02Top Causes

Why ac freezing up happens in SW FL homes

In order of frequency based on thousands of service calls in the SW FL region — the most common issues first. Your Fort Myers 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.

03Repair or Replace?

When Fort Myers 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
