2. 7 Telltale Signs Your Car’s AC Needs Immediate Attention

Ignoring warning signs can turn a minor fix into a costly repair. Look out for these red flags:

1. Blowing Hot Air

This is the most obvious—and most annoying—sign. A refrigerant leak or a faulty compressor may be to blame.

2. Strange Noises When AC is On

Grinding, squealing, or clicking sounds usually signal a worn-out belt, broken fan, or debris in the system.

3. Weak or No Airflow

This could stem from clogged filters, a damaged blower motor, or ventilation issues.

4. Foul Odors

Musty smells often mean mold or mildew buildup in the evaporator. Bacteria love warm, moist places.

Oily puddles under your car? It could be refrigerant or coolant—both require fast action.

6. Dashboard Warning Lights

Modern vehicles monitor AC system health. Don’t ignore these alerts.

7. Inconsistent Temperature

If it cools one day and not the next, you're probably dealing with a failing compressor or electrical issue.

Pro Tip: Fixing small issues early can save you hundreds in major repairs down the road.
