Posted on: 26 June 2023

Summer is peak driving season for many people, and nothing is more frustrating than not having cold AC in your car on a hot day. While it is common for AC systems to experience wear and tear, it is important to identify the signs that you need vehicle AC system repairs. Here's what you need to know.

What Are Signs You Need Vehicle AC System Repairs?

There are a few key signs that you can look for to determine if you need vehicle AC system repairs, including:

Lack of Cool Air

One of the most common red flags that you have an issue with your vehicle's AC system is when it begins to blow warm or hot air instead of cool air. If you notice a decrease in cool air from your AC vents, it may be time for repairs. It should be ice cold. If not, it can often be due to a lack of refrigerant in your AC system, a damaged compressor, or a clogged air filter. A professional technician can identify the problem and repair it.

Strange Noises

If you hear strange noises when you turn on your vehicle's AC, such as clunks or grinding, it likely means something is wrong. The noises could be due to a loose or damaged belt, bearings, or other internal parts of your AC system. Ignoring these noises can lead to more serious and costly repairs, so it's best to handle it early with a professional repair.

Unpleasant Smells

A foul odor from your vehicle's AC system could indicate multiple things like mold, mildew, or bacteria growth, which are dangerous to breathe in for extended periods. These odors can be caused by excessive moisture buildup within your AC system, which requires expert cleaning to remove the mold or bacteria and avoid health complications.


If you notice any liquid leaking in your vehicle, it could be a sign that your vehicle's AC system needs repairs. The liquid could be refrigerant, an essential component in your AC system, which can have serious health and environmental concerns when leaking. However, overheating or other mechanical issues can also cause vehicle leaks, so a thorough inspection is necessary to determine the cause.

Poor Airflow

Another indication of a faulty vehicle AC system is when the airflow is significantly weaker than usual. This lack of force could be due to issues with the blower motor, which can reduce the flow of air that fills your vehicle. Needless to say, this deficiency can leave you feeling hot and sweaty instead of cool and comfortable on your ride.
