Why ac freezing up 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.
Clogged air filter
#1 cause. A restricted filter cuts airflow over the coil, drops coil temperature below freezing, and ices up. Swap the filter — $20.
Refrigerant leak
Low charge drops coil temperature. Symptom and fix are the same as ac-not-cooling: leak repair + recharge $400–$1,100.
Closed supply vents
More than 30% of vents closed reduces airflow enough to freeze the coil. Open them all.
Dirty evaporator coil
Years of buildup insulates the coil. Professional coil cleaning runs $250–$450.
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
