Car AC Not Cooling? 5 Common Reasons

Does the air conditioning in your car not provide comfortable cool air anymore? You are not the only one. Several drivers face challenges ranging from weak air flow to systems that do not work entirely. Such shortcomings can turn an enjoyable drive into a nightmare. Understanding what is causing your car’s AC not to function well is the initial point in solving the issue.

In this guide, we’ll explore the most frequent causes of car AC malfunctions and provide insights on potential fixes. We’ll cover situations where it’s best to seek expert help. 

Let’s get started,

Understanding Your Car AC System

Let us to begin by understanding the car AC system working that would give us necessary insights into its functionality. The car AC unit in your vehicle comprises various components functioning collectively to cool your car. It includes a compressor, condenser, evaporator, and refrigerant.

A car AC compressor pumps around the refrigerant gas in the AC while a condenser transforms it back into a liquid state from hot gas. Later, the evaporator transforms this liquid into the air which is then circulated throughout your car.

Common Reasons Why Your Car’s AC Isn’t Working

Having explained the basic aspects, let us get into the most frequent ones why your car’s air conditioning might not be working properly. It is important to note that there are problems that can be rectified easily, but others call for a specialist in car AC service.

Low Refrigerant Levels

One of the reasons why an air conditioner stops working is when it has a deficiency in refrigerant. The coolant acts as blood in a system, and when its amount goes down, your AC can’t cool the air effectively. The most common cause of this is through leaks.

Whenever you detect such a situation about possible loss of refrigerant through leakage, then always get help from experts instead of doing it yourself. They can locate the leak, repair it, and recharge your system with the correct amount of refrigerant.

Faulty Compressor

A vehicle’s air conditioning system relies primarily on its compressor. If the car AC compressor malfunctions, there will be a breakdown in air conditioning in the vehicle. Some of the common symptoms of a failed compressor include weird noises when the AC is on, as well as the failure of the AC to turn on entirely. Compressors fail because they have not been in operation for a long period as during winter months, they do so because they have run out of refrigerants and were not refilled.

Compressors also fail because they have become old, which mostly means that parts within them have either worn out or broken down with time. Changing a compressor should be done by car AC repair specialists since certain tools and equipment are needed to carry out this task.

Clogged or Dirty Condenser

Your car has an AC condenser that is situated in the front of the car and usually found in front of such things as the radiator. The major role of the radiator is to cool down your car’s refrigerant after it has been compressed. Dirt, debris, or even tiny insects can clog this component’s internal channels, thereby reducing its efficiency considerably.

The AC blowing hot air instead of cold can mean the condenser is clogged. There are times when you can as well clean the condenser on your own by simply jetting water gently on it. However, if it is severely clogged, you might need professional car AC service.

Electrical Issues

The proper function of your automobile’s AC system requires that its various electrical components work correctly, namely, that is to say, the fuses, which are often found in automobiles, but also the relays and sensors. Still, once these fail, the whole system fails.

To tell whether there’s an electrical problem with your AC, you may notice it doesn’t turn on or off sometimes or works intermittently. Changing a fuse is easy, it is a DIY job. However, troubleshooting and fixing other electrical problems often require expert knowledge.

Blocked or Leaking Evaporator

This is where it all happens! It cools the hot air from your car before it goes into the passenger compartment. If anything blocks or causes leakages in the evaporator, then expect your air conditioner (AC) not to cool properly.

Signs of evaporator issues include weak airflow from the vents or a sweet smell when you turn on the AC (which could indicate a coolant leak). Evaporator issues typically call for specialized car air conditioning maintenance since it lies deep into the dashboard.
