New AC Installation Cost 2026
Homeowners typically pay a wide range for a new central air conditioning system, driven by system size, efficiency, and installation specifics. This guide provides exact price ranges, practical cost drivers, and budgeting tips for U.S. buyers. The cost and price sections include both total project ranges and per-unit estimates to help with planning.
Assumptions: region, system size in tons, SEER rating, labor hours, and permit requirements.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| System (Central AC, 2–5 tons) | $4,000 | $6,500 | $10,000 | Includes equipment and standard attic crawl installation |
| Installation Labor | $1,500 | $3,000 | $5,000 | Includes wiring, refrigerant, and wiring upgrades |
| Permits & Inspections | $100 | $500 | $2,000 | Regional variances apply |
| Materials & Accessories | $400 | $1,200 | $3,000 | Thermostats, pads, drain lines, flexduct |
| Equipment Warranties | $150 | $300 | $700 | Extended warranties may increase cost |
| Delivery & Disposal | $50 | $200 | $700 | Old-unit disposal often included in regional packages |
Overview Of Costs
Typical cost range for a complete new central AC installation in the United States spans roughly $4,000 to $12,000, with most projects landing between $6,000 and $9,500 depending on size, efficiency, and job complexity. Per-unit estimates commonly show $2,000–$4,000 for the compressor-evaporator assembly and $200–$600 per ton for labor and accessories when water-connections and ductwork are straightforward. These ranges assume a standard two-story home with existing ductwork in acceptable condition.
Cost Breakdown

|---|---|---|---|---|
| Materials | $400 | $1,200 | $3,000 | Includes furnace/air handler, condenser, filters |
| Labor | $1,500 | $3,000 | $5,000 | Install crew, refrigerant charge, duct tie-ins |
| Equipment | $2,000 | $4,000 | $7,000 | HVAC condenser and air handler or furnace combo |
| Permits | $100 | $500 | $2,000 | Local requirements; lead time varies |
| Delivery/Disposal | $50 | $200 | $700 | Old unit removal often billed separately |
| Warranties | $150 | $300 | $700 | Labor and parts warranty extensions |
| Contingency | $0 | $300 | $1,200 | Unforeseen duct repairs or upgrades |
| Taxes | $0 | $250 | $750 | Depends on local tax rules |
What Drives Price
Pricing is shaped by system efficiency (SEER), size (tons), and installation complexity. Higher SEER units save energy but cost more upfront. Larger homes demand bigger equipment or staged multi-speed systems. Roof or attic access, duct rerouting, or hidden leaks add to both material and labor costs. Niche drivers include refrigerant type, heat pump vs. conventional AC, and zoning configurations.
Factors That Affect Price
Key factors include unit capacity in tons, compressor technology, and refrigerant charges. For example, a 3-ton, 16 SEER split system commonly costs less than a 4-ton, 18 SEER model with advanced zoning. Per-region differences also influence prices through labor rates and permit fees. Regional variations can alter total project costs by ±20–30% depending on local competition and supply chains.
Ways To Save
Shop multiple quotes and verify ductwork condition before committing. Scheduling in late fall or winter generally yields lower labor demand and potential off-season discounts. Consider standard efficiency upgrades rather than premium models if the current ductwork is undersized or leaky. Bundling thermostat upgrades and maintenance plans can reduce long-term costs.
Regional Price Differences
Prices differ across regions due to labor markets and permit rules. In the Northeast, higher labor rates and stricter codes can raise totals by about 10–25% relative to the national average. The Southwest often sees moderate installation costs but higher outdoor unit pricing due to climate exposure. The Midwest typically offers mid-range pricing with frequent seasonal promotions. Expect a regional delta of roughly ±15–25% when comparing Urban, Suburban, and Rural areas.
Labor, Hours & Rates
Typical installation crews range from 1 to 3 technicians, with total labor hours commonly 8–24 hours depending on ductwork and electrical upgrades. A standard per-hour rate for installation work is around $60–$120. data-formula=”labor_hours × hourly_rate”> Major drivers include accessibility, ductwork condition, and whether existing equipment is replaced entirely or partially reused.
