Prices for a new air conditioning system with a furnace can vary widely based on brand, efficiency, system size, and installation complexity. Typical cost factors include unit price, labor, permits, and any necessary ductwork or electrical work. This article provides clear cost estimates in USD, with low–average–high ranges and practical notes to help buyers plan a budget.
Note: The cost and price data below reflect common residential installations in the United States and assume standard 3–5 ton sizing for a mid-size home, with mid-efficiency to high-efficiency equipment. Assumptions: region, specs, labor hours.

| Ductwork Modifications | $300 | $2,000 | $6,000 | Depends on leaks, length, and repairs. |
| Thermostat & Controls | $60 | $350 | $1,000 | Smart thermostats add features and cost. |
| Finish & Cleanup | $50 | $150 | $500 | Includes system startup and testing. |
| Warranty & Maintenance Plan | $0 | $200 | $600 | Annual service often recommended. |
Overview Of Costs
Cost ranges for a complete new furnace and air conditioner installation typically fall between $4,800 and $12,000, with most homeowners paying around $7,000–$9,500 for mid-range equipment and standard labor. Pricing varies primarily with system capacity (tons), efficiency (SEER/Burnham rating), and whether ductwork needs substantial replacement or relocation. Per-unit estimates commonly show $1,800–$4,000 for the furnace and $2,200–$4,500 for the air conditioner, depending on brand and efficiency.
Assumptions include a typical single-family home in the continental United States, a 3–5 ton system, and standard install conditions. Assumptions: region, specs, labor hours.
Cost Breakdown
Table below presents a practical breakdown with assumed columns for a standard installation. The table mixes total project costs with per-unit figures to aid planning.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $3,200 | $5,500 | $9,000 | Includes furnace, AC condenser, coil, filters. |
| Labor | $1,500 | $3,000 | $6,000 | Typical crew for removal and install. |
| Equipment | $3,000 | $5,000 | $9,000 | Boxed components and controls. |
| Permits | $60 | $350 | $750 | Depends on local codes. |
| Delivery/Disposal | $60 | $250 | $600 | Removal of old equipment, disposal fees. |
| Warranty | $0 | $200 | $600 | Optional extended coverage. |
| Contingency | $200 | $600 | $1,200 | Unforeseen issues (ducts, wiring). |
| Taxes | $80 | $500 | $1,200 | State and local taxes apply. |
Factors That Affect Price
Price is driven by equipment efficiency, capacity, and the complexity of installation. High-SEER models cost more upfront but can reduce long-term energy bills. A two-stage furnace and variable-speed blower add installation time and parts costs but improve comfort and efficiency. Duct size, zoning, and existing electrical service can add hours and expense.
Other numeric drivers include HVAC tonnage (3–5 tons for a typical home) and furnace AFUE rating. A larger home or retrofit that requires relocating ducts or upgrading electrical panels increases total cost. Assumptions: region, specs, labor hours.
Ways To Save
Shop for incentives such as manufacturer rebates, utility discounts, and financing options, which can reduce out-of-pocket costs by hundreds to thousands of dollars. Compare multiple bids from licensed contractors to identify best value rather than lowest price alone.
Consider partial replacements when feasible—replacing only the furnace or the condenser may reduce costs, though compatibility and efficiency should be evaluated. Scheduling installation during cooler months can lower labor demand and sometimes pricing.
Installers may offer maintenance packages that reduce future service costs and extend system life. Ensure the bid includes a full system startup, refrigerant charge, thermostat calibration, and a 1-year warranty on workmanship.
Regional Price Differences
Prices vary by region due to labor rates, permit requirements, and climate needs. In the Northeast, higher winter heating demand can push HVAC projects toward higher efficiency units, while in the Midwest, duct and insulation work can influence total costs. The West Coast often shows higher equipment costs and stricter codes.
Typical regional delta: Northeast +8–15% vs. national average; Midwest +5–12%; West Coast +10–18%.
Labor & Installation Time
Typical installation takes 1–2 days for standard replacements. Complex ductwork, multiple zones, or attic access issues can extend to 3–4 days. Labor rates commonly range from $75 to $150 per hour depending on region and contractor.
Estimated man-hours: 8–20 hours for basic installs; 25–40 hours for complex renovations.
Additional & Hidden Costs
Hidden costs may include refrigerant recharge if there’s a leak, additional electrical panel upgrades, or relocation of gas lines. Some homes require retrofitting for proper venting or upgraded insulation to meet new efficiency standards.
Typical extras: duct sealing $200–$600, refrigerant charge $150–$400, electrical work $300–$1,000.
Real-World Pricing Examples
Three scenario cards illustrate common configurations and total cost ranges. Basic represents a standard 3-ton, mid-efficiency system with minimal ductwork. Mid-Range adds a 3–4 ton high-efficiency setup with modest duct improvements. Premium includes top-tier SEER, two-stage furnace, smart controls, and significant duct tailoring.
Scenario cards:
- Basic — 3 ton, mid-efficiency, standard ductwork, minimal labor. Equipment: $3,000; Labor: $2,000; Permits: $200; Total: $5,200–$6,800.
- Mid-Range — 3.5 ton, higher SEER, light duct upgrades. Equipment: $4,500; Labor: $3,000; Permits: $350; Total: $8,000–$10,000.
- Premium — 4 ton, high SEER, two-stage furnace, enhanced zoning. Equipment: $6,000; Labor: $4,000; Permits: $500; Total: $12,000–$14,500.
Assumptions: region, specs, labor hours.
What to ask a contractor— confirm equipment compatibility with existing ductwork, confirm SEER and AFUE values, request a material breakdown, and verify whether the bid includes full startup, testing, and a one-year workmanship warranty.
