The formula

Cost = tons x cost per ton x efficiency multiplier + removal + permit

Installed pricing scales with tonnage, but efficiency drives more of the spread than size does. A 16 SEER2 variable-speed system routinely costs 50–70% more than a builder-grade 14 SEER2 unit of the same capacity.

Frequently asked questions

How much does it cost to replace a 3-ton AC unit?

Most 3-ton central AC replacements land between $6,500 and $11,500 installed in 2026, depending on efficiency tier and whether ductwork or the air handler is replaced at the same time.

Do I need a permit to replace an air conditioner?

Almost always yes. Mechanical permits for like-for-like equipment swaps are usually $75 to $300 and are pulled by the licensed contractor.

Is a higher SEER2 worth it?

In hot climates with long cooling seasons, stepping from 14 to 16–17 SEER2 usually pays back in 6 to 10 years. In mild climates it often does not.
