Here’s how to identify and fix some of the most common AC problems South Florida drivers face—before they leave you sweating on the road.
1. AC Blowing Warm Air
One of the most common problems drivers notice is warm or inconsistent air blowing from the vents. In South Florida’s hot and humid climate, this can make even short drives uncomfortable.
What to do:
- Have the refrigerant level checked—low refrigerant is often the cause.
- Inspect for leaks in the AC system, especially in the hoses, seals, or compressor.
- Recharge the system if levels are low, but make sure any leaks are repaired first.
2. Weak Airflow from Vents
If your AC is on full blast but barely any air is coming out, the problem could be with the blower motor, fan, or cabin air filter.
What to do:
- Replace the cabin air filter, especially if it’s clogged with debris or pollen—a common issue in Boca Raton and Davie’s spring months.
- Have the blower motor and vents checked for obstructions or electrical issues.
3. Unusual Smells Coming from the Vents
A musty or moldy smell can be caused by mildew buildup in the evaporator coil or dirty cabin filters—both of which are more likely in humid climates.
What to do:
- Clean or replace the cabin air filter.
- Have a technician disinfect the AC system to remove mold or mildew inside the vents.
- Use your AC regularly to keep moisture from building up.
4. Noisy Operation
Hearing grinding, squealing, or rattling when you turn on the AC? It could point to a failing compressor, a worn belt, or debris inside the system.
What to do:
- Have the compressor clutch, belts, and pulleys inspected.
- Any unusual sounds should be checked immediately, as they can lead to larger, more expensive repairs if ignored.
5. AC System Not Turning On
If the AC doesn’t come on at all, it might be an electrical issue or a problem with the AC control system.
What to do:
- Check for blown fuses or relays.
- Have a technician run a diagnostic scan to identify any sensor or control issues.
- In European or luxury vehicles, specialized diagnostics may be required.
Final Thoughts
With the hot season just around the corner, now is the time for Boca Raton and Davie drivers to get their AC systems checked.
