Why Car Aircon Leak Detection Matters

If your vehicle’s air conditioning isn’t blowing cold air, a refrigerant leak could be the problem. Without proper leak detection, regassing is only a temporary solution. Detecting leaks ensures your system holds refrigerant and runs at peak efficiency, saving you money in the long run.

Common Car Aircon Leak Detection Methods

1. Visual Inspection

The first step is a detailed check of hoses, fittings, and connections for obvious damage. Oil stains or residue can also often indicate refrigerant leaks.

2. Soap Bubble Test

A simple but effective method: applying soapy water to suspected areas. Bubbles form where refrigerant escapes.

3. Electronic Leak Detectors

These devices are highly sensitive and can detect even the smallest refrigerant leaks. They allow us to pinpoint the problem quickly.

4. UV Dye Testing

For very slow leaks a special fluorescent dye is added to the system along with refrigerant. Using a UV light, we can spot leaks anywhere on the system. This method is also a good option as the dye stays in the system and any future leaks can also be detected.

Signs Your Car May Have an Aircon Leak

  • AC blowing warm air instead of cold

  • Hissing sounds from the AC system

  • Visible oil residue on pipes or fittings

  • AC performance dropping quickly after a regas

Preventing Future Leaks
While not all aircon leaks can be prevented, a regular inspection every two years can help avoid common failure points. Many vehicles have design-related issues, such as poorly routed or rubbing pipes, that often lead to leaks. By bringing your car in for a checkup, we can identify and correct these problems early, ensuring your system stays reliable.
