A Trane 15-ton package unit typically costs $18,000-$34,000 for equipment alone, while a complete commercial replacement often runs $28,000-$55,000 installed. The final price depends on the unit series, efficiency, curb and duct condition, crane access, electrical work, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Trane 15-ton unit | $18,000 | $25,000 | $34,000 | Equipment only; configuration affects price |
| Installed replacement | $28,000 | $39,000 | $55,000 | Typical commercial rooftop changeout |
| Equipment price per ton | $1,200 | $1,667 | $2,267 | Calculated from unit-only range |
Assumptions: U.S. commercial building, standard packaged rooftop configuration, normal crane access, and no major duct or structural repairs.
What a Trane 15-ton rooftop unit costs installed
For a straightforward replacement, a buyer can budget about $28,000-$43,000 for a standard-efficiency Trane packaged unit and installation. A higher-efficiency model, advanced controls, difficult roof access, or extensive code work can push the total to $45,000-$55,000 or more. New construction may cost differently because ductwork, electrical service, and curb work are part of a larger project.
A 15-ton system provides nominal cooling capacity of about 180,000 BTU per hour. Equipment prices vary by model, heating type, voltage, economizer, filtration, and controls; the nameplate tonnage alone does not identify an equivalent replacement. Compare quotes using the same Trane model series, efficiency, options, and scope of work.
How equipment, crane work, and labor shape the quote
A replacement quote combines more than the rooftop unit. The breakdown below is a practical planning range for a typical U.S. commercial changeout; individual bids may group these charges differently.
| Quote component | Low | Average | High | Typical scope |
|---|---|---|---|---|
| Trane equipment | $18,000 | $25,000 | $34,000 | 15-ton packaged unit and selected options |
| Installation labor | $3,500 | $6,000 | $9,000 | Disconnect, set, connect, startup |
| Crane and rigging | $1,000 | $2,200 | $4,500 | Site access and lift duration drive price |
| Curb, electrical, controls | $1,000 | $3,000 | $7,000 | Adaptations, wiring, thermostat or controls |
| Removal and disposal | $500 | $1,200 | $2,500 | Old-unit handling and haul-away |
Labor costs rise when the changeout requires more than a direct disconnect-and-reconnect. Permit fees, sales tax, and contractor overhead may be separate or included in the quoted total.
Which capacity, efficiency, and roof conditions raise the price
Model configuration is a major price variable. A gas/electric unit, electric heat, or heat-pump arrangement can carry different equipment and connection costs. Higher efficiency may add thousands of dollars, while an economizer, upgraded filtration, smoke detector, or building-management controls can add roughly $500-$4,000 per option depending on the specified hardware and integration.
Roof and system dimensions matter too. If the existing curb does not match the new unit’s footprint, curb adapters or replacement curb work may add $800-$3,500. Duct transitions, roof patching, or electrical upgrades can add another $1,000-$8,000. A long crane reach, restricted street setup, or lift requiring permits may add $1,000-$5,000 beyond a routine pick.
Confirm the existing unit’s voltage, curb dimensions, heating type, and control interface before comparing bids. A 15-ton replacement with a 208/230-volt connection is not automatically interchangeable with a 460-volt unit, even when nominal capacity matches.
How to control the 15-ton replacement scope
Keeping a sound curb, compatible electrical connections, and working controls can reduce the project total, but only when the contractor verifies condition and code compliance. Ask for separate prices for equipment, crane, curb adaptation, controls, disposal, and repairs so optional upgrades are visible rather than bundled without explanation.
Match efficiency to operating hours and local utility rates instead of choosing a premium model by rating alone. Avoid replacing usable thermostats or adding controls that the building system cannot support. Scheduling a planned replacement during a slower period may improve contractor availability, although weather and regional demand affect any discount.
Use an itemized, like-for-like quote and preserve required safety and code work rather than cutting those items to reach a lower bid. Verify startup, refrigerant charge, airflow checks, warranty terms, and responsibility for permits in writing.
How many labor hours and crane time to expect
A direct rooftop changeout commonly takes a crew of three or four about 8-14 hours on site, often completed in one workday when the replacement is staged and access is clear. At commercial HVAC labor rates of about $100-$175 per technician-hour, this represents roughly $2,400-$9,800 in crew labor before overhead or specialized controls work. Travel, commissioning, and return visits can change the billed amount.
Crane charges are usually quoted as a mobilization or lift fee rather than a simple hourly rate. A nearby setup with a clear staging area may fall around $1,000-$2,000; a longer boom, street closure, or difficult rooftop route can exceed $4,000. Ask whether rigging, traffic control, and a second lift are included.
What removal, curb changes, and electrical work add
Removing and disposing of an old packaged unit typically adds $500-$2,500, depending on refrigerant handling, access, and hauling requirements. Curb adapters are often less expensive than rebuilding a roof curb, but the contractor must verify structural support, water sealing, and the manufacturer’s approved configuration.
Electrical modifications can be modest when the existing service matches the new unit. A new disconnect, wiring run, breaker, or service adjustment can add $500-$4,000; larger electrical or structural corrections may exceed that range. Local permits and inspections often add about $150-$1,000, though commercial jurisdictions and project scope vary. Check that the bid names any excluded permit, roof repair, or code-upgrade charges.
Why 15-ton Trane quotes differ by U.S. region
Prices in high-cost metro areas and regions with limited commercial HVAC crews can run about 10%-25% above a comparable rural or lower-cost-market project. Dense-city crane permits, union labor, restricted delivery windows, and roof access can increase costs; rural projects may instead incur travel or equipment-mobilization fees. These are planning differences, not fixed regional price lists.
Climate and operating conditions also influence selected options. A hot, humid market may prioritize humidity control and longer cooling-season operation, while colder locations may need more heating capacity or different controls. Request local bids for the same model and written scope, then compare the delivered installed total rather than equipment price alone.
Three 15-ton replacement quotes with different site conditions
| Scenario | Work and labor | Estimated total |
|---|---|---|
| Direct swap | Standard unit, 3-person crew for 9 hours, routine crane lift | $29,000-$36,000 |
| Typical retrofit | Higher-option unit, 4-person crew for 12 hours, curb adapter and controls | $37,000-$47,000 |
| Complex roof project | Premium configuration, 4-person crew for 16 hours, long crane reach and electrical work | $47,000-$60,000 |
These examples represent installed planning estimates, not guaranteed bids. The direct swap assumes compatible connections and no major repairs; the complex project includes added access and site work. When a quote falls well outside these ranges, check its model number, included options, labor scope, and exclusions before judging the price.
