Buyers replacing or installing a 5 ton rooftop unit (RTU) typically pay between $5,000 and $18,000 for equipment and installation depending on efficiency, duct work, and roof access; the 5 ton RTU cost is driven by unit SEER, custom curb adapters, and labor complexity. This article gives U.S.-focused price ranges, per-ton and per-hour figures, and clear assumptions for each estimate.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete 5 Ton RTU Installed | $5,000 | $10,500 | $18,000 | Assumptions: 5 ton, 13-16 SEER, single-story commercial, rooftop curb present. |
| Equipment Only (Unit) | $3,000 | $6,000 | $12,000 | Per unit price varies by SEER/EER and manufacturer. |
| Labor & Rigging | $1,200 | $3,000 | $6,000 | Includes crane and crew. |
| Duct/Controls Upgrades | $500 | $1,500 | $4,000 | Repairs, VAVs, or economizer work raise costs. |

How Much Does a 5 Ton RTU Usually Cost Installed
Typical total pricing for a 5 ton RTU ranges from $5,000 to $18,000 installed, with an average near $10,500 for standard-efficiency equipment and normal rooftop access.
Expect equipment-only prices of $3,000-$12,000 and installation/labor/rigging of $1,200-$6,000 on top of the unit price.
Assumptions: commercial or large-residential conversion, 5 ton (60,000 BTU), 13-16 SEER, no major duct redesign, accessible roof within 50 ft of crane placement.
Price Breakdown: Materials, Labor, Equipment, Permits
This component table shows how contractors split quotes for a standard 5 ton RTU replacement.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $3,000-$12,000 (unit, controls, filters) | $1,000-$4,000 (techs 8-24 hrs) | $400-$2,000 (crane rental, lift) | $100-$800 | $100-$1,200 (old unit removal) |
Materials are the largest single line item; labor and rigging spike when roof access or crane time is required.

Major Variables That Change a 5 Ton RTU Quote
Site and unit specs can swing price widely: high-efficiency units and limited roof access are common drivers.
Two key numeric thresholds: SEER/EER rating (13-16 vs 17-20+ adds $1,000-$4,000) and rooftop hoist distance (>50 ft or multiple stories can add $1,000-$4,000 for crane work).
Other variables: curb type (standard vs custom adapter), added economizer or IAQ components, existing duct condition.
How Roof Access and Rigging Affect Final Price
Crane, forklift, or pulley rigging changes the installation line item dramatically; expect $400-$2,000 for simple crane lifts and $2,000-$6,000 for complex multi-crane or helicopter scenarios.
If the rooftop is obstructed or the unit must be set through a narrow stair or interior shaft, plan for the high end of rigging costs.
Assumptions: standard single-roof deck vs multi-level tight access; crane time billed hourly or as flat day rate.

Realistic Ways To Lower 5 Ton RTU Price Without Sacrificing Performance
Buyers can control costs via timing, modest spec choices, and prep work. Replacing only the compressor or coils can be cheaper than full unit swap in some cases.
Recommended cost controls: schedule during shoulder seasons, accept mid-range SEER (14-16), prepare roof and curb ahead of install, and obtain 3 competitive quotes.
Scope decisions: keep existing curb if in good condition, defer nonessential controls upgrades, and bundle multiple units for contractor volume discounts.
Typical Labor Time, Crew Size, and Hourly Rates for a 5 Ton RTU Job
Most jobs use a 2-4 person crew and take 8-24 hours on site depending on complexity; typical labor rates run $75-$125 per hour per tech.
Estimate labor math as: 8-24 hours × ($75-$125) per hour × crew size; a common labor subtotal is $1,200-$3,000.
Example: 3 techs × 10 hours × $90/hr = $2,700 labor.
Sample Quote Examples With Specs and Totals
| Scenario | Unit Specs | Labor & Rigging | Total |
|---|---|---|---|
| Basic Replace | 5 ton, 14 SEER, existing curb OK | $1,200 | $5,000-$7,000 |
| Standard Install | 5 ton, 16 SEER, crane lift, minor duct work | $2,800 | $9,500-$12,500 |
| Premium Upgrade | 5 ton, 18+ SEER, new curb, economizer, complex rigging | $4,500 | $14,000-$18,000+ |
These examples show how unit efficiency, curb work, and rigging push a project from low to high cost categories.
