4 Signs Your Auto Air Conditioning Unit Needs a Repair

Posted By Babcock Automotive     January 2, 2023    


Your car's air conditioning unit is essential to the summer driving experience. It keeps you and your passengers comfortable and cool when it's working correctly. However, things can get uncomfortable quickly when it breaks down. Call experts like Babcock automotive services if you're experiencing any of the following problems.

1. Unusual Sounds

If you hear squealing, grinding, or rattling noises from your A/C unit, it’s a sign that something is wrong and needs repair. Here are some signs and what they indicate:

a) Squealing: A belt could be loose, or an internal component may need replacing.

b) Grinding: This is usually caused by the motor bearings wearing out, which requires the replacement of the motor itself.

c) Rattling: This can mean that there’s something caught in the fan blades, a component has come loose, or the fan motor needs to be replaced.

2. Erratic Use of the Auto Recirculate Function

Suppose your car's A/C is not cooling appropriately, and you notice it using the auto-recirculate function even when you haven't engaged it. This could indicate a problem with the compressor or other parts of the A/C system. If your vehicle has an auto-recirculate function, it should only be activated when you turn it on manually. If it is activating itself erratically, this could indicate a problem with the car's air conditioning system.

3. Diminished Airflow

If air coming out of the vents feels weak or not as strong as usual, this could indicate low refrigerant levels in the system. This could be due to a leak in the system, or it may need to be recharged. If your car's air conditioner isn't working as hard as it used to and has less airflow, have a qualified mechanic check it for leaks or other issues.

4. Water Leaks

A malfunctioning AC unit can cause condensation to build up near the evaporator coil and drip onto the floor below it if there is no drain pan installed beneath it to collect excess moisture. This can cause significant water damage if left unchecked. If there are any visible signs of water pooling near the unit, a professional should be consulted as soon as possible to identify and repair the source of the problem.

Final Words

Whether you’re driving in the peak of summer or winter, a properly functioning car air conditioner is essential for your comfort and safety. If you recognize any of the above signs, it’s time to get your AC unit checked out by an experienced automotive ac repair in San Antonio. They can help diagnose the issue and provide reliable repairs.
