Commercial air conditioning units price varies widely by tonnage, efficiency, and installation complexity; buyers usually pay between $3,000 and $75,000 for individual units or system installs. This article lists typical total prices, per-ton rates, and the main drivers that change a commercial AC quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Rooftop Unit (RTU) 3-5 ton | $3,000 | $7,500 | $15,000 | Assumptions: Standard efficiency, basic curb, suburban site. |
| Packaged Unit 10-20 ton | $12,000 | $35,000 | $75,000 | Assumptions: Mid-efficiency, moderate duct work. |
| Split System (per ton) | $800 | $1,500 | $3,000 | Assumptions: Includes condenser and coil; excludes major ductwork. |
| Chiller (per ton) | $1,200 | $2,400 | $4,500 | Assumptions: Water-cooled, excludes pumps and piping. |

Typical Prices for Commercial AC Units and Full System Installs
Commercial buyers commonly pay $800-$3,000 per ton for equipment alone and $2,500-$7,000 per ton installed for small to medium projects.
Example totals: a 5-ton rooftop unit installed: $15,000-$35,000; a 20-ton packaged rooftop: $40,000-$90,000 depending on efficiency and duct modification. Assumptions: Continental U.S., normal access, prevalent refrigerants.
Cost Breakdown: Materials, Labor, Equipment, Permits, Disposal, and Overhead
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Overhead |
|---|---|---|---|---|---|
| $800-$4,500 per ton (unit) | $75-$150 per hour or $500-$3,500 per ton total | $300-$3,000 (cranes, lifts, rigging) | $100-$2,000 depending on city | $200-$2,500 (old unit haul & refrigerant recovery) | 10%-25% of subtotal |
Labor and rigging often equal or exceed equipment cost on rooftop replacements because of crane lifts, curb work, and multi-trade coordination.
How Tonnage, SEER/EER Rating, and Ductwork Change Final Quotes
Tonnage, efficiency rating, and existing duct condition are the three largest variables: moving from 5 to 20 tons typically multiplies base unit cost while per-ton installed rate often falls due to scale.
Numeric thresholds: small systems (1-5 tons) cost $2,500-$7,000 per ton installed; medium systems (6-20 tons) average $1,800-$5,000 per ton installed; large chillers (50+ tons) commonly drop to $1,200-$3,000 per ton installed but require significant piping and controls. Increased SEER/EER adds $100-$500 per ton for mid-efficiency, and $500-$1,500+ per ton for premium packaged units.

Practical Ways To Reduce Commercial AC Pricing Before You Buy
Controlling scope—repairing duct leaks, reusing existing rooftop curbs, and scheduling during offseason—reduces total cost significantly.
Specific levers: accept a lower SEER by one step (saves $100-$400 per ton), replace only failing components when feasible, provide contractor staging access to avoid extra rigging fees, and bundle multiple units for contractor volume discounts. Request detailed line-item quotes to avoid hidden charges for balancing, controls, or future code upgrades.
Installation Time, Crew Size, and Typical Hourly Rates
Install time scales with tonnage: expect 8-24 hours for 3-5 ton rooftop swaps and 3-7 days for 10-30 ton packaged installs including duct modifications.
Crew sizes: 2-4 techs for small rooftop swaps; 4-10 techs plus crane crew for large packaged units or chillers. Hourly labor rates vary: $75-$125 per hour for HVAC techs, $90-$200 per hour for rigging/crane services.
Regional Price Differences: Urban, Suburban, and Coastal Markets
Prices in coastal and large urban markets run 10%-40% higher than Midwest or rural areas due to labor, permits, and traffic logistics.
Typical deltas: Midwest baseline; Northeast/California +15%-35%; Southeast +5%-20%; Mountain/Plains -5%-15% below national average. Permit fees and prevailing wage rules can add $500-$5,000 depending on locality.

Common Add-Ons, Removal Fees, and Example Quotes from Real Jobs
Plan for add-ons: electrical upgrades $1,000-$12,000, curb adapters $400-$2,000, start-up and commissioning $300-$1,500, and refrigerant recovery $150-$1,000.
| Example | Specs | Labor Hours | Per-Ton Rate | Total |
|---|---|---|---|---|
| Small Retail RTU | 5 ton, 13 SEER, rooftop | 16 | $3,000 per ton | $15,000 |
| Office Packaged | 20 ton, 14 SEER, curb mods | 80 | $2,200 per ton | $44,000 |
| Light-Industrial Chiller | 60 ton, water-cooled | 200 | $1,600 per ton | $96,000 |
Assumptions: Prices include basic start-up, standard access, no major electrical service change.
