When the summer months hit, there’s one question every driver dreads: Why is my car AC not working? While the do-it-yourself approach might be tempting, it’s best to leave it to the professionals at your local Kia dealer.


Issue #1: Refrigerant Leak

Keep an eye out for patches of oil around the AC unit’s hose connections. Car refrigerant is released when hoses or rubber seals break down as they’re used. When this mixes with moisture, it can corrode your car’s AC system.

When this fluid comes into contact with air, it can evaporate. Rely on a Kia professional using specialized tools to diagnose this problem and combat low refrigerant pressure.


Issue #2: Cooling Fans

Without functioning fans, the refrigerated air simply sits in the vents. The refrigerant is working, but the cooled air can’t travel throughout your car’s cabin.

Electrical issues or cracks caused by road debris might be the culprit behind your faulty cooling fans. While this problem is an inconvenience, it’s an easy fix for a Kia specialist.


Issue #3: Malfunctioning Compressor

As with a cooling fan issue, a damaged compressor can’t circulate refrigerated air around your car. This usually happens when a compressor isn’t used for long periods of time.

When warm weather finally hits and it’s time to turn on the AC again, it can shock your car’s system. While it’s recommended that drivers run their AC systems throughout the winter months, many often forget. Fortunately, a Kia technician can recognise this problem and resolve it for you.


Issue #4: Electrical Problems

A loose connection or fuse shortage can halt your AC unit in its tracks. While these problems are often easily fixed, they can cause acid build-up in your car when they go undiagnosed.

Electrical issues are tough for the average driver to recognise, so it’s best visit a trained specialist to prevent long-term damage to your car’s overall health.


Issue #5: Failing Condenser

If your AC unit is releasing hot air, it’s likely your condenser is either blocked or broken. A car’s condenser uses air that flows through your car in transit to cool the refrigerant once it’s been compressed.

If your unit isn’t releasing cool air, road debris could be blocking the condenser. Your trusted Kia professional can tell you whether your condenser needs to be unblocked or replaced.

Some car issues can be solved at home, but when it comes to your car’s AC unit, it’s best to rely on the expertise of trained Kia technicians. Visit Crain Kia of Bentonville today to talk with a skilled specialist about your car’s AC unit.
