When it comes to stepping up from a residential system like the Goodman 3‑Ton 14.5 SEER2 R‑32 bundle, moving into larger commercial or multi-zone HVAC solutions requires careful consideration. Business owners, facility managers, and large home owners often ask about Trane 5‑ton package unit price, Trane 20‑ton package unit price, and what a 20-ton Trane package unit entails. In this guide, I’ll break down costs, sizing, installation factors, and key considerations to make the right decision for your space.
Why Trane Package Units Are Popular for Larger Spaces
Package units are all-in-one outdoor HVAC systems that house the compressor, condenser, and heating/cooling coil in a single cabinet. Trane’s package units are widely used because they combine durability, efficiency, and scalability.
-
They simplify installation since the system doesn’t require a separate indoor air handler.
-
They’re built to handle higher loads, making them ideal for commercial applications or large homes with multiple zones.
-
Trane units are backed by a strong service network and long-term reliability.
Trane’s rooftop packaged systems cover capacities from 3‑25 tons, making them suitable for a wide range of commercial applications. You can explore Trane’s full commercial lineup here.
Understanding the Cost of 5‑Ton and 20‑Ton Trane Package Units
5‑Ton Trane Package Unit Price
For moderate commercial spaces, a 5-ton unit (~60,000 BTU) is often sufficient. Pricing varies depending on features, efficiency, and installation complexity:
-
Equipment alone can range between $4,400 and $5,500.
-
With installation—including rooftop curb, electrical hookups, duct modifications, and controls—total cost typically reaches $8,000‑$12,000.
The price difference often comes from optional features like variable-speed compressors, higher SEER2 ratings, or integration with building automation systems. For reference, a guide on Trane unit costs provides detailed cost breakdowns for residential and light commercial units here.
20‑Ton Trane Package Unit Price
For large commercial spaces, a 20‑ton unit (~240,000 BTU) is usually necessary. This comes with significantly higher costs:
-
Equipment alone ranges from $23,000 to $50,000, depending on efficiency and features.
-
Installation costs—including rooftop supports, crane rigging, electrical upgrades, ductwork, and controls—can add $20,000‑$30,000 or more.
-
Total installed costs can therefore range between $45,000 and $70,000+, depending on site conditions and customization.
A 20‑ton rooftop unit is designed for heavy-duty use and can handle high-load facilities like warehouses, large retail spaces, schools, or multi-tenant commercial buildings. Learn more about commercial Trane units and their specifications here.
Factors That Influence Trane Package Unit Costs
Several factors determine the overall cost of a Trane package unit:
-
Capacity / Tons – Larger tons mean larger compressors, coils, and structural components.
-
Efficiency / SEER2 Rating – Higher efficiency can add to upfront costs but pays off in energy savings.
-
Installation Complexity – Rooftop vs ground-mount, crane needs, ductwork modifications.
-
Controls / Automation – Integrating with building automation or advanced zoning systems adds cost.
-
Electrical Requirements – 3-phase power, larger disconnects, and heavier wiring for bigger units.
-
Brand Reliability – Trane’s reputation for durability often justifies the higher price.

How to Choose Between 5‑Ton and 20‑Ton Units
5‑Ton Unit is Ideal When:
-
Your commercial or large residential space is 2,500‑5,000 sq ft.
-
Cooling loads are moderate, such as offices, small retail, or light commercial operations.
-
Infrastructure (roof, ductwork, power) is already suitable.
-
Budget for installation is moderate and you don’t need extra capacity headroom.
20‑Ton Unit is Ideal When:
-
You’re cooling large facilities: 15,000‑30,000 sq ft warehouses, gyms, or schools.
-
Load is high due to large windows, high ceilings, or heavy equipment.
-
You want rooftop installations with integrated heating and cooling, multiple zones, or future growth potential.
-
Budget allows for higher upfront cost for long-term durability and efficiency.
Installation Costs & Realistic Examples
Example 5‑Ton Installation:
-
Unit cost: ~$5,500
-
Rooftop curb & platform: ~$1,000
-
Crane rigging: ~$1,500
-
Electrical setup: ~$800
-
Duct modifications: ~$1,200
-
Controls & permits: ~$1,000
-
Total installed: ~$11,500
Example 20‑Ton Installation:
-
Unit cost: ~$30,000
-
Roof support & curb: ~$5,000
-
Crane & rigging: ~$2,500
-
Electrical upgrade: ~$3,000
-
Ductwork & plenum modifications: ~$6,000
-
Controls & permits: ~$6,000
