Commercial HVAC unit cost varies widely by capacity, system type, and installation complexity. Buyers typically pay from a few thousand dollars for small rooftop units to mid-six figures for chillers and large packaged systems, with capacity and site work driving most of the variance.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small Rooftop Unit (3–5 ton) | $9,000 | $15,000 | $25,000 | Includes basic install, 1-2 vents, standard controls |
| Medium Rooftop Unit (10–20 ton) | $25,000 | $55,000 | $120,000 | Typical for small commercial buildings |
| Packaged RTU Per Ton (installed) | $3,000/ton | $5,500/ton | $8,000/ton | Assumptions: Midwest labor rates, standard curb, normal access. |
| Chiller System (water-cooled) | $50,000 | $150,000 | $500,000 | Depends on tonnage, glycol loops, pumps, controls |
| Full HVAC Replacement for 20,000 sq ft | $120,000 | $350,000 | $900,000 | Includes ductwork, controls, multiple units |

What a Commercial HVAC Unit Costs by Size
Expect total installed prices expressed both as project totals and per-ton rates because commercial quotes combine equipment and significant site work.
Typical total price: $9,000-$900,000 depending on system and building size. Average small RTU (3–5 ton): $9,000-$25,000. Medium packaged rooftop (10–20 ton): $25,000-$120,000. Chillers and central plants: $50,000-$500,000+. Typical per-unit installed rate for packaged rooftop units is $3,000-$8,000 per ton. Assumptions: standard commercial roof curb, 1 story, normal access, standard controls.
Material, Labor, Equipment, Permits Cost Breakdown
A realistic quote separates Materials, Labor, Equipment, Permits, and Delivery/Disposal so owners can spot high-margin items.
| Cost Component | Low | Average | High | Typical Share |
|---|---|---|---|---|
| Materials (units, ductwork, controls) | $3,000 | $40,000 | $250,000 | 30–60% |
| Labor (install, electricians, HVAC techs) | $2,000 | $30,000 | $200,000 | 20–40% |
| Equipment (crane, lift rental) | $500 | $4,000 | $25,000 | 2–8% |
| Permits | $200 | $1,200 | $8,000 | 0.1–2% |
| Delivery / Disposal | $300 | $1,500 | $10,000 | 1–3% |
Assumptions: crew = 2–6 techs, hourly rates $75-$125 per hour depending on trade and city.
How Capacity and SEER Rating Change the Quote
Capacity (tons) and efficiency (SEER/EER) are primary price levers; higher SEER adds 5–30% to equipment cost but often lowers operating expense.

Example thresholds: 5–10 ton units add about $3,000-$8,000 per additional 5 tons; moving from SEER 14 to SEER 20 typically raises equipment price by $500-$2,500 per ton. Chiller sizing: under 20 tons uses packaged units; above 50 tons, expect central plant pricing to scale nonlinearly and require additional pumps and controls.
How To Lower Commercial HVAC Replacement Price
Controlling scope, timing, and material grade reduces price without sacrificing necessary performance.
Practical levers: replace only failed sections (repair vs replace), choose mid-efficiency models instead of top-tier SEER, schedule work in shoulder seasons to avoid peak contractor premiums, and bundle multiple units in one contract to reduce mobilization fees. Prepare site (clear rooftop access) to cut crane time and hourly labor.
Regional Price Differences: City, Suburb, Rural
Location changes labor and permit fees; expect 10–35% higher totals in dense urban markets compared with rural areas.
Typical deltas: urban (New York, LA, Chicago) +20–35% vs national average; suburban +5–15%; rural or secondary markets -5–15%. Permit and inspection timelines in large cities can add both cost and weeks to a project.
Typical Installation Time, Crew Size, And Rates
Installation time and crew composition directly influence labor cost estimates and scheduling.

Small RTU swap: 8–16 hours with 2–4 techs. Medium packaged system: 2–5 days with 3–6 techs. Chiller/central plant: several weeks with multi-trade crews. Hourly rates commonly $75-$125 per hour for HVAC techs and $90-$150 for union electricians in major metros.
Common Add‑Ons, Removal Fees, And Permit Costs
Quotes often exclude demolition, roof curb modification, electrical service upgrades, and refrigerant recovery — these add real costs.
Examples: old-unit disposal $200-$2,500; refrigerant recovery/reclaim $300-$2,000 depending on refrigerant type; electrical upgrade $3,000-$30,000 if service upgrade needed; curb modification or curb adapter $500-$6,000. Always confirm which line items the contractor included.
