Average Cost to Replace Furnace and Air Conditioner 2026

Typical homeowners pay $7,000-$12,500 to replace both a furnace and central air conditioner together; individual unit pricing varies widely by capacity and efficiency. This article details the average cost, per-unit ranges, major quote components, key variables that change the final price, and practical ways to reduce the overall expense for an average U.S. single-family home.

Item	Low	Average	High	Notes
Full Furnace + AC Replacement	$5,000	$9,000	$18,000	Assumptions: 2-3 ton AC, 80k-100k BTU furnace, mid-efficiency, typical access.
Furnace Only	$2,000	$3,800	$7,000	Assumptions: mid-efficiency gas furnace, includes basic venting.
AC Condenser Only	$1,500	$4,200	$8,000	Assumptions: 1.5-4 ton split system, excludes coil if separate.
Evaporator Coil / Matching Coil	$400	$900	$1,800	Assumptions: standard matched coil for central system.

What Buyers Typically Pay For Full Furnace And AC Replacement

Combined replacement commonly ranges $5,000-$18,000 depending on unit sizes and efficiency levels; the average homeowner spends about $9,000 for a complete HVAC swap. This average assumes a 2.5-3.5 ton air conditioner, 80k-100k BTU gas furnace, matched coil, and standard ductwork in a suburban single-family home.

Assumptions: Midwest labor rates, standard materials, normal access.

Breaking Down The Quote: Materials, Labor, Equipment, Permits, Disposal, Warranty

Typical contractor quotes separate costs into tangible groups so buyers can compare line by line. Understanding each component helps spot padding or missing items in competitive bids.

Materials	Labor	Equipment	Permits	Delivery/Disposal	Warranty
$1,500-$9,000 (units & coils)	$600-$3,000 ()	$150-$800 (rigging, lift, vacuum pump)	$50-$300	$75-$500	$250-$1,200 (extended unit or labor)

How Unit Size, Efficiency Rating, And SEER/AFUE Affect The Final Price

Capacity and efficiency are primary drivers: 1.5-2 ton systems run on the low end; 3.5-5 ton for larger homes add $1,000-$4,000. Moving from a 13 SEER to a 16-18 SEER condenser typically adds $800-$2,500; stepping from an 80% AFUE furnace to 95%+ can add $600-$2,000.

Specific thresholds: choose 2.5-3 ton for 1,500-2,200 sq ft; above 3.5 ton often requires higher installation complexity and electrical upgrades.

Site Conditions That Raise The Price: Ductwork, Access, And Refridgerant Type

Complications often add significant fees. Leaky or undersized ductwork repair can add $1,000-$5,000; van-access issues or crane rentals for rooftop installs add $500-$3,000.

Switching systems that use older refrigerant (R-22) to modern R-410A/ R-454B systems may require additional coil or line set replacement costing $400-$1,200, plus disposal fees for reclaimed refrigerant.

Practical Ways To Reduce The Price On Furnace And AC Replacement

Buyers can control scope and timing. Replace both units at once to save on labor and disposal—bundling often reduces combined cost by 10%-20% versus two staged replacements.

• Accept mid-efficiency models (13 SEER, 80% AFUE) instead of top-tier to shave $1,000-$4,000.
• Prepare the site: clear attic access and provide level parking to avoid extra trip or rigging fees.
• Get 3 detailed quotes and compare line-item prices rather than totals alone.

Typical Labor Time, Crew Size, And Hourly Rates For A Replacement Job

Installation time and crew size vary by scope. A standard combined furnace and AC swap usually takes 8-16 hours with a 2-person crew; specialized rooftop jobs can take 1-3 days with larger crews.

Task	Crew	Time	Hourly Rate
Basic swap (ground-level)	2 techs	8-12 hours	$75-$125 per hour
Complex replace (duct mods, rooftop)	2-4 techs	12-36 hours	$90-$150 per hour

Regional Price Differences And What To Budget By Market

Location changes price by roughly ±20%-40% across U.S. markets. Expect coastal urban markets (Northeast, California) to be 15%-40% higher than Midwest or rural areas due to labor and permit costs.

• Midwest/rural: average combined $6,500-$9,500.
• Sunbelt/suburban: average combined $7,500-$11,000.
• High-cost metro (Northeast/West Coast): $9,500-$15,000+.

Concrete examples illustrate likely totals given specific specs. Each example lists unit sizes, labor hours, per-unit pricing, and totals.

Scenario	Specs	Labor	Per-Unit	Total
Budget Replace	2.0 ton AC, 80k BTU furnace, 13 SEER	10 hours × 2 techs	AC $1,800, Furnace $2,200, Coil $600	$5,500
Mid-Range Swap	3.0 ton AC, 95k BTU, 16 SEER	14 hours × 2 techs	AC $3,800, Furnace $3,400, Coil $900	$9,500
Premium Install	4.0 ton AC, 110k BTU, 18 SEER, rooftop	24 hours × 3 techs	AC $6,500, Furnace $5,500, Rigging $1,200	$16,800

Common Extra Charges That Often Appear On Final Invoices

Buyers should watch for add-ons that increase final cost. Common extras include electrical upgrades ($400-$2,500), gas line changes ($300-$1,200), condensate pumps ($150-$450), and surge protection or thermostats ($150-$600).

Request a written estimate listing these potential extras and whether they are required or optional before work begins.
