Having to drive on a hot summer day without a working air conditioner in your car is no fun, especially in states like Arizona where the average temperature can get quite high in summers.

A research study conducted by the Stanford University School of Medicine reveals that the sun can increase the temperature inside parked cars to life-threatening levels. According to the research findings, the temperature inside a car can increase by 40 degrees Fahrenheit within just an hour, regardless of the ambient temperature. And 80% of this temperature increase takes place in the initial half an hour.

Healthcare experts say that being inside the car without an AC is one of the most dangerous things during hot weather. But, unfortunately, it is often during such hot days that your car’s air conditioner starts blowing hot air instead of cold, leaving you wondering what caused it to suddenly stop working.

Here are some of the common reasons behind malfunctioning vehicle air conditioners:

1. Refrigerant Leak

The refrigerant in the car AC needs to be under the pressure of the closed loop AC system, otherwise it converts into gas and evaporates. This is exactly what happens in case of a refrigerant leak; the pressure is released causing the refrigerant to evaporate.

Unlike an oil leak, a refrigerant leak will not cause puddles of fluid under the car and hence, can be difficult for you to identify. Since the leak can occur in any part of the air conditioning system, it requires specialized training, experience, and equipment to be detected.

2. An Issue with the Electrical System

The air conditioning systems of vehicles have a number of wires, fuses, pressure switches, and relays and all these electrical components have to work in unison to keep the ACs working. Any problem in any of part of the electrical system, due to wear and tear, aging, or a defect, causes the system to shut down in order to prevent any significant damage (it’s designed that way).

3. Worn Out Compressor

As the main unit of your car’s air conditioning system, the job of a compressor is to circulate the refrigerant, so it can cool down your car’s cabin. Just like other parts of your vehicle, the compressor can wear out with time, causing contamination or failure of parts of the AC system.

Driving in uncomfortable conditions is not recommended as it can divert your attention, which could compromise your safety and put you at the risk of getting caught up in a dangerous situation.
