1) The “Invisible” Clog: Condensate Drain Lines
Boca humidity means your AC pulls gallons of water out of the air daily. That moisture can feed algae and buildup inside the condensate line. When it clogs, many systems trigger a safety switch and shut off to prevent overflow.
Troubleshooting tip: If you see water pooling near the indoor air handler, stop running the system and schedule a professional drain line cleaning.
2) Frozen Coils from Restricted Airflow
It sounds backward, but your AC can freeze during a hot Boca summer. A dirty filter restricts airflow and the coil gets too cold, freezing moisture onto the unit. This often leads to weak airflow and lukewarm air.
Troubleshooting tip: Check the filter first. If it’s clogged, replace it and let the system thaw for several hours before running again.
3) Salt Air Corrosion on Outdoor Fins
Near the coast, salt carried in the breeze accelerates corrosion on condenser fins. As fins degrade, the outdoor unit can’t release heat efficiently — forcing longer run times, higher bills, and eventually poor cooling.
Troubleshooting tip: If your system struggles most on the hottest days, it may need a coil/fin cleaning and a condition check to catch corrosion early.
