Typical Installed Price for a 5-Ton Central AC and Furnace (Full Changeout)
A full 5-ton split-system changeout typically costs $8,000-$14,000 for mid-efficiency equipment and straightforward installation.
Low-end: $6,500-$8,500 for 14 SEER condenser + basic furnace or heat pump, minimal duct work, and standard electrical. Average: $10,000-$12,500 for 16 SEER condenser, matched evaporator coil, new thermostat, and moderate labor. High-end: $14,000-$18,000 for 18+ SEER, variable-speed air handler, upgraded refrigerant lines, and higher local labor rates.
Assumptions: average labor rates, 50–80 linear ft of refrigerant run, standard single-story or two-story access, typical permit needs.
Cost Components: Materials, Labor, Equipment, Permits, Delivery/Disposal
Breaking the quote into parts helps compare estimates and spot upcharges.
| Component | Low | Average | High |
|---|---|---|---|
| Equipment (condenser + coil + furnace/air handler) | $3,200 | $6,000 | $11,000 |
| Labor (installation crew, wiring, refrigerant) | $1,200 | $2,500 | $4,500 |
| Equipment Rental/Crane/Scaffold | $0 | $200 | $1,200 |
| Permits & Inspections | $75 | $250 | $800 |
| Delivery / Disposal (old unit) | $150 | $350 | $900 |

How SEER Rating, Duct Condition, and Line-Set Length Change the Price
Efficiency, duct repairs, and run length are the largest performance-related price levers.
SEER: moving from 14 SEER to 16 SEER adds about $1,000-$2,500; 18+ SEER often adds $2,500-$5,000. Ductwork: simple repairs $300-$1,200; full duct replacement $3,000-$8,000 depending on house size. Line-set length: standard 25–50 ft included; over 50 ft typically adds $200-$1,000 and may require larger refrigerant charge.
Electrical: a basic 60–amp disconnect upgrade is $200-$800; panel upgrade to handle new unit can be $1,200-$3,500.
Site Conditions and Access That Add To Final Price
Tough access, rooftop installs, or multistory rigging can double certain labor or equipment charges.
Rooftop or hard-to-reach installations commonly add $500-$2,500 for lifts or cranes. Long refrigerant runs through attic or crawlspace with obstacles may add 2–8 labor hours ($150-$1,000+). Historic homes or code-upgrade situations can trigger additional permit/inspection costs of $300-$1,500.

| Example | Specs | Labor Hours | Price |
|---|---|---|---|
| Budget Changeout | 14 SEER, matched coil, minor duct seal | 10–14 hours | $6,500-$8,500 |
| Typical Remodel | 16 SEER, new air handler, panel minor upgrade | 16–24 hours | $10,000-$12,500 |
| High-Efficiency Upgrade | 18+ SEER, variable-speed, new ducts | 24–40 hours | $14,500-$18,000 |
Practical Ways To Lower the Installed Price for a 5-Ton System
Controlling scope, timing, and material choices reduces the installed cost without guessing on quality.
Delay high-efficiency upgrades if short-term budget is key; moving from 18 SEER to 16 SEER can save $2,000-$4,000. Get multiple itemized quotes to compare labor vs. parts. Repair rather than replace sound duct runs; sealing and insulation often costs $300-$1,200 versus $3,000+ to replace. Schedule work in shoulder seasons to avoid peak contractor premiums and reduce rush fees.
How Region and Climate Affect Pricing and Where to Expect Higher Rates
Regional labor rates and climate-driven demand change installed prices by roughly ±15–30%.
Urban Northeast and West Coast typically run 10–30% above national averages due to labor and permit costs. Southern and Midwestern markets often run at or below average. High-demand summer replacement windows can spike labor by 10–25% on short notice; planning for spring/fall can lower quotes.
