It can be an extremely uncomfortable situation if your car’s AC breaks down when you need it most. For that reason, it's crucial to identify the need for repairs before the equipment fails. Aside from the total lack of cold air, there are a few early warning signs that auto mechanics look for when diagnosing vehicle AC problems. Below is a closer look at the top three indicators. 

How to Tell You Need Auto AC Repairs

1. Reduced Cooling Power

In most vehicles, the AC transitions from full strength to hot air over a series of months or even years instead of an abrupt change. As such, it's common to not notice the reduction in effectiveness until an incredibly hot and humid day. The power of the airflow from the vents may be diminished, or the temperature may be warmer than usual. Common causes of these issues include a broken or damaged fan, a clogged filter, or a disconnected hose. 

2. Odd Sounds

By the time AC became a staple automotive feature, the manufacturers had prioritized quiet cabin designs. As a result, any unusual noises are concerning. With cooling equipment, the compressor is typically the cause of troubling sounds. A damaged or worn pulley bearing is known to create a squealing sound while a clutch causes rattling. 

Odd sounds can indicate a range of mechanical issues, like a need for brake services. For that reason, the knowledge of an auto mechanic is necessary to effectively diagnose the root cause. 

3. Pooling Water

Condensation is a natural side effect of an AC system. Normally, the water buildup drains underneath the vehicle. Yet, if the outflow piping becomes blocked with debris, the moisture can leak into the cabin. Look for damp floorboards, pooling water, or stained floor mats around the driver and front passenger seats.
