how money typically distributes across major cost centers. Expect materials and labor to dominate the budget, with permits and disposal adding a smaller but not negligible share.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $3,000 | $5,000 | $9,000 | Furnace unit plus AC coil and refrigerant charge |
| Labor | $1,000 | $2,500 | $4,500 | Crew hours, complexity, system matching |
| Equipment | $400 | $1,200 | $2,000 | Tools, refrigerant handling, parts |
| Permits | $0 | $150 | $1,000 | Dependent on city/municipality |
| Delivery/Disposal | $100 | $300 | $1,000 | Old equipment removal, refrigerant reclaim |
| Warranty & Overhead | $100 | $400 | $1,000 | Manufacturer warranty; contractor overhead |
What Drives Price
Two primary drivers affect total cost: system efficiency and size. Furnace efficiency is measured by AFUE, with higher-efficiency models costing more upfront but offering lower operating costs. For air conditioning, SEER (Seasonal Energy Efficiency Ratio) governs price and long-term savings; higher SEER adds upfront cost but reduces monthly cooling bills. System size, typically 2–5 tons for many homes, directly scales both equipment and labor costs. Other factors include ductwork condition, existing gas lines or electrical upgrades, and the need for new condensate drainage or zoning controls.
Factors That Affect Price
Regional differences influence pricing due to labor markets and permit fees. Local code requirements for refrigerant handling and system commissioning can add or reduce costs. The energy source (gas vs electric) and installation difficulty—such as retrofit installs with duct sealing or large homes—also shift the total. Seasonal demand can raise prices during peak heating or cooling months, while off-season work may yield modest savings.
Ways To Save
Smart budgeting can cut costs without sacrificing reliability. Compare at least three reputable installers to gauge a fair price range and ask for a detailed written estimate that itemizes components. Consider high-efficiency equipment if long-term energy savings offset the higher upfront price. Bundling services, such as financing options, extended warranties, or maintenance agreements, can reduce effective annual costs. Duct sealing, insulation upgrades, and smart thermostat incentives may lower annual energy use and improve comfort.
Regional Price Differences
Prices differ across the United States due to labor markets and material costs. In the samples below, three distinct regions illustrate typical deltas: Northeast urban, Midwest suburban, and Southern rural. Urban centers may experience higher labor rates and permit fees, while rural areas may see more favorable pricing but longer lead times.
- Urban Northeast: +10% to +20% vs national average depending on city; higher permit and disposal costs.
- Midwest Suburban: near national average with modest ±5% variation due to labor rates.
- Southern Rural: often 5%–15% lower for labor, but supply chain delays can raise timing costs.
Labor, Hours & Rates
Labor costs reflect crew size and install duration. A typical replacement may require a 1–2 day job for a standard home. Estimated labor ranges: $1,000–$2,500 for the furnace portion, and $1,000–$2,000 for the AC installation, depending on ductwork and wiring needs. Special scenarios, such as added zoning, smart controls, or removal of an old rooftop unit, can increase labor hours and rates.
Real-World Pricing Examples
Three scenario cards illustrate common outcomes. Assumptions include completing both furnace and AC replacement in a single visit with a mid-range equipment package.
- Basic — 2-ton AC, mid-range furnace, standard ductwork, 14 SEER AC, 80 AFUE furnace. Labor: 14–18 hours. Parts: standard coil, air handler, thermostat. Total: $6,000–$7,500. Per-unit: AC $2,000–$2,500/ton; Furnace $3,000–$4,000.
- Mid-Range — 3–3.5 ton AC, 90 AFUE furnace, 16 SEER. Labor: 18–28 hours. Upgrades: improved filtration, basic zoning. Total: $9,000–$12,000.
- Premium — 4–5 ton high-efficiency system, 18–20 SEER, advanced zoning, smart thermostat, enhanced filtration. Labor: 28–40 hours. Total: $14,000–$20,000.
Assumptions: region, specs, labor hours.
