Summer Survival Guide: Troubleshooting Your Car's AC


When the summer heat hits, there’s nothing more important than having a functional air conditioning (AC) system in your car. However, it can be incredibly frustrating when your AC starts acting up on a scorching day. To help you stay cool on the road, here’s a summer survival guide for troubleshooting and addressing common car AC problems. Call here to hire the professional mechanic for auto AC repair Dubai.

  1. No cool air? Check the refrigerant:

One of the most common AC issues is a lack of cold air. If you’re experiencing this problem, it might be due to low refrigerant levels. Insufficient refrigerant can result from leaks or simply over time. Consult your car’s manual to locate the low-pressure port and use a gauge to check the refrigerant level. If it’s low, you may need to have it topped up by a professional. Be sure to use the appropriate refrigerant type specified for your vehicle.

  1. Weak airflow? Replace the cabin air filter:

If the air from your AC vents is weak, it could be due to a clogged cabin air filter. The cabin air filter prevents dust, pollen, and other contaminants from entering your car’s interior. Over time, it can become blocked, restricting airflow. Refer to your car’s manual for the recommended replacement interval and replace the filter if needed. A new filter can significantly improve airflow and cooling performance.

  1. Odd smells? Address mold or mildew:

Unpleasant odors from your AC vents are not only bothersome but also potentially harmful. These odors can result from mold or mildew growth inside the AC system, typically due to moisture buildup. To remedy this, try running the AC on high with the windows down for a few minutes to dry out the system. If the smell persists, consider replacing the cabin air filter and cleaning the evaporator core to eliminate any lingering mold or mildew.

  1. Strange noises? Investigate the source:

Unusual noises emanating from your AC system can indicate various issues. Squealing sounds may be due to a worn-out serpentine belt or a loose AC compressor clutch. Rattling or clunking noises could signal debris in the blower motor or a failing fan motor. It’s crucial to identify and address these noises promptly, as they may lead to more significant AC problems if left unattended.
