Should I just repair my Florida AC instead of replacing it?
Sometimes, yes - a fairly young system with a cheap part failure is worth repairing. But past about ten years the math turns: the '$5,000 rule' plus a refrigerant that's getting scarce and expensive means one big repair on an old Florida unit often costs more than the few extra months it buys you.
The real question isn't whether it can be repaired - almost anything can - it's whether the repair buys you years or just a few more months on a system that's already on the clock.
The facts
- The widely-cited '$5,000 rule': multiply the unit's age by the repair cost, and if it's over $5,000, replace - a 10-year unit with a $600 repair is $6,000, so replacement usually wins. (Source: CBS News, the $5,000 rule)
- A central AC in Florida typically lasts about 10-15 years (coastal 7-10) and runs roughly 2,800+ hours a year, so a 12-year-old unit is already near the end of its expected life. (Source: Florida HVAC lifespan)
- If the system still uses R-410A, recharge prices have climbed 20-40% since 2024 as production is phased down; if it's an even older R-22 system, that refrigerant has been banned since 2020 and is scarce and expensive - so a refrigerant repair on an old unit is a rising bill.

- You cannot retrofit a system from one refrigerant to another, so an older R-410A or R-22 unit stays locked to the pricier, shrinking supply for the rest of its life. (Source: Refrigerant transition)
| Your situation | Usually points to |
| Under ~8 years, small part failure | Repair |
| Over ~12 years plus a big repair | Replace |
| R-22 system with a refrigerant leak | Replace - recharge is scarce and pricey |
| Age x repair cost is over $5,000 | Replace |
| Cold but clammy, short-cycling | Replace and right-size |
If your system is over ten years old and facing a big bill, see what a new one costs before you sink money into the old one. Snap the label on your outdoor unit and get one real Florida price.
