Repair or Replace Your AC?
A newer unit with a small fix? Repair it. An old, inefficient system that keeps failing? Do the math — replacement often wins.

Repair your AC if it's under about 10 years old and the fix is small; consider replacement if it's 12–15+ years old, uses R-22 refrigerant, has rising energy bills, or keeps needing repairs. A quick way to decide: if the repair costs more than about a third of a new system on an old unit, replacement usually wins. Call (305) 846-0155 for honest advice.
The honest math
There's no magic number, but two things drive the decision: age and repeat repairs. A one-time fix on a 6-year-old system is easy money. Several repairs a year on a 14-year-old system that's also spiking your power bill is money down the drain.
Signs it's time to replace
- 12–15+ years old — near or past the typical South Florida lifespan.
- Uses R-22 refrigerant — phased out and expensive; a leak alone can justify replacement.
- Rising energy bills — older, lower-SEER systems cost more every month.
- Frequent repairs — the failures are clustering, not one-offs.
- Uneven cooling or humidity the system can't fix.
Signs a repair makes sense
- The system is under ~10 years old.
- It's a single, affordable failure (capacitor, contactor, drain line).
- It's been well maintained and runs efficiently otherwise.

FAQ
What's the average lifespan of an AC in South Florida?
About 10–15 years — often on the shorter end near the coast, where salt air accelerates wear.
Is it worth repairing an R-22 system?
Usually not for a refrigerant leak — R-22 is phased out and costly, so replacement is often the smarter spend.
Do you offer financing on a replacement?
Yes — $0-down financing with approved credit, so a new system fits a monthly budget.
