When a Florida AC system finally gives out, the first question is always the same: what’s this going to cost? Here’s an honest breakdown so you can plan.

Typical AC replacement cost

For most homes, a full central AC replacement runs about $5,500 to $12,000 installed, depending on system size, efficiency (SEER rating), and whether the air handler and ductwork also need work. A straightforward same-size swap sits at the low-to-middle of that range; a higher-efficiency system or added ductwork pushes it up.

What affects the price

Repair or replace?

If your unit is under about 10 years old and the repair is minor, fixing it is usually smarter. Once a system is 12–15+ years old, running R-22, or facing a big-ticket repair, replacement often wins on reliability and power bills.

Frequently Asked Questions

How much does a new AC unit cost in Florida?

A full central AC replacement typically runs $5,500 to $12,000 installed, depending on size, efficiency, and whether ductwork needs attention.

How long do AC units last in Florida?

With Florida\u2019s long cooling season, most systems last about 12–15 years. Regular maintenance can stretch that; heavy runtime can shorten it.
