Buyers replacing or installing a 3 ton AC unit with a gas furnace typically pay between $4,000 and $14,000 depending on equipment quality, ductwork, and labor. This article lists realistic price ranges, per-unit rates, and the main variables that determine the final price for a combined 3 ton air conditioner and gas furnace installation.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete 3 Ton AC + Gas Furnace System (installed) | $4,000 | $7,500 | $14,000 | Assumptions: typical single-family home, existing ductwork, standard 80–95% AFUE furnace, 13–16 SEER AC, full install. |
| 3 Ton Outdoor Condenser (equipment) | $1,800 | $3,000 | $4,500 | Per-unit equipment price; higher for 16+ SEER |
| Gas Furnace (equipment) | $1,200 | $2,400 | $4,000 | 80% AFUE low-end to 98% mod/con high-end |
| Installation Labor & Misc. | $800 | $1,800 | $4,500 | Assumptions: 6-12 hours, 2-person crew. |

Typical Total Price For A 3 Ton AC With Gas Furnace Installed
Most homeowners see a total installed price of $4,000-$14,000 for a new 3 ton air conditioner paired with a gas furnace, with $7,500 as a common estimate.
This range assumes a single-family home with adequate ductwork, average installation access, and standard 13–16 SEER cooling equipment paired with an 80–95% AFUE gas furnace.
Per-unit assumptions: a 3 ton (36,000 BTU) condenser and a furnace sized to match; premium two-stage or modulating equipment moves the price toward the high end.
Breakdown Of Quote Parts: Materials, Labor, Equipment, Permits
| Cost Component | Low | Average | High |
|---|---|---|---|
| Equipment (AC + Furnace) | $3,000 | $5,400 | $8,500 |
| Labor | $800 | $1,800 | $4,500 |
| Equipment Rental / Crane / Tools | $0 | $100 | $700 |
| Permits & Inspections | $50 | $200 | $700 |
| Disposal / Hookups / Materials | $150 | $400 | $1,000 |
Equipment and labor are the largest line items; together they typically account for 75–90% of the installed cost.
Which Site Conditions And Specs Change The Quote Most
Major price drivers include SEER rating, furnace AFUE, duct condition, and extra piping or electrical upgrades.

Three specific numeric thresholds that change quotes: SEER 13 vs SEER 16 (expect +$800-$1,800), AFUE 80% vs 95% (+$700-$1,800), and duct replacement over 200 sq ft (+$1,000-$4,000).
Other site variables: long refrigerant line sets over 50 ft often add $250-$900; conversion from electric heat to gas adds plumbing and venting costs of $1,200-$3,500.
How To Reduce The Price On A 3 Ton AC Plus Furnace Job
Cost reductions come from scope control, timing, and material choices: choose mid-efficiency models, schedule outside peak season, and keep existing ducts if sealed.
Typical savings: choosing 14 SEER over 18 SEER can cut equipment cost by $900-$2,500; replacing only the failed unit instead of full system can save $1,000-$4,000 depending on compatibility.
Ask for separate line-item quotes for equipment, labor, and permit fees; getting 3 competitive bids and accepting manufacturer-standard models reduces markups.
Regional Price Differences For Installing A 3 Ton System
Labor and permit price deltas vary by region; expect higher costs in urban and high-wage states.

| Region | Typical Installed Price | % Relative to National Avg |
|---|---|---|
| Northeast (MA, NY) | $7,500-$13,500 | +10% to +40% |
| Midwest | $5,000-$9,000 | -10% to +5% |
| South (TX, FL) | $4,500-$10,500 | -5% to +20% |
| West Coast (CA, WA) | $7,000-$14,000 | +5% to +50% |
Regional labor rates and local permitting rules typically explain most of the variance rather than equipment price alone.
Typical Labor Time, Crew Size, And Hourly Rates For This Work
Installation time for a routine 3 ton AC and furnace swap is usually 6-12 hours with a 2-person HVAC crew; complex jobs require 12-24 hours and extra technicians.
Expect labor rates of $75-$125 per hour per technician; total labor charges therefore commonly range from $800 to $4,500 depending on hours and crew size.
Assumptions: average accessibility, existing matched ductwork, no major electrical or gas line upgrades.
Three Real-World Quote Examples With Specs And Totals
| Example | Specs | Labor Hours | Equipment | Total |
|---|---|---|---|---|
| Basic Replace | 3 ton, 13 SEER, 80% furnace, reuse ducts | 8 | $3,000 | $4,900 |
| Mid Upgrade | 3 ton, 16 SEER, 95% furnace, minor duct sealing | 12 | $5,800 | $8,200 |
| Premium Install | 3 ton, 18 SEER, 98% modulating furnace, new ducts | 20 | $10,000 | $13,800 |
These examples show how equipment quality, ductwork condition, and labor hours drive the spread between low and high totals.
