1. The Big Picture: Total Project Cost Ranges

Recent cost data reveals how budgets vary for commercial HVAC installs in 2025.

Packaged Rooftop Units (RTUs): Total installed costs typically range from $7,500 to over $35,000
Overall Commercial HVAC Projects: Plans span $7,000 to $45,000 based on size, complexity, and accessories

When hunting for base pricing:

A 6-ton packaged unit generally costs around $3,600 to $8,000
On HVACDirect for U.S. commercial units, prices for 6-ton gas-electric models range from $4,899 to $11,316 depending on brand and specs
Though not exact, a deep dive on 10-ton models via Carrier offers brand-specific insights into higher-capacity pricing

Installing large packaged units comes with its own layer of expenses:

Basic install costs for rooftop units range from $2,500 to over $10,000, with total projects hitting anywhere between $7,500 and $35,000 (Commercial Rooftop Heating and Cooling)
Additional line items—cranes, permits, duct transitions, electrical upgrades, and smart controls—can quickly bump budgets by thousands
RTUs are generally less expensive to install compared to split systems due to fewer components and streamlined placement

Here’s how numbers stack up across core tonnages:

Unit Size	Equipment Cost (Approx.)	Total Installed Cost Estimate
6 Ton	$3,600 – $11,316	$7,500 – ~$20,000+
7.5 Ton	—	~$15,800 (RTU-specific data)
10 Ton	Higher than 6 Ton	~$19,600 (split), $~19,700 (RTU)

Location & Labor Rates: Urban areas with regulations and high skill demand drive costs up.
Unit Efficiency & Brand: Premium models with higher SEER2/IEER ratings command extra dollars.
Add-Ons: Economizers, zoning, filtration systems, or smart controls can add $2,000–$10,000+
Permitting & Access: Rooftop installations often require permits ($250–$1,500+) and crane usage ($1,000–$3,000+)
Ductwork & Roof Prep: Retrofitting costs range from $8–$15 per linear foot for ducts, and $1,000–$5,000 for roof modifications

Electric vs. Gas Operating Costs: Energy efficiency and fuel costs vary by region. High-efficiency systems enable significant savings, especially with newer refrigerants and smart controls
Rebates & Incentives: Federal tax credits, utility rebates, or accelerated depreciation can offset a chunk of CapEx.
Lifespan: With proper service, packaged units often last 10–15 years; preventive maintenance reduces long-term costs.

Small Retail (6 Ton, Entry Efficiency)
- Unit: $4,000–$6,000
- Install & accessories: $5,000–$10,000
- Total: ₹1,100,000–₹1,650,000 (~$12,000–$20,000)
Mid-Size Office (8 Ton, High Efficiency + Zoning)
- Unit: ~$10,000–$12,000
- Add-ons: $4,000–$6,000
- Permits/crane/duct tweaks: $6,000–$8,000
- Total: ₹2,900,000–₹4,000,000 (~$35,000–$45,000)
Warehouse Retrofit (10 Ton, Basic)
- Unit: $8,000–$12,000
- Install total: $8,000–$10,000
- Minimal retrofitting: $2,000–$4,000
- Total: ₹2,450,000–₹3,300,000 (~$30,000–$36,000)

6 Ton units: Expect $7,500–$20,000+ installed
8 Ton packages: Rolling up to $30,000–$45,000+
10 Ton units: Typically $20,000–$40,000+, depending on region and custom specs

Numbers vary, but with layered budgeting—equipment, install, add-ons, and operational projections—you’ll have a clear path forward.
