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.
