Not So Cool: Signs of Car Air Conditioning Trouble

Integrity Auto Care • 10 April 2025

There’s nothing quite as refreshing as getting into your car on a scorching day, flipping on the air conditioning, only to have warm air stream from the vents. You might have enjoyed flawless operation for months, and then suddenly, you're trapped in a sweltering sauna on wheels. You’re definitely feeling hot, but not in a good way!


Why Isn’t My Car AC Functioning? 

So what causes the AC to stop working? There are several possibilities since the system comprises multiple components. A frequent culprit is low refrigerant levels (previously known as Freon). If this is the issue, simply topping it off isn’t a straightforward solution. Sure, it may offer a quick fix, but chances are the refrigerant will just leak out again.


The original Freon used in air conditioning systems was harmful to the Earth's ozone layer, which is why it's rarely used today. However, the current refrigerant also has an impact on global warming, making it essential to minimize any potential leaks. Therefore, a technician will investigate for leaks in your system, pinpoint their locations, and address them before replenishing the refrigerant.


Your vehicle may also feature one or more evaporators, which can fail over time, often due to leaks. The compressor is another critical component that can deteriorate, frequently as a result of age, wear, or neglect. Additionally, a technician will ensure that the blower is functioning properly since that’s what circulates the cool air into the cabin. Sometimes, the motor may fail, a relay could malfunction, or a fuse might blow. As you can see, there are a multitude of parts involved!


The good news is that your vehicle’s service center is equipped with specialized tools to recover the refrigerant and check the system's pressure—elements crucial for properly servicing the air conditioning system.
