Homeowners typically pay a broad range for a full furnace and central air installation, driven by system size, efficiency, and installation complexity. This guide provides practical price estimates in USD with low–average–high ranges and notes the main cost drivers. The term cost and price are used to help match common search intent.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace (gas) | $2,500 | $4,000 | $6,000 | Mid-efficiency to high-efficiency models; installation varies by ductwork needs. |
| Furnace (electric) | $1,500 | $3,500 | $5,500 | Lower energy cost but higher electricity use; climate matters. |
| Central air conditioner (split) | $2,800 | $5,000 | $8,000 | SEER rating impacts price; bigger homes require larger units. |
| Installation labor | $1,500 | $3,500 | $5,000 | Includes removal of old equipment and duct adjustments. |
| Ductwork refinishing/replacement | $1,000 | $3,000 | $7,000 | Attic/basement runs; complexity adds cost. |
| Permits & inspections | $100 | $500 | $1,000 | Local code requirements vary by region. |
| Total project | $6,000 | $12,000 | $25,000 | Includes equipment, labor, and basic installation. |
Assumptions: region, system size (tons), efficiency (SEER), ductwork condition, and labor availability.
Overview Of Costs
The total price for a new furnace and central air system typically ranges from about $6,000 to $25,000, with most homes falling in the $9,000–$16,000 bracket. Costs depend on equipment type (gas vs electric furnace, air conditioner efficiency), home size, ductwork state, and installation difficulty. Per-unit estimates commonly show $2,500–$6,000 for a furnace and $2,800–$8,000 for an indoor air conditioner, plus $1,500–$5,000 for labor. Labor hours often run 6–20 hours, influenced by house layout and wiring needs.
Below is a quick per-unit snapshot to help gauge budgeting, with typical assumptions about a mid-sized home in the continental U.S.
Assumptions: 2–4 ton air conditioner, 40–60 kBtu furnace, standard ductwork, single-family residential installation.

What Drives Price
System efficiency and size drive most of the cost, followed by installation complexity. Higher SEER ratings (>16) and larger tonnage (3–4 tons for many homes) raise equipment price. Ductwork condition, accessibility, and whether a retrofit is needed can add both materials and labor costs. In homes with limited space or nonstandard layouts, expect higher labor hours and potential equipment adaptations.
Cost By Region
Regional price differences can swing totals by 10–25% between regions. Coastal cities with high labor costs tend to be at the top of the range, while rural areas may fall toward the bottom. Urban markets often require city-specific permits and additional labor coordination, slightly lifting overall price compared with suburban or rural installs.
Labor, Hours & Rates
Typical scheduling and crew charges run around $75–$150 per hour, per crew member. Most full installations use a two-person crew; complex jobs can require a larger team. Time estimates vary from 6 to 20 hours depending on the home’s ductwork, electrical readiness, and whether any gas lines must be modified or added.
Additional & Hidden Costs
Hidden costs may include refrigerant recharge if an older system is reused, electrical panel upgrades, or attic/ crawlspace access improvements. Some homes require duct cleaning, sealing, or insulation upgrades to achieve optimal performance. Pest remediation or floor protection during installation can add a small, one-time fee. Always request a written breakdown to identify optional add-ons before work begins.
Prices Vs Alternatives
Alternatives such as heat pumps or mini-split systems may offer lower upfront costs in some climates, but total ownership cost varies with electricity rates and space heating needs. A heat pump may provide both heating and cooling efficiently in moderate climates, while a fossil-fuel furnace avoids electricity dependence but may incur fuel costs. Consider long-term energy usage, climate, and maintenance when comparing options.
Real-World Pricing Examples
Basic scenario: 2-ton air conditioner, 80% AFUE gas furnace, standard ductwork, typical attic installation. Total around $6,500–$9,000, with per-unit rates of $2,000–$3,500 for equipment and $1,500–$3,000 for labor.
Mid-Range scenario: 3-ton condenser with SEER 16–18, 95% AFUE furnace, moderate ductwork changes. Total around $10,000–$14,000; equipment $5,000–$7,500, labor $2,500–$4,000, permits $300–$800.
Premium scenario: High-efficiency, variable-speed blower, enhanced filtration, duct sealing and spatial accommodations for a larger home. Total around $16,000–$25,000; equipment $9,000–$14,000, labor $5,000–$9,000, specialty permits $500–$1,200.
Prices assume standard single-family homes in typical U.S. markets. Assumptions: region, tonnage, SEER, duct condition, and local permit rules.
