Homeowners typically see total project costs for an air conditioner and furnace installation range from $4,000 to $12,000, depending on system size, efficiency, and labor. The price is driven by equipment efficiency (SEER and AFUE), the complexity of the duct system, and any needed permits or additional components.
Key cost factors include unit efficiency, system size (tons and BTU), existing ductwork, installation complexity, and local permit requirements. A precise estimate requires confirming comfort goals, efficiency targets, and attic or basement access.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Equipment | $2,500 | $5,000 | $9,000 | Combination AC unit + furnace; SEER 14–21; AFUE 80–96% |
| Labor | $1,200 | $3,000 | $5,000 | Installation, refrigerant charging, wiring, controls |
| Permits | $100 | $400 | $1,000 | Local code approvals and inspections |
| Delivery/Disposal | $50 | $300 | $800 | Equipment transport and old unit disposal |
| Ductwork & Accessories | $200 | $2,000 | $5,000 | New ducts, dampers, zoning, filters |
| Taxes & Overhead | $150 | $600 | $1,000 | Varies by state and contractor |
Assumptions: region, system size, labor hours, and chosen efficiency levels.
Overview Of Costs
Typical ranges cover both the full install and the equipment. The project often spans 2–5 days, depending on ductwork and access. For a basic 3-ton system (AC about 36,000 BTU) with a standard furnace, expect about $4,500–$8,000 installed in many U.S. markets. For high-efficiency setups (SEER 18–21, AFUE 95–98%), costs commonly run $8,000–$12,000 or more. data-formula=”labor_hours × hourly_rate”>
Cost Breakdown
The following table shows how costs accumulate across major components.
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty | Overhead | Contingency | Taxes |
|---|---|---|---|---|---|---|---|---|
| $1,400–$4,000 | $1,200–$3,000 | $2,500–$5,000 | $100–$1,000 | $50–$800 | $0–$1,000 | $300–$1,000 | $400–$1,000 | $150–$1,000 |
Pricing Variables
Key price drivers include system size in tons, SEER rating for AC, AFUE for the furnace, ductwork condition, and any upgrades like smart thermostats or zoning. For example, a 3-ton unit with SEER 14–16 is typically mid-range, while a 4-ton unit with SEER 18–21 and a high AFUE furnace will push toward the upper end. Expect additional charges for complex installs or long runs of refrigerant line sets.
Ways To Save
Budget-minded strategies focus on matching system size to cooling load, choosing favorable financing, and bundling services. Consider replacing only the necessary components when existing ducts are in good condition, or selecting a mid-range SEER to balance efficiency and upfront cost. Seasonal deals or off-peak installation can provide meaningful savings.
Regional Price Differences
Prices vary by location due to labor markets and permitting costs. In the Northeast, higher permitting and labor costs can raise total project price by 5–15% compared with the Midwest. The Southeast may see lower installation time but higher refrigerant product costs, affecting final numbers by ±8%. Rural areas often have lower labor rates but may incur higher travel fees or limited contractor options.
Labor, Hours & Rates
Install time and crew costs depend on existing ductwork, accessibility, and whether a full duct redesign is needed. Typical labor for a standard retrofit ranges from 8–20 hours with a crew of 2–3 technicians. Regional hourly rates commonly fall in the $85–$150 range for licensed HVAC labor.
