Prices for furnaces and air conditioners vary by unit type, efficiency, installation complexity, and region. This guide provides clear cost ranges and practical quotes for buyers evaluating the total cost of a new furnace and AC system, including common price drivers and typical labor charges. The focus is on the cost and price you can expect to pay in the U.S. market.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace (gas, 80% AFUE) | $2,400 | $3,600 | $4,800 | Installed, mid-range efficiency, standard installation |
| Furnace (gas, 95% AFUE) | $3,000 | $4,400 | $6,000 | Higher efficiency, slightly higher labor |
| Furnace (electric) | $1,800 | $3,000 | $5,000 | Lower operating costs but higher upfront for some models |
| Air Conditioner (central, 13-15 SEER) | $2,800 | $4,400 | $6,500 | Standard SEER range, basic outdoor unit |
| Air Conditioner (high efficiency, 17-21 SEER) | $3,800 | $5,800 | $9,000 | Premium efficiency and features |
| Combined package (furnace + AC) | $6,800 | $9,800 | $15,000 | Mid-range equipment with standard installation |
Assumptions: Midwest labor rates, standard installation, residential single-family home, mid-tier equipment, ductwork in place.
Direct price ranges by system type and installation scope
When budgeting, buyers typically see two main price bands per system combo. Gas furnace with central air installations usually come in a bundled range, while electric options or high-efficiency variants push costs higher.
Gas furnace with mid-range AC (13-15 SEER) commonly runs from $6,800 to $9,800 for equipment and installation in many U.S. regions, with regional adjustments possible.
Electric furnace with mid-range AC generally falls between $5,500 and $9,000, depending on ductwork, electrical upgrades, and thermostat upgrades.
| Scenario | Low | Average | High | Notes |
|---|---|---|---|---|
| Gas furnace + 13-15 SEER AC, standard install | $6,800 | $9,800 | $12,500 | Includes basic labor and materials |
| Gas furnace + 17-21 SEER AC, premium install | $9,500 | $13,500 | $18,000 | Higher efficiency equipment and potential duct upgrades |
| Electric furnace + 13-15 SEER AC, standard install | $5,500 | $9,000 | $13,000 | Lower fuel cost but higher upfront equipment price |
| Standalone heat pump in warm regions | $4,500 | $9,000 | $14,000 | Includes outdoor unit and air handler |
Assumptions: Single-story home, standard ductwork, mid-range equipment, mid-Atlantic pricing.
Major cost components in furnace and AC quotes
A typical quote breaks into Equipment, Labor, and Permits, with minor items for delivery, disposal, and accessories. The following table shows how the total may split in practice.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Equipment (furnace + AC) | $3,000 | $5,000 | $9,000 | Unit price for both appliances |
| Labor | $1,200 | $2,400 | $4,000 | Installation crew hours, complexity |
| Permits & inspections | $150 | $500 | $1,000 | Local requirements vary |
| Delivery/Removal | $100 | $300 | $800 | Carrier fees and haul-away |
| Ductwork modifications | $500 | $1,500 | $3,500 | Needed for poor existing airflow |
| Thermostat & controls | $100 | $350 | $700 | Smart thermostat often adds cost |
| Warranty & aftercare | $0 | $200 | $600 | Some plans include extended coverage |
Assumptions: Midwest market, standard warranties, standard install path without major duct replacement.
What changes the final quote the most
Two variables commonly push costs up or down: system capacity and installation complexity. A furnace or AC sized for 2,000 square feet in a windy climate may cost less per square foot than a 3,000 square-foot home with multiple zones. Unit size in tons (AC) and BTU (furnace) directly affects equipment price and sometimes labor time. A second driver is ductwork condition; poor duct access or required plenums can add hours and materials to a project.
Assumptions: Multi-zone system in a two-story home with partial attic access.
| Driver | Impact | Typical Range | Examples |
|---|---|---|---|
| AC tonnage (new install) | Higher capacity raises equipment price | 1.5-5 tons | 3-ton system standard for 1,800-2,200 sq ft homes |
| Duct work condition | Can require new ducts or sealing | $500-$5,000 | Leaky or blocked runs add cost |
| Flat roof or attic access | Impact on labor time | 0-2 days | Limited access adds time |
Assumptions: Regional labor differences exist; access varies by home layout.
Practical ways to trim the furnace and AC price without sacrificing safety
Cost-conscious choices can keep prices in check while preserving reliability. Consider choosing mid-range SEER (13-15) AC with a compatible furnace, schedule installation in cooler months, and align with standard ductwork. Another lever is selecting a single brand for both units to reduce shipping and warranty complexity.
Bundle equipment and professional services to negotiate better terms and reduce trips for inspectors or installers.
Assumptions: Non-urgent replacement, standard electrical capacity, no major remodeling.
Regional price tendencies for furnace and AC installations
Geography influences installed costs due to labor rates, permit fees, and climate-related equipment needs. In the Southeast, mid-range gas furnaces with 14 SEER AC often trend lower than in the Northeast where higher-efficiency systems and longer wiring runs add costs. Here are regional highlights.
- Southwest: lower labor in many markets, higher permitting in some cities
- Midwest: steady ranges with occasional ductwork upgrades for older homes
- Northeast: higher prices for 95% AFUE or 17-21 SEER packages
Assumptions: Varied local codes and labor pools across regions.
Three example quotes to benchmark quotes you receive
Real-world quotes help set expectations. The examples show typical equipment sizes, labor hours, and totals.
| Quote | Equipment | Labor Hours | Per-Unit Price | Total |
|---|---|---|---|---|
| Quote A | Gas furnace 80% AFUE + 13 SEER AC | 14 | $3,800 | $7,000 |
| Quote B | Gas furnace 95% AFUE + 17 SEER AC | 18 | $6,200 | $11,800 |
| Quote C | Electric furnace + 13 SEER AC | 12 | $3,200 | $6,200 |
Assumptions: Standard single-family home, average complexity, mid-range equipment bundles.
Maintaining price accuracy over time
Prices shift with fuel costs, equipment rebates, and scheduling demand. Early-season installations may avoid rush fees, while price surges can occur during extreme weather. Planning ahead helps lock in favorable terms without compromising on safety.
Assumptions: Seasonal demand affects labor availability and pricing.
