Installed Price Ranges for a 3 Ton Gas Package Unit
Expect total installed prices commonly in the $5,000-$14,000 range depending on model and site.
Typical total price: $5,000-$14,000. Average price: $8,500. Unit-only price: $2,500-$7,500 ($833-$2,500 per ton). Assumptions: standard 3-ton (36,000 Btu/h) capacity, mid-efficiency gas burner, typical suburban access.
Breakdown of Major Quote Parts for a 3 Ton Gas Package Unit
Labor and materials together usually account for 60–80% of the installed price.
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Overhead |
|---|---|---|---|---|---|
| $2,500-$6,500 (unit, curb, ducts) | $1,200-$3,500 () | $150-$600 (crane/lift rental) | $50-$500 | $100-$600 | $300-$1,200 |
How Efficiency, Brand, and Features Affect the Price
Higher SEER/Rated efficiency and brand premium can add $1,000-$4,000 to the equipment cost.
Examples: a basic 13 SEER 3-ton package unit: $2,500-$4,000; a 16–18 SEER or two-stage gas package: $4,000-$7,500. Upgrades such as variable-speed blower, modulating gas valve, or factory-installed economizer drive the price toward the high end.
Site Variables That Most Often Change the Final Quote
Roof access, curb complexity, and long gas or electrical runs create the largest variable costs.
Numeric drivers: roof curb new installation adds $600-$2,500; rooftop crane/lift time >2 hours adds $300-$1,200; gas line runs over 50 ft add $150-$700; electrical service upgrade to 200 amps can add $1,200-$3,000. Duct modifications over 200 sq ft of work add $800-$3,000.
Practical Ways To Reduce the 3 Ton Package Unit Price
Controlling scope—reuse existing curb, avoid unnecessary efficiency upgrades, and schedule in shoulder season—lowers bids.
- Reuse an existing curb and flashing when safe: saves $600-$2,000.
- Choose a mid-efficiency model (13–15 SEER) instead of top-tier high-efficiency to save $1,000-$3,000 on equipment.
- Bundle HVAC and electrical work with one contractor to reduce overhead and coordination fees.
- Obtain 3 written quotes and compare line-item costs rather than lump sums.
