Typical Total Price For a Mid-Size Home Combo
Most U.S. homes with 1,800-2,400 sq ft pay $6,500-$10,500 for a new gas furnace and split-system air conditioner installed together. A standard 80,000–100,000 BTU furnace paired with a 2.5–3.5 ton AC typically represents the average package.
Assumptions: suburban installer rates, basic ductwork in good condition, no permit upgrades.
How The Quote Breaks Down By Material, Labor, and Equipment
Understanding invoice line items helps compare bids and spot padding.
| Materials | Labor | Equipment | Delivery/Disposal | Permit |
|---|---|---|---|---|
| $2,500-$7,500 | $900-$4,000 | $1,200-$4,500 | $100-$500 | $50-$500 |
Materials are typically the largest single portion of the total; labor and equipment make up most of the rest.
Which Specs Change The Final Quote Most
Key variables are furnace efficiency (AFUE), AC efficiency (SEER), and cooling capacity in tons; each can change the price substantially.

- Furnace AFUE: 80% models cost $1,500-$2,500; 95%-98% models cost $3,000-$6,500.
- AC SEER: 13-14 SEER condensers run $1,800-$3,000; 16-20 SEER can add $800-$2,500.
- Capacity: every additional 0.5 ton above 2.5 tons adds roughly $400-$900 depending on model and required coil size.
Upgrading from 80% AFUE to 95% AFUE and from 14 SEER to 18 SEER often increases the combo price by $2,000-$5,000.
Site Conditions And Installation Factors That Raise Costs
Hard-to-reach air handlers, long refrigerant line sets, attic furnace installs, and required duct modifications increase labor and materials.
- Long refrigerant run (>50 ft) or vertical drops: add $400-$1,200 for additional line-set and labor.
- Attic or crawlspace access adds $300-$1,200 for safety equipment and time.
- Duct repairs or replacement: $4-$12 per sq ft for patching, $2,000-$8,000 for full replacement.
Expect a 10%-40% premium on the base quote for complex access, long runs, or duct upgrades.
Practical Ways To Reduce The Combo Price
Homeowners can control scope and timing to lower costs without compromising essential performance.
- Replace both systems at once to save on overlapping labor and permit fees—combined jobs often save $500-$1,500 versus separate installs.
- Choose mid-efficiency models (90% AFUE, 14-16 SEER) to balance upfront price and operating cost.
- Prepare site: clear attic access, move stored items, and ensure 120/240V circuit availability to avoid extra labor charges.
- Get 3 written quotes with identical specs and ask for line-item bids for parts and labor.
Bundling furnace and AC replacement and doing preparatory work yourself can reduce the final invoice by several hundred dollars to over $1,000.
Regional Price Differences: City, Suburb, and Climate Effects
Prices vary by region: coastal and high-cost metro areas run 15%-40% higher than Midwest averages; hot climates favor higher SEER units and increase AC portion of the price.

| Region Type | Delta vs Midwest | Typical Combo Range |
|---|---|---|
| High-cost metro (Northeast, West Coast) | +20% to +40% | $8,000-$15,000 |
| Suburban / Sun Belt | +5% to +25% | $6,500-$12,000 |
| Midwest / Rural | Baseline | $4,500-$9,000 |
Expect to pay more where labor rates and permitting fees are higher or where higher-efficiency AC is common due to climate.
Typical Job Duration, Crew Size, and Hourly Rates
Most combo installs require a 2-4 person crew and 8-20 total labor hours, depending on complexity and ductwork.
- Small, straightforward swap: 8-12 hours with a 2-person crew.
- Complex swap with ductwork and attic work: 16-40 hours with 3-4 crew members.
- Hourly rates: $75-$125 per hour per tech is common; total labor line usually $900-$4,000.
Knowing estimated crew size and hours helps validate labor charges on bids.
