Homeowners typically see a combined cost to install a furnace and AC depending on system type, efficiency, and labor. The price range reflects equipment size, fuel type, and local permitting requirements. This article breaks down the cost, with clear low–average–high ranges and per-unit details to aid budgeting.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace (Gas, 80%–98% AFUE) | $2,500 | $4,200 | $7,500 | Includes basic unit, labor, and wiring |
| Air Conditioning Unit (13–21 SEER) | $3,500 | $6,000 | $10,000 | Includes outdoor condenser and coil |
| Installation Labor | $2,000 | $4,000 | $6,500 | Depending on complex ductwork |
| Permits & Codes | $100 | $400 | $1,000 | Local jurisdiction varies |
| Ductwork & Modifications | $1,000 | $4,000 | $8,000 | Home size and existing duct condition matter |
| Delivery/Removal of Old Equipment | $50 | $350 | $1,000 | Transport and disposal fees |
Assumptions: region, system size, and labor hours vary; ranges cover typical suburban installations.
Overview Of Costs
Cost ranges reflect combined equipment and labor for furnaces and central AC systems. The total typically spans $7,000 to $18,000 for standard installations in the U.S., with per-unit estimates around $2,000–$6,000 for a furnace and $3,000–$6,000 for an AC unit, plus $1,000–$5,000 for installation labor depending on ductwork and complexity. Efficiency, system size, and labor locality drive the final number. data-formula=”labor_hours × hourly_rate”>
Cost Breakdown
| Columns | Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty | Overhead | Contingency | Taxes |
|---|---|---|---|---|---|---|---|---|---|
| Furnace & AC (typical) | $2,000–$4,500 | $2,000–$4,000 | $2,000–$4,500 | $100–$1,000 | $50–$500 | $200–$900 | $500–$1,500 | $300–$1,000 | $0–$1,000 |
What Drives Price
Key price drivers include furnace AFUE rating and AC SEER level. Higher efficiency generally costs more upfront but reduces operating costs over time. Furnace AFUE ranges from 80% to 98%, and AC efficiency commonly spans 13–21 SEER. System size is driven by home square footage, insulation, and climate. A 2-ton to 3-ton AC unit pairs with a 60,000–90,000 BTU furnace in many homes, but larger homes may require more capacity. Local labor rates and permitting costs also impact the total.
Regional Price Differences
Prices vary by region due to labor markets and permit costs. In the Northeast, installed furnace + AC often runs higher, while the Midwest may be slightly lower on labor. The West Coast tends to have higher material and permit fees. Expect +/- 10–25% deltas when comparing Urban, Suburban, and Rural areas within the same region, driven by crew availability and accessibility.
Labor, Hours & Rates
Install time depends on ductwork and system configuration. Typical projects require 1–3 days of fieldwork, with labor rates ranging from $70 to $150 per hour in many markets. Complex duct reconfigurations or multiple zones can push labor toward the upper end of the range. A mini formula helps: data-formula=”estimated_hours × hourly_rate”> This yields the labor component for budgeting, separate from materials and equipment.
Seasonality & Price Trends
Prices can shift with demand and season. Demand peaks in fall and spring when replacements are common, and pricing may spike during severe weather periods or supply shortages. Off-season installations (summer dormant periods) can offer modest discounts, particularly if inventory is available and crews are not fully booked.
Real-World Pricing Examples
Basic Scenario
- Furnace: 80% AFUE gas furnace
- AC: 13 SEER unit
- Labor: standard duct changes, 1 crew, 1 day
- Assumptions: single-story home, mid-range ductwork
Specs: 2–3 ton cooling, 60–80k BTU furnace. Estimate: $7,000–$9,500 total. Assumptions: region, basic specs, standard labor hours.
Mid-Range Scenario
- Furnace: 90% AFUE gas furnace
- AC: 16 SEER unit
- Labor: additional duct modifications, 2 crews
- Assumptions: two-story home, some zoning
Specs: 3–4 ton cooling, 90k–110k BTU furnace. Estimate: $11,000–$15,500 total. Assumptions: region, mid-range specs, longer labor hours.
Premium Scenario
- Furnace: high-efficiency 98% AFUE
- AC: 21 SEER with advanced zoning
- Labor: full replacement, complex ductwork, elevated ceilings
- Assumptions: custom work, higher-end equipment
Specs: 4–5 ton cooling, 110k–130k BTU furnace. Estimate: $16,500–$25,000 total. Assumptions: region, premium specs, extended labor hours.
Additional & Hidden Costs
Hidden items can affect final budgeting. Potential extras include refrigerant charging beyond standard, to-heat pump conversions, attic or crawlspace access improvements, filtration upgrades, smart thermostats, and extended warranties. Some markets require duct cleaning or insulation upgrades. Always request a written itemized quote with contingencies clearly shown, and confirm whether taxes are included in the total.
Maintenence & Ownership Costs
Ownership costs extend beyond installation. Annual service plans, filter replacements, and occasional refrigerant checks add to long-term budgets. Typical maintenance contracts cost $150–$400 per year, while major component replacements (furnace or condenser) are not uncommon after 10–15 years, potentially ranging $2,000–$7,000 depending on parts and labor.
