The hot and humid summers on Long Island can be brutal, especially when your car’s air conditioning system isn’t working properly. A malfunctioning auto AC can make driving uncomfortable, stressful, and even unsafe. Fortunately, many common AC problems have straightforward solutions if caught early.
At Ossie’s Auto Repair in Bohemia, NY, we specialize in keeping your vehicle’s AC running smoothly during the hottest months. Here’s a guide to common auto AC issues and what you can do to fix them before the heat becomes unbearable.
Common Auto AC Problems and Their Causes
1. Weak or No Airflow
If your AC vents are blowing weak air or no air at all, it could be due to:
- A clogged cabin air filter
- Blower motor failure
- Broken or stuck blend doors that control airflow direction
2. Warm Air Coming From Vents
Warm air instead of cold can be caused by:
- Low refrigerant levels (common cause)
- Compressor failure
- Faulty pressure switches or sensors
3. Strange Noises
Hissing, rattling, or squealing noises can mean:
- Refrigerant leaks
- Loose or worn belts
- Failing compressor or blower motor
4. Bad Odors
A musty or moldy smell usually points to:
- Mold or mildew buildup in the evaporator core
- Clogged or dirty cabin air filter
What You Can Do to Fix These Issues
Check and Replace the Cabin Air Filter
A dirty filter restricts airflow and reduces AC performance. It’s typically replaced every 12,000 to 15,000 miles, but if you drive in dusty conditions, more frequent changes may be needed.
Inspect for Refrigerant Leaks
Low refrigerant is the most common cause of AC not cooling properly. At Ossie’s, we perform leak detection and recharge your system to restore proper cooling.
Clean the Evaporator and AC System
Professional cleaning of the evaporator coil and AC system can eliminate mold and unpleasant odors.
Schedule a Full AC Diagnostic
Sometimes the problem requires specialized tools to identify. Our certified technicians at Ossie’s use advanced diagnostic equipment to pinpoint issues with compressors, sensors, or electrical components.

Q: Can I add refrigerant myself?
A: It’s not recommended. Overfilling or improper handling can damage the system. Have it serviced by a professional.
Q: How often should I service my AC?
A: Annual AC inspections and maintenance before summer are ideal to prevent breakdowns.
