AC Not Cooling in Fort Lauderdale, FLTop causes, real repair costs, when to replace instead
An AC that runs but doesn't cool in Florida usually points to one of four issues: low refrigerant from a leak, a dirty condenser coil, a failing capacitor on the outdoor unit, or undersized equipment that can't keep up with a hot afternoon. Repair runs $180–$1,200 depending on which it is.

Why ac not cooling happens in South FL homes
In order of frequency based on thousands of service calls in the South FL region — the most common issues first. Your Fort Lauderdale technician will diagnose the real cause in under 30 minutes.
Low refrigerant / leak
If your system is 8+ years old and needs a refrigerant top-off, you likely have a slow leak. Patching the leak and recharging runs $400–$1,100 in Florida.
Dirty condenser coil
The outdoor unit can't release heat if the coil is clogged with pollen, grass, or pet hair. A full coil wash runs $180–$300 and often restores 30% of cooling overnight.
Failed capacitor
The most common AC failure in Florida. A bad run capacitor stops the compressor or fan motor. Replacement: $180–$450 including labor.
Undersized system
A system sized for milder weather can't catch up on a 95°F afternoon. If your AC is 10+ years old and always struggled, it may have been wrong from day one.
When Fort Lauderdale homeowners should replace instead
Repair makes sense when
- System is under 10 years old
- Repair is under $1,500
- No major component (compressor/coil) failed
- Rest of the system is healthy
Replacement makes sense when
- System is 12+ years old
- Repair would exceed $2,500
- Compressor or evaporator coil is the failed part
- Utility rebates + IRA tax credit swing the math
